  1. 1. Investigation on the effect of pore size and surface area of mesoporous silica on the conductivity of solid composite electrolytes

    University essay from KTH/Tillämpad fysik

    Author : Hitesh Khanna Pedaprolu; [2022]
    Keywords : Solid Composite Electrolytes SCE ; Mesoporous Silica; Silica SiO2 ; Ionic Liquid Electrolyte ILE ; Fasta sammansatta elektrolyter SCE ; mesoporös kiseldioxid; kiseldioxid SiO2 ; jonisk flytande elektrolyt ILE ;

    Abstract : Solid-state batteries are gaining a lot of attention in the commecial sector today. Development of the solid state electrolytes is an important part in making commercially viable solid-state batteries. READ MORE

  3. 2. Determination of the inelastic mean freepath for SiO2 and the BBL polymer : A study with XPS and HAXPES

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Rickard Gauffin; [2022]
    Keywords : XPS; HAXPES; IMFP; Polymer;

    Abstract : This study targets methodology development using Photoelectron Spectroscopy (PES) as a tool for investigating material surfaces. When analysing samples with X-ray Photoelectron Spectroscopy (XPS) and Hard X-ray Photoelectron Spectroscopy (HAXPES), it is important to know the probing depth of the samples. READ MORE

  4. 3. Polymerized Tubular Silicates in Lower Cambrian Carbonates – Biology or Chemistry?

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Scott Green; [2022]
    Keywords : biosignature; tubular structures; Lower Cambrian; silica precipitation; bifurcating; biosignatur; rörstrukturer; Kambrium Serie 3; kiseldioxid utfällning; förgrening;

    Abstract : Shallow marine environments from the Lower Cambrian period were very different to shallow marine environments of today. Tubes of what was thought to be silica recovered from a partly dolomitized carbonate sample collected form a site near Indian Springs, Nevada could help further understand the chemistry and characteristics of such environments.

  5. 4. Development of a Method to Predict the Adhesion of Industrial Paint Coating

    University essay from KTH/Fiber- och polymerteknologi

    Author : Akheen Sadik; [2022]
    Keywords : Contact angle technique; optical tensiometer; paint coating; adhesion promoter; silane; kontaktvinkel; optisk tensiometer; ytbehandling; adhesion; silan;

    Abstract : I samarbete med Sherwin-Williams AB, utvecklades en metod med kontaktvinkelmätning för att teoretiskt uppskatta vätbarhet och vidhäftningsförmåga av industriella färger på stålsubstrat. Optisk tensiometer och Youngs ekvation kombinerat med OWRK beräkningsmodell användes för att bestämma ytenergier. READ MORE

  6. 5. Investigation of the zinc re-grinding circuit at Boliden Garpenberg

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nils Merum; [2021]
    Keywords : Flotation; re-grinding; Garpenberg; Boliden;

    Abstract : Boliden’s mineral processing plant in Garpenberg wanted to investigate their zinc-regrinding circuit. The re-grinding circuit had performed subpar when running as the total recovery of zinc was lowered and problem with the dewatering of the final concentrates was also noted. Therefore, the zinc re-grinding circuit is currently not being used. READ MORE
