Article Abstract
Although water is considered detrimental for Li-ion battery technology, a 1% w/w amount of water in a melt of LiCl in ionic liquid 1-butyl-3-methylimidazolium chloride promotes the reduction of lithium into a LiAl intermetallic along with water oxidation to O gas. The electrodeposition of an intermetallic layer of several micrometers thickness is demonstrated by combining complementary techniques, such as galvanostatics, X-ray diffraction, electron energy-loss spectroscopy, mass spectrometry, and H nuclear magnetic resonance. The concentration of water in the ionic liquid is found to be a critical feature, as no Li is deposited when ionic liquid is dried. Our findings highlight an innovative and simple method to produce a LiAl intermetallic by using water and lithium chloride as chemical reagents.

Worldwide, marine shell waste generated from the seafood industry has emerged as a significant environmental challenge. Indeed, this shell waste represents an abundant source of various valuable products, particularly chitin. However, the extraction and subsequent processing of chitin are hindered by the inherently resistant structure of these chitin-rich feedstocks, coupled with strong hydrogen bonding between chitin chains.

The bisphenols (BPs) contaminants with distinctive endocrine-disrupting properties have garnered significant attention. A new analytical methodology was proposed for the sensitive detection of hazardous BPs in efficient and food safety monitoring. The approach utilizes an ionic liquid-modified covalent organic framework (SCOF-V/IL-5F) as a solid-phase extraction adsorbent to enrich harmful BPs.

Aramid films are potential separator candidates for high-safety lithium-ion batteries (LIBs) due to their inherent flame retardancy and outstanding thermal stability. However, both weak liquid electrolyte wettability and poor mechanical properties of aramid separators for lithium-ion batteries result in low ionic conductivity and unsatisfactory electrochemical performance for LIBs. Herein, a novel asymmetric porous composite separator composed of a relatively dense nanocellulose (CNC) layer and a porous poly(m-phenylene isophthalamide) (PMIA) supporting layer has been fabricated by using a water-induced phase conversion process.

Glyphosate (GLY) is the most widely used herbicide globally. Despite concerns regarding its potential adverse effects on human health and the environment, its use continues to grow each year. Following application, a substantial proportion of glyphosate infiltrates the soil, where it can degrade into transformation products such as aminomethylphosphonic acid (AMPA), which is much more persistent than the parent compound.

An unprecedented recyclable system of copper-catalyzed C-C/N coupling of isatins and DMSO without any oxidant and acidic/basic additive has been unlocked. The -isatins occur tandem -methylation and C5-methylthiomethylation in order, while -substituted isatins proceed C5-methylthiomethylation only. DMSO serves as Me and MeSCH sources as well as the solvent.
