Mechanical forces are crucial to essentially every cellular activity including intracellular transportation, cell division and differentiation, cell-cell interaction and cell death. The quantification ...

The measurement of aerodynamic forces in shock tunnels is a critical area in high-speed aerodynamics research. In these facilities, short-duration, high-enthalpy flows pose unique challenges that ...

Groundbreaking research has revealed a new way to measure incredibly minute forces at the nanoscale in water, pushing the boundaries of what scientists know about the microscopic world. The ...

(a) The system consisted of six parts as follows: (1) a force transducer; (2) a BAP; (3) a fixture; (4) a high-speed camera; (5) a pool; and (6) a data acquisition system. (b) Photo of the BAP. (c) ...

The new technique, involving a super-resolved photonic force microscope (SRPFM), is capable of detecting forces in water as small as 108.2 attonewtons – a scale so minute that it compares to measuring ...

A groundbreaking study published in Nature Photonics by researchers from Beihang University in China, RMIT University, and other leading institutions, such as the Australian National University and ...

What is a Surface Force Apparatus (SFA)? The Surface Force Apparatus (SFA) is a highly sensitive scientific instrument used to measure the forces between two surfaces at the nanoscale. It allows ...
