A Sea Rogue remote weapon system fitted with a 12.7 mm machine gun mounted on a Valour class frigate of the South African Navy. The Reutech Rogue remote weapon system is a remotely controlled turret system for weapons ranging from 7.62 mm general purpose machine guns up to 20 mm cannons or a 40mm automatic grenade launcher.
A DIME weapon consists of a carbon fiber casing filled with a mixture of explosive and very dense microshrapnel, consisting of very small particles (1–2 mm) or powder of a heavy metal. To date, tungsten alloy (heavy metal tungsten alloy, or HMTA) composed of tungsten and other metals such as cobalt and nickel or iron has been the preferred ...
Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...
Cryogenic fuels are fuels that require storage at extremely low temperatures in order to maintain them in a liquid state. These fuels are used in machinery that operates in space (e.g. rockets and satellites) where ordinary fuel cannot be used, due to the very low temperatures often encountered in space, and the absence of an environment that supports combustion (on Earth, oxygen is abundant ...

In the classic dilution refrigerator (known as a wet dilution refrigerator), the 3 He is precooled and purified by liquid nitrogen at 77 K and a 4 He bath at 4.2 K. Next, the 3 He enters a vacuum chamber where it is further cooled to a temperature of 1.2–1.5 K by the 1 K bath , a vacuum-pumped 4 He bath (as decreasing the pressure of the ...

A small (7 x 5.75 x 11.5”) 45 MHz spectrometer with good resolution (< 1.8 Hz) and mid-to-low-range sensitivity that weighs 4.76 kg (10.5 lbs) and can acquire a 1D 1H or 19F spectra. PicoSpin was acquired by Thermo Fisher Scientific in December 2012, and subsequently renamed the product Thermo Scientific picoSpin 45. [ 23 ]
