  1. 1. Material development of a textile bioreactor : All-polyamide composite for the construction of bioreactors

    Författare :Mostafa Jabbari; Mikael Hedenqvist; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; textile bioreactor; biofuel; coated fabric; all-polyamide composite; polyvinyl chloride PVC ; solvent replacement; Hansen solubility parameters HSPs ; Resource Recovery; Resursåtervinning;

    Sammanfattning : Bioreactors are manufactured from stainless/carbon steel, concrete, glass, etc., which are costly and time-consuming to install. Recently, several research studies have been initiated to find cost-efficient materials for constructing bioreactors, one of which is coated textiles. LÄS MER

  3. 2. The Synthesis and Use of Certain Pyridine Derivatives as Modulators of the G-protein Coupled Receptors mGlu5 and P2Y12

    Författare :Peter Bach; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mGluR5; P2Y12; gastroesophageal reflux disease GERD ; thrombosis; ethyl nicotinates; ureas; sulfonylureas; oxazoles; bioisosteres; regioselectivity; solvent effect.;

    Sammanfattning : The glutamatergic mGlu5 receptor and the purinergic P2Y12 receptor are two important targets in the development of novel treatments of gastroesophageal reflux disease (GERD) and thrombosis, respectively. Synthesis was developed to investigate the structure-activity relationships (SAR) of a novel series of 2-alkynylpyridine derivatives as mGluR5 antagonists. LÄS MER

  4. 3. Molecular structure, interactions, and dynamics of novel Li-battery electrolytes

    Författare :Luis Aguilera Medina; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAXS; Raman scattering; imidazolium; NSE; lithium ion battery; electrolyte; organic solvent; pyrrolidinium; TFSI; ionic liquid;

    Sammanfattning : Lithium-ion batteries are one of the most promising candidates for energy storage in sustainable technologies such as electro-mobility or renewable energy systems. However, at present they are incapable to compete with the combustion engine to power vehicles in terms of capacity, price, and safety. LÄS MER

  5. 4. Exploring Conjugate Addition Activity in Pseudozyma antarctica Lipase B

    Författare :Maria Svedendahl; Per Berglund; Olof Ramström; Amelie Eriksson Karlström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica lipase B · conjugate addition · enzyme catalysis · enzyme catalytic promiscuity · molecular modeling; Biochemistry; Biokemi;

    Sammanfattning : Multifunctional enzymes have alternative functions or activities, known as “moonlighting” or “promiscuous”, which are often hidden behind a native enzyme activity and therefore only visible under special environmental conditions. In this thesis, the active-site of Pseudozyma (formerly Candida) antarctica lipase B was explored for a promiscuous conjugate addition activity. LÄS MER

  7. 5. Analytical Supercritical Fluid Extraction of Lipid Containing Samples

    Författare :Mattias Järemo; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SFC; extraction cell; liquid samples; fat retainers; lipids; SFE; carbon dioxide; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Traditionally, sample work-up has been associated with different kinds of liquid extraction techniques involving a large consumption of hazardous solvents. There are today regulations that aims at replacement of dangerous chemicals which has created a need for new extraction techniques. LÄS MER
