Revealing the Underlying Mechanisms in Performance Enhancement of Shellular Lattice Electrodes During Anion Exchange Membrane Water Electrolysis Process

Advanced Science, EarlyView.
Micro laser powder bed fusion enables architected nickel shellular lattice gas diffusion layers for anion exchange membrane water electrolysis. Among regular open cell geometries, the Gyroid lattice promotes bubble release, convective reactant replenishment and continuous electron transport, delivering low overpotentials, enhanced charge transfer and ...

Introduction to Fractal Antenna

IJIREEICE, 2016
In this article, the most recent improvements in the field of fractal antenna designing are theoretically and additionally basically checked on and its future extension is talked about. Fractal design is a geometric example that is rehashed at each design and in this way can't be spoken to by exemplary geometry.

Synergistic Mechano‐Fluidic Self‐Fusion of Poly(Vinyl Alcohol)‐Modified Liquid‐Metal Particles for Post‐Treatment‐Free Soft Electronics

Advanced Science, EarlyView.
Poly(vinyl alcohol)‐modified liquid‐metal particles form conductive networks through spray‐induced self‐fusion without additional post‐treatment. Spray impact initiates oxide‐shell rupture and electrical contact, while subsequent Marangoni flow and capillary forces promote particle redistribution, neck growth, and network consolidation. This sequential

MoS2 Memristors Made by Liquid–Liquid Interface Assembly and Ultraprecise Metal Printing

Advanced Electronic Materials, EarlyView.
A cleanroom‐free, fully additive fabrication route combines ultraprecise printed silver electrodes with Langmuir–Schaefer‐deposited bilayer MoS2 to realize ultralow‐power resistive switching devices. The resulting microscale memories exhibit low operating voltages, a large memory window, stable retention and endurance, demonstrating a scalable and cost‐
