Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...

Bridgeless Boost Rectifier With Low Conduction Losses and Reduced Diode Reverse-Recovery Problems

IEEE Transactions on Industrial Electronics, 2007
A bridgeless boost rectifier with low conduction losses and reduced diode reverse-recovery problems is proposed for power-factor correction. The proposed boost rectifier can reduce the conduction losses and alleviate the diode reverse-recovery problems by using a coupled inductor and two additional diodes.

A single-switch continuous-conduction-mode boost converter with reduced reverse-recovery and switching losses

IEEE Transactions on Industrial Electronics, 2003
A single-switch continuous-conduction-mode boost converter with reduced reverse-recovery and switching losses is proposed. By utilizing the leakage inductances of a pair of coupled inductors and two additional rectifiers, the turn-off rates (di/dt) of the boost output rectifier and the additional rectifiers are slowed down to reduce the reverse ...

$p$ -GaN Gate Power Transistor With Distributed Built-in Schottky Barrier Diode for Low-loss Reverse Conduction

IEEE Electron Device Letters, 2020
A 700-V normally-off ${p}$ -GaN gate power transistor with distributed built-in Schottky barrier diode (SBD) is demonstrated in this work. The transistor cell and diode cell are alternately arrayed along the device width and are locally isolated using ion implantations.

Reversible Conductive Hearing Loss in Mice

Annals of Otology, Rhinology & Laryngology, 1988
Fibrin tissue adhesive was injected into the right ears of four 7-week-old CBA/J mice. Auditory brain stem responses (ABRs) were used to monitor changes in auditory sensitivity over the next 26 days, after which the middle ears and cochleas were examined histologically.
