  4. 2. Pre-biotic molecules and dynamics in the ionosphere of Titan : a space weather station perspective

    Author : Oleg Shebanits; Jan-Erik Docent; Ingo Müller-Wodarg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Saturn; Titan; Ionosphere; Langmuir Probe; Space and Plasma Physics; Rymd- och plasmafysik;

    Abstract : Saturn’s largest moon Titan (2575 km radius) is the second largest in the Solar system. Titan is the only known moon with a fully developed nitrogen-rich atmosphere with ionosphere extending to ~2000 km altitude, hosting complex organic chemistry. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Titan’s ionosphere and dust : – as seen by a space weather station

    Author : Oleg Shebanits; Jan-Erik Wahlund; Wolf Dietrich Geppert; Olle Björneholm; Erik Vigren; Cesar Bertucci; Uppsala universitet; []

    Abstract : Titan, the largest moon of Saturn, is the only known moon with a fully developed nitrogen-rich atmosphere, its ionosphere is detectable as high as 2200 km above its surface and hosts complex organic chemistry. Titan’s atmosphere and ionosphere has striking similarities to current theories of these regions around Earth 3.5 billion years ago. READ MORE

  7. 5. Concepts for hot sheet metal forming of titanium alloys

    Abstract : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. READ MORE
