The long-term stability of single-atom catalysts is a major factor affecting their large-scale commercial application. How to evaluate the dynamic under working conditions still lacking. Here, taking single copper atom embedded in N-doped graphene as an example, "constant-potential hybrid-solvation model" used reversible transformation between atoms and clusters realistic reaction conditions. It revealed that adsorption H vital driving force for leaching Cu from catalyst surface. more...
The catalytic asymmetric synthesis of silicon-stereogenic organosilicon compounds has been a long-standing challenging task and was recently accomplished through handful transition-metal-catalyzed approaches. Herein we report an organocatalytic desymmetrization strategy for constructing optically active silacycles. In the presence chiral N-heterocyclic carbene (NHC) catalyst, two identical formyl groups on tetrasubstituted silanes are successfully discriminated to undergo stereoselective...
Photoluminescence (PL) of organometal halide perovskite has been broadly investigated as a fundamental signal to understand the photophysics these materials. Complicated PL behaviors have reported reflecting complex mechanisms including effects from crystal defects/traps whose nature still remains unclear. Here in this work we observed, besides enhancement, surprising decline phenomenon methylammonium lead triiodide (CH3NH3PbI3) showing high initial intensity followed by fast time scale...
An expeditious protocol for the assembly of chiral 4,5-dihydropyridazin-3(2H)-ones from α-chloro hydrazones and aliphatic aldehydes via N-heterocyclic carbene (NHC) catalysis is outlined. These in situ-generated 1,2-diaza-1,3-dienes undergo asymmetric [4+2] annulation with NHC-bound enolates to afford desired products bearing a stereogenic center at C4 position. The notable features this approach include good excellent enantioselectivities, high functional group tolerance, mild reaction...
Proof of Authority (PoA) plays a pivotal role in blockchains for reaching consensus. Clique, which selects consensus nodes to generate blocks with pre-determined order, is the most popular implementation PoA due its low communication overhead and energy consumption. However, our study unveils that speed process transactions by Clique severely restricted 1) long delay full (each containing certain number transactions) between nodes; 2) occurrences no-turn blocks, generated if an in-turn block...
Two-dimensional (2D) perovskites are attracting broad attention for their stability and wavelength tunability. However, random crystallization of sample preparation makes it difficult to obtain 2D with pure structure, especially when the number layers is large. Herein, we prepared perovskite (C8H17NH3)2(MA)n-1PbnI3n+1 different (n = 1-10). For first time, experimentally identified band gap energy Eg up 10 by investigating specific pieces crystal emission spectra using fluorescence...

Molar reaction Gibbs function change, molar enthalpy equilibrium constant, and the partial pressure of SO2 NO for simultaneous removal by using aqueous KMnO4/ammonia solution are calculated based on principle chemical thermodynamics. The results show that KMnO4/ ammonia is available.
Perovskite materials have shown ultrasensitivity to atmospheres especially O2, which is due the passivation effect of surface defects. Identification chemical nature defects thus crucial importance for fundamental understanding these materials, extremely difficult by experimental characterization. In this work, we systematically studied adsorption O2 on all possible crystal (001) with three different terminations in CH3NH3PbI3. High-precision electronic structures were obtained employing...
