Summary: This study investigates the piezocatalytic and adsorption effects of different phases of polymorphic 1T MoS2 nanofibers. Experimental results show that few-layer 2H MoS2 nanofibers exhibit a considerably high piezoelectric potential compared to few-layer MoS2 nanofibers. Additionally, the 2H MoS2 nanofibers generate hydroxyl species and degrade dye molecules through the piezopotential. These findings suggest a dual piezocatalysis-adsorption behavior of polymorphic MoS2 nanofibers.

Summary: The size effect on nanoparticles plays a crucial role in catalysis performance. Tuning the oxygen vacancies on a metal-oxide support can help reduce the size of Pt particles, thus improving the catalysis performance of the supported catalyst. In this study, Ce-Sn solid solutions (CSO) with abundant oxygen vacancies were synthesized. After CO reduction, the catalytic CO oxidation performance of Pt/CSO was significantly better than that of Pt/CeO2. This improvement was attributed to the creation of smaller Pt clusters on CSO with more exposed active sites.

Summary: Electrochemical CO2 reduction reaction (CO2RR) is a significant process for recycling excessive CO2 in the atmosphere. However, the discovery of efficient catalysts for CO2RR is currently lagging behind due to limitations in current methods. To overcome this, researchers have increasingly used modern machine learning (ML) algorithms to accelerate catalyst screening and deepen our understanding of the mechanism. In this review, we examine recent applications of ML in CO2RR research, categorizing them by the types of electrocatalysts, and provide an introduction to the general methodology as well as a discussion on the pros and cons of such applications.

It can detect microRNA-21 (miRNA-21) and microRNA-155 (miRNA-155) with high sensitivity. The biosensor operates by generating a double-helix chain in the presence of miRNA-21, while miRNA-155 inhibits the completion of the reaction. The self-powered biosensor allows for simultaneous ultrasensitive detection of miRNA-21 and miRNA-155, with detection limits of 0.15 and 0.66 fM, respectively. It also demonstrates highly sensitive detection in human serum samples.
