The Metallofullerene Field-Induced Single-Ion Magnet HoSc2N@C-80
The low-temperature magnetic properties of the endohedral metallofullerene HoSc2N@C-80 have been studied by superconducting quantum interference device (SQUID) magnetometry. Alternating current (ac) susceptibility measurements reveal that this molecule exh ...
Wiley-Blackwell2014UPTAKE AND INTRACELLULAR TRAFFICKING OF SUPERPARAMAGNETIC IRON OXIDE NANOPARTICLES (SPIONs) IN PLANTS
The uptake and movement of iron nanoparticles in elodea plants have been detected by the ESR method. This method is applied for the first time for the monitoring of the translocation, movement and uptake iron nanoparticles in plant organs. Exposition of st ...

Transverse and longitudinal relaxation times (T11 and T1) have been widely exploited in NMR to probe the binding of ligands and putative drugs to target proteins. We have shown recently that long-lived states (LLS) can be more sensitive to ligand binding. ...

Theo Lasser, Heinrich Hofmann, Marcel Leutenegger, Arno Pino Bouwens, Lionel André Maurizi, Daniel Pawel Szlag, Stéphane Broillet
Optical coherence correlation spectroscopy (OCCS) allows studying kinetic processes at the single particle level using the backscattered light of nanoparticles. We extend the possibilities of this technique by increasing its signal-to-noise ratio by a fact ...
Optical Society of America2014On-Chip Fabrication of Paclitaxel-Loaded Chitosan Nanoparticles for Cancer Therapeutics
Philippe Renaud, Arnaud Bertsch, Mohammad Mahdi Hasani-Sadrabadi, Shahin Bonakdar, Fatemeh Sadat Majedi, Jules John Vandersarl
The use of solvent-free microfluidics to fine-tune the physical and chemical properties of chitosan nanoparticles for drug delivery is demonstrated. Nanoparticle self-assembly is driven by pH changes in a water environment, which increases biocompatibility ...
Wiley-Blackwell2014Electronic structure of KTi(SO4)(2)center dot H2O: An S=1/2 frustrated chain antiferromagnet
Henrik Moodysson Rønnow, Julian Piatek, Goran Nilsen
The compound KTi(SO4)(2)center dot H2O was recently reported as a quasi-one-dimensional spin-1/2 compound with competing antiferromagnetic nearest-neighbor exchange J(1) and next-nearest-neighbor exchange J(2) along the chain with a frustration ratio alpha ...
American Physical Society2013Growth and Magnetism of Nanostructures Investigated by STM, MOKE, and XMCD
This thesis presents our studies on nanostructures growth and magnetism, mainly based on scanning tunneling microscopy (STM), magneto-optical Kerr effect (MOKE), and x-ray magnetic circular dichroism (XMCD) measurements. In most of these experiments, nanos ...
EPFL2013Superparamagnetic anisotropic elastomer connectors exhibiting reversible magneto-piezoresistivity
An anisotropic magnetorheological composite formed by dispersions of silver-covered magnetite microparticles (Fe3O4@Ag) in polydimethylsiloxane (PDMS) displaying electrical conduction only in one preferred direction is presented. A set-up for applying and ...
Elsevier2013Magnetism of Single Adatoms and Small Adsorbed Clusters Investigated by Means of Low-Temperature STM
This thesis works reports on the magnetic properties of single transition metal atoms and hydrogenated compounds adsorbed on crystal surfaces. It is an experimental study, based on scanning tunneling microscopy (STM), initiated by the project of demonstrat ...
EPFL2013Phase diagram with an enhanced spin-glass region of the mixed Ising–XY magnet LiHoxEr1-xF4
