1. 1. Synthesis of aromatic thiol ligands for the formation of thermoelectric materials

   University essay from KTH/Kemi

   Author : Clément Bouchut; [2024]
   Keywords : ligand; organic chemistry; organic synthesis; thermoelectric materials; thiol; ligand; organisk kemi; organisk syntes; termoelektriska material; tiol;

   Abstract : I detta arbete så har en uppsättning aromatiska ditiol-ligander framställts (3,5-dimerkaptobensoesyra I, methyl-3,5-dimerkaptobensoat II, 3,5-dimerkaptotoluen III, 4,6-dimerkaptoisoftalaldehyde IV). En trestegssyntes innehållande Newman-Kwart omlagring som nyckelsteg användes för framställning av föreningarna I-III medan förening IV togs fram via en annan syntesväg. READ MORE

3. 2. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

   University essay from KTH/Tillämpad fysik

   Author : Xinyi Wei; [2023]
   Keywords : Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

   Abstract : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.

4. 3. Fabrication and Evaluation of Sb2Te3/PVDF Hybrid Thermoelectric Films

   University essay from KTH/Tillämpad fysik

   Author : Bo Yu; [2020]
   Keywords : ;

   Abstract : Thermoelectric (TE) materials and devices have been extensively studied for harvesting waste heat energy. There is more interest to fabricate TE materials and devices at low cost and highly-efficient ways. READ MORE

5. 4. Investigation and Evaluation of Pump Types for a Liquid Metal Jet X-Ray Source

   University essay from KTH/Maskinkonstruktion (Avd.)

   Author : Matilda Svensson; [2020]
   Keywords : pumps; pump types; liquid galinstan; metal jet; x-ray source; pumpar; pumptyper; flytande galinstan; metaljetstråle; röntgenkälla;

   Abstract : Since Wilhelm C. Röntgen discovered the x-rays in 1895 little has been done to improve the x-ray technology. In 2003 a group of scientists at KTH Royal Institute of Technology suggested a new type of x-ray source, namely a liquid metal jet x-ray source. The solid anode in the original source was changed to a liquid metal jet anode. READ MORE

6. 5. Design of a Carbon Fiber Thermocouple for Elevated Temperature Measurements

   University essay from KTH/Materialvetenskap

   Author : Marcus Holmström; [2020]
   Keywords : Thermocouple; Carbon Fiber; Thermoelectrical; Electromotive Force; Polyacrylonitrile; Rayon; Termoelement; Kolfiber; Termoelektrisk; Elektromotorisk spänning; Polyacrylonitrile; Viskos;

   Abstract : Thermocouples are one of the most commonly used instruments for thermometry at elevated  temperatures. As of today, there are only a few types of thermocouples that are built to withstand a temperature beyond 1600 °C,however they usually have a temperature measurement uncertainty of around 1% at these high temperatures.
