Multiscale fluidic structure
The integrated silicon pillar array is composed of 18 micron tall 800 nm wide pillars in a hexagonal arrangement. The interstitial spaces between pillars form an ordered network of nanofluidic channels. The bifurcating (tree-like) system of channels provide an interface between the network of nanopores and the macroscopic experimental environment.

Computational Science and Engineering

Computational science and engineering, a relatively new discipline centered on the use of computer simulation and modeling, has opened avenues of research for problems that defied traditional scientific experimentation and were too complex for an analytic solution.

Computational science and engineering researchers at UT Knoxville and ORNL develop and apply high-performance computing models and simulation to produce solutions for problems of national and global significance, such as climate change, astrophysics, advanced materials, biological and environmental systems, national security, and national energy infrastructure needs. UT Knoxville and ORNL scientists are engaged in state-of-the-art research in earth systems modeling, nuclear astrophysics, multiscale modeling in materials science, mathematics and algorithms, national security, counterterrorism, energy assurance, advanced imaging and collaborative information processing, cancer simulation, animal disease control, microwave systems, robotics, integrated circuits, microelectronic systems, software development, energy storage and conversion, advanced materials for energy applications, and many other topics.

ORNL and UT Knoxville are home to the world’s fastest and fourth-fastest supercomputers: the 2.3 petaflop DOE Jaguar and the 1.03 petaflop NSF Kraken. These resources, in combination with exceptional facilities for data visualization and storage, provide an extraordinary environment for high performance computing and computational science. The Innovative Computing Laboratory at UT Knoxville is also a world leader in enabling technologies and software for scientific computing. The Innovative Computing Laboratory provides high performance tools to tackle science’s most challenging problems and plays a major role in developing standards for scientific computing.
