Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes

Advanced Science, EarlyView.
Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

Achieving Photo‐Activated Circularly Polarized Room Temperature Phosphorescence from Natural Biopolymers

Advanced Science, EarlyView.
This bio‐based chiral luminescent system exhibit photo‐activated CPRTP by anchoring arylboronic acids to hydroxypropyl cellulose (HPC) matrix. Notably, by controlling the drying kinetics, dynamic switchable CPRTP with opposite handedness can be obtained due to a balance of photonic bandgap (PBG) effect and chirality transfer effect induced by the HPC ...

Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...
