1. 1. Synthesis of framework porous sorbents using sustainable precursors

   University essay from Uppsala universitet/Nanoteknologi och funktionella material

   Author : Oskar Hellman; [2021]
   Keywords : Metal organic framework; green synthesis; carbon capture; gas adsorption;

   Abstract : Metal organic frameworks (MOFs) is a quite recently discovered porous material group which shows potential in many different areas. One of these areas is carbon capture; the framework structure of the porous materials allows gas molecules to adsorb to the surface of the pores. READ MORE

3. 2. Methods to create compressive stress in high strength steel components

   University essay from

   Author : Amir Abdin; Kaveh Feyzabi; Oskar Hellman; Henrietta Nordström; Dilman Rasa; Gustav Thaung Tolförs; Per-Olof Öqvist; [2018]
   Keywords : residual compressive stress; high strength steel; methods of inducing stress; analyzing stress;

   Abstract : Residual compressive stresses can be used to increase the lifetime of parts under cyclic stress as they negate the applied tensile stresses that cause crack initiation and propagation in the material. The goal of this project was to investigate methods to induce stresses, their advantages and disadvantages as well as depth and magnitude of induced stresses, and also to find methods of analyzing the induced residual stresses.
