Highly Efficient Platinum‐Free Photocatalytic Hydrogen Evolution From Low‐cost Conjugated Polymer Nanoparticles

open access: yesAdvanced Materials, EarlyView.
Platinum‐free hydrogen photocatalysis is achieved using dibenzothiophene‐S,S‐sulfoxide‐based conjugated polymers, self‐assembled into nanoparticles via nanoprecipitation. Through side chain engineering and donor–acceptor design, these materials reach a hydrogen evolution rate of 209 mmol g⁻¹ h⁻¹. The structure–function insights presented here establish

Mixed Ionic and Electronic Charge Transport in Conductive Protein Fibers Revealed with DC Electrical Measurements

open access: yesAdvanced Materials, EarlyView.
M13 bacteriophage films deposited on micro interdigitated electrodes behave as a Randles simplified equivalent circuit under direct current. We derive contact and film resistance as well as capacitance of films of M13 phages, aromatic curli fibers or pilA‐containing nanowires.
