In this work, we report an on-chip aptasensor for ochratoxin A (OTA) toxin detection that is based on a graphene field-effect transistor (GFET). Graphene-based devices are fabricated via large-scale technology, allowing for upscaling the sensor fabrication and lowering the device cost. The sensor assembly was performed through covalent bonding of graphene\uffe2\uff80\uff99s surface with an aptamer specifically sensitive towards OTA. The results demonstrate fast (within 5 min) response to OTA exposure with a linear range of detection between 4 ng/mL and 10 pg/mL, with a detection limit of 4 pg/mL. The regeneration time constant of the sensor was found to be rather small, only 5.6 s, meaning fast sensor regeneration for multiple usages. The high reproducibility of the sensing response was demonstrated via using several recycling procedures as well as various GFETs. The applicability of the aptasensor to real samples was demonstrated for spiked red wine samples with recovery of about 105% for a 100 pM OTA concentration; the selectivity of the sensor was also confirmed via addition of another toxin, zearalenone. The developed platform opens the way for multiplex sensing of different toxins using an on-chip array of graphene sensors.

Indeed, process and technological limitations have made HPC uncompetitive with respect to consolidated processes/technologies so far. In this manuscript, these issues are critically discussed and reviewed with the aim of providing the reader with a realistic picture of the prospective application of HPC in wastewater treatment. Accordingly, consolidated and new photocatalysts (among which the visible active ones are attracting increasing interest among the scientific community), along with preparation methods, are reviewed to understand whether, with increased process efficiency, these methods can be realistically and competitively developed at industrial scale.

The application of HPC in urban and industrial wastewater treatment and possible energy recovery by hydrogen production are discussed in terms of current limitations and future prospects. Despite the fact that HPC has been studied for the removal of pollutants in aqueous matrices for two decades, its use in wastewater treatment is still at a 'technological research' stage. In order to accelerate the adoption of HPC at full scale, it is advisable to focus on investigations under real conditions and on developing/improving pilot-scale reactors to better investigate scale-up conditions and the potential to successfully address specific challenges in wastewater treatment through HPC.

