Abstract Zn‐I 2 battery with four‐electron reaction path (I − /I + ) in the cathode delivers high energy density, which however is thermodynamically not favored as I metastable. Herein, it demonstrated that conjugated 2P valence electrons graphitic framework can be relocated, offering chances to stabilize species. Combinations of elements (B, N, C, O) various configurations are first screened computationally, identifying O─B─C─N optimal structure. In this B‐centered domain, adjacent O and...
Pressure-induced amorphous-to-amorphous configuration changes in Ca-Al metallic glasses (MGs) were studied by performing in-situ room-temperature high-pressure x-ray diffraction up to about 40 GPa. Changes compressibility at 18 GPa, 15.5 GPa and 7.5 during compression are detected Ca(80)Al(20), Ca(72.7)Al(27.3), Ca(66.4)Al(33.6) MGs, respectively, whereas no clear change has been the Ca(50)Al(50) MG. The transfer of s electrons into d orbitals under pressure, reported for pressure-induced...
Here we provide the material design of a possible high temperature multiband superconductor (HTMS) made 'heterostructure at atomic limit' formed by alternate layers electron doped FeAs and CuO2 separated intercalated NdO spacers. This new class materials is derived from two well known superconductors Nd2CuO4 NdOFeAs belonging to cuprate pnictide families, respectively. The calculated local electronic density states show that both Cu Fe bands cross Fermi surface. will (i) superconducting arcs...
An efficient Ag/pyridine co-mediated oxidative arylthiocyanation of activated alkenes via radical addition/cyclization cascade process was developed. This reaction could be carried out under mild conditions to provide biologically interesting 3-alkylthiocyanato-2-oxindoles in good excellent yields. Mechanistic studies suggested a unique NCS• addition path and clarified the dual roles catalytic pyridine as base crucial ligand accelerate oxidation Ag(I) Ag(II), which is likely oxidant...
The REFeAsO (RE = La, Pr, Nd and Sm) system has been studied by RE L(3) x-ray absorption near edge structure (XANES) spectroscopy to explore the contribution of REO spacers between electronically active FeAs slabs in these materials. XANES spectra have simulated full multiple scattering calculations describe different experimental features their evolution with size. feature just above white line is found be sensitive ordering/disordering oxygen atoms layers. In addition, shape resonance...
Arsenic K-edge X-ray absorption near-edge structure (XANES) spectroscopy has been used to investigate the local geometry around pnictogen site in REFeAsO (RE=La, Pr, Nd and Sm) oxypnictides, combined with full multiple-scattering calculations understand different XANES features. The As spectrum for LaFeAsO is found be significantly from other oxypnictides. results suggest that interlayer order/disorder a significant effect on features coupling between FeAs REO spacers being important...

Glove reuse poses risks, as chemicals can persist even after cleaning. Decontamination methods like thermal aeration, recommended by US OSHA, vary in effectiveness. Some studies show promising results, while others emphasize the importance of considering both permeation and tensile strength changes. This research advocates for informed glove reuse, emphasizing optimal aeration temperatures providing evidence to guide users maintaining protection efficiency.
