Four Purdue ME students have received Graduate Research Fellowships from the National Science Foundation (NSF) for 2020. This is the most from any school at Purdue.

Remote education has forced teachers to use every tool in their toolbox. But augmented reality, which allows both visual and hands-on instruction from any setting, remains out-of-reach for most educators. Karthik Ramani's team has built an app platform called MetaAR, enabling students and teachers to easily collaborate using augmented reality.

Jeff Rhoads' team have developed a low-cost CO2 sensor that determines whether people are present in a room. This allows HVAC systems to save energy by not heating and cooling empty rooms.

In American football, offensive linemen take more hits to the head than any other position. Eric Nauman's research has shown that those hits accumulate to cause real brain damage, even if there is no concussion diagnosis. But his experiments have shown that there may be a simple fix. If offensive linemen started each play standing up, rather than in a three-point stance, hits to the head would be reduced by 40%.

Phonon scattering is a phenomenon that describes how heat is conducted through materials. Until recently, most heat transfer researchers have only studied three-phonon scattering. But Prof. Xiulin Ruan and his team have demonstrated for the first time, through both theory and experimentation, the importance of four-phonon scattering in infrared and Raman spectra.

The School of Mechanical Engineering is pleased to announce the winners for outstanding sophomore, junior, and senior for the academic year 2019-2020. These students have demonstrated academic excellence, exemplified personal integrity, and exercised involvement in the community of Purdue University.

Hand sketching is a great way to bring ideas to life, but many engineers feel they need artistic talent to sketch. Not so! Anyone can do it, if they learn how. Prof. Karthik Ramani is now offering his sketching workshop for engineers, online for free.

As an engineer at 3M, Andrew Penning was pretty happy with his job -- but he felt he could do more. With an online master's in mechanical engineering from Purdue, he found new opportunities to advance his career into research and development.

The beautiful colors of a butterfly come from tiny patterned features that reflect light at certain wavelengths. David Cappelleri's lab has duplicated this feat in mobile microrobots smaller than a human hair, using a micro-3D-printing technique called two-photon polymerization.
