The nacnac Cu(I) compound [LCu(MeCN)] () (L = [{N(CHMe-2,6)C(Me)}CH]) was reacted with complexes containing aromatic -E ([Cp*Fe(η-E)], E = P (), As (), Cp* = η-CMe), -P ([Cp‴Co(η-P)] (), Cp‴ = η-CHBu) and -E ligands ([Cp‴Ni(η-E)], E = P (), As ()) yielding the heterometallic complexes [(Cp*Fe)(μ,η-E)(LCu)] (E = P (), As ()), [(Cp*Fe)(μ,η-E)(LCu)] (E = P (), As ()), [(Cp‴Co)(μ,η-P)(LCu)] (), [(Cp‴Co)(μ,η-P)(LCu)] (), and [(Cp‴Ni)(μ,η-E)(LCu)] (E = P (), As ()). These complexes are rare examples of the coordination of a group 11 metal to aromatic -E (E = P, As; = 3-5) ligands. All products were comprehensively characterized by crystallographic and spectroscopic methods. Their dynamic behavior in solution was studied by VT (variable-temperature) NMR spectroscopy, and their electronic structures were elucidated by DFT calculations.

Nitrogen fixation is essential for the sustainable development of both human society and the environment. Due to the chemical inertness of the N≡N bond, the traditional Haber-Bosch process operates under extreme conditions, making nitrogen fixation under ambient conditions highly desirable but challenging. In this study, we present an ultrasonic atomizing microdroplet method that achieves nitrogen fixation using water and air under ambient conditions in a rationally designed sealed device, without the need for any catalyst.

Liquid crystal monomers (LCMs), the integral components in the manufacture of digital displays, have engendered environmental concerns due to extensive utilization and intensive emission. Despite their prevalence and ecotoxicity, the LCM impacts on plant growth and agricultural yield remain inadequately understood. In this study, we investigated the specific response mechanisms of tobacco, a pivotal agricultural crop and model plant, to four representative LCMs (2OdF3B, 5CB, 4PiMeOP, 2BzoCP) through integrative molecular and physiological approaches.

This study aims to develop castable polyurethane suitable for applications on wet substrates or underwater construction. Polyurethanes were synthesized using various polyols with similar hydroxyl values, including poly(tetrahydrofuran) polyol, polyester polyol, castor oil-modified polyol, soybean oil-modified polyol, and cashew nut shell oil-modified polyol. The corresponding polyurethane curing products were evaluated for their underwater curing characteristics by volume expansion ratios and adhesion strength on dry and wet substrates, combined with analyses of reaction exothermic behavior, wetting properties on dry and wet substrates, interfacial tension, and microstructure characterization from the perspectives of reaction activity and water solubility.

Caproic acid has broad applications and can be produced from activated sludge via fermentation, but its quality is hindered by ammonia (NH-N) and reactive phosphorus (RP) in the fermentation broth. However, flow-electrode capacitive deionization (FCDI), a novel ion separation technology that operates continuously without secondary pollution seems to be an efficient process that separates the ions. The results showed that at pH 5.

Copper (Cu), a trace element with redox activity, is both essential and toxic to living organisms. Its redox properties make it a cofactor for a variety of proteins, but it also causes oxidative stress, hence the need to maintain intracellular copper homeostasis. However, the role of copper in the regulation of antioxidant defense in bacteria remains unclear, and the involved transcription factors remain to be explored.
