Mass‐Transport–Engineered CCM Architecture Employing MPL‐Free Carbon Paper and Graphene‐Coated Ni Foam Channels for High‐Temperature PEM Fuel Cells

Advanced Science, EarlyView.
A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...

Integrated Hydrophilic Interdigitated Network for Silicone Rubber via a Gradient Polarity Modification Strategy

Advanced Science, EarlyView.
This work overcomes the long‐standing challenge of hydrophilic modification of silicone rubber via a gradient polarity modification strategy. By constructing a hydrophilic interpenetrating network within cured SR, simultaneous surface‐to‐bulk modification is achieved while enabling monitoring through a Eu3+ complex fluorescent tracer.

CO2‐to‐CO Electrolysis in Pure Water at Ampere‐Level Current Density and 1000 h Stability via a Rapid‐Transport Fixed‐Charge Interface

Advanced Science, EarlyView.
CO2 reduction in pure water is enabled by a rapid‐transport fixed‐charge interface that couples nanochannels with a cationic microenvironment. This design eliminates the mass transport plateau, stabilizes key reaction intermediates, and suppresses the hydrogen evolution reaction, ultimately achieving ampere‐level current densities and stable operation ...

Neuromuscular blocking agents. Replacement of quaternary ammonium groups in bis-onium compounds by amidinium, guanidinium, thiouronium, sulphonium and sulphoxonium groups

, 1970
The quaternary ammonium groups of suxamethonium have been replaced by amidinium, guanidinium and thiouronium groups. The guanidine compound exhibited competitive neuromuscular activity of a low order of potency; the other compounds were ineffective ...

Spatially Separated Redox Centers in One‐Dimensional Sp2‐Carbon Covalent Organic Frameworks Enable Synergistic Photocatalytic Palladium Recovery and Bisphenol A Mineralization

Advanced Science, EarlyView.
A one‐dimensional sp2‐carbon covalent organic framework with spatially segregated redox centers integrates a dual photosensitizing system and a cationic interface for synergistic photocatalysis. The material achieves exceptional palladium recovery (1749 mg g−1) and bisphenol A mineralization (0.1710 min−1) without sacrificial agents, demonstrating ...
