Lithium-Ion Batteries The cover shows cyclic fluorinated phosphazene compounds as additional stabilizing additives in a state-of-the-art electrolyte for SiOx/C-based lithium ion battery cells. In article number 2203503 Aurora Gomez-Martin, Tobias Placke, and co-workers demonstrate the beneficial properties of these terms gassing, stabilizing, electrochemical performance solid interphase forming...

The MM3 force field has been extended to deal with the lithium amide molecules that are widely used as efficient catalysts for stereoselective asymmetric synthesis. The MM3 force field parameters have been determined on the basis of the ab initio MP2/6-31G* and/or DFT (B3LYP/6-31G*, B3-PW91/6-31G*) geometry optimization calculations. To evaluate the electronic interactions specific to the lithi...

Using ab initio evolutionary simulations, we predict the existence of five novel stable Li-N compounds at pressures from 0 to 100 GPa (Li13N, Li5N, Li3N2, LiN2, and LiN5). Structures of these compounds contain isolated N atoms, N2 dimers, polyacetylene-like N chains and N5 rings, respectively. The structure of Li13N consists of Li atoms and Li12N icosahedra (with N atom in the center of the Li1...

Li(2)O(2), Li(2)CO(3), and Li(2)O are three critical compounds in lithium-air and lithium-ion energy storage systems. Extensive measurements have been carried out to study the chemical species and their evolutions at difference stages of the device operation. While x-ray spectroscopy has been demonstrated to be one of the most powerful tools for such purpose, no systematic study on the irradiat...

Various Biginelli compounds (dihydropyrimidinones) have been synthesized efficiently and in high yields under mild, solvent-free, and eco-friendly conditions in a one-pot reaction of 1,3-dicarbonyl compounds, aldehydes, and urea/thiourea/acetyl thiourea using lithium-acetate as a novel catalyst without the addition of any proton source. Comparative catalytic efficiency of lithium-acetate and po...

Autism spectrum disorders affect millions of individuals worldwide, but their heterogeneity complicates therapeutic intervention that is essentially symptomatic. A versatile yet relevant model to rationally screen among hundreds of therapeutic options would help improving clinical practice. Here we investigated whether neurons differentiated from pluripotent stem cells can provide such a tool u...

The syntheses of benzofused isochalcogenazole derivatives via orf/?o-lithiation of isophtha­ lamides is reported. AUV'-Dialkyl-isophthalamides, C6H4-l,3-(CONHR)2, bearing R = /Pr or fBu substituents are readily ortho metalated by using 3.3 equiv. of «-BuLi/TMEDA. The organo lithium compounds react with S, Se, or Te to give 2-chalcogenol-isophthalamides, C 6H vl,3(CONHR)2-2-XH (X = S, Se, Te). O...

background: b cell cll/lymphoma 2 protein, bcl-2, is an important anti-apoptotic factor that has been implicated in lithium’s neuroprotective effect. however, most studies have focused on assessing the effects of lithium in neurons, ignoring examination of bcl-2 in astrocytes, which also influence neuronal survival and are affected in bipolar disorder. the aim of this study was to evaluate whet...
