The thesis presents experimental results on the growth and magnetism of metallic nanostructures on the vicinal Pt surface. The aim of the research project consists of two parts: First, to find conditions for growing nanostructures of dimensionalities from ...
We demonstrate herein that human macrophage migration inhibitory factor (MIF), a pro-inflammatory cytokine expressed in the brain and not previously considered to be amyloidogenic, forms amyloid fibrils similar to those derived from the disease associated ...
The surface plasmon enhanced hyper-Rayleigh scattering light collected from an aqueous solution of gold nanorods is reported. A non negligible part of the signal is attributed to a photoluminescence background attributed to the electron–hole recombination ...
A new 9.9 kb catabolic transposon, Tn-Dha1, containing the gene responsible for tetrachloroethene (PCE) reductive dechlorination activity, was isolated from Desulfitobacterium hafniense strain TCE1. Two fully identical copies of the insertion sequence ISDh ...
We use sum-frequency generation spectroscopy (SFG) in the infrared 2800–3000 cm−1 spectral range and UV–vis spectroscopy (transmission) in the 450–650 nm spectral range in order to characterize vibrational and electronic properties of various interfaces co ...
We report on the progress in the growth of highly reflective AlInN-GaN distributed Bragg reflectors deposited by metalorganic vapor phase epitaxy. Al1-xInxN layers with an In content around x similar to 0.17 are lattice-matched to GaN, thus avoiding strain ...
We performed bulk-sensitive x-ray absorption (XAS) in the partial fluorescence yield (PFY) mode, and resonant x-ray emission (RXES) measurements of the solid solution Sc (7 at.%):Ce at the Ce L-3 (2p-->5d) and M-4,M-5 (3d-->4f) absorption edges. We deduce ...
A new cobalt(II) phosphate compd. has been synthesized using high-temp. flux methods in the CsCl/NaCl media at 650°C. The title compd., Na3CsCo7(PO4)6, forms vibrant purple plate crystals. It crystallizes in a monoclinic space group C2/c (no. 15) with the ...
This study investigates the structure and organization of a series of hybrid diblock copolymers based on polyethylene glycol) (PEG) and peptide sequences inspired by the coiled coil protein folding motif. Circular dichroism spectroscopy and analytical ultr ...
The invention concerns a combinatorial method for the generation of new split-protein sensors, and its application towards the (beta/alpha)8-barrel enzyme N-(5'-phosphoribosyl)-anthranilate isomerase Trp1p from Saccharomyces cerevisiae is demonstrated. The ...
