1. 1. Microsensors for in situ electron microscopy applications

   Författare :Alexandra Nafari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive read-out; Microsensors; In situ TEM; TEM-AFM; TEM-Nanoindenter; AFM; nanoscale characterisation; MEMS; Nanoindentation; piezoresistive read-out;

   Sammanfattning : With the ongoing miniaturisation of devices, the interest in characterising nanoscale physical properties has strongly increased. To further advance the field of nanotechnology new scientific tools are required. LÄS MER

3. 2. Citrus Waste Biorefinery: Process Development, Simulation and Economic Analysis

   Författare :Mohammad Pour Bafrani; Mohammad Pourbafrani; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process simulation; encapsulated yeast; Citrus wastes; economic analysis; computational fluid dynamic simulation; pectin; limonene; methane; ethanol;

   Sammanfattning : The production of ethanol and other sustainable products including methane, limonene and pectin from citrus wastes (CWs) was studied in the present thesis. In the first part of the work, the CWs were hydrolyzed using enzymes – pectinase, cellulase and β-glucosidase – and the hydrolyzate was fermented using encapsulated yeasts in the presence of the inhibitor compound ‘limonene’.

4. 3. Conversion processes for biofuel production

   Författare :Jerry Luis Solis; Yohannes Kiros; Mohammad Taherzadeh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Second-generation biofuels; biodiesel; heterogeneous catalysts; non-edible oils; ethanol; residual biomass; native yeast strains.; Andra generationens biobränslen; biodiesel; heterogena katalysatorer; oätliga oljor; etanol; rester av biomassa; naturliga jäststammar; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

   Sammanfattning : Despite the global positive impacts of soybean-, maize- and sugarcane-based (first-generation) liquid biofuels, several drawbacks pertaining to increased use of agricultural land, causing deforestation in some countries and extensive practice of fertilizers have been observed. As a result, developing advanced (second- and third-generation) liquid biofuels have been identified as better alternatives and are considered to be of great importance in the future. LÄS MER

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

   Författare :Yating Hu; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 5. Genetic engineering of Yarrowia lipolytica for the sustainable production of food oils

   Författare :Oliver Konzock; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triacyclglycerols; RNA-seq; tolerance; cocoa butter; hydrolysate; yeast; desaturase; filamentation;

   Sammanfattning : The human population and its demand for food oils is constantly growing. However, increasing food oil production currently requires the deforestation of mostly tropical rainforests to allow the plantation of oil crops. LÄS MER
