  2. 1. A long journey from bioanode to biocathode

    Author : Soroush Saheb Alam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocathode; Bioelectrochemical system; Storage; Starvation; Microbial electrolysis cell; Bioanode; Microbial fuel cell; Mixed microbial communities; Hydrogenotrophic microorganisms;

    Abstract : Better utilization of renewable sources of energy and recovery of resources from waste streams are important challenges for researchers. Bioelectrochemical systems (BESs) are new technologies which e.g. could be used to produce green energy from waste sources or store renewable electricity as chemical fuels. READ MORE

  4. 2. Alkaline Urine Dehydration : how to dry source-separated human urine and recover nutrients?

    Author : Prithvi Simha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Human urine is a renewable resource from which water, nutrients and energy can be recovered and safely recycled. This thesis presents a novel on-site technology, called alkaline dehydration, for recovering nutrients from source-separated urine. READ MORE

  5. 3. Enzyme Immobilization in Mesoporous Silica

    Author : Hanna Gustafsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; immobilization; lipase; Mesoporous; particle morphology; feruloyl esterase; enzyme; encapsulation; silica; pore size; trypsin;

    Abstract : 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. READ MORE

  6. 4. Direct conversion of methane-to-methanol: transition-metal dimer sites in small-pore zeolites: First-principles calculations and microkinetic modeling

    Author : Unni Engedahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; partial methane oxidation; microkinetic modeling; SSZ-13; CHA; alloy; transition metals; zeolites; density functional theory;

    Abstract : Direct conversion of methane to methanol is a highly desired reaction. Partially oxidizing methane into a liquid fuel at ambient temperature and pressure would enable utilization of natural gas and biogas to a much larger extent than what is possible today. READ MORE

  7. 5. Multidimensional engineering for the production of fatty acid derivatives in Saccharomyces cerevisiae

    Author : Yating Hu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; Saccharomyces cerevisiae; fatty acid derivatives; metabolic engineering; tolerance; transporter;

    Abstract : Saccharomyces cerevisiae , also known as budding yeast, has been important for human society since ancient time due to its use during bread making and beer brewing, but it has also made important contribution to scientific studies as model eukaryote. The ease of genetic modification and the robustness and tolerance towards harsh conditions have established yeast as one of the most popular chassis in industrial-scale production of various compounds.
