Iqhaza Lezinto Ezingavamile Zomhlaba kuma-Catalysts
Kule minyaka engu-50 edlule, kuye kwenziwa ucwaningo olunzulu mayelana nemiphumela ye-catalytic yezinto ezingavamile (ikakhulukazi ama-oxides nama-chloride), futhi eminye imiphumela evamile iye yatholakala, engafinyezwa kanje: 1. Esakhiweni se-elekthronikhi sezinto ezingavamile zomhlaba , ama-electron angu-4f akhona...Funda kabanzi -
