Discovery and genesis mechanism of high content diamondoids in the Gulong shale oil

Scientific Reports
Diamondoids are an important industrial material for biomedicine and equipment manufacturing. In addition to chemical synthesis methods used in industry, direct separation from petroleum is also a potential approach.

Toward Industrial Electrosynthesis of Ethylene: Energy‐Efficient and Stable Acetylene Semi‐Hydrogenation on a Copper Phosphide/MXene Electrocatalyst

Angewandte Chemie International Edition, EarlyView.
Cu3P nanoparticles anchored on MXene via Ti─O─P bonds exhibit enhanced stability and resist agglomeration during the electrochemical semi‐hydrogenation of C2H2 to C2H4. Ti3C2/Cu3P achieves a record energy efficiency of 23.0% at 0.2 A cm−2 and stable operation in a 4 cm2 MEA for over 100 h at 1.0 A.

Microscopic time‐dependent mechanical behavior of shale derived from nanoindentation

Deep Underground Science and Engineering, EarlyView.
This study conducted grid nanoindentation creep tests to systematically analyze the microscopic creep behaviors of shale. Based on the analysis of creep strain rate sensitivity, the primary mechanism of microscopic creep in shale was found to be the extension and closure of microcracks.

Evolution of pore characteristics in oil shale during pyrolysis under convection and conduction heating modes

, 2020
The pores in oil shale, which act as channels for the migration of products of cracking of organic matter and the place for heat transfer in the rock mass, directly influence pyrolysis efficiency.
