Izinsimbi eziningi nezinhlanganisela zazo kufanele zenziwe zibe amafilimu amancane ngaphambi kokuba asetshenziswe emikhiqizweni yobuchwepheshe efana ne-electronics, izibonisi, ama-fuel cell, noma izinhlelo zokusebenza ze-catalytic.Nokho, izinsimbi “eziqinile” ezihlanganisa izakhi ezinjengeplatinum, iridium, ruthenium, ne-tungsten, kunzima ukuzishintsha zibe amafilimu amancane ngoba amazinga okushisa aphakeme kakhulu (ngokuvamile angaphezu kuka-2 000 degrees Celsius) ayadingeka ukuze ahwamuke.
Imvamisa, ososayensi bahlanganisa lawa mafilimu ensimbi besebenzisa izindlela ezinjengokufafaza nokuhwamuka kwe-electron beam.Lokhu kokugcina kuhilela ukuncibilika nokuhwamuka kwensimbi emazingeni okushisa aphezulu kanye nokwakheka kwefilimu elincanyana phezu kwepuleti.Nokho, le ndlela yendabuko iyabiza, idla amandla amaningi, futhi ingase ingaphephile ngenxa yamandla kagesi aphezulu asetshenziswayo.
Lezi zinsimbi zisetshenziselwa ukwenza imikhiqizo eminingi, kusukela kuma-semiconductors ukuze kusetshenziswe izinhlelo zokusebenza zekhompyutha ukubonisa ubuchwepheshe.I-Platinum, isibonelo, iphinde ibe yinto ebalulekile yokuguqulwa kwamandla kanye ne-catalyst yokugcina futhi icatshangelwa ukusetshenziswa kumadivayisi we-spintronics.
