Most of the world's energy comes from fossil fuels. However, the amount of fossil fuels is finite, and many people are concerned about where our energy will come from in the future. We can turn to alternative, renewable sources of fuel, such as our sun (solar energy) and the winds (wind energy). But what happens when the sun doesn't shine or the winds don't blow? Would we be stuck? Well, that is where the fuel cell comes in. A fuel cell is an electrochemical device that generates electricity… Read more

What makes it possible to create high-technology objects like computers and sports gear? It's the materials inside those products. Materials scientists and engineers develop materials, like metals, ceramics, polymers, and composites, that other engineers need for their designs. Materials scientists and engineers think atomically (meaning they understand things at the nanoscale level), but they design microscopically (at the level of a microscope), and their materials are used macroscopically… Read more

Have you ever seen a car-crash safety test? The airbags always deploy just in time to save the test dummy, which is good news for those of us who travel in cars! What makes the airbag deploy properly? A tiny microelectromechanical systems (MEMS) device called an accelerometer. MEMS devices are used in many applications, from inkjet printer cartridges to neural probes. Typically 1 micrometer (µm) to 1 millimeter (mm) in dimension, MEMS devices require special techniques to make.… Read more
