Article Abstract
Chemical short-range-order has been widely noticed to dictate the electrochemical properties of Li-excess cation-disordered rocksalt oxides, a class of cathode based on earth abundant elements for next-generation high-energy-density batteries. Existence of short-range-order is normally evidenced by a diffused intensity pattern in reciprocal space, however, derivation of local atomic arrangements of short-range-order in real space is hardly possible. Here, by a combination of aberration-corrected scanning transmission electron microscopy, electron diffraction, and cluster-expansion Monte Carlo simulations, we reveal the short-range-order is a convolution of three basic types: tetrahedron, octahedron, and cube. We discover that short-range-order directly correlates with Li percolation channels, which correspondingly affects Li transport behavior. We further demonstrate that short-range-order can be effectively manipulated by anion doping or post-synthesis thermal treatment, creating new avenues for tailoring the electrochemical properties. Our results provide fundamental insights for decoding the complex relationship between local chemical ordering and properties of crystalline compounds.

An electrochemical sensor based on MXene/PANI/SnO nanomaterials was developed for the detection of 4-aminophenol (4-AP). In situ oxidative growth of PANI on the MXene surface effectively hindered the stacking of the lamellae and increased the specific surface area of the composites. Further complexation of tin dioxide with swelling properties of the structure provided adsorption and catalytic sites for 4-AP.

With the continuous development of flexible sensors and flexible energy storage devices, gel materials with good flexibility, toughness, and tunable properties have attracted wide attention. Deep eutectic solvents (DES) have an obvious advantage of thermal and chemical stability over water. Therefore, eutectogels can effectively solve the problem of insufficient stability of traditional hydrogels.

Traditional electrochemical redox assessments offer insights into material properties for charge storage and catalytic kinetics but often fail to link these to specific surfaces, obscuring the structure-performance relationship. Here, we reveal the facet-dependent electrochemical redox behaviors and their connection to oxygen evolution reaction (OER) catalysis using Co(OH) nanosheets and nanorods as models. By correlating redox charge storage capacity and kinetics with distinct exposed surfaces, we uncover diffusion-controlled redox processes on the basal surface and non-diffusion-controlled behavior on the lateral surface and further utilize the distinct redox charging kinetics to differentiate the two.

Ammonia is one of the most important inputs in the global chemical industry, used primarily in fertilizers and explosives. It is increasingly recognized as a potential energy carrier. Its production is dominated by the Haber-Bosch process, which requires high energy consumption and significant capital investment, and contributes significantly to greenhouse gas emissions.

The performance of NiO-based electrocatalysts for the oxygen evolution reaction (OER) is strongly influenced by the interface between the metal support (current collector) and the catalyst layer, which modulates electronic properties and electrochemical activity. This study systematically investigates the solid-solid interface behavior of NiO thin films prepared by reactive magnetron sputtering on Pt, Au, and Ni, followed by electrochemical characterization. Stepwise NiO deposition and X-ray photoelectron spectroscopy reveal distinct band alignment and electronic structure differences at the metal-catalyst interface.
