Summary: A new one-step strategy was developed to maximize the adhesion of graphene oxide (GO) particles to the surface of polyvinylidene fluoride (PVDF) nanofibers, achieving efficient adsorption of heavy metal ions. The as-prepared fiber surface had a maximized GO load, with an adsorption capacity for Cr(VI) of 271 mg/g and a 99% removal rate achieved within 2 hours. After multiple adsorption-desorption tests, the adsorption removal efficiency remained above 80%.

Summary: Polypyrrole-based adsorbents have shown great potential in removing Cr(VI) from wastewater. However, the simultaneous removal of metal cations remains a challenge. In this study, a novel EDTA-crosslinking-chitosan/polypyrrole composite was developed, which exhibited high adsorption capacities for Cr(VI) anions and other metal cations. The adsorption mechanism involved reduction, chelation, electrostatic attraction, and ion exchange. Furthermore, the adsorbent maintained stability after multiple adsorption-desorption cycles.

Summary: In this study, a bilayered asymmetric nanofibrous membrane was prepared, with a hydrophilic chitosan/chitosan oligosaccharide (COS) nanofibrous membrane as the bottom layer and a hydrophobic polycaprolactone (PCL) nanofibrous membrane as the top layer. Results showed that incorporating COS improved the wettability of the CS membrane and increased the antibacterial effects against Escherichia coli and Staphylococcus aureus. The PCL layer prevented water and bacteria adhesion. This wettable membrane has the potential to serve as a new antibacterial dressing for wound healing.

Summary: The combination of plant-derived agents with chemotherapy drugs in PCL nanofibers enhances drug cytotoxicity in cancer cells and improves biocompatibility in normal cells. CALRS and DOX were incorporated into PCL nanofibers, which were characterized using various techniques. The nanofibers exhibited antibacterial, antiparasitic, and anticancer activities. DOX release from the nanofibers followed the Korsmeyer-Peppas model. The DOX and CALRS dual agents-loaded nanofibers showed superior antibacterial activity and anticancer activity compared to pure DOX, CALRS, and DOX loaded-PCL nanofibers.

Summary: An extended-release tablet of tacrolimus as once-daily dosing was fabricated using 3D printing technology. The tablet was developed by combining two 3D-printing methods and met the USP requirements for weight variation, friability, hardness, assay, and content uniformity. SEM analysis showed smooth surfaces with multiple deposited layers, and there was no decomposition of the polymer and drug observed at the printing temperature. The novel 3D-printed tablet with tailored dosing and specific kinetic release has the potential to be used for personalized medicine.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. 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.

The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

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.

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

Summary: This paper reports on the synthesis, structural characterization, spectral and nonlinear-optical properties of glass nanocomposites made of glass forming ionic liquid crystals and nanoparticles. The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
