1. 11. Properties of Multifunctional Oxide Thin Films Despostied by Ink-jet Printing

   Författare :Mei Fang; Lyubov Belova; K. Venkat Rao; Gillian Gehring; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ink-jet printing; oixde; thin film; ink; suspension; dye sensitized solar cell; functional properties; magnetism; diluted magnetic semiconductors;

   Sammanfattning : Ink-jet printing offers an ideal answer to the emerging trends and demands of depositing at ambient temperatures picoliter droplets of oxide solutions into functional thin films and device components with a high degree of pixel precision. It is a direct single-step mask-free patterning technique that enables multi-layer and 3D patterning. LÄS MER

3. 12. Estimating win-win potential between supplier and customer : a model applied within civil jet engine maintenance

   Författare :Lars Wikberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

   Sammanfattning : Organisations around the world are today looking for new approaches to maintain or develop competitive advantages, reduce costs, free-up capital and improve quality and service. The traditional customer-supplier relation is characterised by the parties focusing on their own cost reduction, creating win-loose scenarios. LÄS MER

4. 13. Air jets in ventilation applications

   Författare :Yue Zou; KTH; []
   Nyckelord :Air jet; velocity; ventilation; CFD; measurement;

   Sammanfattning : The purpose of air distribution systems for HVAC is tocreate proper air quality and thermal conditions in an occupiedzone. In mixing type air distribution systems air is suppliedinto a room through various types of outlets and distributed byturbulent air jets. These air jets are the primary factorsaffecting room air motion. LÄS MER

5. 14. A Study of Mach 0.75 Jets and Their Radiated Sound Using Large-Eddy Simulation

   Författare :Niklas Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Jet noise; CAA; LES; Large Eddy Simulation; Computational Aero-Acoustics;

   Sammanfattning : Large-Eddy Simulations (LES) of a compressible nozzle/jet configuration have been carried out. Two jets were simulated, an isothermal jet and a jet with a higher temperature than the surrounding air. The Mach number was in both cases 0.75 and the jet Reynolds number was 50,000. LÄS MER

7. 15. A new laser-plasma X-ray source for microscopy and lithography

   Författare :Lars Rymell; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray lithography; Atomic and molecular physics; multilayer mirror; Fysicumarkivet A:1997:Rymell; Atom- och molekylärfysik; X-ray source; Laser-produced plasma; liquid droplet; debris-free; water window;

   Sammanfattning : A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. LÄS MER
