2. 1. Characterizing ions in solution by NMR methods

   Author : Marianne Giesecke; István Furó; Peter Griffiths; KTH; []
   Keywords : electrophoretic NMR; diffusion NMR; NMR imaging; ion pairing; ion association; polyethylene oxide; metal-ion complex; Li ion batteries; electrolyte characterization; Kemi; Chemistry;

   Abstract : NMR experiments performed under the effect of electric fields, either continuous or pulsed, can provide quantitative parameters related to ion association and ion transport in solution.  Electrophoretic NMR (eNMR) is based on a diffusion pulse-sequence with electric fields applied in the form of pulses.

4. 2. Physico-Chemical Properties of Plant Polysaccharides Investigated with NMR Techniques

   Author : Åsa Östlund; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR diffusometry; Dissolution of cellulose; Chemical shift imaging; Fiber hornification; Xylan; Molecular weight; Pore size distribution; Cryoporometry; Cellulose solution; 19F NMR; Gelation of cellulose; Self-diffusion; Pulsed field gradient NMR; TBAF DMSO; 1H NMR;

   Abstract : In the lead of developing new biomaterials from plant sources it is of importance to be able to control and vary the properties, such as flexibility, strength, and hygroscopicity of the final material. These properties are highly directed by the interactions between constituents on a molecular level. READ MORE

5. 3. Drugs and polymers in dissolving solid dispersions : NMR imaging and spectroscopy

   Author : Carina Dahlberg; István Furó; Anna Millqvist-Fureby; Michael Schuleit; Jadwiga Tritt-Goc; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi; PHARMACY; FARMACI;

   Abstract : The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioavailability of the drug.

6. 4. NMR Studies of Gel-Emulsions; Diffusometry and Applications of Novel Field Gradient Techniques

   Author : Carin Malmborg; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; modulated gradients; imaging; Physical chemistry; Fysikalisk kemi; NMR; emulsion; diffusion;

   Abstract : The aim of these studies has been to investigate what information that can be obtained on gel-emulsions with nuclear magnetic resonance, NMR, as the investigating tool. The gel-emulsions are important in many technical applications such as in food products, in cosmetic and pharmaceutical formulations, and in emulsion explosives, just to name a few applications.

7. 5. Technomedical Visions : Magnetic Resonance Imaging in 1980s Sweden

   Author : Isabelle Dussauge; Arne Kaijser; Pär Blomkvist; Eva Åhrén; Anne Beaulieu; KTH; []
   Keywords : HUMANIORA; HUMANITIES; anatomy; body; NMR; psychiatry; radiology; representations; Sweden; visual studies; history of medicine; history of technology; laboratory science; magnetic resonance; mediation; medical gaze; medical imaging; MRI; History of technology; Teknikhistoria;

   Abstract : The medical imaging technology called MRI (magnetic resonance imaging) stems from a blind measurement technology which was further developed in research and practice to enable seeing into the inner body. Vision with MRI was open-ended, and it was developed and tamed in a context of fragmented medical perspectives on the body and on technology. READ MORE
