Interface Topology Driven Loss Minimization in Integrated Photonics: THz Ultrahigh‐Q Cavities and Waveguides

open access: yesAdvanced Materials, EarlyView.
Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Advanced Electrode Materials for Efficient Hydrogen Production in Protonic Ceramic Electrolysis Cells

open access: yesAdvanced Materials, EarlyView.
Protonic ceramic electrolysis cells (PCECs) are a promising intermediate‐temperature hydrogen production technology, leveraging high proton conductivity in electrolytes yet constrained by insufficient catalytic activity and interfacial instability in fuel/air electrodes. This review systematically categorizes advanced electrode materials and critically

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 ...
