Experimental Box Could Track Nuclear Activity by Rogue Nations

Researchers at the Virginia Tech College of Science are carrying out a research project at Dominion Power’s North Anna Nuclear Generating Station in Virginia that could lead to a new turning point in how the United Nations tracks rogue nations that seek nuclear power. The years-long project centers on a high-tech box full of luminescent plastic cubes stacked atop one another that can be placed just outside a nuclear reactor operated by, say, Iran. The box would detect subatomic particles known as neutrinos produced by the reactor, which can be used to track the amount of plutonium produced in the reactor core.

Energized Fabrics Could Keep Soldiers Warm in Frigid Climates

Soldiering in arctic conditions is tough. Protective clothing can be heavy and cause overheating and sweating upon exertion. And hands and feet can grow numb despite wearing such gear. To keep military personnel more comfortable and battle-ready in bitterly cold climes, scientists are conducting research aimed at creating high-tech fabrics that heat up when powered and capture sweat.

Radiation Tolerant “Smart Backplanes” for Spacecraft Avionics

In recent years there has been a trend towards the wider use of COTS (Commercial Off The Shelf) equipment in space missions. This trend has been mainly driven by the restrictions in R&D budgets and a growing demand for shorter design cycles. Funding Agencies are encouraging designers of spacecraft systems to identify and overcome the obstacles that previously prevented the use of COTS products for space missions.

On-Orbit Satellite Refueling Flow Measurement

The Path from Concept to Operational Status

Over 7000 satellites have been placed in Earth-orbit since the beginning of the space age. 3000 are currently in orbit, of which 1000 are active, making our near space neighborhood a pretty crowded place. Now, plans are in motion to launch constellations of globe-girding communication satellites that will number in the thousands to provide worldwide internet connectivity. This is in addition to the ever-expanding constellation of LEO, geo synchronous and geo stationary satellites. Clearly, the number of satellites in orbit is on a trajectory of significant growth and we are approaching a point when the economics will demand longer life from these expensive assets just as the costs to put them in orbit continue to fall. NASA’s Restore-L mission, under the direction of the Agency’s Satellite Servicing Projects Division (SSPD) headquartered at the Goddard Space Center, is a major step towards realizing key technologies needed to provide in-space satellite servicing in order to increase on-orbit asset life.

Hydrodynamic Drag Force Measurement of a Functionalized Surface Exhibiting Superhydrophobic Properties

Comparing the skin friction drag effects of a superhydrophobic flat plate to an untreated flat plate of the same material and geometry.

With superhydrophobic properties being extended to a variety of metallic substrates through the process of ablation due to femto-second laser surface processing (FLSP), it is important to understand the hydrodynamic benefits of such a material, as well as its resiliency. This research focuses on the skin friction drag effects of a superhydrophobic flat plate compared to an untreated flat plate of the same material and geometry. The resiliency of this material will also be tested through the use of an accelerated corrosion fog chamber using both treated and untreated aluminum samples.