Metasurfaces have emerged as a breakthrough platform for manipulating light at the nanoscale and enabling on\uffe2\uff80\uff90demand optical functionalities for next\uffe2\uff80\uff90generation biosensing, imaging, and light\uffe2\uff80\uff90generating photonic devices. However, translating this technology to practical applications requires low\uffe2\uff80\uff90cost and high\uffe2\uff80\uff90throughput fabrication methods. Due to the limited choice of materials with suitable optical properties, it is particularly challenging to produce metasurfaces for the technologically relevant mid\uffe2\uff80\uff90infrared spectral range. These constraints are overcome by realizing functional metasurfaces on almost completely transparent free\uffe2\uff80\uff90standing metal\uffe2\uff80\uff90oxide membranes. A versatile nanofabrication process is developed and implemented for highly efficient dielectric and plasmonic mid\uffe2\uff80\uff90infrared metasurfaces with wafer\uffe2\uff80\uff90scale and complementary metal\uffe2\uff80\uff93oxide\uffe2\uff80\uff93semiconductor (CMOS)\uffe2\uff80\uff90compatible manufacturing techniques. The advantages of this method are revealed by demonstrating highly uniform and functional metasurfaces, including high\uffe2\uff80\uff90Q structures enabling fine spectral selectivity, large\uffe2\uff80\uff90area metalenses\uffc2\uffa0with\uffc2\uffa0diffraction\uffe2\uff80\uff90limited focusing capabilities, and birefringent metasurfaces providing polarization control at record\uffe2\uff80\uff90high conversion efficiencies.\uffc2\uffa0 Aluminum plasmonic devices and their integration into microfluidics for real\uffe2\uff80\uff90time and label\uffe2\uff80\uff90free mid\uffe2\uff80\uff90infrared biosensing of proteins and lipid vesicles are further demonstrated. The versatility of this approach and its compatibility with mass\uffe2\uff80\uff90production processes bring infrared metasurfaces markedly closer to commercial applications, such as thermal imaging, spectroscopy, and biosensing.Integrating photoactive proteins with synthetic nanomaterials holds great promise in developing optoelectronic devices whereby light, captured by a antenna protein, is converted to a modulated electrical response. The protein\uffe2\uff80\uff93nanomaterial interface is critical to defining optoelectronic properties; successful integration of bionanohybrids requires control over protein attachment site and a detailed understanding of its impact on device performance. Here, the first single\uffe2\uff80\uff90walled carbon nanotube (SWCNT) bio\uffe2\uff80\uff90optoelectronic transistor enabled by the site\uffe2\uff80\uff90specific direct interfacing with a green fluorescent protein (GFP) via genetically encoded phenyl azide photochemistry is reported. The electrical behavior of individual semiconducting SWCNTs depends on the protein residue coupling site and provides the basis to design eco\uffe2\uff80\uff90friendly phototransistors and optoelectronic memory. Attachment at one GFP residue proximal to the chromophore produces a wavelength\uffe2\uff80\uff90specific phototransistor. The bio\uffe2\uff80\uff90transistor can be switched off in less than 38 s with responsivity up to 7 \uffc3\uff97 103 A W\uffe2\uff88\uff921 at 470\uffc2\uffa0nm. Attachment via a second residue distal to the chromophore generates optoelectronic memory that show rapid and reproducible conductivity switching with up to 15\uffe2\uff80\uff90fold modulation that is restored on the application of a gate voltage. Therefore, photoactive proteins, especially GFP, can be realized as a key material for novel single\uffe2\uff80\uff90molecule electronic and photonic devices.The molecular alignment of platinum(II) octaethyl porphyrin (PtOEP) crystals evaporated on KBr (see atomic force microscopy image, Figure) can be readily changed from perpendicular to parallel by changing the substrate temperature. The field\uffe2\uff80\uff90effect mobility of transisitors prepared using epitaxially grown PtOEP films aligned perpendicularly to a substrate is 100 times higher than that of those of parallel alignment.Low\uffe2\uff80\uff90loss nanostructured dielectric metasurfaces have emerged as a breakthrough platform for ultrathin optics and cutting\uffe2\uff80\uff90edge photonic applications, including beam shaping, focusing, and holography. However, the static nature of their constituent materials has traditionally limited them to fixed functionalities. Tunable all\uffe2\uff80\uff90dielectric infrared Huygens' metasurfaces consisting of multi\uffe2\uff80\uff90layer Ge disk meta\uffe2\uff80\uff90units with strategically incorporated non\uffe2\uff80\uff90volatile phase change material Ge3Sb2Te6 are introduced. Switching the phase\uffe2\uff80\uff90change material between its amorphous and crystalline structural state enables nearly full dynamic light phase control with high transmittance in the mid\uffe2\uff80\uff90IR spectrum. The metasurface is realized experimentally, showing post\uffe2\uff80\uff90fabrication tuning of the light phase within a range of 81% of the full 2\uffcf\uff80 phase shift. Additionally, the versatility of the tunable Huygen's metasurfaces is demonstrated by optically programming the spatial light phase distribution of the metasurface with single meta\uffe2\uff80\uff90unit precision and retrieving high\uffe2\uff80\uff90resolution phase\uffe2\uff80\uff90encoded images using hyperspectral measurements. The programmable metasurface concept overcomes the static limitations of previous dielectric metasurfaces, paving the way for \uffe2\uff80\uff9cuniversal\uffe2\uff80\uff9d metasurfaces and highly efficient, ultracompact active optical elements like tunable lenses, dynamic holograms, and spatial light modulators.Polarization is a fundamental property of electromagnetic waves that plays a key role in many physical phenomena and applications. Schemes to manipulate it are revisited with the emergence of metasurfaces, which have brought multi\uffe2\uff80\uff90functionalities straightforwardly. However, this has come at the expense of design complexity that relies strongly on field theory. Here, an ingenious strategy of modular design is proposed to construct subwavelength multifunctional polarization control devices. Chiral metasurfaces with different handedness are first proposed and regarded as modules. The versatile polarization controller can thus be obtained with the combination of different modules. These experiments demonstrate that the well\uffe2\uff80\uff90designed polarization controller possesses reconfigurable functionality, and various broadband polarization and amplitude regulation functions with high efficiency including arbitrary linear polarization rotation, asymmetric transmission effect, neutral\uffe2\uff80\uff90density\uffe2\uff80\uff90like filter, polarization beam splitter, etc., can be readily realized just by changing the cascaded modules. The physical mechanisms of the versatile polarization controller and chiral metasurface modules are both guaranteed by the Fabry\uffe2\uff80\uff93P\uffc3\uffa9rot\uffe2\uff80\uff90like resonances, which are theoretically verified via the transfer matrix method. It is envisioned that the modular concept will be of great benefit to designing compact multifunctional polarization controllers.Insights into the fascinating molecular world of biological processes are crucial for understanding diseases, developing diagnostics, and effective therapeutics. These processes are complex as they involve interactions between four major classes of biomolecules, i.e., proteins, nucleic acids, carbohydrates, and lipids, which makes it important to be able to discriminate between all these different biomolecular species. In this work, a deep learning\uffe2\uff80\uff90augmented, chemically\uffe2\uff80\uff90specific nanoplasmonic technique that enables such a feat in a label\uffe2\uff80\uff90free manner to not disrupt native processes is presented. The method uses a highly sensitive multiresonant plasmonic metasurface in a microfluidic device, which enhances infrared absorption across a broadband mid\uffe2\uff80\uff90IR spectrum and in water, despite its strongly overlapping absorption bands. The real\uffe2\uff80\uff90time format of the optofluidic method enables the collection of a vast amount of spectrotemporal data, which allows the construction of a deep neural network to discriminate accurately between all major classes of biomolecules. The capabilities of the new method are demonstrated by monitoring of a multistep bioassay containing sucrose\uffe2\uff80\uff90 and nucleotides\uffe2\uff80\uff90loaded liposomes interacting with a small, lipid membrane\uffe2\uff80\uff90perforating peptide. It is envisioned that the presented technology will impact the fields of biology, bioanalytics, and pharmacology from fundamental research and disease diagnostics to drug development.Metasurfaces have emerged as a breakthrough platform for manipulating light at the nanoscale and enabling on\uffe2\uff80\uff90demand optical functionalities for next\uffe2\uff80\uff90generation biosensing, imaging, and light\uffe2\uff80\uff90generating photonic devices.

