Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Oxygen Vacancy‐Rich S‐Scheme Heterojunction Photocatalyst With Enhanced Interfacial Charge Transfer for Round‐the‐Clock Formaldehyde Degradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work addresses the critical challenges of severe charge recombination and the dependence on constant light illumination in photocatalysis. We propose a strategy centered on an oxygen vacancy‐rich S‐scheme heterojunction, which enables precise regulation of charge carrier behavior and achieves long‐lasting photocatalytic performance.

Governing Positive Energy Districts: The Role of Legitimation and Identity Across Residential and Industrial Contexts

Environmental Policy and Governance, EarlyView.
ABSTRACT Increasing electricity demand from data centres, industrial applications, electric vehicles and domestic heating is creating pressure to develop electricity systems in many parts of the world, but especially in Western countries. In response to challenges such as grid congestion, interconnection queues and climate‐related hazards, network ...

Revisiting Open‐Circuit Voltage in Heterojunction‐Scarce Organic Solar Cells

Electron, EarlyView.
This work establishes an analytic framework based on the interplay between the composition‐driven density of states and geminate recombination for understanding the open‐circuit voltage of bulk heterojunction‐reduced organic solar cells. ABSTRACT Organic solar cells (OSCs) have reached power conversion efficiencies (PCEs) above 21%, yet their market ...
