(Nanowerk News) For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes — pipes with walls that can be just one atom thick. The ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Friction dynamics in wet clutch systems represent a critical field of study in automotive and mechanical engineering, where precise control of heat, torque, and wear processes is essential for optimal ...

Imagine walking from one side of a swimming pool to the other. Each step takes great effort -- that's what makes water aerobics such effective physical exercise. Imagine walking from one side of a ...

This week, physicists at the Division of Fluid Dynamics meeting in Minneapolis, Minnesota, exhibited their best experimental images in a “gallery of fluid motion” Air vortices often form around the ...
