2. 6. Characterization of ATP-dependent protein dynamics under native-like conditions

   Author : Harsha Ravishankar; Magnus Andersson; Hans Wolf-Watz; Lise Arleth; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; structural dynamics; ATPases; MD simulations; X-ray scattering; FTIR spectroscopy; ATP; TR-XSS; structural biology.; Biochemistry; biokemi;

   Abstract : Proteins are biological macromolecules capable of accelerating biochemical reactions. To accomplish this, proteins undergo changes in their molecular structure. Advances in structural biology have resulted in ever-increasing numbers of high-resolution protein structures. READ MORE

4. 7. Engineering of Human Fetal Hemoglobin

   Author : Karin Kettisen; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fetal hemoglobin; protein engineering; recombinant protein production; protein purification; chromatography; oxygen carrier; redox reactions; net surface charge; DNA cleavage;

   Abstract : In blood, the oxygen-transporting protein hemoglobin (Hb) governs the oxygenation of cells and tissues. Naturally, this protein has claimed a place in the center of the research field of artificial oxygen therapeutics. READ MORE

5. 8. 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.

7. 10. New C-C coupling Reactions Enabled by Main-group Organometallics

   Author : Kilian Colas; Abraham Mendoza; David Procter; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; C-C coupling; organometallics; aluminum; magnesium; Grignard; turbo-Hauser-bases; piperazines; sulfur; ketones; organisk kemi; Organic Chemistry;

   Abstract : The carbon-carbon bond has always been at the very core of chemical research. Strategies for the creation of C−C bonds are one of the keys to the construction game that organic chemists play with the building blocks provided by Nature, with the ultimate goal of producing useful molecular structures that will serve society as medicines, materials, imaging tools, catalysts, and ligands (to mention but a few).
