Cryogenics e sebelisetsoa eng thutong ea likokoana - hloko?
Context:Nuclear magnetic resonance (NMR) ke e 'ngoe ea mekhoa e tloaelehileng haholo ea ho fumana litšobotsi tsa' mele le tsa lik'hemik'hale tsa liathomo ka ho lemoha maqhubu a seea-le-moea a amohelehileng le phomolo e latelang ea li-nucleus lebaleng la makenete. Ena ke e 'ngoe ea mekhoa ea ho khetholla e sebelisoang haholo' me e sebelisoa masimong a mangata. Haholo-holo, matla a khoheli a hlahisoa ke li - electromagnet tse pholileng haholo, le hoja ho e - na le li - spectrometer tse sa hlokeng li - cryogen. Li-solenoid tsa moetlo tse tsamaisang haholo, helium ea mokelikeli e sebelisetsoa ho pholisa li-coil tse ka hare hobane e na le ntlha ea ho belisa e ka bang 4 K khatello ea tikoloho. Li-superconductor tse theko e tlaase tsa tšepe li ka sebelisoa bakeng sa ho kenya li-coil. Lintho tseo ho thoeng ke metsoako e futhumatsang haholo e ka etsoa hore e be e futhumatsang haholo ka tšebeliso ea naetrojene e metsi, e belang hoo e ka bang ka 77 K. Magnetic resonance imaging (MRI) ke mokhoa o rarahaneng oa ho sebelisa NMR moo geometry ea li-resonance e hlakoloang'me e sebelisetsoa ho nka litšoantšo ka ho lemoha boikhathollo ba li-proton tse ferekantsoeng ke pulse ea maqhubu a seea-le-moea tšimong e matla ea makenete. Hangata sena se sebelisoa litabeng tsa bophelo bo botle. Metseng e meholo, ho thata ho fetisa motlakase ka lik'hebole tse holimo, kahoo ho sebelisoa lik'hebole tse ka tlas'a lefatše. Empa likhoele tse ka tlas'a lefatše lia futhumala'me ho hanyetsa ha terata hoa eketseha, ho lebisang tšenyo ea matla. Li-superconductors li ka sebelisoa ho eketsa matla a phallang, le hoja li ne li tla hloka mokelikeli oa cryogenic o kang naetrojene kapa helium ho pholisa likhoele tse khethehileng tse nang le alloy ho eketsa matla a phetisetso. Lithuto tse'maloa tsa ho khoneha li' nile tsa etsoa'me tšimo ena ke taba ea tumellano ka hare ho International Energy Agency.  Koloi e tsamaisang likhase tsa cryogenic lebenkeleng le leholo, Ypsilanti, Michigan Likhase tsa cryogenic li sebelisetsoa ho tsamaisa le ho boloka lijo tse ngata tse hoammeng. Ha lijo tse ngata haholo li lokela ho isoa libakeng tse kang libaka tsa ntoa, libaka tse hlasetsoeng ke tšisinyeho ea lefatše, joalo-joalo, li lokela ho bolokoa nako e telele, kahoo ho sebelisoa mokhoa oa ho hoamisoa ha lijo ka serame. Ho hatsela lijo ka mokhoa oa cryogenic ho boetse hoa thusa liindastering tse khōlō tse sebetsanang le lijo. Lik'hamera tse ngata tsa infrared (tse shebileng ka pele ho infrared) li hloka hore li-detector tsa tsona li pholile ka mokhoa oa cryogenic. Lihlopha tse ling tsa mali tse sa tloaelehang li bolokoa ka mocheso o tlaase, o kang - 165 °C, libankeng tsa mali. Theknoloji ea cryogenics e sebelisang naetrojene e metsi le CO2 e 'nile ea kenngoa lits'ebetsong tsa li-nightclub ho etsa hore ho be le moea o pholileng le moholi o mosoeu o ka khantšoang ka mabone a mebala. Cryogenic tsidifatso e sebediswa ho pholile sesebelisoa ntlha ka nako ya machining ka thulaganyou e difeme. E eketsa bophelo ba sesebelisoa. Oxygen e sebelisetsoa ho phetha mesebetsi e'maloa ea bohlokoa mosebetsing oa ho etsa tšepe. Lirokete tse ngata li sebelisa likhase tsa cryogenic e le mafura. Tsena li akarelletsa oksijene e metsi, hydrogen e metsi le methane e metsi. Ka ho kenya lebili la koloi kapa la teraka ka har'a naetrojene e metsi, rabara e ba thata' me e ka pshatloa hore e be likaroloana tse nyenyane. Likaroloana tsena li ka sebelisoa hape bakeng sa lintho tse ling. Lipatlisiso tsa liteko mabapi le liketsahalo tse itseng tsa fisiks, tse kang li-spintronics le thepa ea magnetotransport, li hloka mocheso oa cryogenic bakeng sa litlamorao tse lokelang ho bonoa. Mefuta e meng ea liente e lokela ho bolokoa ka mocheso oa cryogenic. Mohlala, ente ea Pfizer<unk>BioNTech ea COVID-19 e tlameha ho bolokoa mocheso oa -90 ho isa ho -60 °C (-130 ho isa ho -76 °F). (Bona ketane e batang.)
