Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Hat patch antenna

Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002
A new type of annular patch antenna is presented. At variance of classical annular patch antenna the inner cylindrical wall is metallized. If radiates like a circular patch but has a smaller stored energy and the feed point can be chosen to have an easy matching. >

A patch antenna for HIPERLAN

Wireless Personal Communications, 1996
A patch antenna suited for indoor HIPERLAN is presented. The antenna operates in T M02 mode and its radiation pattern is omnidirectional in azimuth and has a null in the normal direction. An experimental prototype has been designed and tested. A 6.1% bandwidth of VSWR≤2 and 4.2 dB antenna gain were measured at 5 GHz band.
