Creating Biofuel
One production technique for biofuel converts agricultural waste through pyrolysis. These systems heat biomass particles in a mixture of sand and nitrogen gas until the biomass particles release tar and syngas, a Keep reading
Swirling Vortex
So much of fluid dynamics comes down to finding the right way to observe a flow. This image of a swirling tropical system was captured by an astronaut aboard the Keep reading
The Microscopic Ocean
When you’re the size of plankton, water may as well be molasses. Viscosity rules at these scales, and swimming plankton leave distinctive wakes that are slow to dissipate. Fish that feed on plankton use Keep reading
Fast-Switching Multi-Material 3D Printer
