Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

Carbon Energy, EarlyView.
A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%

Overcoming contact issues in bottom‐contact, short‐channel organic transistors with van der Waals conformal contacts

FlexMat, EarlyView.
A new conformal contact transfer strategy is developed to enhance the contact interface quality between organic semiconductors and metal electrodes in bottom‐contact, short channel organic field‐effect transistors. By utilizing interfacial water permeation and surface functionalization, the method achieves a van der Waals conformal contact interface ...

Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

Laser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.
