Cellulose Nanocrystals with Tethered Polymer Chains: Chemically Patchy versus Uniform Decoration

Harm-Anton Klok, Alke Fink, Justin Orazio Zoppe, Théo Gaston Gérard Lachat, Alix Vaimiti Marie Dupire

The site-specific surface modification of colloidal substrates, yielding "patchy" nanoparticles, is a rapidly expanding area of research as a result of the new complex structural hierarchies that are becoming accessible to chemists and materials scientists ...

Complex Magnetic Exchange Coupling between Co Nanostructures and Ni(111) across Epitaxial Graphene

Harald Brune, François Patthey, Stefano Rusponi, Marina Pivetta, Pietro Gambardella, Fabio Donati

We report on the magnetic coupling between isolated Co atoms as well as small Co islands and Ni(111) mediated by an epitaxial graphene layer. X-ray magnetic circular dichroism and scanning tunneling microscopy combined with density functional theory calcul ...

Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Julien Perruisseau-Carrier, Michele Tamagnone

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Photo-induced oxidation of the uniquely liganded heme f in the cytochrome b(6)f complex of oxygenic photosynthesis

Frank van Mourik, Andre Al Haddad, Adrien Alexis Paul Chauvet, Rachna Agarwal

The ultrafast behavior of the ferrous heme f from the cytochrome b(6)f complex of oxygenic photosynthesis is revealed by means of transient absorption spectroscopy. Benefiting from the use of microfluidic technologies for handling the sample as well as fro ...

Molecular Engineering of Potent Sensitizers for Very Efficient Light Harvesting in Thin-Film Solid-State Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Chenyi Yi, Norman Pellet, Yelin Hu, Marcel Roland Schreier, Xiaoyu Zhang, Yi Xu

Dye-sensitized solar cells (DSSCs) have shown significant potential for indoor arid building integrated photovoltaic applications. Herein we present three new D-A-pi-A organic sensitizers, XY1, XY2, and XY3, that exhibit high molar extinction coefficients ...

Interfacial properties of LaMnO3/LaNiO3 superlattices grown along (001) and (111) orientations

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

We have employed x-ray absorption spectroscopy and x-ray magnetic circular dichroism (XMCD) at the Ni andMn L-3,L-2 edges in LaMnO3/LaNiO3 superlattices grown along (001) and (111) orientations. Our results show a significant XMCD signal and thus the prese ...

Towards enabling femtosecond helicity-dependent spectroscopy with high-harmonic sources

Christoph Peter Hauri, Fernando Ardana Lamas

Recent advances in high-harmonic generation gave rise to soft X-ray pulses with higher intensity, shorter duration and higher photon energy. One of the remaining shortages of this source is its restriction to linear polarization, since the yield of generat ...

Magnetic moments in chemically ordered mass-selected CoPt and FePt clusters

Luca Gragnaniello

By combining high photon flux and chemical selectivity, X-ray absorption spectroscopy and X-ray magnetic circular dichroism (XMCD) have been used to study the magnetism of CoPt and FePt clusters before and after their transition to the chemically ordered L ...

Surface Aligned Magnetic Moments and Hysteresis of an Endohedral Single-Molecule Magnet on a Metal

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

The interaction between the endohedral unit in the single-molecule magnet Dy2ScN@C-80 and a rhodium (111) substrate leads to alignment of the Dy 4f orbitals. The resulting orientation of the Dy2ScN plane parallel to the surface is inferred from comparison ...
