Spray Tips: Substrate cooling

Supplemental air cooling has two distinct advantages: controlling part temperature and removing overspray and fume debris from the coating surface.

New method for the mechanical tensile testing of micro and nanofibers

Testing the stiffness or tensile strength of fibers in the nano to micro range experimentally, is often very time-consuming. The samples in most cases have to be affixed using adhesive on both ends. Not only curing of the adhesive takes time, but also the sensor to which the fiber is glued cannot be reused. Now researchers from the Technical University of Vienna (TU Wiuen) have developed a test system that overcomes these obstacles.

Studying bulk metallic glasses on the ISS

In Switzerland, Antonia Neels, head of Empa’s Center for X-ray Analytics, has been working on the mysterious material called bulk metallic glasses for about 15 years. Her team investigates the internal structure of metallic glass using various x-ray methods, thereby discovering correlations with properties such as deformability or fracture behavior. In a few months, a sample of metallic glass will be studied in the microgravity of the International Space Station (ISS).
