1. 16. Dynamics of biological membranes and associated water

   Författare :Peter Berntsen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dielectric spectroscopy; phase transition; glass transition; DSC; lipid bilayers; lipid dynamics; water dynamics; purple membrane; diffusion; polarisation; QENS.; relaxation; long-range conductivity;

   Sammanfattning : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. LÄS MER

3. 17. Effects of surfactant adjuvants on plant leaf cuticle barrier properties

   Författare :Anton Fagerström; Malmö högskola; []
   Nyckelord :Adjuvant; Surfacant; Cuticle; Tebuconazole; Diffusion; Clivia miniata Regel leaf; Model wax; Phase diagram; Hydration; Eutectic melting; Crystalline domains; Softening; Wax film; Quartz Crystal Microbalance with dissipation QCM-D ; Differential Scanning Calorimetry DSC ; Small- and Wide-angle X-ray Diffraction SWAXD ;

   Sammanfattning : I avhandlingen undersöks växelverkan mellan det yttersta lagret på växters blad (cutikeln), aktiva substanser, och ämnen som tillsätts för att öka bekämpningsmedlens effekt, i detta fall vissa former av tensider. Barriären som hindrar upptag av främmande ämnen i växten sitter i cutikeln. LÄS MER

4. 18. Microstructure and Inclusion Characteristics in Steels with Ti-oxide and TiN Additions

   Författare :Wangzhong Mu; Pär Jönsson; Keiji Nakajima; Casper Van der Eijk; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intragranular ferrite; oxide metallurgy; inclusion engineering; titanium nitride; titanium oxide; inclusion size; heterogeneous nucleation; critical diameter; confocal laser scanning microscopy CLSM ; differential scanning calorimetry DSC ; continuous cooling transformation CCT diagram.; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : Non-metallic inclusions in steels are generally considered to be detrimental for mechanical properties. However, it has been recognized that certain inclusions, such as Ti-oxide and TiN, can serve as potent nucleation sites for the formation of intragranular ferrite (IGF) in low-alloy steels. LÄS MER

5. 19. Prussian blue analogue copper hexacyanoferrate : Synthesis, structure characterization and its applications as battery electrode and CO2 adsorbent

   Författare :Dickson Odhiambo Ojwang; Gunnar Svensson; Jekabs Grins; Andrew Goodwin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; copper hexacyanoferrate; synthesis; structure refinement; thermal dehydration; CO2 adsorption; kinetic analysis; in operando synchrotron X-ray diffraction; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Prussian blue (PB) and Prussian blue analogues (PBAs) are compounds with potential applications in a large variety of fields such as gas storage, poison antidotes, electrochromism, electrochemistry and molecular magnets. The compounds are easy to synthesize, cheap, environmentally friendly and have been pursued for both fundamental research and industrial purposes. LÄS MER

7. 20. Microstructural Development of Nanocrystalline Ni- and Co-Based Materilas upon Annealing

   Författare :Melina da Silva; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ni; grain growth; nanocrystalline materials; Co-P; Ni-Fe; thermal stability; TEM in-situ annealing;

   Sammanfattning : Nanocrystalline materials are a relatively new group of materials that are constituted by crystals/grains of a few nanometers in size. Because their mechanical, physical and chemical properties are often superior compared to their microcrystalline counterparts, these materials are attractive for many industrial applications. LÄS MER
