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 ...

• 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 ...

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 ...

New research by NIST and Georgetown scientists deciphers the mechanisms that cause the materials to switch between liquid and solid in response to stress. Oobleck's name is borrowed from a Dr. Seuss ...
