  1. 6. Structure and spectroscopy of bio- and nano-materials from first-principles simulations

    Författare :Weijie Hua; Yi LUO; Mauro Stener; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soft x-ray spectroscopy; bio- and nano-materials; first-principles simulation; host-guest interaction; generalized energy-based fragmentation; Quantum chemistry; Kvantkemi; Spectroscopy; Spektroskopi; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : This thesis is devoted to first-principles simulations of bio- and nano-materials,focusing on various soft x-ray spectra, ground-state energies and structures of isolated largemolecules, bulk materials, and small molecules in ambient solutions. K-edge near-edge x-ray absorption fine structure (NEXAFS) spectra, x-ray emission spectra, andresonant inelastic x-ray scattering spectra of DNA duplexes have been studied by means oftheoretical calculations at the density functional theory level.

  3. 7. Computational studies of DNA sequencing with graphene nanopores

    Författare :Lijun Liang; Yaoquan Tu; Alexander Lyubartsev; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA sequencing; Graphene nanopore; Molecular dynamic simulation; Kemi; Chemistry;

    Sammanfattning :     The aim of DNA sequencing is to obtain the order of DNA composition comprising the base pairs A (adenine) T (thymine), and C (cytosine) G (guanine). The fast development of DNA sequencing technology allows us to better understand the relationships among diseases, inheritance, and individuality. LÄS MER

  4. 8. The transistor, with emphasis on its use for radio frequency telecommunication

    Författare :Ted Johansson; Dag Sigurd; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is about transistors, integrated circuits and techniques to fabricate electronic devices in semiconductor materials. The most important application area for the transistors studied in the thesis is radio frequency telecommunication. LÄS MER
