6. Effects of Environment on Charge Recombination in Organo-Metal-Halide Perovskite Observed by Photoluminescence Microscopy and Spectroscopy
Sammanfattning : Organo-metal-halide (OMH) perovskites form a new class of materials withperovskite crystal structure ABX3 where A is an organic molecule, B is lead (Pb)and X is a halide atom (I or Br). OMH perovskite semiconductors have been widely used in photovoltaics due to their very strong absorption of sun light, very suitable electrical properties, and the ease of preparation. LÄS MER
7. The Physical Foundation of the Patterning of Physical Action Verbs : A Study of Chinese Verbs
Sammanfattning : This work is a study of verbal semantics with a focus on the discussion and illustration of the role of body parts and the semantic incorporation into verbal roots of the actions that involve various body parts. Following a general discussion of the basic issues of language construction and human body actions with the image schemas of force-dynamics presented in line with the framework of cognitive semantics, it is argued that the event structures of physical action verbs are not arbitrarily constructed but rather the constructions are built through systematic cognitive processes in relation to both human physical reality and concrete reality in the world.

8. The physical classroom environment : roles, conceptions, and preferences
Sammanfattning : The problem addressed in this thesis is that a considerable proportion of students around the world attend school in inadequate facilities, which is detrimental for the students’ learning outcome. The overall objective in this thesis is to develop a methodology, with a novel approach to involve teachers, to generate a valuable basis for decisions regarding design and improvement of physical school environment, based on the expressed needs for a specific school, municipality, or district as well as evidence from existing research.

10. Fluid Dynamics and Erosion in a Fluidized Bed for Energy Production. A Numerical and Experimental Study
Sammanfattning : This thesis presents an experimental and a numerical investigation of fluid dynamics and erosion of heat transfer tubes in fluidized beds for energy conversion. The objective is to obtain recommendations for suitable models that can be used to predict the fluid dynamics and material wastage of heat exchanger tubes in fluidized beds. LÄS MER
