2. 1. NMR Self-Diffusion Studies and Stability Studies of Emulsions

   Author : Ingrid Lönnqvist; LTH Ingenjörshögskolan vid Campus Helsingborg; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; coalescence; emulsion stability; size distribution; restricted diffusion; self-diffusion coefficient; self-diffusion PGSE NMR; surfactant; emulsifier; continuous phase; microemulsion; phase diagram; emulsion; multiple emulsion; cream; conductivity; Physics; Fysik; Chemistry; Kemi;

   Abstract : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. READ MORE

4. 2. Multifunctional Carbon Foams by Emulsion Templating : Synthesis, Microstructure, and 3D Li-ion Microbatteries

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Battery; Carbon; Electrochemical; Electrodeposition; Emulsion; Energy; Exfoliation; Foam; Lithium; Microbattery; Multifunctional; Nanoparticles; Polyaniline; Polymer; Power; Sol-gel; Storage; Structured; Three-dimensional; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. READ MORE

5. 3. Water-in-diesel emulsion and microemulsion fuels: composition, structure and effect on emissions

   Author : Anna Lif; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx; microemulsion; combustion; diffusometry; alternative fuels; emission; emulsion; Fischer-Tropsch; MFC; PM; microfibrillated cellulose; NMR; surfactant; soot; diesel;

   Abstract : Water-in-diesel fuels, as emulsions and microemulsions, give reduced emissions of nitrogen oxides (NOx) and particulate matter (PM) in combustion in diesel engines compared to regular diesel. These fuels can contribute to an improved local environment in densely populated areas as they can replace regular diesel in existing vehicles without any engine modification requirements. READ MORE

6. 4. Emulsion formation and stability - Impact of the dispersed state of the emulsifier on emulsification

   Author : Emma Magnusson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emulsion; phospholipid; dispersed state; field flow fractionation; freeze-thaw stability;

   Abstract : Emulsions find a variety of applications in for example food, cosmetics and pharmaceutical preparations. In order to obtain emulsions with desired properties it is important to understand how different factors, such as the properties of the emulsifier and the emulsification procedure, impact the final emulsion properties.

7. 5. Water-in-diesel emulsion and microemulsion fuels -The effect of water on emission levels

   Author : Anna Lif; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Combustion; Diesel; Soot; NMR; Microemulsion; PM; Emulsion; Surfactant; NOx; Diffusometry; Alternative fuels; Emission;

   Abstract : Water-in-diesel emulsions are known as environmentally favourable alternatives to conventional diesel fuel. Introducing water into the combustion results in reduced emissions of the health hazardous components nitrogen oxide (NOx) and particulate matter (PM). The concept of using emulsions is advantageous as it is easy to replace regular diesel. READ MORE
