Summary: This study investigated the durability of epoxy resin after 12-week exposure to UV radiation, aiming to determine the onset of epoxy degradation. Raman spectroscopy, atomic force microscopy, and electrochemical impedance spectroscopy were used to periodically inspect epoxy film on steel substrate systems. The behavior of the polymer was divided into three periods: immunity, degradation initiation, and failure. Raman spectroscopy and AFM topography imaging were able to sense the early degradation initiation, while impedance spectroscopy and local dc current mapping did not show signs of degradation. The results can be useful in selecting appropriate investigation techniques for accurate evaluation of polymer degradation onset.

Summary: The growth of anodic oxide on niobium was investigated in a solution containing P and Ca-EDTA complexes. It was found that below the breakdown potential, thin and uniform oxide layers were formed, while above the breakdown potential, thicker and microporous oxide layers were observed with enrichment of Ca and P. An anodizing potential of around 200 V was identified as a good tradeoff between morphological and compositional properties and resistance to corrosion.

Summary: This study investigates the use of anionic polyacrylamide hydrogels for the removal of cationic dye crystal violet from aqueous solutions. Batch adsorption studies show that the maximum adsorption capacity of the dye is 378 mg/g at an initial concentration of 300 mg/L, pH = 5, T = 298 K, and 0.039 g of the adsorbent. The adsorption mechanism follows the pseudo-second-order model, and the equilibrium adsorption follows the Langmuir model. Thermodynamic analysis suggests that the adsorption process is spontaneous and endothermic. Density functional theory (DFT), molecular dynamic (MD), and Monte-Carlo simulation studies were used to support the experimental findings.

Summary: The aim of this study is to investigate the photocatalytic properties and chemical durability of the CaO-B2O3-V2O5 glasses system. The prepared borovanadate glasses were confirmed to be amorphous. Replacing V2O5 with B2O3 improved the chemical durability, which could be explained by the increase in glass transition temperature. The photodegradation of methylene blue by the prepared photocatalysts followed pseudo-first-order rate kinetics, and 40 CaO-30 B2O3-30 V2O5 showed the highest removal efficiency of about 99% in 180 min.

Summary: The article highlights common pitfalls in the literature, including deductions based on isolated inhibitors, the limitations of quantum methods in accounting for environmental aggressiveness, distrust in interpreting small energy descriptor differences, and the use of simplistic surface models. The study focuses on local reactivity descriptors for the molecule 6-chloro-2-phenylimidazo[1,2-b]pyridazine, and highlights the importance of considering the corrosive medium's nature and concentration. DM and MC methods are used to account for inhibitor-metal interactions and the dynamic aspects of the adsorption process. The study reveals that the adsorption energy of CP-IPZH does not reflect the polarization resistance in different concentrations of HCl.

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.

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.
