The USA-Mexico border has its share of issues: from immigration and security to economic and ecological uncertainty. But there are many who see tremendous opportunities about to unfold. In a unique bilateral event organized by Purdue University, University of Texas El Paso, and Universidad Autonoma de Ciudad Juarez, experts gathered to discuss these big ideas in El Paso on day one, and then across the border in Ciudad Juarez, Mexico on day two.

The world's whitest paint, developed by Xiulin Ruan, has earned a Guinness World Records title, and has just been published in the book's 2022 print edition.

It's not every day that college students get the opportunity to teach something to an astronaut! But Karl Akert, a senior in mechanical engineering, has enjoyed several unique opportunities, working with NASA as part of Purdue Engineering's co-op program.

Pavlos Vlachos, professor of mechanical engineering, has been named the St. Vincent Health Professor of Healthcare Engineering in the Regenstrief Center for Healthcare Engineering.

Modern agricultural tractors contain so much cutting-edge technology, they rival even the latest spacecraft. But the back end is still old-school, relying largely on fossil fuels. So any optimization in tractor efficiency is a huge win for the environment. With this in mind, Andrea Vacca has undertaken a $3.2 million Department of Energy project to optimize the hydraulic systems that connect tractors and implements.

What makes pancreatic cancer so deadly is its covert and quick spread. Now, a "time machine" built by Bumsoo Han has shown a way to reverse the course of cancer before it spreads throughout the pancreas.

Summer is the perfect time to learn about air-conditioning and refrigeration, and as the largest academic HVAC lab in the world, Purdue's Herrick Labs is the perfect place. Every summer since 2016, Herrick Labs has hosted a unique cross-cultural learning collaboration, which includes graduate students from Purdue University, Oklahoma State University, and Technical University of Dresden in Germany.

3D-printed objects look impressive, but the printing process is slow, and removing their jagged edges and external support structures requires a lot of tedious post-processing work. The same is true at the nanoscale, where tiny objects are built to incredibly precise tolerances. A team of Purdue University researchers has demonstrated a 3D printing technique that rapidly constructs complex nanoscale 3D objects with smooth features, and can be implemented to build complex macroscale objects on a practical time scale.

After teaching at Purdue Mechanical Engineering for more than 37 years, Dr. Galen King has retired.

The School of Mechanical Engineering at Purdue University invites applications for a tenure-track faculty position in Semiconductor Manufacturing and Advanced Packaging with core expertise in areas including thermomechanical modeling and characterization of devices and packages, semiconductor device and package fabrication, assembly process development, characterization of electronic materials, and sustainable electronics.
