   Författare :Geng Wang; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; calorimetry; differntial scanning; isothermal titration; enthalpy; electrolyte; micelles; self-association; thermal gelling; interaction; alkyltrimethylammonium halides; sodium dodecylsulfate; surfactants; polymers; ethyl hydroxylethyl cellulose; viscosity; phase behavior; self-diffusion NMR; Physics; Fysik; Chemistry; Kemi; Fysicumarkivet A:1997:Wang;

   Sammanfattning : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. LÄS MER

3. 2. Equilibrium and Kinetic Studies of the Binding of DNA to Cationic Liposomes

   Författare :Paula Barreleiro; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small-Angle Neutron Scattering; Fluorescence; Kinetics; Stopped-Flow; Differential Scanning Calorimetry; Titration Calorimetry; Gel-to-Liquid Crystalline Phase Transition; Lamellar phase; Lipolexes; DNA; Liposomes; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : The objective of this work was to study the formation of DNA-cationic vesicle complexes (lipoplexes). These complexes are interesting not only from a fundamental point of view but also as promising candidates for gene therapy. The approach taken was to study first the cationic vesicles by themselves.

4. 3. Amylopectin - Interactions with Lipids and Proteins

   Författare :Henrik Lundqvist; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binding isotherm; isothermal titration calorimetry; differential scanning calorimetry; retrogradation; alpha-lactalbumin; beta-lactoglobulin; whey protein; surfactant; lipid; exterior chain length; barley; potato; starch; amylopectin; amylose; Food and drink technology; Livsmedelsteknik; Proteins; enzymology; Proteiner; enzymologi; Lipids; steroids; membranes; Lipider; steroider; mebran;

   Sammanfattning : Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins.

5. 4. Physics of Viral Infectivity: Energetics of Genome Ejection

   Författare :Meerim Jeembaeva; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microfluidics.; differential scanning calorimetry; capsid; Key words: phage; osmotic suppression; DNA ejection; isothermal titration calorimetry; enthalpy;

   Sammanfattning : All viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. LÄS MER

7. 5. Imperfections in Recycled Aluminium-Silicon Cast Alloys

   Författare :Anton Bjurenstedt; Anders Jarfors; Salem Seifeddine; Pål Schmidt; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Imperfections; Recycled cast Al-Si alloy; Fe-rich particles; Melt quality; Fractography; Differential scanning calorimetry.;

   Sammanfattning : In striving to produce high quality cast components from recycled aluminium alloys,imperfections have to be considered, because recycled aluminium usually containsmore of it. However, there are great energy savings to be made by using recycledaluminium; as little as 5% of the energy needed for primary aluminium productionmay be required. LÄS MER
