(Nanowerk News) Proteins are often considered as molecular machines. To understand how they work, it is not enough to visualize the involved proteins under the microscope. Wherever machines are at ...

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.

(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 ...

For example, a 2-kN force properly applied to a cubic-centimetersized quartz crystal produces over 12.5 kV. Voltage created by an applied stress is called piezoelectricity. Unlike strain gages that ...
