2. 1. Solution based methods for synthesis of tin and zinc; wires and thin films

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

   Författare :Sofie Johansson; [2012]
   Nyckelord :solution based chemistry; sol-gel; nanowires; solar cells;

   Sammanfattning : In this work two different solution based methods have been used for synthesis ofoxide-wires and homogeneous heterometallic oxides of transparent conductingmaterials.The first method used is an aqueous chemical growth (ACG) method for synthesis ofmicrorods and nanowires of zinc oxide and tin dioxide useful for detection of toxicgases.

4. 2. Development of accelerated corrosion tests involving alternative exposure to hostile gases, neutral salt spray and drying

   Master-uppsats, Chalmers tekniska högskola/Institutionen för kemi- och bioteknik

   Författare :Erika Callsen; [2012]
   Nyckelord :;

   Sammanfattning : In this thesis, a well proven corrosion testing method developed by SP Technical Research Institute of Sweden (SP) ISO 21207 method B is modified in order to increase even further the acceleration factor of corrosion attacks by 40%. The method combines humidity cycling with conditioning, drying as well exposure to corrosive substances SO2, NO2 and NaCl solution. LÄS MER

5. 3. Personality in piglets : Is there a difference in personality traits between pigs from different teat order positions?

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Ann-Sofie Sundman; [2011]
   Nyckelord :Pig; Personality; Teat order; Behavioural observations; Novel object test;

   Sammanfattning : The objective of this study was to determine whether piglets from different positions in the teat order differ inpersonality. Teat order is established within the first days after birth and from that time, piglets basically suckle fromthe same teat pair until weaning. LÄS MER

6. 4. Measurement of internal current densities during a HiPIMS discharge with a Rogowski coil

   Magister-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Magnus Karlsson; [2011]
   Nyckelord :HiPIMS; HPPMS; plasma; electron transport; Rogowski coil;

   Sammanfattning : In this study, the current densities in three different directions (r, φ and z) have been measured above the target during a HiPIMS discharge by the use of a Rogowski coil. This was done to examine the key transport parameter Jφ/JD┴ = ωge TEFF throughout the whole measured area, which is a key parameter describing how electrons are transported across magnetic field lines.

7. 5. Method development for identification of N-linked glycans by high performance anion exchange chromatography with pulsed amperometric detection and time of flight mass spectrometry

   M1-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Johanna Alm; [2011]
   Nyckelord :N-linked glycans; HPAEC-PAD; desalting glycans; TOF;

   Sammanfattning : In the biopharmaceutical industry, identification of glycans in a glycoprotein is a regulatory requirement and is a part of the characterization of the protein. Glycans are constructed of several monosaccharides linked together. N-linked glycans, which have been studied in this project, are attached to the nitrogen atom in asparagine. LÄS MER
