2. 1. Surface coatings as xenon diffusion barriers on plastic scintillators : Improving Nuclear-Test-Ban Treaty verification

   Author : Lisa Bläckberg; Mattias Klintenberg; Henrik Sjöstrand; Anders Ringbom; Stephan Pomp; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plastic scintillator; Radioxenon; Diffusion barrier; Surface coating; Atomic Layer Deposition; Comprehensive Nuclear-Test-Ban Treaty; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : This thesis investigates the ability of transparent surface coatings to reduce xenon diffusion into plastic scintillators. The motivation for the work is improved radioxenon monitoring equipment, used with in the framework of the verification regime of the Comprehensive Nuclear-Test-Ban Treaty. READ MORE

4. 2. Surface Coatings as Xenon Diffusion Barriers for Improved Detection of Clandestine Nuclear Explosions

   Author : Lisa Bläckberg; Mattias Klintenberg; Henrik Sjöstrand; Anders Ringbom; Kai Vetter; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radioxenon; Gas Diffusion Barrier; Plastic Scintillator; Comprehensive Nuclear-Test-Ban Treaty; Atomic Layer Deposition; Al2O3; Molecular Dynamics; Light Transport;

   Abstract : This thesis investigates surface coatings as xenon diffusion barriers on plastic scintillators. The motivation for the work is improved radioxenon detection systems, used within the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT).One type of radioxenon detection systems used in this context is the Swedish SAUNA system.

5. 3. Systems Aspects of Increased Swedish Waste Incineration

   Author : Jenny Sahlin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological treatment; incineration tax; waste management; waste import; value of households’ time.; waste incineration; district heating; MSW; landfilling ban; recycling;

   Abstract : Abstract Recent bans on landfilling of combustible and organic waste in Sweden have resulted in an increase in alternative waste treatment, especially waste incineration with energy recovery. This thesis elucidates how the current increase in Swedish waste incineration affects and is affected by the two systems to which it belongs: the waste management and the energy systems. READ MORE

6. 4. Studies On Design of Near-Field Wireless-Powered Biphase Implantable Stimulators

   Author : Yonatan Habteslassie Kifle; Jacob Wikner; Atila Alvandpour; Sebastian Bader; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Portable and implantable electronics are becoming increasingly important in the healthcare sector. One of the challenges is to guarantee stable systems for longer periods of time. If we consider applications such as electrical nerve stimulation or implanted ion pumps, the requirements for, e.g. READ MORE

7. 5. Reliability, fatigue and mechanical characterization of lead-free solders for electronic packaging applications

   Author : Cristina Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability.; Isothermal mechanical fatigue; Tensile tests; Mechanical behavior; Electronics; Thermal fatigue; Lead-free solders; Low cycle fatigue;

   Abstract : The ever increasing amount of electronic waste, most of which ends up in landfills, has become a serious worldwide concern. In addition to this, the fact that Pb is highly toxic and harmful to humans has lead to the ban of this element from the electronics industry. READ MORE
