In the title compound, [Co(C(10)H(12)NO(2))(3)]·H(2)O, the Co(III) ion is coordinated by three O atoms and three N atoms from three bidentate 2-eth-oxy-6-(methyl-imino-meth-yl)phenolate ligands in a slightly distorted octa-hedral environment. The water mol-ecule connects two ligands by O-H⋯O hydrogen bonds. One terminal methyl group is disordered over two positions, with site-occupancy factors of 0.412 (15) and 0.588 (15).

We report the synthesis of a series of detergents with a lactobionamide polar head group and a tail containing four to seven perfluorinated carbon atoms. Critical micellar concentrations (CMCs) were determined using isothermal titration calorimetry (ITC) and surface tension (SFT) measurements, showing a progressive decrease from 27 mM to about 0.2 mM across the series.

Magnetic field-dependent magnetization of highly crystalline FeO magnetic nanoparticles has been carried out to understand surface canting structures at low and room temperatures. The exchange bias () values of ∼18 to 27 Oe at 300 K for three samples prepared from different precursors are observed; and a decrease in value is obtained when the samples are measured at 5 K. However, with a decrease in temperature, coercivity () increases.

Atomically precise nanoclusters (NCs) can serve as an excellent platform for a comprehensive understanding of structure-property relationships. Herein, three structurally similar Cu NCs (Cu-1, Cu-2 and Cu-3) have been prepared for the photocatalytic phenylacetylene self-coupling reaction. It was found that Cu-1 NC achieved the highest turnover number (TON) of 524.

Electrochemically converting nitrate (NO ) to value-added ammonia (NH) is a complex process involving an eight-electron transfer and numerous intermediates, presenting a significant challenge for optimization. A multi-elemental synergy strategy to regulate the local electronic structure at the atomic level is proposed, creating a broad adsorption energy landscape in high-entropy alloy (HEA) catalysts. This approach enables optimal adsorption and desorption of various intermediates, effectively overcoming energy-scaling limitations for efficient NH electrosynthesis.
