Novel triazolium-based ionic liquids (ILs) have been designed and synthesized for the transesterification of palm oil with methanol to produce biodiesel. It is found that triazolium-based ILs herein possessed better thermal stability and higher catalytic activity than the common imidazolium-based ILs. The investigation of reaction condition is conducted for the optimization of the biodiesel production. The yield of biodiesel can therefore reach up to 99.75% under optimal reaction conditions. The reaction kinetic study indicated that pseudo first-order reaction kinetic model is available for the reaction system herein, and the activation energy (Ea) is 86.48 kj.mol(-1) usingthe optimal catalyst.

In-situ cross-linked porous anion exchange membranes with high performance for efficient acid recovery

Jiuyang Lin, Xu Dan, Jing Wang, Sisi Huang, Lihai Fan, Ming Xie, Shuaifei Zhao, Xiaocheng Lin

Summary: This study presents in-situ cross-linked porous anion exchange membranes (AEMs) with tunable microstructures and high diffusion dialysis (DD) performance for acid recovery. The prepared AEMs exhibit significantly superior DD performance due to the high free volume and cross-linked networks within the membranes. The optimized AEM shows 2.6 times higher acid dialysis coefficient (UH+) and 255.4 times higher acid/salt separation factor (S) compared to the commercial DF-120 AEM. Therefore, these low-cost, high-performance in-situ cross-linked porous AEMs can potentially contribute to large-scale acid recovery applications.

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.

Surface adsorption of adenine on pristine and B/N/O/P-doped coronene as a biosensing substrate for DNA detection- DFT study

R. Aneesh Kumar, S. Jamelah Al-Otaibi, Y. Sheena Mary, Y. Shyma Mary, Nivedita Acharjee, Renjith Thomas, Renjith Raveendran Pillai, T. L. Leena

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.
