Sammanfattning : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. LÄS MER
2. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER
3. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass
Sammanfattning : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. LÄS MER
4. Ozonskiktet och risksamhället : En studie av den svenska politiska diskussionen rörande ozonskiktet 1968-1992
Sammanfattning : This thesis examines the development of the Swedish political discussion concerning the ozonelayer between 1968 and 1992. The analysis is based on the assumption that the threats against the ozone layer confronted the political system with an issue that called for new ways of thinking about environmental problems.

Sammanfattning : The electric vehicle itself today outlives its battery, necessitating battery replacement. Lithium titanium oxide (LTO) has, in this context, been suggested as a new anode material in heavy electric vehicle applications due to intrinsic properties regarding safety, lifetime and availability.
