Waste-Derived Natural Polymer Biosorbents for Toxic Metal Ions: Structure–Sorption Relationships, Modification Strategies, and Prospects for Solid-Phase Sensing

Waste-derived natural polymers offer a route to low-cost sorbents for toxic metal ions, but reported performance is difficult to compare because precursor composition, polymer processing, modification, and experimental conditions vary widely. This critical review examines silk fi...

A feeder shift technique to improve the performance of small Radial Line Slot Array (RLSA) antennas

This paper proposes and experimentally verifies a novel feeder shift technique to improve the performance of small Radial Line Slot Array (RLSA) antennas. The technique optimizes slot pair placement by shifting the antenna feeder from the center toward the edge, allowing previous...
