High‐Entropy Alloys and Oxides as Supercapacitor Electrodes: A Structural and Electrochemical Perspective for Energy Storage

Advanced Sustainable Systems, EarlyView.
This study compares the electrochemical performance of high‐entropy alloys (HEA) and oxides (HEO) as supercapacitor electrodes. HEO demonstrates superior energy and power density due to its capacitive behavior and surface redox reactions, while HEA relies on diffusion‐controlled processes.

Modeling Electrical Transport in Random Networks Composed of Metal‐Oxide Nanowires: The Transition from Junction‐Dominated to Nanowire‐Dominated Regime

Advanced Theory and Simulations, EarlyView.
This study proposes a model for the electrical transport properties of random networks of metal oxide nanowires. Based on the characteristic lengths and energies of nanowires, it allows for discussing the transition from the junction‐dominated to the nanowire‐dominated transport regime.

Wearable Systems of Reconfigurable Microneedle Electrode Array for Subcutaneous Multiplexed Recording of Myoelectric and Electrochemical Signals

Advanced Science, EarlyView.
A reconfigurable microneedle electrode array integrated system is developed for minimally invasive and transdermal monitoring of subcutaneous electromyography, reactive oxygen species, and pH values. By assembling discrete thumbtack‐shaped microneedles into an array, the system enables multi‐parameter detection with single‐microneedle resolution.

Weld-bonded titanium structures [PDF]

, 1976
Structurally stronger titanium articles are produced by a weld-bonding technique comprising fastening at least two plates of titanium together using spotwelding and curing an adhesive interspersed between the spot-weld nuggets.

Self‐Adaptive Reflectance Film for Passive Temperature Regulation in Diverse Environments

Advanced Science, EarlyView.
The rising demand for space cooling calls for innovative passive thermal systems. Traditional radiative cooling materials lack efficiency and alignment with cooling needs, limiting their energy‐saving. A smart film (PFSF) that integrates radiative cooling, reflectance tuning, and phase transition, offering adaptable temperature control across climates ...
