1. Enzyme Immobilization in Mesoporous Silica
Sammanfattning : Catalysts are widely used in many industries for production of chemicals, pharmaceuticals, fuels and energy. There is a need for more sustainable production processes, with reduced energy and raw material consumption together with a reduction in waste and toxic by-products. LÄS MER
2. Platinum Nanoparticles Prepared in Water-in-Oil Microemulsions -Particle Formation, Support Interaction and Catalytic Activity
Sammanfattning : .... LÄS MER
3. Immobilization of feruloyl esterases in mesoporous silica
Sammanfattning : Feruloyl esterases are a class of enzymes that can be used as biocatalysts for the modification of bioactive hydroxycinnamic acids. In industry, enzyme immobilization is often necessary to stabilize the enzymes and to allow their reuse. LÄS MER
4. Enzyme immobilization in mesoporous silica
Sammanfattning : Enzymes are highly effective and versatile biological catalysts, with a high chemo-, stereo- and regioselectivity while operating under mild conditions, such as physiological temperature and pH and atmospheric pressure. Therefore, enzymes are a sustainable alternative to conventional catalysts in organic synthesis processes. LÄS MER
5. Diatom-rich sediment formation in lakes
Sammanfattning : Unicellular photosynthetic golden algae called diatoms are one of the most abundant silicifying organisms. Diatoms take up silicon and build their frustules, in the form of biogenic silica (BSi), which have high preservation potential, and thus are found in sediments. LÄS MER
