Electrostatic Self-Assembly-Driven Heterojunction of Cubic CeO/g-CN Nanosheets for Efficient Photocatalytic Hydrogen Evolution and Photoelectrocatalytic Water Splitting: A Hybrid Experimental and Theoretical Study.

Nanohybrid catalysts hold great promise for photocatalysis and photoelectrocatalysis, with significant progress still to be made. We synthesize a graphitic carbon nitride (GCN)-CeO heterojunction via electrostatic self-assembly. Characterization confirms that CeO nanocubes are uniformly anchored onto layered GCN, forming a high-quality interface with abundant active sites.

Design of an aluminium ion battery with a graphyne host: lowest volume expansion, high stability and low diffusion barriers.

Commercialization of aluminium ion battery (AIB) requires limited volume expansion of the host cathode materials after AlCl intercalation, lower activation barrier, high theoretical specific capacity (TSC), cyclic durability and thermodynamic stability. Most of the carbon and non-carbon based cathode hosts explored so far failed to address the issue of volume expansion and there is a lack of clarity about thermodynamic stability. In this work, we employed multipronged first principles computational approaches on α- and γ-graphyne (GY) and showed that α-GY as a promising cathode host addresses each of the above concerns.

Development of short and long-range magnetic order in the double perovskite based frustrated triangular lattice antiferromagnet Ba[Formula: see text]MnTeO[Formula: see text].

Frustrated magnets based on oxide double perovskites offer a viable ground wherein competing magnetic interactions, macroscopic ground state degeneracy and complex interplay between emergent degrees of freedom can lead to correlated quantum phenomena with exotic excitations highly relevant for potential technological applications. By local-probe muon spin relaxation ([Formula: see text]SR) and complementary thermodynamic measurements accompanied by first-principles calculations, we here demonstrate novel electronic structure and magnetic phases of Ba[Formula: see text]MnTeO[Formula: see text], where Mn[Formula: see text] ions with S = 5/2 spins constitute a perfect triangular lattice. Magnetization results evidence the presence of strong antiferromagnetic interactions between Mn[Formula: see text] spins and a phase transition at [Formula: see text] = 20 K.
