1. 6. Synchrotron radiation induced fluorescence spectroscopy of gas phase molecules

   Författare :Jesús Álvarez Ruiz; Elisabeth Rachlew; J. E. Rubensson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; molecular spectroscopy; photon induced fluorescence; synchrotron radiation; superexcited states; Fysik; Physics; Fysik;

   Sammanfattning : A new experimental set-up for gas phase fluorescence studies using synchrotron radiation has been designed and constructed to perform simultaneously total and dispersed fluorescence measurements. Neutral photodissociation of CO has been investigated after excitation with 19-26 eV photons. LÄS MER

3. 7. Towards Self-Powered Devices Via Pressure Fluctuation Energy Harvesters

   Författare :Jesus Javier Lechuga Aranda; Bengt Oelmann; Sebastian Bader; Meiling Zhu; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The growing interest in the Internet of Things has created a need for wireless sensing systems for industrial and consumer applications. In hydraulic systems, a widely used method of power transmission in industry, wireless condition monitoring can lead to reduced maintenance costs and increase the capacity for sensor deployment.

4. 8. Interfaces In Hydraulic Pressure Energy Harvesters

   Författare :Jesus Javier Lechuga Aranda; Bengt Oelmann; Sebastian Bader; Olfa Kanoun; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The fourth industrial revolution is here and with it a tidal wave of challenges for its prosperous implementation. One of the greatest challenges frustrating the development of the internet of things, and hence the next industrial revolution, is the powering of wireless sensors, as these depend on batteries with a limited lifetime.

5. 9. Aging effects on commercial lean NOx trap catalysts

   Författare :Jesus De Abreu Goes; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aging; thermal degradation; sulfur poisoning; characterization; commercial lean NOx traps; NOx storage and reduction;

   Sammanfattning : As a countermeasure to global warming, vehicles with low carbon emissions are being investigated by promoting lean-burn engines and high combustion efficiencies. However, one limitation to the increasing use of these engines is the need to develop corresponding catalytic systems for controlling the nitrogen oxide (NOx) emissions in their lean exhaust.

7. 10. Deactivation mechanisms influencing the performance and durability of exhaust aftertreatment systems

   Författare :Jesus De Abreu Goes; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal degradation; Gasoline particulate filters; Lean NOx traps; Sulfur poisoning.;

   Sammanfattning : As countermeasure to air pollution and global warming, more stringent environmental policy measures will probably come into force with the future emission standards, which will require important developments for gasoline and diesel vehicles to meet the emerging criteria. Efficient catalytic formulations and advanced strategies for exhaust aftertreatment systems will be therefore demanded to provide both high catalytic activity and stability, minimizing the environmental impact by automobiles.
