The Drift Region Width Modulation Technique for Breakdown Performance Enhancement of AlGaN/GaN HEMT

IEEE Journal of the Electron Devices Society, 2022
The breakdown performance of the AlGaN/GaN high electron mobility transistor (HEMT) is limited by the high electric field peaks in the device. To obtain a more uniform electric field distribution, the drift region width modulation (DWM) technique is ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Cocoon-mimetic feature-matched interface for flexible system

npj Flexible Electronics
Flexible hybrid systems usually combine soft modules (mechanically matched with skin or clothes) and hard modulus (like rigid circuits). However, the risk of interface failure due to modulus mismatch between flexible components and rigid circuits limits ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
