BLOC: Buildable and Linkable Organ on a Chip
Advanced Materials Technologies, EarlyView.We developed a “Buildable and Linkable Organ on a Chip” (BLOC) that can construct diverse microphysiological systems (MPSs). The BLOC is standardized to the same size and has one of the functions of “Culture,” “Control,” or “Analysis.” Users can freely configure various MPSs, including developing perfusion, cytotoxicity analysis, and biochemical ...

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.
