Upcycling waste polyethylene terephthalate (PET) bottles into high-performance activated carbon for electrochemical desalination

Upcycling waste polyethylene terephthalate (PET) bottles has attracted intensive research interests. This simultaneously alleviates plastic pollution and achieves a waste-to-resource strategy. Waste PET water bottles were used to fabricate value-added activated carbon (AC) electrodes for capacitive deionization (CDI). The KOH activation temperature (greater than 700 °C) prominently affected the physi-chemical properties and desalination performance of PET-derived activated carbons (PET-AC). Profiting from a large Brunauer–Emmet–Teller specific surface area (1448 m2 g−1) with a good mesoporous structure (the ratio of the mesopore volume to the total pore volume was 41.3%), PET-AC-1000 (activated at 1000 °C) possessed a huge specific capacitance of 108 F g−1 for capacitive ion storage. Moreover, when utilized as the electrode material in single-pass CDI, PET-AC-1000 exhibited a maximum electrosorption capacity of 10.82 ± 0.11 mg g−1 and a low level of energy consumption (0.07 kWh mol−1), associated with good electrochemical charging-discharging cyclic stability. The results provide a promising facile approach to tackle the challenge of plastic pollution and promote the advancement of electrode materials for economic affordable and energy-efficient electrochemical desalination process, which meets the United Nations (UN) sustainable development goals (SDGs).

Performance and environmental impact of ethanol-kerosene blends as sustainable aviation fuels in micro turbo-engines

The research experimentally examines the viability of ethanol (E) as a sustainable aviation fuel (SAF) when mixed with kerosene (Ke) – Jet A aviation fuel + 5% Aeroshell oil. Various blends of ethanol and kerosene (10%, 20%, and 30% vol. of ethanol added in kerosene) were subjected to testing in an aviation micro turbo-engine under different operational states: idle, cruise, and maximum power. During the tests, monitoring of engine parameters such as burning temperature, fuel consumption, and thrust force was conducted. The study also encompassed the calculation of crucial performance indicators like burning efficiency, thermal efficiency, and specific consumption for all fuel blends under maximum power conditions. Physical-chemical properties of the blends, encompassing density, viscosity, flash point, and calorific power, were determined. Furthermore, elemental analysis and FTIR were used for chemical composition determination. The research delved into analyzing the air requirements for stoichiometric combustion and computed resulting emissions of CO2 and H2O. Experimental assessments were performed on the Jet Cat P80® micro-turbo engine, covering aspects such as starting procedures, acceleration, deceleration, and emissions of pollutants (CO and SO2) during diverse engine operational phases. The outcomes reveal that the examined fuel blends exhibited stable engine performance across all tested conditions. This indicates that these blends hold promise as sustainable aviation fuels for micro turbo-engines, presenting benefits in terms of diminished pollution and a more ecologically sound raw material base for fuel production.

SrNiO3 perovskite/CeO2 composites as heterogeneous photocatalysts for the 2-propanol oxidation in gas–solid regime

Both SrNiO3 perovskite and CeO2 are materials suitable for photocatalytic purposes. In this work, the preparation and physicochemical characterization of bare SrNiO3 and CeO2 along with composites where CeO2 was enriched with the perovskite from 15 to 70 % in mass of SrNiO3 in the composite are described. The materials have been used for the photocatalytic oxidation of 2-propanol in gas–solid regime in the presence of UV-LED or simulated solar irradiation. The solids were characterized by XRD, SEM/EDX, N2 adsorption/desorption and FTIR and UV–Vis diffuse reflectance spectroscopies. The composite containing 15 % w/w of SrNiO3 and 85 % w/w of CeO2 resulted the most active, giving rise the complete degradation of 2-propanol after 1.5 h or 6.0 h of irradiation by UV-LED and simulated solar light irradiation, respectively. Photocatalytic activity results are discussed considering the physical–chemical properties on the catalysts.

A Framework for Developing Tools to Predict PFAS Physical–Chemical Properties and Mass-Partitioning Parameters

A framework for developing predictive models for PFAS physical–chemical properties and mass-partitioning parameters is presented. The framework is based on the objective of developing tools that are of sufficient simplicity to be used rapidly and routinely for initial site investigations and risk assessments. This is accomplished by the use of bespoke PFAS-specific QSPR models. The development of these models entails aggregation and curation of measured data sets for a target property or parameter, supplemented by estimates produced with quantum–chemical ab initio predictions. The application of bespoke QSPR models for PFAS is illustrated with several examples, including partitioning to different interfaces, uptake by several fish species, and partitioning to four different biological materials. Reasonable correlations to molar volume were observed for all systems. One notable observation is that the slopes of all of the regression functions are similar. This suggests that the partitioning processes in all of these systems are to some degree mediated by the same mechanism, namely hydrophobic interaction. Special factors and elements requiring consideration in the development of predictive models are discussed, including differences in bulk-phase versus interface partitioning processes.