PVDFs with molar masses up to ca. 8000\uffe2\uff80\uff85g\uffe2\uff80\uff89mol\uffe2\uff88\uff921 and low dispersities (1.11\uffe2\uff80\uff931.49) were obtained. Kinetic experiments revealed that the use of Ir(ppy)3 as photoredox catalyst lead to faster polymerization. A slowdown of the chain equilibration process was observed during the polymerization, attributed to the accumulation of the less reactivatable CF2\uffe2\uff88\uff92CH2\uffe2\uff88\uff92Xa terminated chains.Bacterial cells can biosynthesize palladium nanoparticles (Pd NPs) and utilize those in situ assembled nanoparticles for synergistic bio\uffe2\uff80\uff90abiotic catalysis, which is promising for pollutant remediation. However, such synergistic catalysis is restricted due to the low cell viability and inefficient palladium immobilization.

RESULTS

In this study, conductive and two\uffe2\uff80\uff90dimensional reduced graphene oxide (rGO) was explored for nanocoating of Shewanella oneidensis cells and the construction of a self\uffe2\uff80\uff90assembled Shewanella@rGO bionanohybrid. Impressively, after in situ biosynthesis of Pd NPs on the Shewanella@rGO bionanohybrid, a Shewanella@rGO@Pd bionanohybrid was assembled, which showed about 10 times higher cell viability and 2.4 times more immobilized palladium content than the bionanohybrid without rGO. More importantly, the improved cell viability and enhanced Pd immobilization synergistically promoted Cr(VI) removal using the Shewanella@rGO@Pd bionanohybrid, which was 10 times that of native cells and five times that of the bionanohybrid without rGO.

