16. QCM-based sensing using biological and biomimetic interfaces
Sammanfattning : The objective of this thesis was to explore novel approaches for studying molecular recognition at biological and biomimetic surfaces using the quartz crystal microbalance (QCM) biosensor technique. The first two papers focused on the synthesis and study of biotin selective polymer films prepared using the molecularly imprinted polymer (MIP) technique. LÄS MER
17. Värmebevarande insatser utifrån patientens och operationsteamets perspektiv
Sammanfattning : Aim: The overall aim was to map and describe experiences of heat conservationmeasures (HCM) for the patient in connection with surgery from the patientʼsand the surgical teamʼs perspectives. The four studies aimed to: determinewhether nurse anesthetists have access to, knowledge of, and adhere torecommended guidelines to maintain normal body temperature during theperioperative period (I), describe the patientʼs lived experience of warmth andcoldness in connection with surgery (II), describe the nurse anesthetistʼsperceptions of heat conservation measures in connection with surgery (III),describe the surgical team memberʼs experience of communication regardingheat conservation measures during surgery (IV).

18. Si negative electrodes for Li-ion batteries : Aging mechanism studies by electrochemistry and photoelectron spectroscopy
Sammanfattning : This thesis is focusing on the challenges when using Si as a possible new negative electrode material in Li-ion batteries. The overall aim is to contribute to a general understanding of the processes in the Si electrode, to identify aging mechanisms, and to evaluate how they influence the cycling performance. LÄS MER
19. LiFeSO4F as a Cathode Material for Lithium-Ion Batteries : Synthesis, Structure, and Function
Sammanfattning : In this thesis, two recently discovered polymorphs of LiFeSO4F, adopting a tavorite- and triplite-type structure, were investigated as potential candidates for use as cathode materials in Li-ion batteries. The studies aimed at enriching the fundamental understanding of the synthetic preparations, structural properties, and electrochemical functionality of these materials. LÄS MER
20. En bild säger mer än tusen ord : Barns perspektiv, positioner och påverkansmöjligheter i förskolans dokumentationspraktik
Sammanfattning : The overall aim of this thesis is to examine children's perspectives, positions and possibilities for participation in Swedish preschool documentation practice. The empirical data consists of 1575 photographs from six preschool classes located in different suburban areas. LÄS MER
