    Abstract : The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. READ MORE

  5. 3. Cleavable Cationic Gemini Surfactants

    Author : Ali Tehrani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical hydrolysis; esterquat; gemini; biodegradation; adsorption; cleavable; synthesis; betaine ester; surfactant; solubilization; shape and size of micelle;

    Abstract : This research project concerns investigations of ester-containing cationic gemini surfactants (esterquat and betaine ester types). These dimeric surfactants are compared with their monomeric counterparts. READ MORE

  6. 4. Lipases at interfaces

    Author : Pedro Reis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrolysis.; fat; microenvironment; depletion; surfactant; interface; Lipase; modulation; digestion; synthesis;

    Abstract : Lipases are acyl hydrolases that play a key role in fat digestion by cleaving long-chain triglycerides into polar lipids. Due to an opposite polarity between the enzyme (is hydrophilic) and their substrates (are lipophilic), the lipase reaction occurs at the interface between the aqueous and the oil phases. READ MORE

  7. 5. Synthesis of Polyhydroxylated Surfactants : Comparison of Surfactant Stereoisomers and Investigation of Haemolytic Activity

    Author : Kristina Neimert-Andersson; Peter Somfai; Krister Holmberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyhydroxy surfactants; Sugar surfactants; Dihydroxylation; Metathesis; Langmuir monolayers; Chiral discrimination; Haemolysis; Organic chemistry; Organisk kemi;

    Abstract : I den här avhandlingen har vi studerat hur man kan göra nya tensider. En tensid är en speciell molekyl som har förmågan att lösa sig i både vatten och olja. Man kan göra följande experiment hemma: Fyll en glasburk till hälften med vatten och tillsätt en droppe matolja. READ MORE
