Manipulating hydrogenation pathways enables economically viable electrocatalytic aldehyde-to-alcohol valorization.

Electrocatalytic reduction (ECR) of furfural represents a sustainable route for biomass valorization. Unfortunately, traditional Cu-catalyzed ECR suffers from diversified product distribution and industrial-incompatible production rates, mainly caused by the intricate mechanism-performance relationship. Here, we manipulate hydrogenation pathways on Cu by introducing ceria as an auxiliary component, which enables the mechanism switching from proton-coupled electron transfer to electrochemical hydrogen-atom transfer (HAT) and thus high-speed furfural-to-furfuryl alcohol electroconversion.

Research on stress release and pressure relief mechanism of underlying coal and rock under protective layer mining.

To study the effect and mechanism of coal-rock underground impact pressure prevention and control under the influence of upper protective layer mining. In this paper, the research is carried out based on four factors, namely, the mining stress environment, the mechanical strength of coal and rock, the dynamic load disturbance effect of mining, and the energy loss space of coal and rock. Theoretical calculation and analysis, rock mechanics test, physical similar simulation test and on-site industrial experiments are adopted to study the stress distribution of the coal rock below the influence of the mining of the upper protective layer, overlying strata migration, and the law of mine pressure behavior.

Puzzle Hi-C: An accurate scaffolding software.

High-quality, chromosome-scale genomes are essential for genomic analyses. Analyses, including 3D genomics, epigenetics, and comparative genomics rely on a high-quality genome assembly, which is often accomplished with the assistance of Hi-C data. Curation of genomes reveal that current Hi-C-assisted scaffolding algorithms either generate ordering and orientation errors or fail to assemble high-quality chromosome-level scaffolds.
