The measurement of mechanical behavior in very small samples whose dimensions are on the order of microns and below can offer advantages over conventional macroscopic testing in many instances. Motivations for investigating...

To further develop semiconductor technology, the field of molecular electronics is seeking to manufacture circuit components from individual molecules instead of silicon. Because of...

The objective of this effort was to design, fabricate, integrate, and fly a nuclear thermal rocket without having to build massive ground test facilities. Furthermore, this nuclear rocket...

Warfighters and law enforcement personnel encounter many situations where they need to assess and determine if a situation is hostile or benign. Currently available field explosive detection kits are...

The Army uses robots that are structurally rigid, making them impractical when performing military operations in highly congested and contested urban environments where covert maneuvering is critical...

The challenge of miniaturizing devices and systems is also achieving a broader dynamic range of detection for small signals such as sound, vibration, and radio...

Capturing carbon dioxide (CO₂) and converting it to useful chemicals such as methanol could reduce both pollution and U.S. dependence on petroleum products. Catalysts are used to bring...

Over the past few years, deep learning algorithms have proven to be highly successful in solving complex cognitive tasks such as controlling self-driving cars and language...

Fabrics that resist water are essential for everything from rainwear to military tents, but conventional water-repellent coatings have been shown to persist in the environment and accumulate in our...

Artificial intelligence (AI) has been used to teach wireless devices to sense people's postures and movement, even from the other side of a wall. RF-Pose uses a neural network to analyze...
