Implantable micro-devices may one day help regenerate nerves in humans, but for now they are limited by several factors. One limitation is the processing methods used for making the micro-devices, which sometimes require etching patterns into the biodegradable materials. Shoachen Chen is helping medical equipment designers develop micro-devices by improving the processing of biodegradable materials. The Iowa State University professor of industrial and manufacturing systems engineering uses lasers for producing micro-features on polymer surfaces. He is carving out answers to questions about how lasers remove materials from polymers. His work, funded by the National Science Foundation, is important to understanding how designers integrate materials into biodegradable micro-devices.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
