A Janus membrane/mesh is a type of functional membrane/mesh composed of opposing wetting properties formed into a single layer in order to achieve novel properties. Janus membranes/meshes have attracted increasing attention from materials scientists…
N-doping can endow carbon materials with high electrochemical activity. Besides the widely validated sp2-hybridized nitrogen doping, sp-hybridized nitrogen (sp-N) atoms are also expected to be new active sites. However, both sp-N atoms and cyano (CN)…
In order to solve the problems caused by restricted application of offshore hydraulic sand fracturing measures, limited stimulation potential of gneiss matrix acidizing and sand control completion mode, this paper systematically studies the…