CONCLUSIONS

This work provides a promising strategy for biosynthesis and in situ assembly of Pd NPs with living bacterial cells, which is promising for synergistic bio\uffe2\uff80\uff90abiotic removal of Cr(VI) and should extend the application of Pd NPs in pollutant remediation. \uffc2\uffa9 2020 Society of Chemical IndustryThis article aims at showing the usefulness of fluoropolymers (FPs), supplying an overview of their synthesis, applications, and recycling. FPs are currently prepared by conventional radical polymerization of fluoromonomers. These specialty polymers, produced in low tonnage compared to that of commodity ones, display outstanding properties, such as chemical, oxidative, and thermal resistances, low refractive index, dissipation factor, permittivity, and water absorptivity, and excellent weatherability and durability. More recent routes for their preparations are suggested, controlled or not, leading to random, alternated, block, graft, dendrimers, or multiarm copolymers, as well as their applications ranging from coatings to high performance (thermoplastic) elastomers, energy related\uffe2\uff80\uff90materials (e.g., fuel cell membranes, components for lithium\uffe2\uff80\uff90ion batteries, electroactive devices, and photovoltaics) to original and surfactants, optical devices, organic electronics, composites, and shape memory polymers.Performance degradation of solid oxide fuel cells due to chromium volatilization is a well\uffe2\uff80\uff90investigated issue in the literature. Therefore, retention coatings were developed to distinctly reduce the chromium volatilization. One approach was by alloying with manganese to ferritic steels to form manganese chromium spinel which is reported to decrease chromium volatilization by 61\uffe2\uff80\uff9375%. In the present paper, the volatilization rates of pure manganese chromium spinel ceramics were examined as well as those of the two oxides forming this spinel\uffe2\uff80\uff94pure chromium oxide and pure manganese oxide\uffe2\uff80\uff94in synthetic air containing 10% water vapor (high p(O2)) and argon/hydrogen containing 10% water vapor (low p(O2)) at 850\uffc2\uffb0C, 950\uffc2\uffb0C, and 1,050\uffc2\uffb0C. Chromium oxide showed higher volatilization rates in high p(O2), whereas manganese oxide demonstrated higher volatilization rates in low p(O2).

Morphological and chemical characterization of the nanocrystals obtained, as well as the main functional properties of the poly(ethylene terephthalate) coated films, showed quite similar characteristics and performances of CNCs obtained from pure cellulose raw material (cotton linters) and the nanoparticles produced from a potential discard of paper making processes (kraft pulp). In particular, the gas barrier properties of the coating produced with CNCs obtained from kraft pulp were very promising, providing oxygen and carbon dioxide permeability values hundreds of times lower than those of equal thickness in comparison with common barrier synthetic polymers, over a broad range of temperatures. The results obtained are relevant not only for the outstanding performances achieved, but also because they evoke a possible positive example of industrial symbiosis in the packaging field, merging together the requirements and needs of the paper and plastic industries and addressing the way towards a better management of waste and materials.

Metal\uffe2\uff80\uff90free carbon electrodes with well\uffe2\uff80\uff90defined composition and smooth topography are prepared via sputter deposition followed by thermal treatment with inert and reactive gases. X\uffe2\uff80\uff90ray photoelectron spectroscopy (XPS) and Raman spectroscopy show that three carbons of similar N/C content that differ in N\uffe2\uff80\uff90site composition are thus prepared: an electrode consisting of almost exclusively graphitic\uffe2\uff80\uff90N (NG), an electrode with predominantly pyridinic\uffe2\uff80\uff90N (NP), and one with \uffe2\uff89\uff881:1 NG:NP composition.

Results show that selectivity toward 4e\uffe2\uff80\uff90reduction of O2 is strongly influenced by the NG/NP site composition, with the material possessing nearly uniform NG/NP composition being the only one yielding a 4e\uffe2\uff80\uff90reduction.

