1. 6. Characterizing ions in solution by NMR methods

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

   Sammanfattning : 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.

3. 7. Responsible provision of online gambling : Effects, usability and gamblers’ experiences of protective measures implemented in online gambling environments

   Författare :Ekaterina Ivanova; Per Carlbring; Philip Lindner; Mark D. Griffiths; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Problem gambling; responsible gambling; responsible provision of gambling; deposit limit; prediction of gambling problems; experiences of responsible gambling tools; attitudes towards responsible gambling tools; online gambling; Psychology; psykologi;

   Sammanfattning : Problem gambling is considered a public health problem in many countries and is associated with serious financial and health-related harms for both problem gamblers and significant others. It is possible to create gambling environments that would promote sustainable gambling behaviors and prevent excessive gambling. LÄS MER

4. 8. Droplet microfluidics for high throughput biological analysis

   Författare :Håkan Jönsson; Helene Andersson-Svahn; Andrew Griffiths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Droplet microfluidics; High throughput biology; Single cell analysis; Hydrodynamic separation; Enzyme amplification; Fluorescence polarization; Microfabrication; Bioengineering; Bioteknik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

   Sammanfattning : Many areas of biological research increasingly perform large-scale analyses.  In genomics the entire gene repertoire of an organism is analyzed.  Proteomics attempts to understand the function and expression patterns of all proteins in a cell or organism. LÄS MER

5. 9. Molecular Association Studied by NMR Spectroscopy

   Författare :Lars Nordstierna; István Furó; Peter Griffiths; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; spin relaxation; self-diffusion; intermolecular cross-relaxation; chemical shift; fluorinated surfactants; hydrogenated surfactant; micelle; non-ideal mixing; adsorption; hydration; surfactant-protein association; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : This Thesis presents studies of molecular association in aqueous solution and at the liquid/solid interface. The investigated molecular systems range from self-aggregating surfactants to hydration water in contact with micelles or individual molecules. In most studies, combinations of various NMR methods were applied. LÄS MER

7. 10. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

   Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER
