Enhancing Al-Air Battery Performance with Beta-d-Glucose and Adonite Additives: A Combined Electrochemical and Theoretical Study.

Al-air batteries are distinguished by their high theoretical energy density, yet their broader application is hindered by hydrogen evolution corrosion. This research focuses Beta (+) d-glucose (S1) and Adonite (S2) as potential corrosion inhibitors for the Al-5052 alloy within a 4 M NaOH solution. Utilizing electrochemical techniques, hydrogen evolution assessments, and surface analyses, our findings indicate enhancements in anode utilization by 21.

Crystal structure, Hirshfeld surface analysis, and calculations of inter-molecular inter-action energies and energy frameworks of 1-[(1-hexyl-1-1,2,3-triazol-4-yl)meth-yl]-3-(1-methyl-ethen-yl)-benzimidazol-2-one.

The benzimidazole moiety in the title mol-ecule, CHNO, is almost planar and oriented nearly perpendicular to the triazole ring. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into a network structure. There are no π-π inter-actions present but two weak C-H⋯π(ring) inter-actions are observed.

Improvement of the catalytic performance of hybrid nanocomposite based on phosphate-benzimidazole in Knoevenagel condensation.

In this work, we have developed a simple and very effective experimental strategy for the reaction of Knoevenagel via the condensation of aromatic aldehydes substituted with active methylene compounds in the presence of hybrid nanocomposites xMCl-yNaPO (MCl = 2,2'-dibenzimidazolyl butane dichlorhydrates), under ecological conditions. The Phosphate-Benzimidazole hybrid nanocomposite as heterogeneous catalysts has demonstrated a high catalytic activity for the Knoevenagel condensation in ethanol as an ecological solvent. It has several advantages such as light reaction conditions, a simple and ecological working procedure.
