Boosting CO Electroreduction on Bismuth Nanoplates with a Three-Dimensional Nitrogen-Doped Graphene Aerogel Matrix.

Electrochemical CO reduction reaction (CORR), which uses renewable electricity to produce high-value-added chemicals, offers an alternative clean path to the carbon cycle. However, bismuth-based catalysts show great potential for the conversion of CO and water to formate, but their overall efficiency is still hampered by the weak CO adsorption, low electrical conductivity, and slow mass transfer of CO molecules. Herein, we report that a rationally modulated nitrogen-doped graphene aerogel matrix (NGA) can significantly enhance the CORR performance of bismuth nanoplates (BiNPs) by both modulating the electronic structure of bismuth and regulating the interface for chemical reaction and mass transfer environments.

Controlled Synthesis of Intermetallic Au Bi Nanocrystals and Au Bi/Bi Hetero-Nanocrystals with Promoted Electrocatalytic CO Reduction Properties.

The electrocatalytic properties of metal nanoparticles (NPs) strongly depend on their compositions and structures. Rational design of alloys and/or heterostructures provides additional approaches to modifying their surface geometric and electronic structures for optimized electrocatalytic performance. Here, a solution synthesis of freestanding intermetallic Au Bi NPs, the heterostructures of Au Bi/Bi hetero-NPs, and their promoted electrocatalytic CO reduction reaction (CO RR) performances were reported.

miR-138 inhibits proliferation by targeting 3-phosphoinositide-dependent protein kinase-1 in non-small cell lung cancer cells.

Objective: Underlying mechanisms of non-small cell lung cancer (NSCLC) development remain poorly understood. miR-138 and 3-phosphoinositide-dependent protein kinase-1 (PDK1) have been reported to be involved in the genesis of NSCLC. The aim of this study was to investigate the role and mechanisms of miR-138 and PDK1 in human NSCLC cells.
