Testosterone Delays Bone Microstructural Destruction via Osteoblast‐Androgen Receptor‐Mediated Upregulation of Tenascin‐C

open access: yesAdvanced Science, EarlyView.
This study reveals that Testosterone–Androgen Receptor signaling delays elderly male bone destruction by upregulation of the osteoblastic extracellular tenascin‐C (TNC). The osteoprotective effect of fibrinogen C‐terminus of TNC is demonstrated in male osteoporotic mice model that osteoblast‐specific Ar‐knockout, potentially via inhibition of ...

Ambient Air Deposition Allows Reaching Record Light Use Efficiency in FAPbI3 Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Ambient air deposition of Formamidinium Lead Iodide (FAPbI3) perovskite enables an increase in average visible transmittance (AVT) value by up to 40%, while also enhance the optoelectronic quality of the film, showing fewer defects and a superior morphology. As a result, semi‐transparent devices achieve a record light use efficiency (LUE) value of 4.2%,

Nano‐Oil‐Barrier‐Based Fluttering Triboelectric Nanogenerator

open access: yesAdvanced Science, EarlyView.
This work proposes a wind‐driven nano‐oil‐barrier‐based fluttering triboelectric nanogenerator (NF‐TENG). A nano‐oil barrier is a simple and innovative strategy to maintain a thin lubricant layer for long‐term cycling based on commercial oil‐absorbing sheets and oil‐infusion steps, which can improve both mechanical and electrical stability of TENGs ...
