1. 21. Capillary electrophoresis mass spectrometry applied to structural proteomics and small molecule analysis

   Författare :Jordan Aerts; Erik T. Jansson; Per E. Andrén; Petr Man; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Capillary Electrophoresis Mass Spectrometry; Hydrogen Deuterium Exchange Mass Spectrometry; Enantioselective Separations; Drugs of Abuse; Analytical Chemistry; Analytisk kemi; Analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

   Sammanfattning : Capillary electrophoresis with mass spectrometric (CE–MS) detection offers a separation method without equal in terms of flexibility, utility, and cost efficiency. Here we demonstrate precisely this through the application of several laboratory-built CE–MS instruments for the separation of brain metabolites in non-primates, enantioselective separations of synthetic anesthetic metabolites in fractionated pony urine, application in structural proteomics workflows, and identification of exogenous alkaloid biotransformationproducts in human cerebrospinal fluid (CSF).

3. 22. Engineered ion-bombardment as a tool in thin film deposition

   Författare :Rommel Paulo B. Viloan; Ulf Helmersson; Daniel Lundin; Rainer Hippler; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HiPIMS; Bipolar HiPIMS; Ion-bombardment; Thin film;

   Sammanfattning : Energetic-ion bombardment has become an attractive route to modify the crystal growth and deposit high quality thin films. In high-power impulse magnetron sputtering (HiPIMS) where the discharge is characterized by a significant amount of ions of the sputter-ejected atoms, energetic-ion bombardment effects could not be underestimated.

4. 23. Melt spinning of poly(vinylidene fluoride) mono- and bicomponent fibres and yarns : the formation of piezoelectric beta-phase crystallinity

   Författare :Anja Lund; Högskolan i Borås; []
   Nyckelord :fibres; PVDF; Textilteknologi;

   Sammanfattning : The present study investigates the possibilities of manufacturing piezoelectric polymer fibres or yarns for integration into textile materials. The polymers known to give the strongest piezoelectric effects are poly(vinylidene fluoride) (PVDF) and some of its copolymers. LÄS MER

5. 24. Development of on-line diagnostic methods for medium voltage XLPE power cables

   Författare :Valentinas Dubickas; Hans Edin; Roland Eriksson; Matti Lehtonen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

   Sammanfattning : On-line diagnostics of power system components is an important area since it allows the diagnostics to be performed at regular intervals during the normal operation of the components. This combined with reliability centered maintenance could lead to reduced customer outages. LÄS MER

7. 25. Spatial metabolomics using Surface Sampling Capillary Electrophoresis Mass Spectrometry  : New tool for direct surface sampling chemical analysis of biological samples

   Författare :Anastasia Golubova; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Analytical surface sampling tools enable direct chemical studies of solid biological samples, including morphologically diverse tissue, and provide both fast chemical analysis with minimum sample preparation and information about molecular spatial distribution. Spatially resolved investigations of tissue sections could help to reveal pathological mechanisms at specific tissue locations. LÄS MER
