1. 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
2. Platinum Nanoparticles Prepared in Water-in-Oil Microemulsions -Particle Formation, Support Interaction and Catalytic Activity
Sammanfattning : .... LÄS MER
3. Flotation of silicate minerals : physico-chemical studies in the presence of alkylamines and mixed (cationic/anionic/non-ionic) collectors
Sammanfattning : The mechanism of adsorption of long chain alkyl primary amines and, co-adsorption of amines and alcohols on silicate minerals (quartz and feldspar) were studied using FTIR (DRIFT and IRRAS) and XPS spectroscopy methods. The spectroscopy data were correlated with zeta-potential and Hallimond flotation results. LÄS MER
4. Formation of mesostructured silica based on non-ionic interactions
Sammanfattning : Mesostructured silica is a material consisting of a silica matrix with an organization in the meso range of 2-50 nm. The silica matrix is most often amorphous while the organization, induced by a structure directing agent, may generate a long-range mesoorder. LÄS MER
5. Lubrication mechanism of hydrocarbon-mimicking ionic liquids
Sammanfattning : Lubrication is critical in order to achieve high efficiency and reliability of machine elements such as gears, bearings, and other moving mechanical assemblies (MMA). In space applications, tribological properties of lubricants are quickly growing more important. LÄS MER
