  1. 1. Theoretical Studies of Natural Gas Hydrates and H-bonded Clusters and Crystals

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Yuan Liu; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis H-bonded systems (natural gas hydrates, water clusters, and crystal ice) are studied by density functional theory (DFT) computations.Natural gas hydrates (NGHs) play an important role in energy and environmental fields: NGHs are considered as a promising backup energy resource in the near-future due to their tremendous carbon content; improper exploration of NGHs could induce geological disasters and aggravate the greenhouse effect.

  2. 2. Porphyrin Anchored DNA: Advances in DNA Nanotechnology

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jakob Woller; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Fysikalisk kemi; Physical chemistry; Biofysikalisk kemi; Biophysical chemistry;

    Sammanfattning : DNA nanotechnology has focused on the creation of complex structures using DNA as building blocks. DNA is an attractive construction material at the nano scale due to the self-assembly and specific base-pairing of the DNA bases, allowing the placement of functional groups with sub-nm precision.
