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

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Rickard Gauffin; [2022]
   Nyckelord :XPS; HAXPES; IMFP; Polymer;

   Sammanfattning : 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. LÄS MER

3. 2. Improved Magnetic Beads for Large Scale Separation of Biomolecules

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Rickard Gauffin; Gustav Halldén; Martin Hansén; Anuprya Rattan; Christopher Thulin; Jacob Östholm; [2020]
   Nyckelord :bioprocessing magnetic beads separation nanoparticle;

   Sammanfattning : Two possible ways for increasing the rate of separation for magnetic bead separation has been observed. Increasing NP concentration by 2.5x gave a slight increase in rate of separation while 1.5x and 2. LÄS MER