The contamination by chlorinated organic solvents is a worldwide problem as they can deeply penetrate aquifers, accumulating in the sub-surface as lenses of highly hazardous pollutants. In recent years, so called in situ oxidation processes have been developed to remediate chlorinated organic solvents from groundwater and soil by injecting solutions of oxidising agents such as permanganate or peroxydisulphate. We here present modified layered double hydroxides (LDHs) with intercalated oxidising agents that might serve as new reactants for these remediation strategies. LDHs might serve as support and stabiliser materials for selected oxidising agents during injection, as the uncontrolled reaction and consumption might be inhibited, and guarantee that the selected oxidants persist in the subsurface after injection. In this study, LDHs with hydrotalcite- and hydrocalumite-like structures intercalated with permanganate and peroxydisulphate anions were synthesised and their efficiency was tested in batch experiments using trichloroethene or 1,1,2-trichloroethane as the target contaminants. All samples were characterised using powder X-ray diffraction, thermal analysis coupled with mass spectrometry to directly analyse evolving gases, and Fourier-transform infrared spectroscopy. Additionally, particle size distribution measurements were carried out on the synthesised materials. Results of the batch experiments confirmed the hypothesis that oxidising agents keep their properties after intercalation. Permanganate intercalated LDHs proved to be most efficient at degrading trichloroethene while peroxydisulphate intercalated Ca,Al-LDHs were the most promising studied reactants degrading 1,1,2-trichloroethane. The detection of dichloroethene as well as the transformation of the studied reactants into new LDH phases confirmed the successful degradation of the target contaminant by oxidation processes generated from the intercalated oxidising agent.

Single bubble dynamics are of fundamental importance for understanding the underlying mechanisms in liquid\uffe2\uff80\uff93vapor transition phenomenon known as cavitation. In the past years, numerous studies were published and results were extrapolated from one technique to another and further on to \uffe2\uff80\uff9creal-world\uffe2\uff80\uff9d cavitation. In the present paper, we highlight the issues of using various experimental approaches to study the cavitation bubble phenomenon and its effects. We scrutinize the transients bubble generation mechanisms behind tension-based and energy deposition-based techniques and overview the physics behind the bubble production. Four vapor bubble generation methods, which are most commonly used in single bubble research, are directly compared in this study: the pulsed laser technique, a high- and low-voltage spark discharge and the tube arrest method. Important modifications to the experimental techniques are implemented, demonstrating improvement of the bubble production range, control and repeatability. Results are compared to other similar techniques from the literature, and an extensive report on the topic is given in the scope of this work. Simple-to-implement techniques are presented and categorized herein, in order to help with future experimental design. Repeatability and sphericity of the produced bubbles are examined, as well as a comprehensive overview on the subject, listing the bubble production range and highlighting the attributes and limitation for the transient cavitation bubble techniques.

This paper aims at investigating the potential of vine shoots (ViSh) upcycling as fillers in novel poly(3-hydroxybutyrate-3-hydroxyvalerate) (PHBV) based biocomposites. ViSh particles of around 50\uffc2\uffa0\uffc2\uffb5m (apparent median diameter) were obtained combining dry grinding processes, and mixed with PHBV using melt extrusion. Thermal stability and elongation at break of biocomposites were reduced with increasing contents of ViSh particles (10, 20 and 30\uffc2\uffa0wt%), while Young\uffe2\uff80\uff99s modulus and water vapor permeability were increased. It was shown that a surface gas-phase esterification allowed to significantly increase the hydrophobicity of ViSh particles (increase of water contact angles from 59\uffc2\uffb0 to 114\uffc2\uffb0), leading to a reduction of 27% in the water vapor permeability of the biocomposite filled with 30\uffc2\uffa0wt% of ViSh. The overall mechanical performance was not impacted by gas-phase esterification, demonstrating that the interfacial adhesion between the virgin ViSh particles and the PHBV matrix was already good and that such filler surface treatment was not required in that case. It was concluded that ViSh particles can be interestingly used as low cost fillers in PHBV-based biocomposites to decrease the overall cost of materials.

