Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Dual-band dual-polarized transmitarrays at Ka-band

2017 11th European Conference on Antennas and Propagation (EUCAP), 2017
Transmitarray antennas with dual-band and dual-polarization capabilities are studied here numerically. The antennas are designed based on linearly-polarized unit-cells working at Ka-band for satellite applications. The unit-cells include two printed patches and a connecting via; a 180° phase shift is obtained by rotating one of the patches.

Concurrent dual-band LNA for dual-system dual-band GNSS receiver

Analog Integrated Circuits and Signal Processing, 2013
Two concurrent dual-band low-noise amplifiers (LNAs) for GNSS applications are presented. They adopted resistive load and LC resonator load, respectively. On-chip circuits are used for biasing the main amplifiers and active baluns are used for single-ended-to-differential conversions.
