The mol-ecular and crystal structure of the title binuclear Zn complex, [Zn(CHO)(CHOH)], with enolated anionic -butyl-aceto-acetate and ethanol was analysed. The coordination polyhedra of the Zn atoms are distorted octa-hedra formed by six oxygen atoms that belong to three ligand mol-ecules and a coordinated ethanol mol-ecule. In the crystal phase, alternating layers can be distinguished parallel to the plane. A Hirshfeld surface analysis showed that there are no strong inter-molecular inter-actions in the structure. The most significant contributions to the overall crystal packing are from H⋯H inter-molecular contacts.

A chicken protein hydrogel (HG) was enzymatically prepared and blended with a carnauba wax-based oleogel (OG) to form bigels (BG) in ratios of 50:50 to 90:10. These systems were infused with thyme essential oil (TEO) at 0.5 %, 1 %, and 2 % v/v to harness its antioxidant properties.

This work examined the effects of molecular weight (2-15 kDa) and concentration (10-30 mg/mL) of chitosan (CTS) on the binding capacity and interface behavior between octenyl succinic acid sodium starch (OSS) and CTS, as well as their effects on the storage stability of emulsions. The results of the isothermal calorimetry titration demonstrated that OSS and CTS were complexed by electrostatic interaction and spontaneous hydrogen bonding driven by enthalpy (ΔH from -3931 to -7983 cal/mol, ΔS from -38.5 to -49.

This study presents an eco-friendly, cost-effective approach for synthesizing highly efficient nanocatalysts with the help of organic waste. Iron nanoparticles (INPs) were synthesized from aqueous extracts of potato, potato peel, and potato leaf and were evaluated for their photocatalytic efficiency for the degradation of methylene blue dye. X-ray Diffraction (XRD) confirmed FeO nanoparticles cubic crystal structure with the smallest crystallite size (9.

The nacre formation process is a fascinating phenomenon involving mineral phase transformations, self-assembly processes, and protein-mineral interactions, resulting in a hierarchical structure that exhibits outstanding mechanical properties. However, this process is only partially known, and many aspects of nacre structure are not well understood, especially at the molecular scale. To understand the interplay between components-aragonite, protein and chitin-of the structure of nacre observed experimentally, we investigate the interactions of a peptide that is part of the protein lustrin A, identified in the nacreous layer of the shell of the abalone Haliotis rufescens, with the (001) crystal surface of aragonite and the chitin molecule.

Hypothesis: Optimizing interfacial positioning of crosslinkers within a reactive self-assembled hexagonal lyotropic liquid crystals (HLLC) system could assist in retaining the hexagonal structure during polymerization and thereby improving water filtration performances of the as-synthesized nanofiltration membranes.
Experiments: The positioning of the hydrophilic crosslinker, poly (ethylene glycol) diacrylate (PEGDA), within the reactive HLLC system was systematically investigated using H and C solid nuclear magnetic resonance (NMR) and small angle X-ray scattering (SAXS) techniques. The structural variation and water filtration performances of these HLLC systems with/without crosslinkers after polymerization were further studied using grazing incidence SAXS (GISAXS) and crossflow filtration tests, respectively.
