Convex Polytopes, Dihedral Angles, Mean Curvature and Scalar Curvature

open access: yesDiscrete & Computational Geometry
We approximate boundaries of convex polytopes by smooth hypersurfaces $Y=Y_\varepsilon$ with {\it positive mean curvatures} and, by using basic geometric relations between the scalar curvatures of Riemannin manifolds and the mean curvatures of their boundaries, establish {\it lower bound on the dihedral angles} of these polytopes.

Allosteric Regulation of RNA Affinity by Motif V‐VI Coupling in West Nile Virus NS3 Helicase

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The rise of flaviviral diseases, including West Nile virus (WNV), presents a growing threat to global public health and underscores the urgent need for new therapeutic strategies. The non‐structural protein 3 helicase (NS3h) of the Orthoflavivirus genus, including WNV, is essential for viral replication and a promising antiviral target ...

Boron Difluoride Chelated Aminoanthraquinone Photosensitizer for Type I Photodynamic Therapy

open access: yesRare Metals, EarlyView.
ABSTRACT Type I photosensitizers capable of generating cytotoxic reactive oxygen species (ROS), with reduced oxygen dependence under photoirradiation, are regarded as a promising phototherapeutic approach for hypoxic solid tumors. Herein, based on the electron donor of 9‐phenyl‐carbazole (Cz) and the electron acceptor of anthraquinone (AQ ...

White‐Light Flexible Crystal With 180° Folding Induced by Halogen‐Bond Network in Organic‐Inorganic Hybrid Perovskite

open access: yesRare Metals, EarlyView.
ABSTRACT Organic‐inorganic hybrid perovskites (OIHPs) with white‐light emission have significant potential in solid‐state lighting and display due to the designable structure and excellent luminescent properties. However, OIHPs are prone to damage during bending due to the brittleness of crystals, which limits their application in the field of flexible

Enhanced Thermoelectric Performance of SnSe Thin Film via Simultaneous Optimization of Texture and Carrier Concentrations

open access: yesRare Metals, EarlyView.
ABSTRACT Polycrystalline SnSe thin film materials have gained increasing attention as a promising solution for fabricating microscale, flexible, self‐powered electronic components in the field of thermoelectric (TE) materials and devices. However, it is still a great challenge to simultaneously achieve preferred crystal orientation and optimize carrier
