Summary: Wound dressings with poor antibacterial properties, adhesion to the wound site, weak mechanical strength, and lack of porosity and flexibility lead to blood loss, delayed wound repair, and sometimes death. In this study, a multifunctional graphene-based nanobiocomposite wound dressing was developed, which demonstrated hydrophilic properties, good mechanical strength, antibacterial activity, non-toxicity to cells, and pro-angiogenic potential. In in-vivo studies using a rat model, the nanobiocomposite dressing significantly enhanced wound healing compared to commercially available dressings, achieving complete wound closure in 14 days. Overall, the CGAPL nanobiocomposite dressing offers a novel and efficient solution for faster wound healing.

Summary: In this study, effective Gemini cationic surfactants (CSII, CSIV) were synthesized and characterized. The adsorptive properties of CSII and CSIV at HCl/air and C-steel/HCl interfaces were investigated using surface tension and electrochemical parameters. The results showed that CSII and CSIV have high adsorption affinity at the HCl/air interface, with aliphatic chains promoting surfactant adsorption. Electrochemical impedance spectroscopy and potentiodynamic polarization revealed that CSII and CSIV act as mixed inhibitors, significantly enhancing the charge transfer resistance of C-steel in HCl. Theoretical calculations and simulations supported the experimental findings, demonstrating the relationship between corrosion inhibition and molecular structure.

Summary: In this study, flower-shaped MoS2/graphene heterostructures were used as electrode materials on flexible substrates to overcome the limitations of low energy density and poor durability of MoS2. The results showed exceptional capacitance of 853 F g(-1) at 1.0 A g(-1) in three-electrode measurements, and 208 F g(-1) at 0.5 A g(-1) with long-term cyclic durability in asymmetric supercapacitor measurements. Nearly 86.5% of the electrochemical capacitance was retained after 10,000 cycles at 0.5 A g(-1). Moreover, a remarkable energy density of 65 Wh kg(-1) at a power density of 0.33 kW kg(-1) was obtained. The MoS2/Gr heterostructure composites have great potential for the development of advanced energy storage devices.

Summary: This study presents the performance and durability of protonic ceramic fuel cells (PCFCs) in an ammonia fuel injection environment. The use of a palladium (Pd) catalyst improves the low ammonia decomposition rate in PCFCs with lower operating temperatures. By treating the anode with Pd catalyst, the performance of PCFCs is significantly enhanced, with a peak power density of 340 mW cm (-2) at 500 degrees C. The Pd catalysts are deposited through an atomic layer deposition post-treatment process, improving current collection and reducing polarization resistance in the low-temperature region.

Summary: The synthesis and structure configuration of bis ethoxylated cationic surfactant (BOECS) were verified using a variety of techniques. BOECS exhibited excellent corrosion resistance and inhibition of sulfate reducing bacteria growth. The adsorption affinity of BOECS at the air/water interface and its critical micelle concentration (CMC) were determined by its physical properties. The electrochemical kinetic parameters showed that BOECS is a mixed-type inhibitor with high inhibition efficacy against HCl and H2SO4. Calculated adsorption energy change (ΔGads) and theoretical adsorption energy (Eads) values indicated strong and spontaneous adsorption of BOECS. The synthesized BOECS also demonstrated potent inhibitory potential against sulfate reducing bacteria, significantly reducing their growth.

Summary: In this study, a digital colorimetric sensor platform is shown to convert a conventional energy system, like gas-insulated switchgear (GIS), into a smart green energy system. The sensor platform includes a colorimetric sensor film (CSF), an array of silicon photodiodes, and a low-power-driven fiber optical photodiode with wireless communication. The photodiode measures the transmitted light of the color-variable CSF when exposed to sulfur dioxide (SO2) gas, a decomposition by-product of sulfur hexafluoride (SF6) gas in GIS. The electrical photocurrent measurement through the CSF is reported to be able to remotely and in real-time monitor the concentration of SO2 gas, showing comparable behavior to UV-Vis absorption measurement. The sensor has a detection limit of 0.78 ppm, sufficient for analyzing GIS insulation deterioration for green energy systems.

Summary: This study investigated the use of hollow perovskite architectures to enhance the photostability of mixed halide wide-bandgap perovskites. By analyzing the properties of hollow perovskite thin films, it was found that the incorporation of hollow structures improved photostability compared to non-hollow samples. The inclusion of enI(2) further reduced ionic conductivity and trap density. While the initial efficiency of solar cells decreased with increasing enI2 concentration, the open-circuit voltage value increased, potentially due to the enhancement of the band gap. Overall, hollow perovskite architectures show great potential in enhancing the photostability of mixed halide perovskites.

The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
