26 p, 1.6 MB In-depth characterization of as-deposited and annealed Fe-W coatings electrodeposited from glycolate-citrate plating bath / Mulone, Antonio (Chalmers University of Technology) ; Nicolenco, Aliona (Vilnius University) ; Hoffmann, Volker (Leibniz Institute for Solid State and Materials Research Dresden) ; Klement, U. (Chalmers tekniska högskola) ; Tsyntsaru, N. (Vilniaus Universitetas) ; Cesiulis, Henrikas (Vilniaus Universitetas)
Fe-W coatings with 4, 16 and 24 at. % of W were electrodeposited under galvanostatic conditions from a new environmental friendly Fe(III)-based glycolate-citrate bath. This work aims to find correlations between composition including the light elements, internal structure of the electrodeposited Fe-W alloys and functional properties of material. [...]

Departament de Bioquímica i de Biologia Molecular) ; Peralvarez-Marin, Alex (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular)
Bacteriorhodopsin has a polar cluster of amino acids surrounding the retinal molecule, which is responsible for light harvesting to fuel proton pumping. From our previous studies, we have shown that threonine 90 is the pivotal amino acid in this polar cluster, both functionally and structurally. [...]
