3. 17. Nucleic acid analysis tools : Novel technologies and biomedical applications

   Författare :Iván Hernández-Neuta; Mats Nilsson; Frank Bier; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nucleic acid analysis; padlock probes; selector probes; rolling circle amplification; microfluidics; single-molecule detection; digital quantification; fluorescence microscopy; mobile phone microscopy; molecular diagnostics; virology; Biochemistry; biokemi;

   Sammanfattning : Nucleic acids are fundamental molecules of living organisms functioning essentially as the molecular information carriers of life. From how an organism is built to how it responds to external conditions, all of it, can be found in the form of nucleic acid sequences inside every single cell of every life form on earth. LÄS MER

4. 18. Crystallization of Metal Fluoride Hydrates from Mixed Acid Solutions

   Författare :Kerstin Forsberg; Åke Rasmuson; Alison Lewis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crystallization; crystal growth; b-FeF3.3H2O; iron fluoride trihydrate; CrF3.3H2O; pickling; pickle bath; hydrofluoric acid; nitric acid; stainless steel; Chemical engineering; Kemiteknik;

   Sammanfattning : In this work crystal growth and nucleation of b-FeF3×3H2O and crystallization of chromium (III), iron (III) and nickel (II) fluoride hydrates from mixed acid (1-3 mol/kg HNO3 and 1-6 mol/kg free HF) have been investigated. The solubility of b-FeF3×3H2O has been determined in solutions of different hydrofluoric acid (1-7mol/ kg) and nitric acid (0-7mol/ kg) concentrations at 30, 40 and 50°C. LÄS MER

5. 19. Formic and Levulinic Acid from Cellulose via Heterogeneous Catalysis

   Författare :Johan Ahlkvist; Jyri-Pekka Mikkola; Riitta Keiski; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Levulinic acid; formic acid; Amberlyst 70;

   Sammanfattning : The chemical industry of today is under increased pressure to develop novel green materials, bio-fuels as well as sustainable chemicals for the chemical industry. Indeed, the endeavour is to move towards more eco-friendly cost efficient production processes and technologies and chemical transformation of renewables has a central role considering the future sustainable supply of chemicals and energy needed for societies.

7. 20. Physical properties and crystallization of theophylline co-crystals

   Författare :Shuo Zhang; Åke Rasmuson; Per Svensson; Mårten Behm; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Theophylline; oxalic acid; glutaric acid; maleic acid; co-crystal; decomposition temperature; melting temperature; solubility; crystallization; Molecular transport processes in chemical process engineering; Molekylära transportprocesser i kemisk processteknik;

   Sammanfattning : This work focuses on the physical properties and crystallization of theophyline co-crystals. Co-crystals of theophylline with oxalic acid, glutaric acid and maleic acid have been investigated. The DSC curves of these co-crystals show that their first endothermic peaks are all lower than the melting temperature of theophylline. LÄS MER
