CAS QIBEBT group develops solar-driven seawater pervaporation module

The group of JIANG Heqing at QIBEBT designed a 3D thermal film containing artificial photothermal cones with a polypyrrole (PPy) coating via chemical vapor deposition polymerization (CVDP). Absorbance was around 99 % in the entire solar spectrum, comparable to the...

Crust 1 rig system drills 7 km borehole into the earth crust

The land-based rig, jointly developed by Jilin University and Sichuan-based Honghua Group, did the drill in the Singliao basin in northeast China. It can dig as deep as 10 km and plans are to increase drilling capacity to 15 km depth. CAS news release, June 5,...

CAS DICP improves process for electrocatalytic reduction of CO2

The group of Xinhe BAO and colleagues succeeded in preparing a porous Ni-N-doped porous carbon material that is monodispersed by pyrolyzing a zinc/nickel bimetallic zeolite imidazole skeleton (ZIF-8). CO Faradaic efficiency was maintained between 92.0% and 98.0% in a...