Functionalization methods for ZnO nanoparticles with citric acid and their effect on the antimicrobial activity

The functionalization of ZnO nanoparticles has proven to be an effective alternative to avoid agglomeration and improve their physic-chemical properties. In this work, we studied the functionalization of ZnO nanoparticles using citric acid (CA) through two methods: in situ functionalization and sonochemical functionalization to compare the effects on the physicochemical and antimicrobial properties of functionalized commercial ZnO nanoparticles with those synthesized and functionalized at the same time. Both methods are considered environmentally friendly (green chemistry) since the use of chemical toxic agents was avoided and the reaction medium was water. The in situ method demonstrated the ability of CA to act as a reducing and stabilizing agent. Fourier transform infrared spectroscopy (FTIR) and RAMAN spectroscopy analyses confirmed the functionality of ZnO nanoparticles, through the formation of the COO−/ZnO complex. The wurtzite-type hexagonal crystalline structure of the ZnO nanoparticles was confirmed by X-ray diffraction (XRD). The thermogravimetric analysis (TGA) analysis showed that in situ functionalization was more favored than sonochemical functionalization since 46.66 % and 27.22 % of the organic ligand were obtained on the surface of the nanoparticles, respectively. X-ray photoelectron spectroscopy (XPS) results revealed the chemical and electronic state of the zinc which was 2+ and atomic percentages of carbon of 40.64 % and 38.35 %, as well as atomic percentages of oxygen of 38.67 and 36.78 % for ZnO-AC and ZnO-AC-R1 nanoparticles, respectively. The evaluation of the antibacterial efficiency of the nanoparticles functionalized by both methods demonstrated that they possess a superior antimicrobial activity when compared with non-fuctionalized nanoparticles. The ZnO nanoparticles synthesized and functionalized via in situ showed an efficiency of 99.99 % starting concentrations of 200 ppm.

Genome-wide identification and characterization of SNW/SKIP domain-containing proteins in plants.

Sessile organisms, such as plants, developed various ways to sense and respond to external and internal stimuli to maximize their fitness through evolutionary time. Transcripts and protein regulation are, among many, the main mechanisms that plants use to respond to environmental changes. SKIP protein is one such, presenting an SNKW interacting domain, which is highly conserved among eukaryotes, where SKI interacting protein acts in regulating key processes. In the present work, many bioinformatics tools, such as phylogenetic relationships, gene structure, physical-chemical properties, conserved motifs, prediction of regulatory cis-elements, chromosomal localization, and protein-protein interaction network, were used to better understand the genome-wide SNW/SKIP domain-containing proteins. In total, 28 proteins containing the SNW/SKIP domain were identified in different plant species, including plants of agronomic interest. Two main protein clusters were formed in phylogenetic analysis, and gene structure analysis revealed that, in general, the coding region had no introns. Also, expression of these genes is possibly induced by abiotic stress stimuli. Primary structure analysis of the proteins revealed the existence of an evolutionarily conserved functional unit. But physicochemical properties show that proteins containing the SNW/SKIP domain are commonly unstable under in vivo conditions. In addition, the protein network, demonstrated that SKIP homologues could act by modulating plant fitness through gene expression regulation at the transcriptional and post-transcriptional levels. This could be corroborated by the expression number of gene copies of SKIP proteins in many species, highlighting it's crucial role in plant development and tolerance through the course of evolution.

