An Electrowetting Pump

Advanced Functional Materials, Volume 36, Issue 72, 7 September 2026.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

Post‐Arc Transient Dielectric Recovery Characteristics of Vacuum Interrupter in the Large‐Capacity Generator Circuit Breaker

High Voltage, Volume 11, Issue 4, Page 999-1010, August 2026.
ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)

A Current Reinjection Scheme That Adds Self-Commutation and Pulse Multiplication to the Thyristor Converter [PDF]

, 2006
An old concept proposed to double the pulse number of a line commutated converter and designated "dc-ripple reinjection," is made more effective by the use of self-commutating reinjection switches, such as GTO or IGCT.

Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices

Advanced Physics Research, Volume 5, Issue 7, July 2026.
Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.
