I-CERIUM, Element 58 yetafula lesikhathi.
Umrintshiiyinsimbi emnyama kakhulu yomhlaba, futhi kanye nento etholakele ye-YTtrium Element, ivula umnyango wokuthola okunyeUmhlaba ongavamileizakhi.
Ngo-1803, usosayensi waseJalimane uKlaprott wathola into entsha oxide etsheni elibi eligcwele elikhiqizwa edolobheni elincane laseSweden e-Vastras, elalivutha. Ngasikhathi sinye, osokhemisi baseSweden uBhelilius noHersinger bathola ne-oxide yento efanayo ku-ore. Kuze kube ngu-1875, abantu bathola i-certium yensimbi evela ku-colten cerylium oxide nge-electrolysis.
Imbandi yensimbiiyasebenza kakhulu futhi ingashisa ukwakha i-certium oxisi efudumele. I-Cerium Iron Alloy exutshwe nezinye izinto zomhlaba ezingandile ingakhiqiza izinhlansi ezinhle lapho zihlikihla izinto ezinzima, zithambisa ama-combustible azungezile, futhi kuyinto ebalulekile kumadivayisi wokulahla afana nezibani nama-spark. Izozishisa futhi ngokwayo, ihambisane nezinhlansi ezinhle, i-Iron yengezwa nezinye i-lanthanide, ukuthuthukisa imiphumela yalezi zinhlaka. I-mesh eyenziwe nge-cerium noma efakwe ngosawoti we-cerium ingakhuphula ukusebenza kahle kokuvuselelwa kwamafutha futhi ibe yi-Aid enhle kakhulu yokuvutha, engagcina uphethiloli. I-Cerrium futhi isengezo sengilazi enhle, esingadonsa imisebe ye-ultraviolet nemisebe ye-infrared, futhi isetshenziswa kabanzi endabeni yemoto. Ayikwazi ukuvikela imisebe ye-ultraviolet kuphela, kepha futhi yehlisa izinga lokushisa emotweni, ukonga ugesi ukuze isebenze ngomoya.
Izicelo eziningi ze-CERCIUM zisuselwa ekuguqulweni phakathi kwe-trium cerium ne-tetravalent cere, enezindawo ezihlukile ezihlukile ezindaweni zomhlaba ezingavamile. Lesi sici sivumela i-certium ukuthi igcine ngempumelelo futhi ikhiphe umoya-mpilo, ongasetshenziswa ku-solid oxide uphethiloli esitokisini ukuze i-catalyze redox, ngaleyo ndlela ithole ukunyakaza okuqondayo kwama-elektroni ukuze kwakhiwe ama-elektroni. Ama-zeolites afakwe nge-certium ne-lanthanum angasebenza njengama-catalysts wokuqhekeka kukaphethiloli ngesikhathi senqubo yokucolisa. Ukusetshenziswa kwe-cerrium oxide kanye nezinsimbi eziyigugu kwabaguquli bezimoto eziguquguqukayo bangaguqula amagesi aphekayo angenamkhawulo abe yi-nitrogen yamahhala yokungcolisa, i-carbon dioxide, namanzi, ukuvikela ngempumelelo inani elikhulu lokuphuma kwezimoto. Ngenxa yekhono layo lokudonsa umoya-mpilo, abantu bahlola nokuthi bangazisebenzisa kanjani ama-nanoparticles we-certium oxide e-antioxidant therapy. Uhlelo lwe-laser oluqinile lwe-laser elakhiwe yi-United States liqukethe i-cersium, olungasetshenziselwa ukubona izikhali zebhayoloji ngokubheka ukugxila kwe-tryptophan, futhi nakho kungasetshenziselwa ukutholwa kwezokwelashwa.
Ngenxa yezakhiwo zayo ezihlukile ze-PhotyHyysical, i-cereyusi ibuye ibe yi-catalyst ebaluleke kakhulu, eyenza okushibhileIsiko (iv) oxideethandwa ososayensi emkhakheni wamaCatalysts. NgoJulayi 27, 2018, umagazini weSayensi ushicilele impumelelo enkulu yocwaningo lwesayensi ngeqembu leZuo Zhiwei kusuka esikoleni seShanghaitHest University - ukukhuthaza ukuguqulwa kwe-Methane ngokukhanya. Isihluthulelo senqubo yokuguqulwa ukuthola uhlelo olushibhile futhi olusebenzayo lwe-catalysis oluhlelekile lwe-catalyst kanye ne-catalyst yotshwala, ihlinzeka ngempumelelo isixazululo sesayensi sokuguqula imikhiqizo yamakhemikhali angezelwe, njenge-rocket profelant fuel.
