The oxygen evolution reaction and its relationship with metal center coordination remain unclear. Here, the authors report that optimization of the local coordination geometry of Co centers plays a crucial role in facilitating the O-O bond formation atop high-valent Co (IV) sites. ...
The molecular interactions at an organic heterointerface govern the performance of many optoelectronic devices. Through a combination of synthesis, spectroscopy and modelling, it has now been shown that specific molecular interactions result in improved formation of the charge-transfer state. ...
Phase change materials (PCMs) have attracted much attention in the field of solar thermal utilization recently, due to their outstanding thermal energy storage performance. However, PCMs usually release their stored latent heat spontaneously as the temperature below the phase transition temperature, ren-...
Then, as the separation and transport of ionic charges occurs in the electrolyte, a significant change in the intrinsic potential difference arises between the work and counter electrodes. The ionic flow is transformed into a steady-state current under the rGO deformation. The pulsed waveform of ...
The activation parameters, Delta H-double dagger and Delta S-double dagger, for the ring-closing reaction (sigma-bond formation process) were determined by the temperature-dependent change of the lifetime. The energy barrier was found to be largely dependent upon the substituents Ar and Ar'. ...
Heat! Well, more specifically, the heat of formation or de-formation (delta = change) of a reaction termed enthalpy (delta H). Typically, chemical reactions occur in a vessel at which the pressure is held constant - we don't want explosions or implosions! If the pressure is constant, ...
Bond-Dissociation Energy In subject area: Pharmacology, Toxicology and Pharmaceutical Science Bond dissociation energy describes the enthalpy change for a homolytic cleavage of a chemical bond, i.e., separation into free radicals. From: Advances in Molecular Toxicology, 2016 About this pageSet ...
DFT calculation sug-gests that the CNTs could change the K+ adsorption energy and decrease K+ diffusion energy barrier, which dramatically enhances K+ storage kinetics. This work offers an effective material engineering approach for designing hierarchical ‘‘all-in-one” electrodes with high ...
