catalysts is that the atomic number of central B atom should be between group VB and VIIIB, and the electron difference between central A atom and B atom should be large enough, and the selectivity of NRR or hydrogen evolution reaction (HER) could be calculated through the prediction formula...
Herein, a Mg-modified interface was constructed via the simple in-situ electrochemical reduction of Mg2+ from Mg(TFSI)2 in polyethylene oxide (PEO) and a Li bis(trifluoromethane)sulfonimide (LiTFSI) formulae. As confirmed by cryogenic transmission electron microscopy, the anode/electrolyte ...
SURFACES, CHEMISTRY & APPLICATIONS 1.2 Defining the problem The problem of evaluating the fracture energy GIc of polymer interfaces is represented in Fig. 1. Material A is brought into contact with material B to form an A/B interface, the weld is fractured and the strength is related to the...
SURFACES, CHEMISTRY & APPLICATIONS 4.2 Surface and interfacial energetics of polymers and self-assembled monolayers As shown by Dupré's equations (Eqs. 1 and 2), the interfacial thermodynamic work of adhesion between two materials depends on the surface and interfacial energetics. The surface energy...

Computational techniques can speed up the identification of hits and accelerate the development of candidate molecules for drug discovery. Among techniques for predicting relative binding affinities, the most consistently accurate is free energy perturba
Materials Chemistry 1 Introduction Lithium-ion batteries (LIBs) with high energy densities, high output voltages, and long lifespans are widely used in electric vehicles, mobile wearable devices, smart power grids and so forth. To date, traditional nonaqueous LIBs are based on flammable and explosi...
[83], refers to the formation of imine bonds between amine derivatives and aldehydes or ketones. The class of condensation product has the general formula R1R2C=NR3, where R1and R2can be either (a) an aryl or alkyl group, (b) a mixture of the two or (c) a hydrogen atom with R3an...
