The Macro Vulnerabilities to the Clean Energy Transition: An Empirical Assessment

open access: yesSustainable Development, EarlyView.
ABSTRACT The macro environment is one of the analytical levels of the multilevel transition perspective that has the potential to shape the clean energy transition. Following the Political, Economic, Social and Technological (PEST) framework, the present study analyzes the paths by which these four macro dimensions jointly shape wind, solar, and ...

A Dual‐Mode Photoconductive Colorimetric Wearable UV‐Dosimeter: Strategies for Tunable UV‐Band Sensitivity

open access: yesSmall, EarlyView.
The harmful ultraviolet component of sunlight necessitates reliable and wavelength‐selective personal UV monitoring technologies. Here, thermally evaporated CuBr thin films enable dual‐mode UV dosimetry through persistent photoconductive and colorimetric responses arising from charge trapping and surface oxide formation.

Defect‐Healed Perovskite Quantum Dots for Optoelectronic Applications in Indoor Photovoltaics and Photoplethysmography

open access: yesSmall, EarlyView.
A novel dispersion‐phase defect‐healing strategy using Br‐doped PbS quantum dots (QDs) significantly stabilizes CsPbI3 perovskite (Pe) QDs by passivating internal vacancies. This approach reduces trap‐assisted nonradiative recombination, enabling high‐performance indoor photovoltaics with exceptional stability.

Triplet Energy Transfer Strategy for Visible Light Activation of Bio‐Based Oxime Esters in Photopolymerization and 3D Printing

open access: yesSmall, EarlyView.
Bio‐based oxime esters are converted into efficient metal‐free photoinitiators for 405 nm LEDs and sunlight by Dexter‑type triplet energy transfer from ITX, enabling fast and deep visible light curing, high‐resolution 3D printing and improved cytocompatibility.

Metal/Si Nanowire Arrays for Hot Electron Catalysis

open access: yesSmall, EarlyView.
Silicon nanowire arrays enhance plasmon‐driven catalysis by strengthening light–matter interactions on Au and Ag nanostructured coatings. Hotspot accessibility, rather than near‐field intensity alone, governs photocatalytic performance, while Ag nanoshells exhibit superior activity. The work establishes high‐surface‐area Si nanowire arrays as versatile
