Partial thermal atomization of residual Ni NPs in single-walled carbon nanotubes for efficient CO electroreduction.

CO electroreduction (CORR) is an important solution for converting inert CO into high value-added fuels and chemicals under mild conditions. The decisive factor lies in the rational design and preparation of cost-effective and high-performance electrocatalysts. Herein, we first prepare a novel f-SWNTs-650 catalyst a facile partial thermal atomization strategy, where the residual Ni particles in single-walled carbon nanotubes (SWNTs) are partially converted into atomically dispersed NiN species.

The mechanical properties of chimeric silk are improved by expressing the full-length Trichonephila clavipes major ampullate spidroin gene in the silkworm Bombyx mori via recombinant AcMNPV.

Spider silk is a type of natural protein fiber with excellent toughness and tensile strength. The mechanical properties of chimeric silk have been improved by integrating the spider silk protein gene into the silkworm (Bombyx mori) genome, but this strategy requires a long time to produce genetically modified silkworms. In this study, to rapidly produce chimeric silkworms/spider silk with improved toughness and tensile strength, recombinant Autographa californica multiple nucleopolyhedrovirus (AcMNPV), AcMNPV-FHP-MaSp-G, harboring a full-length Trichonephila clavipes major ampullate spidroin G (MaSp-G) gene driven by the silkworm fibroin heavy chain (Fib-H) promoter, was constructed, in which the signal peptide sequence of the MaSp-G gene was replaced by the signal peptide sequence of the Fib-H gene.

Nickel Single Atom Density-Dependent CO Efficient Electroreduction.

The transition metal-nitrogen-carbon (M─N─C) with MNx sites has shown great potential in CO electroreduction (CORR) for producing high value-added C products.

Composite Interval Mapping Based on Lattice Design for Error Control May Increase Power of Quantitative Trait Locus Detection.

Experimental error control is very important in quantitative trait locus (QTL) mapping. Although numerous statistical methods have been developed for QTL mapping, a QTL detection model based on an appropriate experimental design that emphasizes error control has not been developed. Lattice design is very suitable for experiments with large sample sizes, which is usually required for accurate mapping of quantitative traits.
