An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

A power‐saving control voltage‐retention circuit for fast‐locking phase‐locked loops with sleep mode

open access: yesElectronics Letters
This study proposes a voltage‐retention circuit (VRC) for a low‐power phase‐locked loop (PLL) designed for mobile interfaces. The PLL, incorporating the proposed scheme, supports the sleep mode to achieve low power consumption and fast switching between ...

Zinc‐Containing Bioactive Glass Programs Macrophage Polarization through Extracellular Traps Regulation for Enhanced Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
Zinc‐containing bioactive glass (ZnBG) promotes diabetic wound healing by regulating macrophage extracellular traps (METs). Specifically, ZnBG reduces oxidative stress and inhibits the PAD4 and NLRP3/caspase‐1/GSDMD signaling pathways, thereby suppressing MET formation.

Direct Voltage Measurement for Sensorless Control of Single‐Stage Current Source Inverter in Motor Drive Applications

open access: yesIET Power Electronics
Current source inverters (CSIs) offer an alternative to voltage source inverters (VSIs) for electric motor applications. CSIs have some advantageous characteristics, such as the ability to inherently boost voltage, the absence of electrolytic capacitors,

Design of a fast-acquisition phase-locked loop for frequency control systems

open access: yesDianzi Jishu Yingyong
Phase-locked loop (PLL) is a negative feedback control system that can achieve phase synchronization of two signals. Its filtering effect can make its passband narrow, and its output frequency automatically track the input frequency.

Coherence Cloning Using Semiconductor Laser Optical Phase-Lock Loops [PDF]

open access: yes, 2009
We demonstrate the concept of coherence cloning where the coherence properties of a high-quality spectrally stabilized fiber laser are transferred to a commercially available high-power DFB semiconductor laser (SCL) using an optical phase-lock loop.

Excited State Opto‐Ionic Reservoir Computing in Hybrid Perovskite Electrochemically‐Gated Luminescent Cells

open access: yesAdvanced Materials, EarlyView.
A neuromorphic computing system exploiting opto‐ionic modulation in lead halide perovskite microcrystals demonstrates high‐dimensional reservoir dynamics with diffraction‐limited node resolution. Leveraging ultrafast excited‐state interactions, it achieves efficient computation (800 pJ/node‐operation), robustly distinguishing 4‐bit pulse sequences ...
