Rattling effect mechanism on the temperature stability of low-sintered Ca1–x(Li1/2Eu1/2)xWO4 microwave dielectric ceramics for dielectric resonant antenna applications

Journal of Materiomics
The low dielectric constant (εr < 15) is the key to improving the signal transmission speed of microwave communication devices. However, the resonant frequency temperature coefficient (τf) of most low-εr microwave dielectric ceramics is usually negative.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
