Abstract High‐performance and affordable electrocatalysts from earth‐abundant elements are desirably pursued for water splitting involving hydrogen evolution reaction (HER) oxygen (OER). Here, a bifunctional electrocatalyst of highly crystalline Mo 2 C nanoparticles supported on carbon sheets (Mo C/CS) was designed toward overall splitting. Owing to the active catalytic nature nanoparticles, high surface area efficient charge transfer in strongly coupled composite, catalysts show excellent...
In this letter, we report a facile self-foaming strategy to synthesize Ni3C nanoparticles embedded in porous carbon network (Ni3C@PCN) by rationally incorporating nickel salt precursor into the source.

This paper develops techniques for reasoning about graph functional dependencies (GFDs). We study the satisfiability problem, to decide whether a given set of GFDs has model, and implication entails another GFD. While these fundamental problems are important in practice, they coNP-complete NP-complete, respectively. establish small model property satisfiability, showing that if ? is satisfiable, then it size bounded by |Σ| Σ; similarly we prove implication. Based on properties, develop...
