Simple synthetic routes, high active layer thickness tolerance as well as stable organic solar cells are relentlessly pursued as key enabling traits for the upscaling of organic photovoltaics. Here, the potential to address these issues by tuning donor polymer molecular weight is investigated. Specifically, the focus is on PTQ10, a polymer with low synthetic complexity, with number average molecular...

The landscape represents a GeTe‐C nanocomposite, a heterogeneous medium made of materials with different elastic properties, as symbolized by mountains and valleys. A travelling phonon is scattered at the interfaces and strongly attenuated. This strong scattering, like in glasses, modifies phonon properties and leads to a low and weakly temperature dependent thermal conductivity....
Alzheimer's Disease Therapy
SSK1‐NPs efficiently delivered SSK1 into the brain, at where SSK1 is specifically cleaved by β‐galactosidase, which in turn induces the apoptosis of senescent cells. Treatment of SSK1‐NP induced apoptosis of senescence cells in the brain and improved cognitive function and memory in aged Alzheimer's disease mice.

Conductive polymers are recognized as ideal candidates for the development of noninvasive and wearable sensors for real‐time monitoring of potassium ions (K+) in sweat to ensure the health of life. However, the low ion‐to‐electron transduction efficiency and limited active surface area hamper the development of high‐performance sensors for low‐concentration K+ detection in the sweat. Herein, a wearable...
Anion exchange membrane water electrolysis (AEMWE) is an attractive method for green hydrogen production. It allows the use of non‐platinum group metal catalysts and can achieve performance comparable to proton exchange membrane water electrolyzers due to recent technological advances. While current systems already show high performances with available materials, research gaps remain in understanding...
Alkaline anion‐exchange‐membrane water electrolyzers (AEMWEs) using earth‐abundant catalysts is a promising approach for the generation of green H2. However, the AEMWEs with alkaline electrolytes suffer from poor performance at high current density compared to proton exchange membrane electrolyzers. Here, atomically dispersed Pt‐Ru dual sites co‐embedded in nanoporous nickel selenides (np/Pt1Ru1‐Ni...
Nuclear energy holds great potential to facilitate the global energy transition and alleviate the increasing environmental issues due to its high energy density, stable energy output, and carbon‐free emission merits. Despite being limited by the insufficient terrestrial uranium reserves, uranium extraction from seawater (UES) can offset the gap. However, the low uranium concentration, the complicated...
