2. 26. Sustainable recycling of Li-ion batteries

   Author : Jędrzej Piątek; Adam Slabon; Tetyana Budnyak; Reza Younesi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; batteries; recycling; metal recovery; adsorption; electrochemistry; oorganisk kemi; Inorganic Chemistry;

   Abstract : Lithium-ion batteries (LIBs) play a key role in today’s energy storage sector, finding applications in everyday use electronic devices, like smartphones, laptops or electric vehicles. Despite very good properties, such as high electric capacity and high number of charge-discharge cycles, eventually each battery in the world will be disposed and stored in a landfill, waiting for the opportunity to be recycled.

4. 27. Cell models for evaluation of adult and developmental neurotoxicity : Focus on acrylamide

   Author : Kristina Attoff; Anna Forsby; Åsa Fex-Svenningsen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Abstract : This thesis is aimed at summarizing some of the alternative in vitro methods and models that have been used to study both adult and developmental neurotoxicity (DNT), and also to pinpoint some of the important aspects of using alternative in vitro methods. The aim of the papers included in this thesis was to challenge the hypothesis that neurotoxicity and DNT of chemicals can be studied using robust endpoints for proliferation and neural differentiation, such as neurite outgrowth, mRNA expression and protein expression, in two different cell lines.

5. 28. Experimental investigations of ageing of commercial BEV Li-ion batteries

   Author : Kristian Bartholdsson Frenander; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon oxide; lithium plating; ageing; Physics-based modelling; Electric Vehicles; Lithium Ion Batteries; lifetime; NCA; State of Charge;

   Abstract : The rapid development of lithium-ion batteries has enabled changes in widespread applications ranging from portable electronics to electric vehicles and large scale grid energy storage. However, battery ageing remain a challenge in all these applications, and this thesis seeks to contribute to the understanding of Li-ion battery degradation. READ MORE

6. 29. Detailed simulation of heterogeneous wireless sensor networks

   Author : Joakim Eriksson; Thiemo Voigt; Per Gunningberg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Abstract : Wireless sensor networks consist of many small nodes. Each node has a small microprocessor, a radio chip, some sensors, and is usually battery powered which limits network lifetime. Applications of wireless sensor networks range from environmental monitoring and health-care to industrial automation and military surveillance. READ MORE

7. 30. Hearing and cognition in speech comprehension. Methods and applications

   Author : Mathias Hällgren; Stig Arlinger; Birgitta Larsby; Arne Leijon; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; physiology; cognition; cognition disorders; dichotic listening tests; hearing loss; sensorineural; neuropsychological tests; speech perception; Audiology; Audiologi;

   Abstract : Central auditory processing is complex and can not be evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests and cognitive tests that tax functions important for speech processing. READ MORE
