Role of Metallic Ag over Ag/MnO Catalysts for Ozone Decomposition under Humid Conditions.

Ag/MnO catalysts have great potential for practical application in ozone (O) decomposition due to their superior activity under humid conditions. Metallic Ag nanoparticles (Ag) have been identified as the critical active site for O decomposition over Ag/MnO catalysts. However, the role of Ag over Ag/MnO catalysts during the O decomposition remains unclear.

Photothermal-assisted S-scheme heterojunction of CuSnS/MnCdS for enhanced photocatalytic hydrogen production.

Photocatalytic hydrogen evolution is regarded as an economically viable and environmentally benign strategy. However, the practical application of photocatalytic hydrogen production is constrained by the sluggish reaction kinetics and rapid recombination of photogenerated charge carriers. Herein, a CuSnS/MnCdS (CTS/MCS) S-scheme photocatalyst with photothermal effect was synthesized via an ultrasound-assisted self-assembly method and applied for the first time to photocatalytic hydrogen evolution.

Efficient regulation of surface hydroxyl groups on a Pt/Na/AC catalyst using two-step nonthermal plasma for high formaldehyde oxidation performance.

A novel catalyst was fabricated using a two-step nonthermal plasma method by regulating surface hydroxyl groups on Na/activated carbon (AC) with 0.1 wt% Pt loading (Pt/Na/AC (P&P)) and achieved high formaldehyde (HCHO) oxidation performance at ambient temperature. Based on characterization results, we found that in the first step of nonthermal plasma treatment under argon-water, the proportion of terminal OH groups (ter-OH groups) evidently increased.

Fatty acids promote migration of CD4 T cells through calcium release-activated calcium modulator ORAI1 sensitive glycolysis in dairy cows.

Nutritional and metabolic state in dairy cows are important determinants of the immune response. During the periparturient period, a state of negative energy balance in the cow increases plasma concentrations of fatty acids (FA), which are associated with inflammation. Among immune cells, CD4 T are able to function under high-FA conditions, but the underlying mechanisms regulating these events remain unclear.

Bioinspired Asymmetric-Adhesion Janus Hydrogel Patch Regulating by Zwitterionic Polymers for Wet Tissues Adhesion and Postoperative Adhesion Prevention.

Asymmetrically adhesive hydrogel patch with robust wet tissue adhesion simultaneously anti-postoperative adhesion is essential for clinical applications in internal soft-tissue repair and postoperative anti-adhesion. Herein, inspired by the lubricative role of serosa and the underwater adhesion mechanism of mussels, an asymmetrically adhesive hydrogel Janus patch is developed with adhesion layer (AL) and anti-adhesion layer (anti-AL) through an in situ step-by-step polymerization process in the mold. The AL exhibits excellent adhesion to internal soft-tissues.

Capture of single Ag atoms through high-temperature-induced crystal plane reconstruction.

The "terminal hydroxyl group anchoring mechanism" has been studied on metal oxides (AlO, CeO) as well as a variety of noble and transition metals (Ag, Pt, Pd, Cu, Ni, Fe, Mn, and Co) in a number of generalized studies, but there is still a gap in how to regulate the content of terminal hydroxyl groups to influence the dispersion of the active species and thus to achieve optimal catalytic performance. Herein, we utilized AlOOH as a precursor for γ-AlO and induced the transformation of the exposed crystal face of γ-AlO from (110) to (100) by controlling the calcination temperature to generate more terminal hydroxyl groups to anchor Ag species. Experimental results combined with AIMD and DFT show that temperature can drive the atomic rearrangement on the (110) crystal face, thereby forming a structure similar to the atomic arrangement of the (100) crystal face.

Efficient porphyrin integrated UiO-66 probes for ratiometric fluorescence sensing of antibiotic residues in milk.

Dual-emissive fluorescence probes were designed by integrating porphyrin into the frameworks of UiO-66 for ratiometric fluorescence sensing of amoxicillin (AMX). Porphyrin integrated UiO-66 showed dual emission in the blue and red region. AMX resulted in the quenching of blue fluorescence component, attributable to the charge neutralization and hydrogen bonds induced energy transfer.

Modulating the Electronic Structures of Pt on Pt/TiO Catalyst for Boosting Toluene Oxidation.

Surface hydroxyl groups commonly exist on the catalyst and present a significant role in the catalytic reaction. Considering the lack of systematical researches on the effect of the surface hydroxyl group on reactant molecule activation, the PtO/TiO and PtO(OH)/TiO catalysts were constructed and studied for a comprehensive understanding of the roles of the surface hydroxyl group in the oxidation of volatiles organic compounds. The PtO/TiO formed by a simple treatment with nitric acid presented greatly enhanced activity for toluene oxidation in which the turnover frequency of toluene oxidation on PtOx/TiO was around 14 times as high as that on PtO(OH)/TiO.

Porcine epidemic diarrhea virus E protein induces formation of stress granules and attenuates protein translation through activation of the PERK/eIF2α signaling pathway.

Porcine epidemic diarrhea virus (PEDV) envelope protein (E) has been characterized as an important structural protein that plays critical roles in the interplay with its host to affect the virus life cycle. Stress granules (SGs) are host translationally silent ribonucleoproteins, which are mainly induced by the phosphorylation of eIF2α in the PERK/eIF2α signaling pathway. Our previous study found that PEDV E protein caused endoplasmic reticulum stress response (ERS)-mediated suppression of antiviral proteins' translation.
