Article Abstract
Intermolecular, stepwise functionalization by BH bonds of a (triphosphine)Mo -nitrido complex generated by N splitting is reported. The imido-hydride and di-hydride-amido Mo complexes have been isolated and characterized. Addition of PinBH to the [Mo(H) (N(BPin) )] complex at room temperature results in the liberation of borylamines from the metal center.
Graphene adsorbed on Ru(0001) has been widely used as a template for adsorbing and isolating molecules, assembling organic-molecule structures with desired geometric and electronic properties and even inducing chemical reactions that are challenging to achieve in the gas phase. To fully exploit the potential of this substrate, for example, by being able to tune a graphene-based catalyst to perform optimally under specific conditions, it is crucial to understand the factors and mechanisms governing the molecule-substrate interaction. To contribute to this effort, we have conducted a combined experimental and theoretical study of the adsorption of cyanomethyl radicals (-CHCN) on this substrate below room temperature by performing scanning tunneling microscopy experiments and density functional theory simulations.

Oxidation is a fundamental transformation in synthesis. Developing facile and effective aerobic oxidation processes under ambient conditions is always in high demand. Benefiting from its high energy and good penetrability, ionizing radiation can readily produce various reactive species to trigger chemical reactions, offering another option for synthesis.

Thermal quenching (TQ) of luminescence presents a significant barrier to the effective use of optical thermometers in high-temperature applications. Herein, we report a novel uniaxial negative thermal expansion (NTE) phosphor, YMoO:Yb,Nd, synthesized by a solid-state reaction. Under 980 nm laser excitation, it exhibits excellent thermally enhanced near-infrared (NIR) upconversion luminescence (UCL) performance.
Mastering the surface chemistry of quantum dots (QDs) has enabled a remarkable gas-sensing response as well as impressive air stability. To overcome the intrinsic receptor-transducer mismatch of QDs, PbS QDs used as sensitive NO receptors are spin-coated on top of a few-layer MoS and incorporated into a thin-film transistor (TFT) gas sensor. This architecture enables the separation of the electron transduction function from the chemical reception function.
In the present investigation, 13% ± 0.84 of the extracted and purified phycocyanin from Phormidium versicolor was obtained, with a purity of 0.69 following dialysis.
