  1. 21. Can planet formation explain the observed differences in the chemical composition of binary stars?

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Rebecca Forsberg; [2017]
    Keywords : binary stars; planet formation; protoplanetary disc; Physics and Astronomy;

    Abstract : A suggested explanation for the observed differences in chemical abundances in binary stars has been planet formation (e.g. Tucci Maia et al. 2014). READ MORE

  3. 22. Chemical composition of giant planet hosts

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Frida Ekstrand; [2017]
    Keywords : chemical composition; planet hosts; stellar twins; differential abundance analysis; Physics and Astronomy;

    Abstract : Does the formation of planets give imprints on the chemical composition of the host star? In order to test this theory a differential abundance analysis (i.e. comparing two stars' abundances to each other) was carried out on a few stars with and without known planets, to see if any differences were found.

  4. 23. Measuring volatile nicotine from electronic cigarettes

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Simon Lundegard; [2017]
    Keywords : AMS; denuder; e-juice; electronic cigarettes; NGI; nicotine; SMPS; Technology and Engineering; Chemistry;

    Abstract : This thesis is focused on electronic cigarettes and the formulations (also known as e-juices) associated with these. The reason is that there have been countless studies on the health effects and nicotine delivery of normal cigarettes, but not as much on electronic cigarettes. READ MORE

  5. 24. Structural Investigations of HiPIMS-deposited Diamond-Like Carbon Thin Films using Raman Spectroscopy

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Andreas Eriksen Tell; [2017]
    Keywords : ;

    Abstract : Diamond-like carbon (DLC) is a versatile material which exhibits excellentmechanical, electrical and optical properties making it suitable for applications rangingfrom biomedical implants to engine components. The properties of DLC thin films aredetermined by the bonding configuration (sp3/sp2 fraction) of its carbon atoms. READ MORE

  6. 25. Understanding Sn-seeded InSb nanowire growth

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Hengfang Zhang; [2017]
    Keywords : Science General;

    Abstract : III-Sb semiconductor nanowires have drawn a lot of attention because of their many promising applications, such as thermoelectric generation, low power high efficient electronics and quantum transport. Gold as a catalyst seed particle has been dominating for many years assisting nanowires growth. READ MORE
