1. 1. Probing the prospects for structural genomics : expression and characterization of human disease-related proteins in E. coli

   Författare :Niklas Hellgren; Torleif Härd; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi;

   Sammanfattning : Today a lot of research is directed towards the development of methods to make protein structure determination faster and more generalised. Automated, general methods for protein expression and purification, robotics for crystallisation and automatic methods for data collection will take structural biology into a new era, that of structural genomics.

3. 2. Sputtered Carbon Nitride Thin Films

   Författare :Niklas Hellgren; Bernd Schultrich; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The relation between the growth conditions and the film structure and properties of reactively magnetron sputtered carbon nitride CNx (0 ≤ x ≤ 0.6) thin films has been studied. The growth of CNx films has been studied when varying the process parameters, such as substrate temperature, N2 (partial) pressure and ion flux. LÄS MER

4. 3. Synthesis and characterization of magnetic nanolaminated carbides

   Författare :Andrejs Petruhins; Johanna Rosén; Per O. Å. Persson; Niklas K. Hellgren; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : MAX phases are a group of nanolaminated ternary carbides and nitrides, with a composition expressed by the general formula Mn+1AXn (? = 1 − 3), where M is a transition metal, A is an A-group element, and X is carbon and/or nitrogen. MAX phases have attracted interest due to their unique combination of metallic and ceramic properties, related to their inherently laminated structure of a transition metal carbide (Mn+1Xn) layer interleaved by an A-group metal layer.
