Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

For example, these so-called non-Newtonian fluids ... the researchers fixed the particles in the holder in order to measure their sliding friction. This friction is many times higher than the ...

The researchers could immediately calculate the coefficients for rolling and sliding friction of the various ... a large fraction of particles, for example, and thus find the best flow properties.

I tested eight of the best hiking boots to see which proved the most comfortable and found two pairs that’ll keep you comfy ...

WASHINGTON] China’s central bank chief Pan Gongsheng urged countries to help maintain confidence in the global economic ...

Misconceptions remain around EV driving. In northern Sweden, I saw just how good they really are in frigid temperatures and even driving across a frozen lake.

The F-150 XLT and its PowerBoost hybrid powertrain are competent around town but ready for anything. The automotive sales charts are in a perpetual state of turmoil. Names come and go—does anyone ...

This micro parameter inevitably establishes the temperature at the tire surface, affecting grip as a consequence. From McLaren’s point of view, engineers have probably found a very good window where ...

China’s economy grew 5.4% in Q1, driven by strong exports ahead of US tariff hikes. Growth is expected to slow as higher ...