Diagnostic potential of blood plasma longitudinal viscosity measured using Brillouin light scattering

Blood plasma viscosity (PV) is an established biomarker for numerous diseases. Measurement of the shear PV using conventional rheological techniques is, however, time consuming and requires significant plasma volumes. Here, we show that Brillouin light scattering (BLS) and angle-resolved spectroscopy measurements of the longitudinal PV from microliter-sized plasma volumes can serve as a proxy for the shear PV measured using conventional viscometers. This is not trivial given the distinct frequency regime probed and the longitudinal viscosity, a combination of the shear and bulk viscosity, representing a unique material property on account of the latter. We demonstrate this for plasma from healthy persons and patients suffering from different severities of COVID-19 (CoV), which has been associated with an increased shear PV. We further show that the additional information contained in the BLS-measured effective longitudinal PV and its temperature scaling can provide unique insight into the chemical constituents and physical properties of plasma that can be of diagnostic value. In particular, we find that changes in the effective longitudinal viscosity are consistent with an increased suspension concentration in CoV patient samples at elevated temperatures that is correlated with disease severity and progression. This is supported by results from rapid BLS spatial-mapping, angle-resolved BLS measurements, changes in the elastic scattering, and anomalies in the temperature scaling of the shear viscosity. Finally, we introduce a compact BLS probe to rapidly perform measurements in plastic transport tubes. Our results open a broad avenue for PV diagnostics based on the high-frequency effective longitudinal PV and show that BLS can provide a means for its implementation.

Experimental study on selected properties and microstructure of pine-based wood ceramics

Abstract Wood ceramics using biomass materials as templates possess the benefits of facile fabrication and versatile applicability. To investigate the physical properties, chemical properties and microstructure of wood ceramics prepared from biomass materials, the basic properties and potential applications of wood ceramics were expounded. In this paper, wood powder wood ceramics (WPWC) and wood fiber wood ceramics (WFWC) were prepared through the vacuum carbonization method, utilizing pine powder and pine fiber as raw materials. The impact of phenolic resin concentration and mixture filling mass on various properties of wood ceramics, including mass loss rate (MLR), volume shrinkage rate (VSR), apparent porosity (AP), and bending strength (BS) were investigated on this basis. The microtopography and pore structure of wood ceramics were also analyzed. The test results show that an increase in the concentration of phenolic resin led to a decrease in the MLR, VSR, and AP of WPWC and WFWC, while their BS exhibited an increase. When the concentration of phenolic resin was 60 %, the phenolic resin yielded a BS of 8.70 MPa and 9.20 MPa for WPWC and WFWC, respectively. Furthermore, the microstructures of both WPFC and WFWC reveal hierarchical porous structures. The difference is that WPFC has a dispersed three-dimensional network topology in its overall morphology, which is mainly formed by filamentous or long linear glass carbon in wood ceramics dominated by carbon. The natural and consistent pore structure of WFWC is comparable to a three-dimensional honeycomb structure, the primary mesoporous size was around 40.28 nm and the main macropore size was more than 10,000 nm. It elucidates the pore structure of WPWC and WFWC, characterized by “hierarchical porosity”, the differences and relationships between porous wood ceramics derived from powdery and fibrous biomass as raw materials were analyzed, which contributes to the advancement of the fundamental principles of wood ceramics and establishes a theoretical basis for the practical exploration and development of biomass materials.

CUGAS2 КРИСТАЛЛДАРЫ, АЛАРДЫН МҮНӨЗДӨМӨЛӨРҮ ЖАНА ИШТЕТИЛИШИ

In this article, the characteristics of CuGaS2 crystals grown are studied by the gas transport method and the two-temperature synthesis method. The described materials, primarily original ones, as well as the presented materials, allow us to conclude that a wide range of compounds represents an unexplored class of substances, especially in the field of experimental determination of their physic-chemical properties, methods of crystal growth and correlation of material characteristics with technological parameters of the production processes. The growing practical application of semiconductors stimulates research into new materials. In recent years, much attention has been paid to studying the physical properties of multicomponent systems, especially crystals of groups I-II-VI2, which are promising for many technical applications. For a number of crystals of group I-II-VI2, methods for selecting p- and n-type samples have been developed, on the basis of which heterojunctions have been created.

The composition and structure of plant fibers affect their fining performance in wines

In recent years, the wine industry has shifted towards plant-based fining agents for food safety reasons and consumer preferences. This study analysed the interaction of five plant fibers with red wine phenolic compounds to determinate their performance as fining agents. Chemical composition, polysaccharide profile, and physical properties were examined. Pea, cellulose, and Sauvignon Blanc pomace fibers effectively reduced tannin content while minimally affecting the concentration of anthocyanins, flavonols and wine color. Contrary to previous beliefs, the presence of pectins in fibers didn't play a crucial role in phenolic compound interaction since cellulose-rich fibers with low pectin concentration also bound tannins effectively, especially those with small particle size and high contact surface. Pea fiber, rich in cellulose and pectins, showed remarkable tannin retention while minimally affecting wine color. This research highlights the potential of plant fibers as effective fining agents in wine production and how their composition affects their performance.

