MXene‐Based Electrocatalysts for Sustainable Nitrogen Conversion: From Ammonia Oxidation to Nitrogen and Nitrate Reduction

Advanced Materials Interfaces, EarlyView.
This review compares MXene‐based electrocatalysis for ammonia oxidation, nitrogen reduction, and nitrate reduction, highlighting reaction‐dependent differences in catalytic performance and stability. MXenes are generally more compatible with cathodic nitrogen and nitrate reduction, whereas anodic ammonia oxidation raises stability concerns.

Signal to noise ratio analysis in virtual source array imaging [PDF]

, 2013
We consider correlation-based imaging of a reflector located on one side of a passive array where the medium is homogeneous. On the other side of the array the illumination by remote impulsive sources goes through a strongly scattering medium.

O Radical‐Induced n‐to‐p Transition in PbS Quantum Dots Enabling Enhanced and Stable Photogating in QD/IGZO SWIR Phototransistors

Advanced Materials Technologies, EarlyView.
An O radical‐induced n‐to‐p transition in PbS quantum dots (QDs) is achieved via atmospheric Ar/O2 treatment, enabling favorable band alignment and stable photogating in PbS QD/IGZO phototransistors. Interfacial defect passivation and Fermi‐level modulation, confirmed by XPS and UPS analyses, effectively suppress dark current, induce a positive VTH ...
