Simulation success

Engineering doctoral students win Composites Simulation Challenge

Two University of Delaware mechanical engineering doctoral students working in the Center for Composite Materials, Subramani Sockalingam and Raja Ganesh, took first prize at the American Society for Composites (ASC) inaugural Student Simulation Challenge held Sept. 9 at Pennsylvania State University.

The goal of the 12-hour competition, held during the annual ASC Technical Conference, was to see which student team could best predict the behavior of a composite laminate material that included a pattern of holes. (more…)

Nanoparticles Seen as Artificial Atoms

Berkeley Lab Researchers Observations of Nanorod Crystal Growth Points Way to Next Generation Energy Devices

In the growth of crystals, do nanoparticles act as “artificial atoms” forming molecular-type building blocks that can assemble into complex structures? This is the contention of a major but controversial theory to explain nanocrystal growth. A study by researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) may resolve the controversy and point the way to energy devices of the future.

Led by Haimei Zheng, a staff scientist in Berkeley Lab’s Materials Sciences Division, the researchers used a combination of transmission electron microscopy and advanced liquid cell handling techniques to carry out real-time observations of the growth of nanorods from nanoparticles of platinum and iron. Their observations support the theory of nanoparticles acting like artificial atoms during crystal growth. (more…)

UMD-Led Team Begins Imaging Comet Hartley 2 with Deep Impact Spacecraft

COLLEGE PARK, Md. — Some five years after its July 4th 2005 ‘comet shot’ was seen around the world, the Deep Impact spacecraft has begun regular imaging of a second comet target, Hartley 2. The spacecraft will continue imaging Hartley 2 during and after its closest approach on November 4, providing an extended look at the comet. However, there won’t be any fireworks this time as Deep Impact’s probe craft was destroyed in its deliberate 2005 collision with comet Tempel 1.