Rational Use of Waste from Oil Extraction Production — Bleaching Clay Waste

The results of studies of the physic-chemical and sorption properties of bleaching clay waste, the prospects for its use for the purification of polluted waters, as well as the possibility of subsequent disposal of used materials are presented. Using the method of low-temperature nitrogen adsorption-desorption, it was found that the studied bleaching clay waste has a specific surface area of 185.53 m2/g and has a mesoporous structure. The sorption properties of clay waste were studied and it was found that at a dosage of 1.5 g/dm3, the purification efficiency of the standard solutions containing Cu2+ ions with a concentration of 10 mg/dm3 is 96.7 %. It has been found that the maximum sorption capacity, determined under static conditions for clay fired at a temperature of 350 °C, is 0.41 mmol/g. The use of bleaching clay as filler pigments in the manufacture of paints and varnishes has been proposed and demonstrated.

Mesoporous Silica with an Alveolar Construction Obtained by Eco-Friendly Treatment of Rice Husks.

The high silicon content in rice plant waste, specifically rice husks, makes this waste by-product attractive for the extraction and valorization of silicon oxide, which is widely used as an inert support in catalysis, drug delivery and molecular sieving. The procedures currently used for the treatment of plant biomass make extensive use of mineral acids (HCl, H2SO4, HNO3), which, besides them being potential environmental pollutants, reduce the yield and worsen the chemical-physical properties of the product. In this study, an evaluation of the easy treatment of rice husks by benchmarking different, more eco-friendly carboxylic acids in order to obtain a mesoporous SiO2 with an alveolar structure and a relatively high surface area and pore volume (300-420 m2/g, 0.37-0.46 cm3/g) is presented. The obtained mesoporous silicas are characterized by worm-like pores with a narrow size distribution and a maximum in the range of 3.4-3.5 nm. The mesoporous structure of the obtained materials was also confirmed by TEM. The complete removal of the organic part of the rice husks in the final materials was evidenced by thermogravimetric analysis. The high purity of the obtained mesoporous silica was detected using ICP analysis (98.8 wt. %). The structure peculiarities of the obtained mesoporous silicas were also characterized by solid-state NMR and ATR-FTIR spectroscopies. The morphology of the mesoporous silica was investigated by SEM.

Enhancing agricultural sustainability through CNN-LSTM based land suitability assessment for improved production

Agricultural sustainability is an important concern facing global population expansion and environmental challenges. Accurate land suitability evaluation is critical for ensuring efficient and effective land usage. The aim of this research is to assess the following framework that the Food and Agriculture Organization (FAO) developed, if the land in India is suitable for two key crops, namely maize and barley. Soil specimens and physical-chemical properties from 105 genetic soil profile layers are collected. Weather and landscape data were gathered. Deep learning (DL) techniques were used to map the two crops' land suitability classifications after computation. This study suggests a unique method for assessing land potential for increased agricultural output by Convolution Neural Networks-Long Short-Term Memory (CNN-LSTM) networks. The maps generated by the two ways showed significant disparities. Studies on rain-fed corn, for example, showed that DL-based land suitability maps were more accurate than those created using the traditional method. The outcomes demonstrated that when contrasting the CNN-LSTM method with the conventional methodology, the areas with classes C2 were higher and the areas with categories C1 were less projected. Rainfall during the flowering period, steep slopes, poor soil depth, high pH and a high gravel component were the research area's main drawbacks. Land development activities are recommended to boost productivity and build a sustainable agricultural system. This research contributes to balance farm expansion and environmental protection, supporting a sustainable and resilient agricultural system to fulfill the requirements of the world's rising population.

Purification of yttrium metal by plasma arc melting

Yttrium possesses unique physical-chemical properties and electronic structure, making high purity yttrium metal highly coveted for various applications. Nevertheless, the application of commercial yttrium metal is seriously restricted by the relatively low purity level. Considering the direct purification of commercial yttrium metal, plasma arc melting for decreasing impurity content is proposed. The purification of yttrium metal has been characterized and assessed by 68 impure elements. Experimental results show that plasma arc melting effectively removes impurities, resulting in an increase in the absolute purity of yttrium metal from 97.39 wt % to 99.10 wt %, with a reduction in the presence of 38 impure elements. The vapor pressure, metal separation factor, and mean free path of metallic impurities were calculated and categorized into high volatility, medial volatility, low volatility groups under the experimental conditions. Furthermore, plasma arc melting exhibits significant efficiency in removing nonmetallic impurities, and purification principle and migration mechanism are discussed in this work．The investigation of plasma arc melting proposes a new research direction for the preparation of high purity yttrium, and will promote the application of high purity yttrium in metal materials.

