SAN ANTONIO — March 6, 2023 —A Southwest Research Institute team has developed a mechanical testing device to analyze fluids and lubricants formulated for electric vehicles. The team modified a ...
What motivated the development of electrified tribological testing for EV lubricants? The global population is expected to exceed 10 billion by 2050, pushing energy demand to more than 900 million ...
If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence of ...

Fluids for classical automatic transmissions, dual-clutch gearboxes (DCT/DSG), and continuously variable transmissions (CVT)
Automatic transmissions have evolved so dramatically over the past decades that today the same term covers fundamentally different mechanisms. A classical hydromechanical automatic transmission, a ...
• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...
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 streams have ...
