Article Abstract
A new hexagonal bipyramidal Ni8 cluster is reported and its magnetic behaviour is analyzed. The molecular structure consists of a hexagonal wheel capped by two additional apical Ni(2+) ions. This structure supports ferromagnetic superexchange interactions between adjacent Ni(2+) ions in the wheel and an antiferromagnetic superexchange interaction between the wheel and apical Ni(2+) ions.
β-Glucosidase plays a pivotal role in transforming ginsenosides into specific minor ginsenosides. In this study, total ginsenosides from Panax notoginseng leaves were used as substrates to stimulate the growth of Aspergillus niger NG1306. Transcriptome analysis identified a β-glucosidase gene, Anglu04478 (1455 bp, 484 amino acids, 54.
Heavy metal ions are major contributors to water pollution, posing significant threats to both ecological balance and human health due to their carcinogenic properties. The increasing need for heavy metal detection highlights the advantages of electrochemical methods, which offer high sensitivity and efficiency. Herein mesoporous nitrogen containing carbon (MNC) was utilized for the simultaneous determination of heavy metals using square wave voltammetry technique in the established conditions of a buffer pH of 5.
Modifying the redox properties of transition metals within layered cathode materials represents a pivotal approach in the pursuit of high-performance cathode materials. The recent research has revealed a novel finding: the introduction of Mg into LiNiCoMnO leads to a shift in the oxidation sequence of transition metals during lithium extraction, with Co supplanting Ni as the primary oxidized species during the initial stages of lithium extraction. This alteration in the lattice constants and volume, among other structural parameters, serves to mitigate lattice stress during the charging and discharging cycles.
Herein, we have used a simple synthetic strategy to access a novel non-sulfur fluorescent molecular probe coumarin and 1,8-napthyridine conjugated probe DNCS. The developed probe has great selectivity and sensitivity for detecting Hg ions. Our photophysical properties evaluation for the synthesized probe with different metal ions (Ba, Al, Ca, Bi, Ce, Cd, Cu, Sr, Co, Fe, Cr, Fe, Mn, Hg, Zn, Pb, Ni, and Sn) unveiled the very selective and sensitive fluorescence sensing behavior with Hg ions in the energy window of near UV and visible light radiation in an organic aqueous solvent mixture (EtOH and water).
Shortwave infrared (SWIR)-emitting materials have emerged as superior light sources with increasing demand for potential applications in noninvasive analysis, night vision illumination, and medical diagnosis. For developing next-generation SWIR phosphor-converted light-emitting diodes (pc-LEDs), the scarcity of intense blue-light-pumped broadband SWIR luminescent materials and poor thermal stability of current Ni-activated phosphors are the ongoing challenges. Here, a blue-light-excitable (440 nm) YAlGaO:Cr,Ni phosphor with ultrawide SWIR emission centered at ∼1430 nm (FWHM ∼264 nm) is reported.
