Since the beginning of the century, N-hydroxyphthalimide and related compounds have been revealed to be efficient organocatalysts for free-radical processes and have found ample application in promoting the aerobic oxidation of a wide range of organic substrates. When combined with different co-catalysts, they are activated to the corresponding N-oxyl radical species and become able to promote ...

Metal doping for active sites exhibits remarkable potential improving the hydrogen evolution reaction (HER). Multi-doping and use of a conductive substrate can further modulate catalytic performance. Herein, Nb-CoSe well dispersed in N-doped carbon nanospheres (NCs, Nb-CoSe@NC) was synthesized to serve as facilitated good dispersion HER. Nb also change electronic structure CoSe, which facilitat...

Abstract Cationic and anionic clusters of the group-14 elements carbon, silicon, germanium, tin, lead are produced by high-vacuum laser ablation studied with a multi-reflection time-of-flight mass spectrometer. In-trap photodissociation is performed for cluster species in size range $$n =$$ n =</mml:mo...

This review focuses on the impacts of metal-organic interfacial bonding interactions on the charge-transport dynamics involved in molecular junctions as well as organically capped nanoparticles. Whereas mercapto derivatives have been used extensively as the ligands of choice to functionalize metal and nanoparticle surfaces with the formation of metal-thiolate interfacial bonds, recent studies s...

using uv-vis spectrophotometic method, the formation constants for interaction of cd2+(aq) andco2+(aq) ions with l-alanine were experimentally studied at ph = 4.1 ± 0.01 (50mm of potassiumhydrogen phthalate buffer), ionic strength of 0.1m potassium nitrate and at 5 differenttemperatures 15,20, 25,30 and 35°c. the optical absorption spectra of mixtures containingconsidered cations and l-alanine ...

Abstract Current research efforts on single-atom catalysts (SACs) exclusively focus nonmetal or transition-metal atoms as active centers, while employing main-group metal elements is seemingly excluded because their delocalized s/p-bands are prone to yield a broadened resonance for the interaction with adsorbates. Here, we use high-throughput first-principles calculations investigate possible i...

transition-metal-substituted  (tms)  polyoxometalates  of  the  general  formula  [siw9m3o39], (where m = first row transition metal), has been synthesized and supported on anatase by sol–gel method under oil-bath condition. the tetrabutylammonium (tba) salts of the keggin-type polyoxotungstates  [siw9m3o39],  (m = vii, crii, mnii,  feii coii  and niii),  proved  to  be  green, reusable,  and  ...