Hyaluronic Acid-Based Nanoparticles Loaded with Rutin as Vasculo-Protective Tools against Anthracycline-Induced Endothelial Damages.

Anthracycline-based therapies exert endothelial damages through peroxidation and the production of proinflammatory cytokines, resulting in a high risk of cardiovascular complications in cancer patients. Hyaluronic acid-based hybrid nanoparticles (LicpHA) are effective pharmacological tools that can target endothelial cells and deliver drugs or nutraceuticals. This study aimed to prepared and characterized a novel LicpHA loaded with Rutin (LicpHA Rutin), a flavonoid with high antioxidant and anti-inflammatory properties, to protect endothelial cells against epirubicin-mediated endothelial damages. LicpHA Rutin was prepared using phosphatidylcholine, cholesterol, poloxamers, and hyaluronic acid by a modified nanoprecipitation technique. The chemical-physical characterization of the nanoparticles was carried out (size, zeta potential, morphology, stability, thermal analysis, and encapsulation efficiency). Cytotoxicity studies were performed in human endothelial cells exposed to epirubicin alone or in combination with Free-Rutin or LicpHA Rutin. Anti-inflammatory studies were performed through the intracellular quantification of NLRP-3, MyD-88, IL-1β, IL-6, IL17-α, TNF-α, IL-10, and IL-4 using selective ELISA methods. Morphological studies via TEM and image analysis highlighted a heterogeneous population of LicpHA particles with non-spherical shapes (circularity equal to 0.78 ± 0.14), and the particle size was slightly affected by Rutin entrapment (the mean diameter varied from 179 ± 4 nm to 209 ± 4 nm). Thermal analysis and zeta potential analyses confirmed the influence of Rutin on the chemical-physical properties of LicpHA Rutin, mainly indicated by the decrease in the surface negative charge (from -35 ± 1 mV to -30 ± 0.5 mV). Cellular studies demonstrated that LicpHA Rutin significantly reduced cell death and inflammation when compared to epirubicin alone. The levels of intracellular NLRP3, Myd-88, and proinflammatory cytokines were significantly lower in epirubicin + LicpHA Rutin-exposed cells when compared to epirubicin groups (p < 0.001). Hyaluronic acid-based nanoparticles loaded with Rutin exerts significant vasculo-protective properties during exposure to anthracyclines. The overall picture of this study pushes towards preclinical and clinical studies in models of anthracycline-induced vascular damages.

Tribological properties of the beetle leg joints

Tribological properties of femoro-tibial leg joints in two beetles, darkling beetle Zophobas morio and Congo rose chafer Pachnoda marginata were studied. Very low friction of 0.004 was revealed by the direct measurements in the joint. It is assumed that semi-solid lubricant functioning as in technical bearings is one of the leading factors of the friction minimization. Dependence of the surface texture and physical chemical properties (hydrophobicity) on the cuticle friction was analysed. Contribution of the surface texture to the tribological properties of contacting surfaces was examined by the measurement in the tribosystem “contacting surface/glass”. It is supposed that coefficient of friction (COF) decreases with decrease of surface roughness. At the same time, no statistically significant correlation was found between the hydrophobicity of the surface and the value of the friction coefficient.

Nature of Metal‐Metal Bond in Group‐V Dinuclear Metallaborane Compounds: Open‐Shell – Open‐Shell Vs Closed‐Shell – Closed‐Shell Interaction

