16. Tunning Multicolor Light Emission in Lead-free Materials
Sammanfattning : Perovskites are a class of compounds with the general formula ABX3 and becoming increasingly attractive recently. Because this kind of material possesses various advantages such as abundant raw materials, easy synthesis, excellent photoelectric properties, and short production process. LÄS MER
17. On the Surface of Conducting Polymers : Electrochemical Switching of Color and Wettability in Conjugated Polymer Devices
Sammanfattning : Since the discovery in 1977 that conjugated polymers can be doped to achieve almost metallic electronic conduction, the research field of conducting polymers has escalated, with applications such as light emitting diodes, solar cells, thin film transistors, electrochemical transistors, logic circuits and sensors. The materials can be chemically modified during their synthesis in order to tailor the desired mechanical, electronic and optical properties of the final product. LÄS MER
18. Anticipation and Attention in Robot Control
Sammanfattning : Anticipatory and predictive models are becoming very important features of robot systems. This thesis investigates some aspects of predictive modeling. LÄS MER
19. Mind the Gap - Ethnography about the cultural reproduction of difference and disadvantage in urban education
Sammanfattning : This thesis examines cultural reproduction of difference and disadvantage in the pedagogical content and practices in urban education. Cultural differentiation is seen as a social and ideological practice that is constructed institutionally in the organization and structure of pedagogy. The objectives of this study are threefold.

20. Conjugated polymers on plasmonic metasurfaces for high contrast electronic paper in color
Sammanfattning : Electronic paper is the collective name of displays that, instead of emitting light, reflect the ambient light. These displays are known to have good readability in daylight and very low power consumption. However, there is a lack of electronic paper in color with high contrast and the ability to achieve video speed. LÄS MER
