Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals
Advanced Functional Materials, EarlyView.Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.

A Euclidean formulation of QFT incorporating finite rotations
Journal of High Energy PhysicsWe formulate thermal quantum field theory on a finite spatial periodic volume incorporating finite rotations. Traditional compactifications at finite temperature without rotations typically involve T 4 $$ {\mathbbm{T}}^4 $$ as the space-time manifold ...

Topology Optimization With Selective Problem Setups
IEEE Access, 2019 Topology optimization has demonstrated its power in structural design under a variety of physical disciplines. Generally, a topology optimization problem is formulated with clearly-defined problem setup.

Boundary properties and construction techniques in general topology [PDF]
, 1995 The aim of this thesis is twofold. First, we investigate spaces defined by asserting that their nowhere dense subsets have certain properties. Secondly, we develop some techniques for the construction of topological spaces.

Advanced Functional Materials, EarlyView.Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Advanced Functional Materials, EarlyView.A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures
Advanced Functional Materials, EarlyView.To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.
