Advanced Materials, EarlyView.A rapid surface reconstruction strategy is proposed to enhance the charge collection efficiency and stability of indium sulfide (In2S3) photoanode via a high‐temperature flame treatment. This method selectively transforms the In2S3 surface into a diffusionless In2O3 and generates bulk sulfur vacancies, resulting in surface‐reconstructed In2S3 (sr‐In2S3)

Contact geometry and the Poincaré conjecture [PDF]
arXiv, 2010 We give a simple proof of the Poincar\'e conjecture by using the contact Ricci flow associated with the Reeb vector field.

Advanced Materials, EarlyView.The hollow gyroid carbon (HGC), synthesized via the self‐assembly of block copolymers and vapor pressure‐induced hollow structuring, provides a robust platform for embedding Pt nanoparticles. The HGC morphology facilitates efficient mass transport while the pyridine N inherent in the block copolymer enhances electrical conductivity and electrochemical ...

Operators Induced by Graphs [PDF]
arXiv, 2010 In this paper, we consider certain elements in von Neumann algebras generated by graph groupoids. In particular, we are interested in finitely supported elements, called graph operators. We study the characterizations for self-adjointness, the unitary property, hyponormality and normality of graph operators.

Covalent Organic Frameworks for Photocatalysis
Advanced Materials, EarlyView.This review provides an overview of recent advances in covalent organic frameworks (COFs) for photocatalysis, focusing on sustainable energy applications like water splitting, hydrogen peroxide generation, and CO2 and N2 reduction. It discusses design principles, structure‐function relationships, challenges in COF photocatalysis, and strategies to ...

Contact 3-manifolds and Ricci solitons [PDF]
arXiv, 2012 A contact 3-manifold $M$ admitting a transversal Ricci soliton $(g,v,\lambda)$ is either Sasakian or locally isometric to one of the Lie groups SU(2), $SL(2,R)$, E(2), E(1,1) with a left invariant metric.
