Iowa State University professor Vladimir Tsukruk developed a unique polymer coating for micro-electromechanical systems. He uses an electrostatic process that forms a "self-assembling" coating measuring less than ten nm thick that contains both flexible and hard layers. Tsukruk says the coating has low friction and a longer life span than existing single-layer polymers. For more information, contact Tsukruk at (515) 294-6904.
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.
