Abstract Efficient charge separation and light absorption are crucial for solar energy conversion over solid photocatalysts. This paper describes the construction of Pt@TiO 2 @In O 3 @MnO x mesoporous hollow spheres (PTIM‐MSs) highly efficient photocatalytic oxidation. TiO –In double‐layered shells were selectively decorated with Pt nanoparticles MnO on inner outer surfaces, respectively. The spatially separated cocatalysts drive electrons holes near surface to flow in opposite directions,...

The relationship between handgrip strength (HGS) at baseline and subsequent depressive symptoms among middle-aged older Chinese adults remains highly uncertain. This research endeavored to investigate the effect of functional limitation on association these two variables. A total 5,684 participants aged ≥45 years from China Longitudinal Study Health Retirement (CHARLS) were enrolled, using data 2015 2018 waves. Functional was evaluated based participants' self-reported basic activities daily...

Information on the catalytic mechanism is crucial for understanding heterogeneous catalysis of glycerol hydrogenolysis. In this work, we proposed a simple and effective method to study hydrogenolysis with Cu/Mg–Al mixed-oxide as catalyst. This based memory effect hydrotalcite-derived Mg–Al tunable property hydrotalcite interlayer distance. The experimental results showed that basal spacing could work an tool reflect relationship between desorption products reaction conditions. With tool, H2...

The coastal sediments were considered to contain diverse phages playing important roles in driving biogeochemical cycles based on genetic analysis. However, till now, benthic very rarely isolated, which largely limits our understanding of their biological characteristics. Here, we describe a novel lytic phage (named Shewanella S0112) isolated from the Yellow Sea infecting sediment bacterium genus Shewanella. has high replication capability, with burst size ca. 1170 particles per infected...

Since supervised learning intrusion detection models rely on manually labeled data, the process often requires a lot of time and effort. To make full use unlabeled network traffic data improve detection, this paper proposes an method for industrial control systems based improved comparative SimCLR. Firstly, feature extraction is trained SimCLR using data; linear classification layer added to model; small amount used training fine-tuning model parameters. The simulated Secure Water Treatment...

Die Synthese mesoporöser Pt@TiO2@In2O3@MnOx-Hohlkugeln, die im UV- und sichtbaren Bereich absorbieren, wird von J. Gong et al. in der Zuschrift auf S. 13938 ff. beschrieben. inneren äußeren Oberflächen TiO2@In2O3-Doppelschichtschalen wurden mit Pt-Nanopartikeln bzw. MnOx funktionalisiert. Aufgrund dünner Heteroübergänge räumlich getrennter Cokatalysatoren Ladungsrekombination effektiv reduziert. Diese Hohlkugeln sind daher gute Photokatalysatoren für Oxidation Wasser Alkoholen.
