The U.S. Air Force is testing layered counter-drone defenses through dedicated experimental facilities, moving away from the ...

Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution is needed for a wide range of ...

Government contracts awarded by Air Force Research Lab have since been an effective collaboration between the government and private sectors. The purpose of these research and development programs is ...

(A) The structure of a CNT. (B) A typical structure of 2D materials. (C) The unique structure of a silicon nanoladder. Due to limitations in the performance of traditional materials, force sensors ...

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...

Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.
