1. 21. Characterization and preparation of lightweight silica based ceramics for building applications

   Författare :Edwin Escalera; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

   Sammanfattning : Bolivia is a country with considerable quantities of non-metallic resources. Some important deposits of these resources are located in the high and cold Altiplano as well as in the tropical areas. These deposits are not being exploited industrially but both areas have production of some ceramics in a handmade and empiric way. LÄS MER

3. 22. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

   Författare :Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; proteins; circularity; superabsorbents; sustainability; acylation; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. LÄS MER

4. 23. Development and Validation of HPLC Methods for Analytical and Preparative Purposes

   Författare :Johan Lindholm; Torgny Fornstedt; Karin Caldwell; Karl-Gustaf Wahlund; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; High performance liquid chromatography HPLC ; Analytical biotechnology; Sample preparation; Diode-array-detection DAD ; Mass spectrometry MS ; Validation; Preparative chromatography; Competitive isotherm parameters; Perturbation peak PP method; Kemi; Chemistry; Kemi;

   Sammanfattning : This thesis concerns the development and validation of high performance liquid chromatography (HPLC) methods aimed for two industrially important areas: (i) analysis of biotechnological synthesis and (ii) determination of adsorption isotherm parameters. There is today a lack of detailed recommendations for analytical procedures in the field of biotechnological production of drugs. LÄS MER

5. 24. A Study of Different Methods for Inclusion Characterization towards On-line use during Steelmaking

   Författare :Diana Janis; Pär Jönsson; Lauri Holappa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; on-line method; PDA OES; electrolytic extraction; inclusions; clusters; nozzle clogging; secondary steelmaking;

   Sammanfattning : The interest of gaining on-line information related to non-metallic inclusions during the steelmaking process has recently increased due to the development as well as the promising results of the Pulse Distribution Analysis with Optical Emission Spectroscopy method (PDA/OES). Even though, the time from sampling to presented results on inclusions is only about 5-10 minutes, the method has also shown limitations with respect to the determination of some inclusion characteristics.

7. 25. Improving Productivity and Enzyme Stability Through Process Design: Lipase-catalysed Synthesis of Epoxides and Esters

   Författare :Anna Hagström; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Interest in sustainable development has increased throughout society during the past decades, and the chemical industry is no exception. The appeal for renewable raw materials has consequently increased and has paved the way for the implementation of industrial biotechnology. LÄS MER
