Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes

Advanced Science, Volume 13, Issue 13, 3 March 2026.
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.

Synaptic Behavior in SnSe2 Field‐Effect Transistors Induced by Surface Oxide and Trap Dynamics

Advanced Electronic Materials, Volume 12, Issue 5, 9 March 2026.
Multilayer SnSe2 field‐effect transistors display gate‐tunable optoelectronic plasticity driven by interfacial trap states. Persistent photocurrent is reversibly tuned between short‐ and long‐term memory through gate bias and pulsed control. The devices emulate synaptic functions such as potentiation, modulation, and cumulative learning, establishing ...

Co0/Co2+ Engineered N/O‐Doped Porous Carbon Catalysts for High‐Performance CO2 Hydrogenation Under Mild Conditions

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
Benzimidazole‐derived N/O‐doped porous carbon (BIDC) stabilizes cobalt nanoparticles with tunable Co0/Co2+ sites for low‐temperature CO2 hydrogenation. Co2+ promotes CO2 adsorption/activation, while Co0 enables H2 dissociation. Adjusting the Co0/Co2+ ratio and conditions switches selectivity from CH4 to alcohols.
