Carbon-Caged-Yttria Catalysts for Stable Electrosynthesis of HO in Concentrated Acid.

The electrosynthesis of hydrogen peroxide (HO), with renewable electricity, air, and water as inputs, offers a sustainable alternative to the conventional anthraquinone process. Performing HO electrosynthesis in concentrated acid offers advantages in functionality and energy efficiency over alkaline media yet is currently limited by short longevity. Here, we first investigate the origins of performance loss of oxidized carbon, a proven catalyst for HO electrosynthesis, and observe its gradual reduction to pristine carbon during acidic electrolysis.

Surface Functionalization of Single-Layered TiCT MXene and Its Application in Multilevel Resistive Memory.

MXenes are a new type of two-dimensional material, and they have attracted extensive attention because of their outstanding conductivity and rich surface functional groups that make surface engineering easy and possible for adapting to diverse applications. However, there are scarce studies on surface engineering of MXene. Herein, we demonstrate for the first time that octylphosphonic acid-modified TiCT MXene can be used as an active layer for memory devices and exhibits stable ternary memory behavior.

One-Step Fabrication of Bio-Compatible Coordination Complex Film on Diverse Substrates for Ternary Flexible Memory.

Recently, resistance random access memories (RRAMs) have been studied extensively, because the demand for information storage is increasing. However, it remains challenging to obtain a flexible device because the active materials involved need to be nontoxic, nonpolluting, distortion-tolerable, and biodegradable as well adhesive to diverse flexible substrates. In this paper, tannic acid (TA) and an iron ion (Fe ) coordination complex were employed as the active layer in a sandwich-like (Al/active layer/substrate) device to achieve memory performance.

Mussel-Inspired Polydopamine Coating for Flexible Ternary Resistive Memory.

In recent years, numerous organic molecules and polymers carrying various functional groups were synthesized and used in fabrication of wearable electronic devices. Compared to previous materials that suffer from poisonousness, stiffness and complex film fabrication, we circumvent above matters by taking advantage of mussel-inspired polydopamine as our active material to realize resistive random access memories (RRAMs). Polydopamine thin films were grown on indium tin oxide glass catalyzed by Cu SO /H O and characterized by Fourier infrared spectroscopy (FT-IR), UV/Vis spectroscopy and scanning electron microscopy.

Mycotoxin-containing diet causes oxidative stress in the mouse.

Mycotoxins which mainly consist of Aflatoxin (AF), Zearalenone (ZEN) and Deoxynivalenol (DON) are commonly found in many food commodities. Although each component has been shown to cause liver toxicity and oxidative stress in several species, there is no evidence regarding the effect of naturally contained multiple mycotoxins on tissue toxicity and oxidative stress in vivo. In the present study, mycotoxins-contaminated maize (AF 597 µg/kg, ZEN 729 µg/kg, DON 3.

Effect of interrupted endogenous BMP/Smad signaling on growth and steroidogenesis of porcine granulosa cells.

Bone morphogenetic proteins (BMPs) play a critical role in the growth and steroidogenesis of granulosa cells (GCs). BMP signals act through membrane-bound heteromeric serine/threonine kinase receptors. Upon ligand binding, BMPs activate intracellular Smad proteins and regulate growth and apoptosis in various cell types.
