Layered 2D transition metal dichalcogenides (TMDs) have been suggested as efficient substitutes for Pt‐group metal electrocatalysts in the hydrogen evolution reaction (HER). However, poor catalytic activities in neutral and alkaline electrolytes considerably hinder their practical applications. Furthermore, the weak adhesion between TMDs and electrodes often impedes long‐term durability and thus requires...
Transition metal selenides (TMSs) have enthused snowballing research and industrial attention due to their exclusive conductivity and redox activity features, holding them as great candidates for emerging electrochemical devices. However, the real‐life utility of TMSs remains challenging owing to their convoluted synthesis process. Herein, a versatile in situ approach to design nanostructured TMSs...
Developing highly efficient noble‐metal‐free electrocatalysts with a scalable and environmentally friendly synthesis approach remains a challenge in the field of electrocatalytic water splitting. To overcome this problem, self‐supported fluorine‐modified 2D ultrathin nickel hydroxide (F‐Ni(OH)2) nanosheets (NSs) for the oxygen evolution reaction (OER) and urea oxidation reaction (UOR) are prepared...
A single transistor neuron (1T‐neuron) is demonstrated by using a vertically protruded nanowire from an 8 in. silicon (Si) wafer. The 1T‐neuron adopts a gate‐all‐around structure to completely surround the Si nanowire (Si‐NW) to make a floating body and allow aggressive downscaling. The Si‐NW is composed of an n+ drain at the top, n+ source at the bottom, and p‐type floating body at the middle, which...
The development of pseudocapacitive materials for energy‐oriented applications has stimulated considerable interest in recent years due to their high energy‐storing capacity with high power outputs. Nevertheless, the utilization of nanosized active materials in batteries leads to fast redox kinetics due to the improved surface area and short diffusion pathways, which shifts their electrochemical signatures...
