  2. National Ignition Facility - Wikipedia

    en.wikipedia.org/wiki/National_Ignition_Facility

    NIF hosts the world's most energetic laser, which indirectly heats the outer layer of a small sphere. The energy is so intense that it causes the sphere to implode, squeezing the fuel inside. The implosion reaches a peak speed of 350 km/s (0.35 mm/ns), [5] raising the fuel density from about that of water to about 100 times that of lead.

  5. Ultrapure water - Wikipedia

    en.wikipedia.org/wiki/Ultrapure_water

    Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including organic and inorganic compounds, dissolved and particulate matter, and ...

  6. Energy factor - Wikipedia

    en.wikipedia.org/wiki/Energy_factor

    The energy factor metric only applies to residential water heaters, which are currently defined by fuel, type, and input capacity. [5] Generally, the EF number represents the thermal efficiency of the water heater as a percentage, since it is an average of the ratio of the theoretical heat required to raise the temperature of water drawn to the amount of energy actually consumed by the water ...

  7. Fusion energy gain factor - Wikipedia

    en.wikipedia.org/wiki/Fusion_energy_gain_factor

    The explosion of the Ivy Mike hydrogen bomb. The hydrogen bomb was the first device able to achieve fusion energy gain factor significantly larger than 1.. A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state.

  8. Nickel(II) nitrate - Wikipedia

    en.wikipedia.org/wiki/Nickel(II)_nitrate

    Nickel nitrate is the inorganic compound Ni(NO 3) 2 or any hydrate thereof. In the hexahydrate, the nitrate anions are not bonded to nickel. Other hydrates have also been reported: Ni(NO 3) 2. 9H 2 O, Ni(NO 3) 2. 4H 2 O, and Ni(NO 3) 2. 2H 2 O. [3]

  9. Fresh water - Wikipedia

    en.wikipedia.org/wiki/Fresh_water

    Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to
