Capillary‐Driven 3D Open Fluidic Networks for Versatile Continuous Flow Manipulation

open access: yesAdvanced Materials, EarlyView.
The capillary‐driven 3D open fluidic networks (OFNs), composed of connected polyhedral frames, enable precise, programmable, and versatile manipulation of unary, binary, and multiple continuous flows in both spatial and temporal dimensions. OFNs represent a significant leap beyond conventional microfluidics, unlocking new possibilities for selective ...

Bias‐Free Solar Upcycling of Nitrate and Glycerol with Highly Efficient and Durable Organic Semiconductor‐Based Photoelectrodes

open access: yesAdvanced Materials, EarlyView.
A bias‐free photoelectrochemical (PEC) upcycling system integrating bi‐functional nickel‐iron‐phosphorus (Ni‐Fe‐P) catalysts with organic semiconductor (OS)‐based dual photoelectrodes is reported. The system enables simultaneous solar‐driven conversion of nitrate to ammonia and glycerol to formic acid with high efficiency and stability.
