Web3.1 Synthesis of metal clusters and diagnostics in the droplet beam Helium droplets are generated in a supersonic expansion of high pressure helium gas through a cold nozzle. Conditions for clustering of helium atoms range typically from 10 to 20 K nozzle temperature and 20 to 80 bar pressure before expansion. In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis) is the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, H, having a single proton as a nucleus) during the early phases of the Universe. Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the Big Bang, and is calculated to be responsible fo…

Synthesis gas (syngas) production is the cornerstone of many industries. This H2 /CO mixture is mainly produced from gasification (coal, heavy hydrocarbons) or reforming (light hydrocarbons). Steam, oxygen, carbon dioxide or mixtures of them act as reforming agents and react with the carbon source at high temperatures. WebProcessing methods include collection of helium as well as compression, drying and storage at high pressure. For helium recovery, Linde Kryotechnik supplies individual components (e.g. gas balloons, high-pressure compressors, filters for oil removal, driers, gas cylinders or high-pressure vessels for storage) or complete systems (from ... government in roman republic
