1. Biochemical conversion of biomass to biofuels : pretreatment–detoxification–hydrolysis–fermentation
Abstract : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. READ MORE

2. Deactivation of Catalysts and Reaction Kinetics for Upgrading of Renewable Oils
Abstract : The transport sector is one of the main contributors of greenhouse gas emissions in the world. Advanced biofuels from renewable oils can play a decisive role in reducing carbon emissions from the transport sector. Advanced biofuels from waste streams like tall oil, used cooking oil etc. READ MORE

3. Development of the Steam Pretreatment Process for Production of Ethanol from Lignocellulosic Biomass
Abstract : At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. READ MORE

4. Zeolite adsorbents and catalysts for the recovery and production of biochemicals
Abstract : Fossil based energy resources are dominating the world’s primary energy consumption for the last century. However, with decreasing crude oil reservoirs and the role they play in global warming by emitting greenhouse gases, the focus has been turned towards improved utilization of renewable resources and the need for new, sustainable fuels and chemicals is more urgent than ever.

5. Black & white or shades of grey : teachers perspectives on the role of nature of science in compulsory school science teaching
Abstract : Avhandlingen utforskar lärares perspektiv och förhandlingar gällande vilken roll “naturvetenskapens karaktär” (engelska ”nature of science”, NOS) kan spela i grundskolans NO-undervisning. Tidigare forskning har visat att NO-undervisning ofta har ett starkt fokus på naturvetenskapliga begrepp och strukturerade laborationer med ett implicit fokus på ”korrekta svar”. READ MORE
