hν, light, in chemistry shorthand. Vickers Hardness, a hardness test. What does equation E hv mean? E = hv C= λv. E is the energy of the light in Joules (J), h is a constant which is 6.626 X 10-34 J·s, and. v is the frequency of the light in s-1 or waves/s (also...

Using polymers, such as PEEK (poly-ether-ether-ketone), in the outer layer introduces a built-in lubricant coating that reduces friction and wear. High Strain Tolerance High hardness alone does not necessarily provide comprehensive wear resistance capabilities. Compliance is also a very valuable prop...
CZ doesn’t its also clear in colour which most diamonds aren’t, but they can be coloured by adding metal oxides in the production process. Unlike diamonds CZ are good thermal insulators which mean they become warm but can’t withstand the same kind of heat a diamond can, which is...

The main quantities regarded in this study are the RMS values in each direction and the RMS VTV (root mean square vibration total value), which is defined as the square root of the sum of squares of the RMS values in the three measuring directions, i.e., the following: 𝑎hv=𝑎2h...
