Notable Technical Inquiry

Who are the top global researchers and organizations in low, observable (LO) material science?

DSIAC was asked to search available databases to identify the top global researchers and organizations in LO material science.  DSIAC searched multiple literature databases, including Elsevier's Scopus and Clarivate's Web of Science (WoS), to provide information on the publications, number of citations, and patents awarded in LO material science technology and research development. Lists of the top global researchers and affiliations were compiled based on patents awarded and Scopus and WoS database publications and citations.

Voice From The Community

Tyler Englestad

Dr. Englestad, recently appointed as the integrated threat analysis and simulation environment (ITASE) systems lead,oversees the development and maintenance of 200+ intelligence community (IC) validated threat models. ITASE is the IC-wide modeling and simulation architecture designed to provide threat-representative, systems-of systems, kill-chain analysis for the Department of Defense. He is also a computational fluid dynamics subject mater expert for DIA’s MSIC where Tyler Englestand, ITASE Systems Lead, Defense Intelligence Agency's (DIA's) Missile and Space Intelligence Center (MSIC) he is leading a project to reduce aerodynamics characterizations from weeks to days using general-purpose graphics processing unit technologies.

Materials Science: Advancing the Next Revolution of “Stuff”

For millennia, materials have mattered—so much so that entire eras have been named for them. From the Stone Age to the Bronze Age to the Iron Age and beyond, breakthroughs in materials have defined what was technologically possible and fueled revolutions in fields as diverse as electronics, construction and medicine. Today, DARPA is pursuing the next big advances in this fundamentally important domain. Harnessing radical new tools—from ultrafast laser imagers to groundbreaking chemical synthesis approaches—DARPA’s Defense Sciences Office (DSO) is aggressively pursuing the development of novel materials with the potential to boost national security.

“DSO helped launch the modern discipline of materials science and engineering, in part by supporting the first materials-focused interdisciplinary laboratories in the late 1960s and early 1970s,” said DSO Director Stefanie Tompkins. “Since then we’ve stayed at the forefront of the materials revolution, funding seminal work in materials for platforms as diverse as integrated circuits, space-based telescopes, and jet engines. Now, we are moving into an entirely new space, where materials are constructed from atoms on up, to have completely unheard of combinations of properties.”

AF Lab Investigating Microscopic Crack Formations, Metal Fatigue

The B-52 Stratofortress is one of the oldest legacy aircraft in the Air Force. Since the 1950s, the B-52 has led the force in its dominance as the world’s best; however, just as humans begin to age, so do aircraft. Repeated loading and unloading, changes in air pressure, exposure to altitude and more, contribute to

Army Developing Safer, Extended Range Rocket-assisted Artillery Round

The Army is developing a new 155 mm artillery round that will extend cannon range to more than 24 miles (40km), with the added benefits of greater safety for service members and the ability to deliver near-precision strike capability. The XM1113 Insensitive Munition High Explosive Rocket Assisted Projectile, or XM1113 RAP, will replace the aging

Army Tests Manned-unmanned Teaming Capabilities in Pacific Initiative

MARINE CORPS TRAINING AREA BELLOWS, Hawaii — As the U.S. Army shrinks in size, military planners continue to assess strategic options to rapidly build and project effective combat power where needed. The Army anticipates that unmanned capabilities will augment combat formations and, in complex and contested conditions, enable decisive action in unified land operations. The

BE Meyers to Support USMC’s Ocular Interruption Programme

BE Meyers has been selected by the US Marine Corps (USMC) Systems Command (MARCORSYSCOM) to serve as the sole source provider for the Ocular Interruption (OI) programme. The Ocular Interruption system will provide a weapons-mounted or hand-held dazzling laser employed during Escalation of Force (EoF) situations. It is set to replace the Glare Mout 532P-M

Carbon Nanotube-Based Sensor Detects Toxins With a Mobile Phone

A little over four years ago, researchers at the University of California, Riverside, developed a sensor made from carbon nantoubes for detecting toxic chemicals. So enthusiastic were the researchers with the prospects of their technology that they launched a company, Nano Engineered Applications, that intends to add this sensor to people’s mobile phones. While the

Defects, Electrons, and a Long-Standing Controversy

Faster, more energy-efficient electronics could be created with topological insulators, which carry an electrical charge on just the surface, while the interior acts as an insulator. Scientists are delving into how the material”s structure and chemistry correlate with its unusual electronic properties. By carefully controlling and monitoring chemical changes in the topological insulator bulk samarium

Flying with the Fourth State of Matter

A scaled-down gale blows over a flat plate set inside the tabletop wind tunnel. Despite the low lighting and hazy Plexiglas view portals, we can clearly see the frenzied fluttering of streamer ribbons, called telltales, in the field of little wind vanes that carpets the exposed test surface inside. At first, each unruly telltale flies

Iodine-Compatible Hall Effect Thruster

The Hall effect thruster (HET) was designed for long-duration operation with gaseous iodine as the propellant. Iodine is an alternative to the state-of-the-art propellant xenon. Compared to xenon, iodine stores as a solid at much higher density and at a much lower pressure. Because iodine is a halogen, it is reactive with some of the
