2. 1. Polymer extraction and utilization of brown algal biomass

   Author : Martin Sterner; Ulrica Edlund; Fredrik Gröndahl; Marguerite Rinaudo; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Algae; Saccharina latissima; alginate; brown seaweed; extraction; filament; chelation; gel; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. READ MORE

4. 2. Coal and Oil: The Dark Monarchs of Global Energy : Understanding Supply and Extraction Patterns and their Importance for Future Production

   Author : Mikael Höök; Kjell Aleklett; David Rutledge; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oil production; coal production; depletion rate; forecasting; energy supply; Physics; Fysik; Other earth sciences; Övrig geovetenskap; Physical planning; Fysisk planläggning; Other engineering physics; Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

   Abstract : The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind.  This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil.

5. 3. Extraction and chromatography of bioactive compounds in complex samples using supercritical CO2 technology

   Author : Said Alhamimi; Centrum för analys och syntes; []
   Keywords : Supercritical CO2; Chromatography; Extraction; Mass transfer; Solubility;

   Abstract : Bioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. READ MORE

6. 4. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures

   Author : José da Cruz Francisco; Kemiska institutionen; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural oils; fats and waxes technology; Naturliga oljor; fetter; vax; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; phase behavior; soybean lecithin; monoolein; cineole; terpenes; eucalyptus; extraction; Essential oils; supercritical carbon dioxide;

   Abstract : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. READ MORE

7. 5. Exploring the functionality of coconut proteins

   Author : Borges Chambale; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coconut; coconut milk; extraction; proteins; emulsions; functional properties; denaturation; gels; yield stress; glass structure;

   Abstract : At present, coconut proteins are discarded as a waste product by the coconut oil industry. If the range of applications of coconut proteins is to be expanded, their potential functionalities should be investigated. Emulsions and gels are of the greatest interest in food industry. READ MORE
