1. 1. NMR studies of complex fluids and solids formed by surfactants

   Författare :Niklas Hedin; KTH; []
   Nyckelord :CTAB; CTAC; decane; benzene; polysaccharide; micelle; microemulsion; self diffusion;

   Sammanfattning : NMR methods have been designed and employed in studying ofcomplex liquids and solids formed by surfactants. PGSE NMRexperiments are easily biased by convection; this artifact canbe avoided by changing the sample holder and by usingconvection-compensated pulse sequences. LÄS MER

   Sammanfattning : The thesis concerns polyelectrolyte gels in contact with oppositely charged proteins and surfactant micelles, and includes of four papers (I-IV). In paper I confocal Raman spectroscopy was introduced as a method to trace micelles and investigate the structure of gel-surfactant complexes, in phase separated gel spheres. LÄS MER

4. 3. Synthesis and characterization of Pd nanoparticles for plastic plasmonic sensing applications

   Författare :Alicja Stolas; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasmon resonance; hydrogen sensing; polymers; nanoparticles;

   Sammanfattning : It is well known that hydrogen mixed with air forms a highly flammable mixture. There is an urgent need for selective and accurate sensors, since hydrogen very often serves as a fuel or energy storage medium. Given the fact that even the smallest leak can lead to an explosion, it is very important for sensors to be reliable and safe, i.e. LÄS MER

5. 4. Genes for cytochrome c and cytochrome c oxidase synthesis in Bacillus subtilis

   Författare :Jenny Bengtsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; cytochrome; cytochrome c oxidase; Bacillus subtilis; cytochrome c synthesis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Cytochromes are heme-containing proteins that function in electron transfer reactions, e.g. respiration and photosynthesis. There are several different types of cytochromes. LÄS MER

7. 5. Shape Control Synthesis and Microstructure Studies of Metal Nanoparticles

   Författare :Xin Wen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hexadecyltrimethylammonium bromide; sodium oleate; polyvinylpyrrolidone; Gold nanorod; palladium nanodendrite; seed mediated growth; transmission electron microscopy; hexadecyltrimethylammonium chloride;

   Sammanfattning : Metal nanoparticles have been extensively studied in recent years due to their unique chemical, biological and physical properties. Gold (Au) and palladium (Pd) nanoparticles are two of the most popular materials because Au nanoparticles have a strong localized surface plasmon resonance effect and Pd nanoparticles have high hydrogen adsorption and chemical catalytic capacities.
