Isici somhlaba esingavamile | I-Terbium (Tb)
Ngo-1843, uKarl G. Mosander waseSweden wathola i-element terbium ngocwaningo lwakhe nge-yttrium earth. Ukusetshenziswa kwe-terbium ikakhulukazi kuhilela izinkambu zobuchwepheshe obuphezulu, okungamaphrojekthi asezingeni eliphezulu nolwazi olunzulu, kanye namaphrojekthi anenzuzo enkulu kwezomnotho...Funda kabanzi -
Isici somhlaba esingavamile | i-gadolinium (Gd)
Ngo-1880, uG.de Marignac waseSwitzerland wahlukanisa i-"samarium" yaba izakhi ezimbili, enye yazo eyaqinisekiswa iSolit ukuthi iyisamarium kanti enye yaqinisekiswa ucwaningo lukaBois Baudelaire. Ngo-1886, u-Marignac waqamba lesi sici esisha ngokuthi i-gadolinium ngokuhlonipha usokhemisi waseDashi u-Ga-do Linium, owathi ...Funda kabanzi -
Izakhi Zomhlaba Ezingavamile | Eu
Ngo-1901, u-Eugene Antole Demarcay wathola into entsha evela ku-"samarium" futhi wayiqamba ngokuthi i-Europium. Lokhu cishe kuqanjwe ngegama elithi Europe. Iningi le-europium oxide lisetshenziselwa izimpushana ze-fluorescent. I-Eu3+ isetshenziswa njenge-activator yama-phosphors abomvu, futhi i-Eu2+ isetshenziselwa ama-phosphors aluhlaza. Okwamanje,...Funda kabanzi -
Isici somhlaba esingavamile | I-Samarium (Sm)
Isici somhlaba esingavamile | I-Samarium (Sm) Ngo-1879, u-Boysbaudley wathola into entsha yomhlaba eyivelakancane ku-"praseodymium neodymium" etholwe ku-niobium yttrium ore, wayiqamba ngokuthi i-samarium ngokwegama lale nsimbi. ISamarium inombala ophuzi okhanyayo futhi iyimpahla eluhlaza yokwenza amaSamari...Funda kabanzi -
Isici somhlaba esingavamile | I-Lanthanum (La)
I-elementi 'i-lanthanum' yaqanjwa ngo-1839 lapho umSweden okuthiwa 'uMossander' ethola ezinye izakhi emhlabathini wedolobha. Uboleke igama lesiGreki elithi 'kufihliwe' ukuze aqambe lesi sici 'lanthanum'. I-Lanthanum isetshenziswa kabanzi, njengezinto zokwakha ze-piezoelectric, izinto ze-electrothermal, i-thermoelec ...Funda kabanzi -
Isici somhlaba esingavamile | I-Neodymium (Nd)
Isici somhlaba esingavamile | I-Neodymium (Nd) Ngokuzalwa kwento ye-praseodymium, i-elementi ye-neodymium nayo yavela. Ukufika kwento ye-neodymium yenze insimu yomhlaba engavamile, yadlala indima ebalulekile emkhakheni womhlaba ongavamile, futhi yalawula imakethe yomhlaba engavamile. I-Neodymium isiphenduke indawo eshisayo...Funda kabanzi -
Izakhi Zomhlaba Ezingavamile | I-Scandium (Sc)
Ngo-1879, oprofesa bamakhemikhali baseSweden u-LF Nilson (1840-1899) kanye no-PT Cleve (1840-1905) bathola into entsha kumaminerali angavamile i-gadolinite kanye negolide elingavamile elimnyama cishe ngesikhathi esifanayo. Baqamba lesi sici ngokuthi "Scandium", okwakuyinto "enjenge-boron" eyabikezelwa uMendeleev. Yabo...Funda kabanzi -
Abacwaningi be-SDSU Ukuklama Amagciwane Akhipha Izinto Ezingavamile Zomhlaba

Amaprotheni asanda kutholwa asekela ukucwengwa okusebenzayo kwe-Rare Earth
Amaprotheni asanda kutholwa asekela ukucwengwa okuphumelelayo komthombo womhlaba ongavamile: izimayini Ephepheni lakamuva elishicilelwe ku-Journal of Biological Chemistry, abacwaningi e-ETH Zurich bachaza ukutholakala kwe-lanpepsy, iphrotheni ehlanganisa ngokuqondile ama-lanthanides - noma izakhi zomhlaba eziyivelakancane - kanye nokucwasa. .Funda kabanzi -
Amaphrojekthi amakhulu okuthuthukiswa komhlaba angavamile ngekota ka-March
Izakhi zomhlaba ezingavamile zivame ukuvela ohlwini lwamaminerali abalulekile, futhi ohulumeni emhlabeni wonke basekela lezi zimpahla njengendaba yentshisekelo yezwe nokuvikela izingozi ezinkulu. Eminyakeni engu-40 edlule yentuthuko yezobuchwepheshe, izakhi zomhlaba ezingavamile (REEs) ziye zaba ingxenye ebalulekile...Funda kabanzi -
