The pyroelectric effect is also present in bone and tendon. [18] The most important example is gallium nitride, a semiconductor. [19] The large electric fields in this material are detrimental in light emitting diodes (LEDs), but useful for the production of power transistors. [citation needed]
This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive.
A combustion light-gas gun (CLGG) is a projectile weapon that utilizes the explosive force of low molecular-weight combustible gases, such as hydrogen mixed with oxygen, as propellant. When the gases are ignited, they burn, expand and propel the projectile out of the barrel with higher efficiency relative to solid propellant and have achieved ...

An incredible image buried deep in an annual military report released last month shows the U.S. Navy test-firing a high-powered laser weapon at a drone target from one of its warships.. The photo ...
Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