The investigation of metal‐metal bonding is interesting due to the captivating structural features, unique chemical reactivity and physical properties of this class of complexes. The bonding situation in the metallaboranes [(Cp*)2M2(B2H6)2] of group‐V elements (M) in the +3 oxidation state [M = V (1), Ta (2)] was investigated by the DFT, NBO, QTAIM calculations and further with Energy Decomposition Analyses coupled with Natural Orbital for Chemical Valence (EDA‐NOCV). Even though the metallaboranes are isostructural, the nature of metal‐metal bonding interaction was found to be different, showing open‐shell ‐ open‐shell interaction for vanadium while closed‐shell – closed‐shell interaction between two tantalum atoms. The EDA‐NOCV analyses suggest that TaIII‐TaIII bonding interactions are stronger than those of divanadaborane analogue, having an intrinsic interaction energy of ‐247.6 kcal/mol (2), and the V‐V bond has an interaction energy of ‐192.5 kcal/mol (1). The analyses indicate that the strength of the metal‐metal bond becomes stronger as the metal becomes heavier. This is due to the higher contribution from electrostatic stabilization energy. The pairwise orbital analysis of the metal‐metal bond denotes significant dative‐interaction between two tantalum metals, contributing 52.6% (2) to total orbital interaction energy. The electron‐sharing interaction energy has been computed to be 44.3% for 1.

STUDYING THE INFLUENCE OF ALKALINE TREATMENT AND MODIFICATION OF ZEOLITE ON ITS PHYSICAL-CHEMICAL AND CATALYTIC PROPERTIES IN THE PROCESS OF PROPANE CONVERSION TO OLEFIN HYDROCARBONS

In this work, the effect of alkaline treatment of ZSM-5 zeolite with a modulus of 100 on its physicochemical properties and activity in the process of converting propane into olefin hydrocarbons was investigated. The growing demand for lower olefins is driving the search for new ways to improve existing technologies and develop new, more efficient catalysts. Catalytic dehydrogenation of light alkanes is an alternative to the petrochemical method for producing lower olefins from cheap and available gas and oil and gas feedstocks. At the same time, dehydrogenation reactions of light alkanes have a number of features and limitations that determine the range of possible catalysts. Zeolites are a class of supports that, due to their large surface area, nanometer-sized pores, and good thermal stability, can be used to prepare catalysts for the dehydrogenation of C2−C4 alkanes. An important feature of crystalline high-silica zeolites is the ability to change their acidic properties under the influence of various pre-treatments, which opens up great opportunities for their regulation and, accordingly, the selection of the most effective catalyst for a particular chemical process. It has been shown that alkaline treatment of zeolite leads to the formation of an additional amount of mesopores, which, in turn, affects its catalytic properties in the process of converting propane into olefinic hydrocarbons. The dependence of the activity and selectivity of the zeolite catalyst on the concentration of the alkali solution used for its treatment has been established. It was found that treatment of the zeolite catalyst with a 1.0 M NaOH solution leads to an increase in its selectivity with respect to the formation of C2–C4 olefins from propane, which at a process temperature of 650 °C reaches 32.0% with a propane conversion of 81%. It has been shown that additional promotion of desilicated zeolite with magnesium or manganese increases its activity with respect to the formation of olefinic hydrocarbons from propane.

Bioactive Hydrogel Formulation Based on Ferulic Acid-Grafted Nano-Chitosan and Bacterial Nanocellulose Enriched with Selenium Nanoparticles from Kombucha Fermentation.

Selenium nanoparticles (SeNPs) have specific properties that result from their biosynthesis particularities. Chitosan can prevent pathogenic biofilm development. A wide palette of bacterial nanocellulose (BNC) biological and physical-chemical properties are known. The aim of this study was to develop a hydrogel formulation (SeBNCSFa) based on ferulic acid-grafted chitosan and bacterial nanocellulose (BNC) enriched with SeNPs from Kombucha fermentation (SeNPsK), which could be used as an adjuvant for oral implant integration and other applications. The grafted chitosan and SeBNCSFa were characterized by biochemical and physical-chemical methods. The cell viability and proliferation of HGF-1 gingival fibroblasts were investigated, as well as their in vitro antioxidant activity. The inflammatory response was determined by enzyme-linked immunosorbent assay (ELISA) of the proinflammatory mediators (IL-6, TNF-α, and IL-1β) in cell culture medium. Likewise, the amount of nitric oxide released was measured by the Griess reaction. The antimicrobial activity was also investigated. The grafting degree with ferulic acid was approximately 1.780 ± 0.07% of the total chitosan monomeric units, assuming single-site grafting per monomer. Fourier-transform infrared spectroscopy evidenced a convolution of BNC and grafted chitosan spectra, and X-ray diffraction analysis highlighted an amorphous rearrangement of the diffraction patterns, suggesting multiple interactions. The hydrogel showed a high degree of cytocompatibility, and enhanced antioxidant, anti-inflammatory, and antimicrobial potentials.
