1. 1. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines

   Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :Michelle Dossey; [2023]
   Nyckelord :PGM; PGE; laterite; limonite; chromitite; dunite; platinum group minerals; platinum group elements; Acoje; Philippines;

   Sammanfattning : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. LÄS MER

3. 2. Hur bildades Bushveldkomplexet?

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Filip Ivarsson; [2015]
   Nyckelord :chromite; intrusion; platinum; LIP; Bushveld Complex; Earth and Environmental Sciences;

   Sammanfattning : The Bushveld complex is the world’s largest mafic intrusion and located on the Archean Kaapvaal craton, southern Africa. The complex’s host rock has anomalous quantities of platinum-group elements (PGE), chromite and other valuable metals of high demand. LÄS MER

4. 3. A Study of the Memristor Models and Applications

   Master-uppsats, Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

   Författare :Vahid Keshmiri; [2014]
   Nyckelord :Memristor; modeling;

   Sammanfattning : Before 1971, all the electronics were based on three basic circuit elements. Until a professor from UCBerkeley reasoned that another basic circuit element exists, which he called memristor; characterized bythe relationship between the charge and the flux-linkage. A memristor is essentially a resistor withmemory. LÄS MER
