  1. 1. Alkylglucosides - physical chemical properties

    Författare :Frederik Nilsson; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. LÄS MER

    Sammanfattning : The search for alternate and renewable energy resources as well as the efficient use of energy and development of such systems that can help to save the energy consumption is needed because of exponential growth in world population, limited conventional fossil fuel resources, and to meet the increasing demand of clean and environment friendly substitutes. Hydrogen being the simplest, most abundant and clean energy carrier has the potential to fulfill some of these requirements provided the development of efficient, safe and durable systems for its production, storage and usage.
