Abstract: During high current density operation, water production in the polymer electrolyte membrane fuel cell (PEMFC) cathode catalyst layer can negatively affect performance by lowering mass transport of oxygen into the cathode. In this paper, a… read more here.

Abstract: Dual-gasochromic supraparticles that undergo rapid eye-readable and gas-specific colour changes upon reaction with hydrogen or ammonia are reported. This functionality is achieved by tailoring the solid-liquid-gas interface within the mesoporous framework of supraparticles via spray-drying. read more here.

Abstract: Sunlight-induced halide segregation in (CH3NH3)Pb(BrxI1−x)3 (1 > x > 0.2), which limits obtainable voltages from solar cells with these perovskite absorbers, reverses upon resting in the dark. However, sustained illumination at ca. 1 sun opens… read more here.

DOI: 10.1039/d5sm00122f
Abstract: We report the synthesis of a functional molecule, a quatertiophene-based surfactant, which can both adsorb at the water/gas interface (surface active molecule) and aggregate through π-π stacking interactions. We assess then the ability of this… read more here.
