Co/C Nanocomposites with Tunable Condensed States Induced by Conformation-Mediated Strategy for Electromagnetic Wave Absorption.

The strategic regulation of condensed state structures in multicomponent nanomaterials has emerged as an effective approach for achieving controllable electromagnetic (EM) properties. Herein, a novel conformation-mediated strategy is proposed to manipulate the condensed states of Co and C, as well as their interaction. The conformation of polyvinylpyrrolidone molecules is adjusted using a gradient methanol/water ratio, whereby the coordination dynamic equilibrium effectively governs the deposition of metal-organic framework precursors.

Tamoxifen Prevents D-galactosamine/Lipopolysaccharide-Induced Murine Acute Hepatic Failure through Inhibition of Oxidative Stress and Mmd-2 Upregulation.

Oxidative stress is considered one of the major mechanisms underlying lipopolysaccharide (LPS)-induced acute liver failure (ALF). Tamoxifen has been reported to ameliorate LPS-induced ALF via the induction of monocyte to macrophage differentiation-associated 2 (Mmd-2). Whether antioxidant effects are involved remains unknown.
