The Impact of Catalyst Layer Composition and Structure on Performance and Durability of PEMWE Anodes

Advanced Materials Technologies, EarlyView.
This article explores a new type of anode for water electrolysis that uses less iridium, a rare and expensive metal. By combining stable iridium oxide with platinum and carbon‐based materials, the authors create a catalyst layer that maintains strong performance.

Remote Modulation of Single‐Atom Catalyst Boosts High‐Valent Cobalt–Oxo Species Generation for Water Purification and Detoxification

Advanced Science, EarlyView.
This study develops a phosphorus‐doped cobalt single‐atom catalyst that enhances high‐valent cobalt–oxo species generation for water purification. This atomic‐level tuning boosts the catalyst's activity by 3.5 times, enabling efficient pollutant degradation. A continuous‐flow reactor achieves high, long‐term removal efficiency, producing water with low

Silicon carbide absorption features: dust formation in the outflows of extreme carbon stars

, 2008
Infrared carbon stars without visible counterparts are generally known as extreme carbon stars. We have selected a subset of these stars with absorption features in the 10-13 $\mu$m range, which has been tentatively attributed to silicon carbide (SiC ...

Biomimetic Adaptive Hydrothermal Balance Fabric‐Based Dual‐Interface Solar Evaporator for Efficient and Stable Desalination

Advanced Science, EarlyView.
This study combines the biological structure of octopuses with the “3D structure” of spacer fabrics to fabricate a dual‐interface solar evaporator with adaptive hydrothermal balance. Water adaptation is achieved through the differentiated design of the upper and lower layers, and dynamic hydrothermal balance is realized by dynamically regulating the ...
