Kwindawo ye-frank herbert spacera "Iindunduma", into exabisekileyo yendalo ebizwa ngokuba yi "Poux Umxube" ENTUTAL "ENOBANTU" ENYE Abantu bafumana abantu bephela beyokuseka impucuko enkulu. Kubomi bokwenyani emhlabeni, iqela leentsimbi zendalo ezibizwa ngokuba zizinto ezinqabileyo zomhlaba zenze ukuba kwenziwe itekhnoloji yale mihla. Ibango lezi zinto ziphambili phantse kuzo zonke iimveliso ze-elektroniki zangoku zinyuka kabukhali.
Umhlaba onqabileyodibana amawakawaka eemfuno ezahlukeneyo-umzekelo, i-cerium isetyenziswa njengeyona nto ibaluleke kakhulu kwioyile ehlaziyiweyo, ngelixaIGadiliniumI-fasts neutrons kwi-nuclear reactors. Kodwa olona luntu lubalulekileyo lwezi zinto lulele kwi-LUMNECANCOCE NOBUCHULE.
Sixhomekeke kumhlaba onqabileyo ukuba ufake umbala kwiscreen sefowuni yethu, sebenzisa i-fluorescence ukubonisa ubunyani be-euro ye-euro, kunye nokudlulisela imiqondiso elwandle ngentambo. Ziyimfuneko ukwenza izinto ezithile ezomeleleyo nezinokuthenjwa emhlabeni. Bavelisa amaza esandi entloko, ukuphucula ulwazi lwedijithali kwindawo, kwaye utshintsha umkhondo we-thermal yokukhangela. Umhlaba onqabileyo ukhulisa nokuphuhliswa kwetekhnoloji eluhlaza, njengamandla omoya kunye nezithuthi zombane, kwaye unokuveza izinto ezintsha zekhompyuter. UStephen Boyd, umkhenkce wekhemistli kunye nomcebisi ozimeleyo, wathi, "Olu luhlu alunasiphelo. Ziphi na
Umhlaba onqabileyo ubhekisa kwi-lanthanide lutitium kunye nezinto ezili-14 phakathi kweLanthanum kwayeyttrium, ehlala yenzeka kwidipozithi enye kwaye ineepropathi zeekhemikhali ezifana neLanthide. Ezi ngwevu ezingwevu kwi-stalties ezinemibala ebomvu zihlala zineeplastiki kunye neendawo ezinqabileyo kunye nezithambisi ezibi. Amandla abo afihlakeleyo alele kwii-elektroni zabo. Zonke ii-atom zine-nucleus ejikelezwe zii-elektroni, ezihlala kwindawo ebizwa ngokuba yi-orbit. I-elektroni kwi-orbit ekude kakhulu kwi-nucleus yi-Eleclence Electroni, ethatha inxaxheba ekuphenduleni kweekhemikhali kunye neebhondi ze-atom.
Uninzi lweLanthide lunelinye iqela elibalulekileyo le-elektroni, elibizwa ngokuba yi "F-elektroni", ezihlala kumda weGolide kufutshane ne-valenten kodwa isondele kakhulu kwi-nucleus. I-ANA Dettencourt Dias, i-Inorganic Chemist kwiDyunivesithi yaseNevada, Reno, yathi: "Yizo ezi zinto zezinto ezibangela ibala lezinto ezinqabileyo kunye ne-luminescec."
I-Lits Eards liqela lezinto ezili-17 (eziboniswe luhlaza okwesibhakabhaka kwitafile yexesha). Iseti esezantsi yomhlaba onqabileyo ibizwa ngokuba yi-lanthanide (I-Luttium, Lu, dibanisa nomgca wentlokoi-lanthanum, LA). Into nganye iqulethe iqokobhe, idla ngokuba ne-elektroni, eyenza ezi zinto zinezinto zemagneti kunye nezikhangeli.
