Nanocomposites with a well-defined sandwich-like nanostructure were prepared via in situ growing NiCo-layered double hydroxide nanosheets tunable Ni/Co ratios on reduced graphene oxide (rGO). Electrochemical impedance spectra and N2 adsorption/desorption isotherms confirmed that these sandwich nanostructures effectively promoted charge transport enlarged the specific surface area. The nanocomposites Ni : Co = 2 1 exhibited maximum capacitance of 2130 F g-1 at A g-1, excellent rate capability...
Iridium oxide is one of the most important catalysts for water oxidation. The atomic structure this catalyst remains unknown. We have studied anodically grown iridium films using Raman spectroscopy. In addition to deuteration and 18O substitution experiments, theoretical models were also constructed density functional theory interpret experimental data. material was characterized over a large potential range which included that oxygen evolution reaction (0.0–1.8 V). found be composed [IrO6]n...
Abstract 2D transition metal dichalcogenides with a formula MoX 2 (X=S or Se) have been explored as promising earth‐abundant catalysts for hydrogen evolution reaction (HER), especially those 1T phases. Theoretical calculations and experiments indicated that optimal catalytic performance can be achieved by regulating the atomic ratio of S Se in Mo(S 1‐ x ) . However, preparation phase is challenging because differences elements. Here, we propose facile effective hydrothermal method production...
Enhancing the energy stored and power delivered by layered materials relies strongly on improved understanding of intricate interplay electrolyte ions, solvents, electrode interactions as well role confinement.

The presence of structural water in tungsten oxides leads to a transition the energy storage mechanism from battery-type intercalation (limited by solid state diffusion) pseudocapacitance surface kinetics). Here, we demonstrate that these electrochemical mechanisms are linked mechanical response materials during protons and present pathway utilize coupling for local studies electrochemistry. Operando atomic force microscopy dilatometry is used measure deformation redox-active link nanoscale...
TiO2 nanorod (NR) array for perovskite solar cells (PSCs) has attained great importance due to its superb power conversion efficiency (PCE) compared that of the traditional mesoporous film. A compact layer growth NR via spin-coating cannot meet requirements efficient NR-based PSCs. Herein, we have developed and demonstrated insertion a bifunctional extrathin interlayer (5 nm) by atomic deposition (ALD) at interface fluorine-doped tin oxide (FTO)/TiO2 achieve alleviated electron exchange...

Abstract Electrochemical energy storage is the key enabling component of electric vehicles and solar‐/wind‐based technologies. The enhancement stored requires detailed understanding charge mechanisms local electrochemical electromechanical phenomena over a variety length scales from atoms to full cells. Classical techniques, such as voltammetry, represent macroscopic properties, consequently do not allow extract important information about reactions, ions adsorption, intercalations,...
Here we investigate the competitive electrosorption of mono- and divalent phosphate anions through electrochemical desalination- dilatometry-based experiments. Through in situ dilatometry, monitor strain at electrode surface as cations are electrosorbed. Strain measurements show that presence ions promotes a greater than anticipated expansion during cation (Na+) electrosorption. The observed with Na+ equaled HPO42–. Because ionic radius is smaller HPO42–, symmetric suggests do not completely...
Sodium metavanadate (NaVO3) is a promising low-cost candidate as cathode material for sodium-ion batteries (SIBs) owing to its high cycle performance. Its thermal transport, although being central factor limiting practical applications, remains scarce. Herein, we comprehensively investigate the intrinsic transport properties of two phases NaVO3 using unified theory. Importantly, identify hierarchical mechanism in and significant contribution diffusive transport. With combined channels,...
The change in the structure of air-cooling battery thermal management system (BTMS) is demonstrated to improve its cooling performance. In previous research carried out by authors investigating a 4×9 21700 module, several exit areas close entrance area were designed and examined. direction perpendicular channel, while parallel channel. A simulation analysis BTMS optimize It found that with gradual increase wind speed, outlet position gradually shifted towards inlet wall. This can maintain...
Fluoride is one of components the traditional mold flux, but it causes environmental pollution. With increasing requirement protection on metallurgical industry, a trend to develop low fluorine or fluorine-free fluxes in future. In recent years, many scholars have researched some fluxes. However, because action mechanism flux not completely clear, performance composed fluorine-substituting has reached effect fluorine-containing view this, this paper summarizes effects protective slag from...
Enantiopure tetrahydroisoquinolines (THIQs), recognized as privileged skeletal structures in natural alkaloids, have attracted considerable attention from chemists due to their biological and pharmacological activities. Synthetic strategies for optically active THIQs been rapidly extensively developed the past decades. In view of simplicity atom economy, asymmetric reduction N-heteroaromatics, imines, enamines, iminium salts containing an isoquinoline (IQ) moiety should be preferred...
