2. 1. Fast pyrolysis of biomass : primary products and reaction pathways

   Author : David Usino; Tobias Richards; Weihong Yang; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast pyrolysis; Py-GC-MS FID; Primary reactions; Cellulose; Xylan; Lignin; Birch wood; Co-pyrolysis; Mahogany; Iroko; Palm kernel shell; Biomass blend; Biomass interaction; Pretreatment; Resource Recovery; Resursåtervinning;

   Abstract : Pyrolysis of biomass to produce liquid fuel and chemicals has been considered as an alternativeto fossil fuel because biomass has a lower environmental impact; moreover, it is renewable andcould be sustainable. However, the process of bio-oil production involves a series of complexchemical reactions which are dependent on the biomass feedstock and composition,temperature, heating rate as well as residence time.

4. 2. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases

   Author : Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; Biochemistry; biokemi;

   Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

5. 3. On boundary value problems for intracellular subdiffusion and signaling pathways, and for geometric flows

   Author : Tobias Gebäck; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; boundary value problems; diffusion-reaction equations; signaling pathways; anomalous diffusion; pseudo-differential equations; fluorescence correlation spectroscopy; immersed interface method; Boolean grids; mean curvature flow; pseudo-differential equations; boundary value problams; flourescence correlation spectroscopy;

   Abstract : The main part of this thesis concerns mathematical models for diffusion of proteins inside cells, including reactions between the proteins. Initially, such models are applied to describe signaling pathways in yeast cells, and the properties of the model are studied, especially in relation to models that do not include diffusion.

6. 4. Exploring Reaction Pathways in Li-ion Batteries with Operando Gas Analysis

   Author : Robin Lundström; Erik Berg; Reza Younesi; Isidora Cekic-Laskovic; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Online electrochemical mass spectrometry; Li-ion batteries; Solid electrolyte interphase; Reaction pathways; ; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : The reliance on Li-ion batteries is increasing as we transition from fossil fuels to renewable energy sources. Despite their widespread use, a gap remains in understanding certain processes within these batteries, especially regarding the solid electrolyte interphase (SEI) and the impact of side reactions on Li-ion batteries.

7. 5. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles

   Author : Johan Agrell; KTH; []
   Keywords : PEM fuel cells; hydrogen; methanol; reforming; oxidation; reaction pathways; carbon monoxide;

   Abstract : Vehicles powered by proton exchange membrane (PEM) fuelcells are approaching commercialisation. Being inherently cleanand efficient sources of power, fuel cells constitute asustainable alternative to internal combustion engines to meetfuture low-emission legislation. READ MORE
