    Author : Helen Sjögren; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; tyrosine ; co-poly-L lysine; phenylalanine ; co-poly-L- lysine; poly-L-glutamate; poly-L-lysine; poly-L-valine; poly-L-isoleucine; poly-gamma-methyl-L-glutamate; poly-L-leucine; monolayer; Langmuir-Blodgett film; CD spectroscopy; random coil; alpha-helix; surfactant stabilisation; polypeptide; polyamino acid;

    Abstract : The aim of this thesis work is to understand and be able to control polypeptide conformation and interactions at interfaces and in solution by changing the solution conditions. For this purpose simple model polypeptides, so-called polyamino acids, have been investigated at the air-liquid interface, as well as in aqueous solutions. READ MORE

  2. 2. Functional hybrid and composite porous membranes derived from imidazolium-type poly(ionic liquid)

    Author : Atefeh Khorsand Kheirabad; Jiayin Yuan; Naser Tavajohi Hassan Kiadeh; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly ionic liquid ; porous polyelectrolyte membranes; composite materials; functional membranes; materialkemi; Materials Chemistry;

    Abstract : Poly(ionic liquid)s (PIL)s, as a subclass of polyelectrolytes, are composed of polymeric backbones with ionic liquid (IL)-based species in each repeating unit. Recent studies have deepened the understanding of the PIL concept in terms of characteristics, functions and applications in comparison to classical ILs and traditional polyelectrolytes. READ MORE

  3. 3. Heteroatom-doped porous carbon materials derived from poly(ionic liquid)s and their composites for battery and catalytic applications
