An exsolved Cu-based electrocatalyst from an intermetallic CuSi compound for efficient CH electrosynthesis.

A Cu-based electrocatalyst (-CuSi) is developed by exsolving ultrathin SiO layer-coated CuO/Cu nanoparticles (<100 nm) on the surface of a conductive intermetallic CuSi parent. This specially designed -CuSi catalyst exhibits high performance for the CO reduction reaction (CORR), which affords an excellent CH faradaic efficiency (FE) of 49.0% with partial current density of over 140.

Microsatellite-based analysis of the genetic structure and diversity of Aleurocanthus spiniferus (Hemiptera: Aleyrodidae) from tea plants in China.

Although Aleurocanthus spiniferus (Quaintance) (Hemiptera: Aleyrodidae) is a well known insect pest of tea plants, little information is available about its genetic structure and diversity. The present study used microsatellite markers to assess the genetic structure and diversity of this species on tea plants in China. For this purpose, 193 individuals from ten natural populations were analyzed using ten microsatellite markers.
