1. 1. Influence of Post-treatments on Corrosion Properties of 3D printed Metal Components for Bioprocessing Applications

   University essay from KTH/Materialvetenskap

   Author : Leyla Koort; [2023]
   Keywords : PBF-LB 316L; surface post-treatments; as-built; tumbling; Hirtisation; DLyte; electropolishing; chemical milling; pitting corrosion; CPT; cyclic potentiodynamic polarisation curves; immersion test in 1M NaCl and 1M NaOH;

   Abstract : Additive manufacturing (AM) has the potential to overtake the conventional production of pipe systems of stainless steel grade 316L intended for bioprocessing applications by utilising powder bed fusion laser beam (PBF-LB) technologies. However, challenges such as high surface roughness need to be overcome and corrosion properties improved to meet industry standards. READ MORE

3. 2. Polarisation-resolved super-resolution microscopy

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Wouter Duverger; [2021]
   Keywords : biophysics; microscopy; super-resolution microscopy; polarisation microscopy; STED; Physics and Astronomy;

   Abstract : This project aims to implement polarisation microscopy on the Tegenfeldt STED (stimulated emission depletion) microscope. STED microscopy is a targeted optical super-resolution method that can attain sub-diffraction resolution using visible light. READ MORE

4. 3. Electro-optical characterization of NanoWire Solarcells

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Ida Ångbäck; [2016]
   Keywords : Solarcell; nanowire; angular dependence; photocurrent; photocurrent microscopy; Technology and Engineering;

   Abstract : A sample with five Nanowire Solar Cell (NWSC) devices of equal design were performance evaluated by characterizing the current spatially and by investigating the angular and polarization dependence. For spatial characterization a Scanning Photocurrent Microscopy (SPCM) setup was developed using a highly focused laser which is scanned across the device as the photocurrent is measured. READ MORE

5. 4. Hydrogen-assisted stress corrosion cracking of high strength steel

   University essay from KTH/Materialvetenskap

   Author : Rohollah Ghasemi; [2011]
   Keywords : Hydrogen assisted stress corrosion cracking; Hydrogen embrittlement; High strength steel; Slow Strain Rate Test;

   Abstract : In this work, Slow Strain Rate Test (SSRT) testing, Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM) were used to study the effect of microstructure, corrosive environments and cathodic polarisation on stress corrosion cracking (SCC) of two grades of high strength steels, Type A and Type B. Type A is manufactured by quench and tempered (Q&T) method. READ MORE

6. 5. Hydrogen-assisted stress corrosion cracking of high strength steel

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Rohollah Ghasemi; [2011]
   Keywords : Hydrogen embrittlement; hydrogen induced cracking; stress corrosion cracking; high strength steel; uniform corrosion; SSRT; hydrogen charging; fractography; hydrogen degradation;

   Abstract : In this work, Slow Strain Rate Test (SSRT) testing, Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM) were used to study the effect of micro-structure, corrosive environments and cathodic polarisation on stress corrosion cracking (SCC) of two grades of high strength steels, Type A and Type B. Type A is manufactured by quench and tempered (Q&T) method. READ MORE
