High-frequency-link micro-inverter with front-end current-fed half-bridge boost converter and half-wave cycloconverter

, 2013
A high-frequency-link micro-inverter is proposed for integrating a single photovoltaic panel to a local load or utility grid. The number of power switches is minimized in addition to reduced magnetic components in order to design a low cost, light weight,

Stress History Establishes a Transient Tolerant State That Shapes Antibiotic Survival Upon Resuscitation

Advanced Science, EarlyView.
High‐throughput single‐cell analysis of resuscitating bacteria reveals a starvation‐history‐dependent transiently tolerant subpopulation that survives β$\beta$‐lactam exposure by temporarily reducing growth. Distinct from classical persisters, these actively growing yet dynamically modulated cells dominate survival across clinically relevant antibiotic

Scalable Manufacturing of Roll‐to‐Roll Slot‐Die Coated Perovskite Solar Cells

Advanced Science, EarlyView.
Roll‐to‐roll (R2R) slot‐die coating is emerging as a scalable pathway for perovskite solar cells. This mini‐review summarizes advances in ink design, drying control, and electrode integration that enable high‐efficiency flexible devices and modules. Challenges in throughput, stability, and sustainable processing are outlined, guiding the translation of

Amuc_1473 Links Gut Microbes to Skeletal Homeostasis and Counteracts Multifactorial Osteoporosis

Advanced Science, EarlyView.
Amuc_1473, a previously uncharacterized protein enriched in Akkermansia muciniphila‐derived extracellular vesicles, is identified as a gut–bone messenger that promotes osteogenesis and inhibits osteoclastogenesis by engaging transcriptional and translational regulators in bone cells.

Multiple control strategies for smart photovoltaic inverter under network voltage fluctuations and islanded operation

International Journal of Electrical Power & Energy Systems
This article proposes a central control system that communicates with both grid-tied and off-grid control systems to offer various control strategies for operating a smart photovoltaic (PV) inverter. The target is to connect two sets of PV panels and one

tBid‐Mediated Genetic Ablation of Connective Tissue Cells Reveals Their Key Regulatory Function During Limb Regeneration in Axolotls

Advanced Science, EarlyView.
We establish a tBid‐mediated cell ablation system in axolotls, achieve rapid and efficient ablation of multiple cell types, including muscle stem cell, spinal cord cell, and connective tissue (CT) cells. We investigate the role of CT using tBid‐mediated CT ablation and identify its essential role for limb development and regeneration.

Radiation‐Resistant Kr‐Selective MOF With Record Kr/Xe Selectivity at Elevated Pressure

Advanced Science, EarlyView.
ABSTRACT The separation of Kr/Xe from spent nuclear fuel off‐gas is critical, yet most current adsorbents exhibit Xe‐Kr co‐adsorption under elevated pressures, posing challenges for industrial pressure swing adsorption processes. Herein, we present and evaluate a metal‐organic framework, CALF‐20M‐w, engineered for molecular sieving separation of Kr/Xe ...
