The Ag(I) atom in the salt, [Ag(C(4)H(6)N(2))(2)]NO(3)·2H(2)O, shows a nearly linear coordination [N-Ag-N = 178.26 (7)°]. The cation, anion and water mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a layer motif extending parallel to (101).

Two Gram-stain-negative, curved-rod-shaped, non-motile and aerobic bacteria W6 and I13 were isolated from marine sediment samples collected from Meishan Island located in the East China Sea. Catalase and oxidase activities and hydrolysis of Tween 40, 60 and 80 were positive for both strains, while nitrate reduction, indole production, methyl red reaction and HS production were negative. Phylogenetic analyses based on 16S rRNA and genome sequences revealed that strains W6 and I13 formed distinct phylogenetic lineages within the genera and , respectively.

Solar-powered electrochemical NH synthesis offers the benefits of sustainability and absence of CO emissions but suffers from a poor solar-to-ammonia yield rate (SAY) due to a low NH selectivity, large bias caused by the sluggish oxygen evolution reaction, and low photocurrent in the corresponding photovoltaics. Herein, a highly efficient photovoltaic-electrocatalytic system enabling high-rate solar-driven NH synthesis was developed. A high-performance Ru-doped Co nanotube catalyst was used to selectively promote the nitrite reduction reaction (NORR), exhibiting a faradaic efficiency of 99.

This study developed a portable arc iKnife ionization mass spectrometry (AII-MS) technique integrating a surgical knife with low-temperature arc plasma to interact with plant tissues. The thermal energy from the arc plasma induces the sputtering of water-containing plant tissues, leading to the formation of aerosols. These aerosols are then charged by plasma-generated ions, producing charged microdroplets that are ultimately detected by a mass spectrometer.

The electrochemical nitrate reduction reaction (NORR) is considered as a promising strategy for addressing environmental pollution and sustainable energy development. In this study, prism-like CuO loaded on copper foam (CuO/CF) was synthesized in a simple solvothermal reaction and an electrochemical reconstruction process. The electrochemical reconstruction process facilitates the formation of a CuO lattice structure on copper foam derived from FU-CF generated by the reaction of copper foam and fumaric acid (HFU) in DMF.

Current lithium batteries experience significant performance degradation under extreme temperature conditions, both high and low. Traditional wide-temperature electrolyte designs typically addressed these challenges by manipulating the solvation sheath and selecting solvents with extreme melting/boiling points. However, these solvent-mediated solutions, while effective at one temperature extreme, invariably fail at the opposite end due to the inherent difficulties in maintaining solvent stability across wide temperatures.