The objective of the present study was to better understand the potential environmental benefit of using vine shoots (ViShs), an agricultural residue, as filler in composite materials. For that purpose, a comparative life cycle assessment (LCA) of a rigid tray made of virgin poly(3-hydroxybutyrate-co-3-hydroxyvalerate) PHBV, polylactic acid (PLA) or polypropylene (PP), and increasing content of ViSh particles was performed. The contribution of each processing step in the life cycle on the different environmental impacts was identified and discussed. Furthermore, the balance between the environmental and the economic benefits of composite trays was discussed.

Methods

This work presents a cradle-to-grave LCA of composite rigid trays. Once collected in vineyards, ViShs were dried and ground using dry fractionation processes, then mixed with a polymer matrix by melt extrusion to produce compounds that were finally injected to obtain rigid trays for food packaging. The density of each component was taken into account in order to compare trays with the same volume. The maximum filler content was set to 30 vol% according to recommendations from literature and industrial data. The ReCiPe 2016 Midpoint Hierarchist (H) methodology was used for the assessment using the cutoff system model.

Results and discussion

This study showed that bioplastics are currently less eco-friendly than PP. This is in part due to the fact that LCA does not account for, in existing tools, effects of microplastic accumulation and that bioplastic technologies are still under development with low tonnage. This study also demonstrated the environmental interest of the development of biocomposites by the incorporation of ViSh particles. The minimal filler content of interest depended on the matrices and the impact categories. Concerning global warming, composite trays had less impact than virgin plastic trays from 5 vol% for PHBV or PLA and from 20 vol% for PP. Concerning PHBV, the only biodegradable polymer in natural conditions in this study, the price and the impact on global warming are reduced by 25% and 20% respectively when 30 vol% of ViSh are added.

Conclusion

The benefit of using vine shoots in composite materials from an environmental and economical point of view was demonstrated. As a recommendation, the polymer production step, which constitutes the most important impact, should be optimized and the maximum filler content in composite materials should be increased.

In spite of the ubiquity and destructiveness of this phenomenon, no fully satisfactory treatment is currently available to arrest and/or prevent bowing. In this study, a treatment based on formation of hydroxyapatite (HAP) was investigated as a possible route to arrest and possibly prevent bowing of Carrara marble slabs. Four different formulations of the HAP treatment were tested and compared to ammonium oxalate and ethyl silicate (widely used in the practice of marble conservation). The treatments were applied onto pre-weathered and unweathered specimens to investigate their ability to arrest and prevent bowing, respectively. Marble behavior was studied in terms of residual strain and bowing after thermal cycles up to 90\u00a0\u00b0C in dry and wet conditions. Marble cohesion was assessed before and after the thermal cycles by ultrasound. The HAP treatments exhibited promising results, as the residual strain and the bowing after the cycles were always lower or equal to the untreated references, while marble cohesion was always higher. Surprisingly, ammonium oxalate caused marked worsening of marble thermal behavior. In the case of ethyl silicate, most of the initial benefit after consolidation was lost after the thermal cycles. In general, the results of the study point out the importance of evaluating marble thermal behavior to assess the suitability of any conservation treatment and suggest that treatments able to strengthen marble without causing excessive pore occlusion and stiffening are preferable to enhance durability to thermal cycles.", "keywords": ["0211 other engineering and technologies", "Calcium oxalate; Hydroxyapatite; Marble; Thermal behavior; Thermal weathering; Warping; Geology", "02 engineering and technology", "ING-IND/22 Scienza e tecnologia dei materiali", "Warping Marble Hydroxyapatite Calcium oxalate Thermal behavior Thermal weathering", "0210 nano-technology"]}, "links": [{"href": "https://cris.unibo.it/bitstream/11585/643027/4/Bowing%20%28EES%29_Copertina.pdf"}, {"href": "http://link.springer.com/content/pdf/10.1007/s12665-018-7547-7.pdf"}, {"href": "https://doi.org/10.1007/s12665-018-7547-7"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Environmental%20Earth%20Sciences", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1007/s12665-018-7547-7", "name": "item", "description": "10.1007/s12665-018-7547-7", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1007/s12665-018-7547-7"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2018-05-01T00:00:00Z"}}, {"id": "10.1007/s40962-016-0099-2", "type": "Feature", "geometry": null, "properties": {"license": "Closed Access", "updated": "2026-04-03T16:15:32Z", "type": "Journal Article", "created": "2016-10-21", "title": "Development of Lead-Free Bronze with Sulfide Dispersion for Sliding Applications", "description": "Cu alloys such as bronze have long been used as bearing materials because of their good run-in properties for steels used as mating materials.

