S-decorated MoC as efficient catalyst for Li-O battery system.

Lithium-oxygen (Li-O) batteries are considered an important candidate for the next generation of energy storage systems due to their ultra-high theoretical energy density (11 586 mA h g), but their slow kinetic reactions, high overpotential and cyclic instability seriously limit their practical applications. In this study, sulfur modified MoC (S@MoC) cathode materials were prepared by hydrothermal synthesis by sulfur (S) doping to optimize the electronic structure and catalytic activity of MoC (MoC). Experiments show that S@MoC exhibits significantly improved electrochemical performance compared to commercial MoC: its specific capacity is up to 3955 mA h g (commercial material only 508 mA h g), the charge and discharge overpotential is reduced to 0.

The circular RNA circANK suppresses rice resistance to bacterial blight by inhibiting microRNA398b-mediated defense.

Circular RNAs (circRNAs) are prevalent in eukaryotic cells and have been linked to disease progressions. Their unique circular structure and stability make them potential biomarkers and therapeutic targets. Compared with animal models, plant circRNA research is still in its infancy.

Rapid Detection of in Strawberry Using Species-Specific Primers Based on Comparative Genomics.

poses a significant emerging threat to global strawberry production. The success of surveillance strategies and quarantine measures in controlling its international spread depends heavily on the availability of rapid and reliable in-planta detection tools. Polymerase chain reaction (PCR) is the preferred method for detecting systemic infections due to its high sensitivity, specificity, and ease of use.

The Effect of Copper Sulfide Stoichiometric Coefficient and Morphology on Electrochemical Performance.

In this work, CuS, CuS, CuS, CuS and CuS with the same morphology were successfully synthesized by the hydrothermal method. According to the calculation, their galvanostatic charge-discharge (GCD) curves were 43.29 (CuS), 86.
