(Phys.org)—In an attempt to harvest the kinetic energy of airflow, researchers have demonstrated the ability to harvest energy directly from the vibrations of a flexible, piezoelectric beam placed in a wind tunnel. While ...
(Phys.org)—An airplane's vortex generators, which look like small fins on its surface, improve the plane's aerodynamics similar to the way in which the dimples on a golf ball improve the ball's aerodynamics: by delaying ...
Early in the pandemic, Víctor Ortega-Jiménez was exploring creeks near his home and observing springtails. The organisms are the most abundant non-insect hexapods on earth, and Ortega-Jiménez suspected their avoidance ...
