  1. 1. Nitriles in Prebiotic Chemistry and Astrobiology

    Författare :Hilda Sandström; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; astrobiology; polymer chemistry; hydrogen cyanide; density functional theory; molecular dynamics; metadynamics; umbrella sampling; prebiotic chemistry;

    Sammanfattning : Life appeared on Earth within a billion years of the planet’s formation. How? - no one knows. Theories regarding the origin of life involve reactions of molecules predicted to have existed on early Earth in what is called prebiotic chemistry. LÄS MER

  3. 2. Conversion of xylan into value-added products

    Författare :Reza Faryar; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xylooligosaccharides; biosurfactant; prebiotic; xylan-based film; Lactobacillus brevis;

    Sammanfattning : Today’s high demand on finding sustainable energy sources, replacing petroleum-based products and the needfor healthier food alternatives have forced us to search for natural recoverable resources and explore their manyhidden applications. One such resource is xylan, which has gained much attention as possible raw material forvarious exploitations. LÄS MER

  4. 3. Aloe barbadensis Mill. as a therapeutic option for irritable bowel syndrome

    Författare :Bani Ahluwalia; Göteborgs universitet; []

    Sammanfattning : Irritable bowel syndrome (IBS) is a chronic and prevalent functional gastrointestinal disorder, with an incompletely understood pathophysiology. Because of the disease complexity and heterogeneity, the currently available treatment options for IBS are limited. LÄS MER

  5. 4. Quantum Chemical Exploration of Nitriles in Prebiotic Chemistry and Astrobiology

    Författare :Hilda Sandström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metadynamics; astrochemistry; iminoacetonitrile; hydrogen cyanide; acrylonitrile; azotosome; Titan;

    Sammanfattning : The Universe hosts countless different chemical environments, such as planets, moons, comets and the interstellar medium. The diverse pressures, temperatures and chemical compositions of these environments make a wide variety of processes possible. LÄS MER

  7. 5. Modelling Evolution : From non-life, to life, to a variety of life
