TL;DR: The Ru@C2N electrocatalyst, made of Ru nanoparticles dispersed within a nitrogenated holey two-dimensional carbon structure, exhibits high turnover frequencies and superior stability in both acidic and alkaline media, comparable to, or even better than, the Pt/C catalyst for the HER.

TL;DR: A layered two-dimensional network structure that possesses evenly distributed holes and nitrogen atoms and a C2N stoichiometry in its basal plane and has potential for use in practical applications is reported.

TL;DR: A novel bio-inspired composite electrocatalyst, iron phthalocyanine with an axial ligand anchored on single-walled carbon nanotubes, demonstrating higher electrocatalytic activity for oxygen reduction than the state-of-the-art Pt/C catalyst as well as exceptional durability during cycling in alkaline media.

TL;DR: In this paper, the formation mechanism of magnetic moments at the edges of graphitic fragments with various spin and geometric configurations has been investigated, and it has been shown that interedge and interlayer interactions between the localized moments can be explained in terms of the magnetic tails of the edge-localized states.

TL;DR: The synthesis of 2D PANI is described via the direct pyrolysis of hexaaminobenzene trihydrochloride single crystals in solid state and contains uniformly distributed nitrogen atoms for multifunctionality; hence, it is anticipated that 2d PANI has strong potential, from wet chemistry to device applications, beyond linear PANI and other 2D materials.
