UHPLC–MS based metabolomics study of the ErZhi formula on skeletal muscle against osteosarcopenia focusing on energy metabolism

open access: yesAnimal Models and Experimental Medicine, EarlyView.
ErZhi formula (EZF) is composed of Ligustri Lucidi Fructus (LLF) and Ecliptae herba (EH). Ovariectomized (OVX) and sham rats received 12‐week intragastric treatment with EZF, alendronate, and vehicle saline. Gastrocnemius tissues were harvested to systematically evaluate pharmacodynamic changes in skeletal muscle morphology, mitochondrial ...

Experimental Study on the Enhancement of Heat Transfer Performance in Sintered‐Core Heat Pipes Using CuO Nanofluid

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study presents the design and construction of an experimental system for evaluating the thermal performance of heat pipes, using sintered‐wick heat pipes charged with CuO nanofluids. The device used in this study is a sintered‐wick heat pipe, in which the liquid return is driven by capillary forces within the porous wick structure.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
