    It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.

    At the time of her sinking, Central America carried gold then valued at approximately US$8,000,000 (2021 value of $765 million, based on a gold price of $1,738.70 per troy ounce = $56,087 per kg). The valuation of the ship itself was substantially more than those lost in other disasters of the period, being $140,000 (equivalent to $4,720,000 in ...

  4. Vapor-compression evaporation - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_evaporation

    A compression ratio of 2 is possible (and sometimes more) but unless the motive steam is at a reasonably high pressure (say, 16 bar g - 250 psig - or more), the motive steam consumption will be in the range of 2 kg per kg of suction vapors. A higher compression ratio means a smaller heat exchanger, and a reduced investment cost.

    Each kilogram of the fission products of 235 U will contain 63.44 grams of ruthenium isotopes with halflives longer than a day. Since a typical used nuclear fuel contains about 3% fission products, one ton of used fuel will contain about 1.9 kg of ruthenium. The 103 Ru and 106 Ru will render the fission ruthenium very radioactive.
