Multiple-Station Measurements of a Return-Stroke Electric Field From Rocket-Triggered Lightning at Distances of 68-126 km

Antonio Sunjerga, Qi Li, Mi Zhou

Far-field measurements of lightning-produced electromagnetic fields are of high importance for lightning location systems. Data from recorded lightning strokes can be, for example, used to assess the risk of lightning-induced damage in some geographical ar ...

Linear response to a heat-driven spin torque

Jean-Philippe Ansermet, Haiming Yu, Francesco Antonio Vetrò, Christian Caspers, Lucas Fitoussi

The existence of a heat-driven spin torque is demonstrated using Co/Cu/Co spin valves embedded in metallic nanowires. Heat currents flowing in one direction or its opposite were obtained by heating optically one end or the other of the nanowires. The spin ...

Hybrid Core-Shell Nanowire Forests as Self-Selective Chemical Connectors

Bryan Edward Schubert

Conventional connectors utilize mechanical, magnetic, or electrostatic interactions to enable highly specific and reversible binding of the components (i.e., mates) for a wide range of applications. As the connectors are miniaturized to small scales, a num ...
