1. 16. Characterization of Membrane Proteins: From a gated plant aquaporin to animal ion channel receptors

   Författare :Sabeen Survery; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MIPs; AQPs; TRP ion channels; water transport; themo sensor; Electrophiles;

   Sammanfattning : Membrane proteins play several important roles in a cell. Among these proteins are aquaporins (AQPs) and transient receptor potential (TRP) ion channels that mediate water transport, temperature and noxious chemical sensation, respectively. LÄS MER

3. 17. Catalytic reactions and hydrogen sensing with Pt- and Pd-MIS devices

   Författare :Anette Salomonsson; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The hydrogen sensitivity of catalytic metal-insulator-semiconductor (MIS) devices has been known for almost 30 years [1,2]. With Pd or Pt as the metal gate the electronic properties of the device are influenced by hydrogen and the device can thereby be used as a gas sensor for hydrogen and hydrogen containing gases.

4. 18. SiC based field effect sensors and sensor systems for combustion control applications

   Författare :Mike Andersson; Anita Lloyd Spetz; Udo Weimar; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SiC; Field Effect Sensors; Combustion Control; Other physics; Övrig fysik;

   Sammanfattning : Increasing oil prices and concerns about global warming have reinforced the interest in biofuels for domestic and district heating, most commonly through combustion of solid biomass like wood logs, hog fuel and pellets. Combustion at non-optimal conditions can, however, lead to substantial emissions of noxious compounds like unburned hydrocarbons, carbon monoxide, and nitrogen oxides as well as the generation of soot.

5. 19. Computer assisted evaluation of gas sensors : theory and applications

   Författare :Dennis Söderberg; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The application of a low cost computer as program control in a laboratory experimental situation is valuable for the evaluation of a complex measurement problem. The first step in a computer assisted evaluation is to design the experimental methods and construct the apparatus. LÄS MER

7. 20. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring

   Författare :Peter Tobias; Ignaz Eisele; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide; high temperature; gas sensors; field effect devices; MISdevices; Schottky diodes; experimental design; reaction kinetics; mass transport; car exhaust; multipoint injection; response times; cylinder specific; on-board diagnosis;

   Sammanfattning : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.