The problem of mycotoxin contamination has been recently aggravated due to the increased complexity of the farm-to-fork chains, resulting in negative effects on human and animal health and, consequently, economics. The easy-to-use, on-site, on-demand, and rapid monitoring of mycotoxins in food/feed is highly desired. In this work, we report on an advanced mycotoxin biosensor based on an array of graphene field-effect transistors integrated on a single silicon chip. A specifically designed aptamer against Ochratoxin A (OTA) was used as a recognition element, where it was covalently attached to graphene surface via pyrenebutanoic acid, succinimidyl ester (PBASE) chemistry. Namely, an electric field stimulation was used to promote more efficient \u03c0-\u03c0 stacking of PBASE to graphene. The specific G-rich aptamer strand suggest its \u03c0-\u03c0 stacking on graphene in free-standing regime and reconfiguration in G-quadruplex during binding an OTA molecule. This realistic behavior of the aptamer is sensitive to the ionic strength of the analyte solution, demonstrating a 10-fold increase in sensitivity at low ionic strengths. The graphene-aptamer sensors reported here demonstrate fast assay with the lowest detection limit of 1.4 pM for OTA within a response time as low as 10 s, which is more than 30 times faster compared to any other reported aptamer-based methods for mycotoxin detection.

However, no significant differences were detected between spontaneous and electrografted layers in their ability to resist protein fouling despite their differences in coverage. Voltammetry studies show that spontaneous grafting has minimal effects on the response of standard redox probes in solution, whereas electrografting results in additional charge transfer impedance arising from increased electrode passivation.

The trends in onset potential were correlated to the carbon nanostructure and chemical composition of the electrodes as determined via Raman spectroscopy and X-ray photoelectron spectroscopy analysis. Results suggest that: 1) the ORR activity in acidic conditions is strongly correlated to the concentration of pyridinic nitrogen sites. 2) At high pH, the presence of graphitic nitrogen sites and a graphitized carbon scaffold are the strongest predictors of high ORR onsets, while pyridinic nitrogen site density does not correlate to ORR activity. An inversion region where pyridine-mediated activity competes with graphitic-N mediated activity is identified in the pH region close to the value of pKa of the pyridinium cation.

Photocatalysis has been regarded as a desirable technology for organic pollutant removal, but is underappreciated in degradation of persistent organic pollutants due to the low adsorption capacity and photocatalytic efficiency of photocatalysts. In this study, a scalable photocatalyst of single/few-layered carbon nitride nanosheets with carbon vacancies (Cv-CNNs) is synthesized through a thermal process. Quantum mechanical simulation results reveal that the C vacancies can change the plane structure of CN sheets, enhancing adsorption capability of Cv-CNNs towards sulfadiazine (SDZ, a refractory antibiotic pollutant). Furthermore, the introduction of C vacancies in Cv-CNNs enhance the redox capacity, promoting photocatalytic hydrogen evolution and SDZ degradation. The removal efficiency of SDZ (5\u202fmg L\u22121) reaches almost 100% within 20\u202fmin under visible-light irradiation. In addition, the photocatalyst delivers a high H2 evolution rate of 2.03\u202fmmol\u202fh\u22121 g\u22121. The study provides a large-scale-production metal-free photocatalyst for practical application in antibiotics removal from wastewater or solar-to-hydrogen energy conversion.", "keywords": ["13.

