During the Apollo Program, astronauts on the Moon encountered a small menace that created big problems: lunar dust. Similar to how tiny bits of Styrofoam behave on Earth — adhering to...
Application Briefs: Defense
U.S. Army and Marine troops have cultivated a creative, lifesaving technology out of heavy-duty telescoping poles. The CMD fiberglass telescoping push/pull rods, normally used for cable and wire management applications,...

Throughout history, the use of sand tables has been common practice in rehearsing military strategy in the field. Built on piles of sand with scale models of operational...
Application Briefs: RF & Microwave Electronics
One of the greatest dangers to aircraft — playing a role in numerous destructive and fatal accidents around the world — comes in the form of droplets of water. In clean air, cloud...

Acoustic Detection Using Reverberation
Acoustic detection of undersea objects is difficult due to the uncertain environment and even more difficult when the objects are buried in the seabed. First, sediments generate high backscattering noise due to heterogeneous scatters within the sediments, clouding the object.
Briefs: Materials
Geopolymer concrete has been proposed as an alternative to Portland cement concrete in applications requiring high degrees of fire resistance, because the intrinsic chemistry of the geopolymer binder...
Briefs: Materials
AFRL engineers used prototypes of recently developed ground-penetrating radar (GPR) and electronic cone penetrometer (ECP) devices to determine whether voids and anomalies in a particular airfield's subsoil were...
