SDSC Supercomputer Simulations Aid in Solving Boron Carbide Mystery

Building upon decades of research on how to make boron carbide even more efficient, an engineering team at the University of Florida (UF) has been conducting simulations using SDSC’s Comet supercomputer to better understand the nanoscale level deformation mechanisms of this important material.

Insects’ Drag-Based Flight Mechanism Could Improve Tiny Flying Robots

Thrips don’t rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, keeping themselves afloat in airflow velocities with a large ratio of force to wing size. In a study published in this week’s Journal of Applied Physics, researchers performed the first test of the drag force on a thrip’s wing under constant airflow in a bench-top wind tunnel. Drawing from experience in microfabrication and nanomechanics, they created an experiment in which a thrip’s wing was glued to a self-sensing microcantilever.

Future of LEDs Gets Boost from Verification of Localization States Within Indium Gallium Nitride Quantum Wells

LEDs made of indium gallium nitride provide better luminescence efficiency than many of the other materials used to create blue and green LEDs, but a big challenge of working with InGaN is its known dislocation density defects that make it difficult to understand its emission properties.
