1. 1. Nitride Thin Films for Thermoelectric Applications : Synthesis, Characterization and Theoretical Predictions

   Författare :Mohammad Amin Gharavi; Per Eklund; Rickard Armiento; Björn Alling; Camille Pallier; Caterina Zanella; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Thermoelectrics is the reversible process which transforms a temperature gradient across a material into an external voltage through a phenomenon known as the Seebeck effect. This has resulted in niche applications such as solid-state cooling for electronic and optoelectronic devices which exclude the need for a coolant or any moving parts and long-lasting, maintenance-free radioisotope thermoelectric generators used for deep-space exploration.

3. 2. High Temperature Corrosion in Fluidised Bed Environment

   Författare :Anna Nafari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFB; coatings; Ni and iron based alloys; HCl; SO2; loop seal; High temperature corrosion; erosion corrosion test rig; surface characterization and temperature gradient;

   Sammanfattning : Successful material selection for power plants is the result of understanding the environment in each boiler. The boiler environment is affected by fuel chemistry, co-firing, process control and deposits as well as boiler type, design, size and load. LÄS MER

4. 3. Synthesis and Characterization of High Entropy Alloy and Coating

   Författare :Sajid Alvi; Farid Akhtar; Marta-Lena Antti; Don Seo; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

   Sammanfattning : High entropy alloys (HEAs) are a new class of alloys that contains five or more principal elements in equiatomic or near-equiatomic proportional ratio. The configuration entropy in the HEAs tends to stabilize the solid solution formation, such as body-centered-cubic (BCC), face-centered-cubic (FCC) and/or hexagonal-closed-pack (HCP) solid solution.

5. 4. Engineered Nanostructures and Thermoelectric Nanomaterials

   Författare :Muhammet S. Toprak; KTH; []
   Nyckelord :Nanoengineering; Thermoelectric materials; Chemical Alloying; Skutterudite;

   Sammanfattning : This thesis deals with novel aspects of Nanomaterials,Nanoscience and Nanotechnology. On the materials side, novelmethods were developed for the fabrication of nano-sizedbuilding blocks, such as nanoparticles, nanorods and nanowireswith defined structures and high homogeneity. Nanoparticleswere consolidated to nanostructured materials. LÄS MER

7. 5. The self-spreading double bilayer/Advances in lipid membrane nanotechnology

   Författare :Irep Gözen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; pore; lipid double bilayer; rupture; crackling noise; tension; self-spreading; vesicle; flat giant unilamellar vesicle; viscous fingering.;

   Sammanfattning : In my thesis I describe the generation, characterization and uses of self-spreading double bilayers. This new type of solid-supported model membrane combines features and properties of the 2D lipid bilayer membrane, and the 3D phospholiposome. The double bilayer membrane, i.e. LÄS MER
