The interactions between the carbon skeleton and the metal atoms of a binary transition metal carbide (BTMC) are particular interest for industrial applications with openning physics and chemitry questions, especially in magnetoelectric (ME) functional materials and cemented carbides. Chromium and carbon BTMCs are a series of intermetallic compounds with typical chemical formulas and sharepolycrystalline powder c somehromium special characteristics.and carbon as precursors, In this paper,and synthesized s we usedingle-phase bluk Cr7C3 (orthorhombic, with space group: Pnma) with high density and good crystallinity by means of high-temperature and high-pressure quenching method (HTHPQM).

ConspectusThe discovery of reversible hydrogenation using metal-free phosphoborate species in 2006 marked the official advent of frustrated Lewis pair (FLP) chemistry. This breakthrough revolutionized homogeneous catalysis approaches and paved the way for innovative catalytic strategies. The unique reactivity of FLPs is attributed to the Lewis base (LB) and Lewis acid (LA) sites either in spatial separation or in equilibrium, which actively react with molecules.

Molecular spin qubits have the advantages of synthetic flexibility and amenability to be tailored to specific applications. Among them, chromophore-radical systems have emerged as appealing qubit candidates. These systems can be initiated by light to form triplet-radical pairs that can result in the formation of quartet states by spin mixing.

Context: The structural stability, ground state magnetic order, electronic, elastic and thermoelectric properties of NdMn in the C15, C14 and C36 polytypic phases is investigated. The magnetic phase optimization and magnetic susceptibility reveal that NdMn is antiferromagnetic (AFM) in C36 phase; and paramagnetic (PM) in C14 and C15 phases respectively. The band profiles and electrical resistivity show the metallic nature in all these polytypic phases and reveal that the C36 phase possesses smaller resistivity.

Noble metal nanoparticles have attracted tremendous attention as the promising signal reporters for catalytic-colorimetric lateral flow immunoassay (LFIA). However, it remains great challenges for improving their stability and catalytic activity. Herein, first, a kind of porphyrinic based metal-organic framework (MOF) was used as a carrier for loading platinum (Pt) nanoparticles to avoid its aggregation.
