  1. 1. A Microcalorimetric Study of Macrocyclic Complexes in Aqueous Solution

    University dissertation from Thermochemistry Division, Chemical Center, Lund University

    Author : Magnus Stödeman; Lund University.; Lunds universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Aqueous Solution; Calixarene; Cyclodextrin; Vaporization; Macrocyclic compounds; Microcalorimetry; Kemi;

    Abstract : The present work involves a microcalorimetric characterization of the interactions among macrocyclic compounds and aliphatic molecules in aqueous solution. The macrocyclic compounds used in the study are a-,b- and g-cyclodextrin and 25,26,27,28-tetrahydroxycalix[4]arene-5,11,17,23- tetrasulphonate. READ MORE

  2. 2. Synergistic interactions involving amphiphilic polymers in solution

    University dissertation from Physical Chemistry 1, Lund University

    Author : Maria Karlberg; Lund University.; Lunds universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic modification; cyclodextrin; rheology; emulsion stability; Fysikalisk kemi; Physical chemistry; cellulose derivative; degradable surfactants; amylose;

    Abstract : The properties of hydrophobically modified cellulose derivatives in aqueous mixtures with various other molecules have been investigated. Mixtures of a hydrophobically modified polymer and alkali-sensitive, degradable surfactants gave rise to time-dependent viscosities. READ MORE

  3. 3. Hydrophobically Modified Polymers. Rheology and Molecular Associations

    University dissertation from Physical Chemistry 1, Lund University

    Author : Leif Karlson; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer self diffusion; Physical chemistry; Fysikalisk kemi; rheology; hydrophobically modified polyethylene glycol; hydrophobically modified ethyl hydroxyethyl cellulose; cyclodextrin; hydrophobically modified polymer; associative thickener;

    Abstract : Structure- property relationships and thickening mechanism in aqueous solution of two hydrophobically modified polymers (HM-P) with different architecture have been investigated. The two polymers, hydrophobically modified ethyl hydroxyethyl cellulose (HM-EHEC) and hydrophobically modified polyethylene glycol (HM-PEG), are commonly used as associative thickeners in the paint industry.

  4. 4. Molecular Dynamics Simulations of Biomimetic Carbohydrate Materials

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Qiong Zhang; KTH.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics simulation; carbohydrate; cellulose; xyloglucan; cyclodextrin; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

    Abstract : The present thesis honors contemporary molecular dynamics simulation methodologies which provide powerful means to predict data, interpret observations and widen our understanding of the dynamics, structures and interactions of carbohydrate systems. With this as starting point my thesis work embarked on several cutting edge problems summarized as follows. READ MORE

  5. 5. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Vladimir Kirejev; Göteborgs universitet.; Gothenburg University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

    Abstract : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. READ MORE