Conducted research presents a rapid and cost-effective approach to technological processing of screen-printed films with anatase TiO2 nanoparticles, by utilizing the high fluence laser radiation. The influence of laser sintering on the screen-printed films was characterized with optical and scanning electron microscopy, energy-dispersive X-ray (EDX) spectroscopy, Raman spectroscopy, nanoindenter measurements and current vs voltage measurements. Investigation of surface morphology of screen-printed films revealed that higher laser fluences caused significant decrease in film thickness, trough evaporation of organic additives used in the paste matrix. EDX mapping of carbon content in untreated and laser sintered surface confirmed removal of organic additives. Laser sintering stimulated breaking of large agglomerates into much finer nano-sized particles and promoted formation of necking between individual grains. Crystal structure and vibrational properties of anatase TiO2 nanoparticles was monitored with Raman spectroscopy before and after laser sintering. Obtained results point out that anatase polymorph was preserved during the sintering process, without appearance of other phases. From observation of the behavior of the most intense Eg Raman active mode it was deduced that laser sintering provoked a formation of structural defects i.e. oxygen vacancies in TiO2 nanoparticles, whose concentration increased in the samples treated with higher laser fluences. Mechanical properties of untreated and laser sintered samples were investigated with nanoindenter measurements using several load forces, in order to carefully probe the Young modulus and mechanical hardness. From the analysis of collected data, we established that overall improvement of the mechanical properties with laser sintering originates from formation of very dense ceramic layer with enhanced interconnectivity between individual TiO2 nanoparticles. Measurements of current vs voltage characteristics clearly demonstrated that increase in laser fluence leads to drastic increase in current values and improvement of electric conductivity.", "keywords": ["02 engineering and technology", "0210 nano-technology", "01 natural sciences", "0104 chemical sciences"]}, "links": [{"href": "https://doi.org/10.1016/j.ceramint.2018.03.181"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Ceramics%20International", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1016/j.ceramint.2018.03.181", "name": "item", "description": "10.1016/j.ceramint.2018.03.181", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1016/j.ceramint.2018.03.181"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2018-06-01T00:00:00Z"}}, {"id": "10.1016/j.chemosphere.2017.07.035", "type": "Feature", "geometry": null, "properties": {"updated": "2026-04-03T16:16:23Z", "type": "Journal Article", "created": "2017-07-08", "title": "Assessment and prediction of joint algal toxicity of binary mixtures of graphene and ionic liquids", "description": "Graphene and ionic liquids (ILs) released into the environment will interact with each other. So far however, the risks associated with the concurrent exposure of biota to graphene and ILs in the environment have received little attention. The research reported here focused on observing and predicting the joint toxicity effects in the green alga Scenedesmus obliquus exposed to binary mixtures of intrinsic graphene (iG)/graphene oxide (GO) and five ILs of varying anionic and cationic types. The isolated ILs in the binary mixtures were the main contributors to toxicity. The binary GO-IL mixtures resulted in more severe joint toxicity than the binary iG-IL mixtures, irrespective of mixture ratios. The mechanism of the joint toxicity may be associated with the adsorption capability of the graphenes for the ILs, the dispersion stability of the graphenes in aquatic media, and modulation of the binary mixtures-induced oxidative stress. A toxic unit assessment showed that the graphene and IL toxicities were additive at low concentration of the mixtures but antagonistic at high concentration of the mixtures. Predictions made using the concentration addition and independent action models were close to the observed joint toxicities regardless of mixture types and mixture ratios. These findings provide new insights that are of use in the risk assessment of mixtures of engineered nanoparticles and other environmentally relevant contaminants.", "keywords": ["Anions", "Chlorophyta", "13.

The removal characteristics and mechanisms were also investigated. Results showed that modified sweet potato pectin exhibited greater adsorption performances for Pb2+ than that of natural ones, and showed excellent eco-friendly properties and good potential for adsorption of some other heavy metals (such as Cu2+). The adsorption curves were much more conformed to Langmuir model, and the highest capacity for Pb2+ adsorption was 263.15\u00a0mg/g with 1.00% pectin at pH 7. Chemical adsorption process of pectin for Pb2+ absorption involved O-containing functional groups (O-H, COO-), cation exchange, and along with electrostatic interactions.
