Summary: The type and concentration of charged groups in polymers play a crucial role in mucoadhesive interactions. This study investigated the correlation between chemical structure and mucin-polymer interactions by designing cationic poly(amino acid)s with different charge densities. The results showed that the interactions between mucin and polyaspartamides with at least 50% cationic groups displayed a non-linear change, causing increased light scattering. The analysis further revealed that fully cationic polyaspartamide is not necessarily superior, and the maximum adsorbed mass of polymers on mucin occurred at medium cationic group contents. This highlights the importance of cationic polyaspartamides as mucoadhesive excipients due to their multiple functionalities.

Summary: This study investigates the adsorption phenomenon of copper chloride and tin chloride using a quartz crystal adsorbent, revealing that copper chloride adsorption occurs through a mono-layer process while tin chloride adsorption occurs through a double-layer process, showing a multi-interaction characteristic. The physicochemical investigation of the tested models indicates an endothermic complexation mechanism, and the energetic study shows different adsorption energies for CuCl2 and SnCl2 on H2TPP, suggesting different adsorption mechanisms.

Summary: The use of Bacillus licheniformis cells and their metabolites shows potential as a low-cost and environmentally friendly alternative for synthetic compounds in mineral beneficiation techniques. Selective flotation of barite from quartz was achieved, with the cell-assisted separation proving more effective than metabolite-facilitated flotation in both single mineral and mixed samples. The study also demonstrated the ability of B. licheniformis cells to selectively enhance particles hydrophobicity and act as a successful bio-collector.

Summary: Polysaccharides, including xylans from wood, can be processed into films. The solubility of xylans can be improved through oxidative cleavage of the saccharide ring. The degree of oxidation (DO) of xylans affects their solubility, film formation, and stability. High DO xylans showed the smallest hydrodynamic diameter and formed continuous films with significant moisture uptake.

Summary: Thin films of Co-MOF-74 and Ni-MOF-74 were successfully synthesized using the VAC method on Au-coated quartz crystal microbalance substrates. The thin film morphologies were found to be different from the bulk synthesis powders. However, the saturation capacities of the thin films were nearly equivalent to those of the bulk powders, indicating that the VAC method can produce MOF-74 thin films with retained intrinsic properties observed in bulk powders.

Summary: This paper investigates the interaction between silver ion and helicenes, specifically focusing on hexahelicene and heptahelicene. Experimental results suggest that heptahelicene is recommended for silver complexation due to its high adsorption energies and involvement of chemical bonds during the process. Theoretical models SMPG and SMRG were used to analyze the experimental adsorption isotherms, revealing that the adsorption of helicenes is an endothermic phenomenon and lateral interactions between adsorbates play a role in adsorbed quantity decrease at saturation.

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.

Summary: This study investigates the effects of different transition metal decorations on B12N12 nanocages on the adsorption properties of nitrosourea drugs using computational methods. The results reveal the presence of weak non-covalent interactions between metals and nanocages, and the interaction between drugs and nanocages plays a significant role in drug adsorption. Compared to free drugs, the adsorption of drugs on nanocages can facilitate electron transfer, reduce energy gaps and chemical hardness, indicating activity at the target site.

Summary: In this study, the selective oxidation of aromatic aldehydes was investigated using Ru(VI) as a catalyst and hexacyanoferrate (III) as a cooxidant in an alkaline medium. 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.
