1. 11. Stabilitly analysis of large structures founded on rock : an introductory study

   Författare :Fredrik Johansson; Håkan Stille; Anders Fredriksson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; Byggnadsteknik;

   Sammanfattning : Previous investigations of Swedish and international dams have shown difficultiesto assess the safety against failure in rock foundations. The problem was alsogiven additional interest in connection to the recent construction of the newbridge at Traneberg in Stockholm. LÄS MER

3. 12. Electroosmotic pumps with electrochemically active electrodes

   Författare :Per Erlandsson; Nathaniel D Robinson; Mats Fahlman; Adrienne Minerick; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Electrokinetic phenomena, motion caused by an applied electric field, can be used to separate molecules based on charge as in capillary electrophoresis, or pump liquids with electroosmosis. As microfluidic devices are becoming more advanced, involving multiple stages (sequential reactions) and requiring smaller amounts of reagent, the demand for precise fluid control and integrated electrodes increases.

4. 13. Monolithic separation media synthesized in capillaries and their applications for molecularly imprinted networks

   Författare :Julien Courtois; Knut Irgum; Ruth Freitag; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bupivacaine; etching; phosphorylated tyrosine; poly ethylene glycol ; silanization; transmission electron microscopy; fused silica capillaries; isothermal titration calorimetry; local anæsthetic; molecularly imprinted polymer; monolith; nuclear magnetic resonance; Analytical chemistry; Analytisk kemi;

   Sammanfattning : The thesis describes the synthesis of chromatographic media using several different approaches, their characterizations and applications in liquid chromatography. The steps to achieve a separation column for a specific analyte are presented. The main focus of the study was the design of novel molecularly imprinted polymers. LÄS MER

5. 14. Molecularly Imprinted Matrices for Electrochromatography

   Författare :Leif Schweitz; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical technology and engineering; capillary electrophoresis; enantiomer; film coating; microparticle; continuous bed; monolith; molecular imprinting; capillary electrochromatography; Kemiteknik och kemisk teknologi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : This thesis deals with the combination of electrochromatography and molecular imprinting technology. Electrochromatography is characterised by high separation efficiency, simple instrumentation, and minute consumption of sample. LÄS MER

7. 15. Mathematical Modelling in Catalytic Automotive Pollution Control

   Författare :Lennart Andersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automotive pollution control; matematical modelling; monolith; selective catalytic reduction; mass transfer;

   Sammanfattning : Design and control of honeycomb monolith reactors for catalytic automotive pollution control by mathematical modelling of the reactor has been studied. One aspect of the design has been that the use of metallic monolithic catalysts for automotive emission control raises certain optimization possibilities. LÄS MER
