Science and Technology, nanoscale organic molecules

Caption: NIST researchers made the first confirmed "spintronic" device incorporating organic molecules using a nanoscale pore test structure,

which consisted of self-assembled molecules (shown in white within the middle blue layer in the illustration) sandwiched between nickel and cobalt electrodes (gray top and bottom layers). The pore structure, less than 40 nanometers in diameter, confines the molecules to a very small area, thus enabling good molecule-metal contacts and limiting defects. Credit: D. DeLongchamp/NIST.

Science and Technology, Ocean Circulation

Data Assimilation in High Resolution, Numerical Simulations of the Ocean Circulation, Eric P. Chassignet, Office of Naval Research, Arlington, VA,

The primary goal of this Challenge project is to support the Navy's requirement for generation of optimal estimates of the time-varying ocean state on synoptic time scales on the order of weeks to months and on spatial scales typically on the order of 10-1000 km (mesoscale). Doing this in real time requires interplay between large varied data sets, numerical ocean circulation models, and data assimilation algorithms.

Due to the large demand placed by near-optimal assimilation techniques on raw computing power, this work qualifies as a Challenge project. It has been made possible through the extensive use of High Performance Computing (HPC) assets provided by the High Performance Computing Modernization Program.

Science and Technology, Computational Fluid Dynamics

The Computational Fluid Dynamics CTA covers high performance computations whose goal is the accurate numerical solution of the equations describing fluid and gas motion

and the related use of digital computers in fluid-dynamics research.

CFD is used for basic studies of fluid dynamics for engineering design of complex flow configurations, and for predicting the interactions of chemistry with fluid flow for combustion and propulsion.
