Photoinduced interfacial electron transfer and lateral charge transport in molecular donor–acceptor photovoltaic systems

Jacques-Edouard Moser, Arianna Marchioro, Jan Cornelius Brauer, Elham Ghadiri, Angela Punzi

Nanostructured liquid|solid and solid|solid bulk heterojunctions designed for the conversion of solar energy offer ideal models for the investigation of light-induced ET dynamics at surfaces. Despite significant study of processes leading to charge generat ...

The Graphene-Gold Interface and Its Implications for Nanoelectronics

Klaus Kern, Marko Burghard, Ravi Shankar Sundaram

We combine optical microspectroscopy and electronic measurements to study how gold deposition affects the physical properties of graphene. We find that the electronic structure, the electron-phonon coupling, and the doping level in gold-plated graphene are ...

Structure Determination and Compositional Modification of Body-Centered Tetragonal PX-Phase Lead Titanate

Nava Setter, Kurt Schenk, Silviu Cosmin Sandu, Alexandra Sarabando de Carvalho, Jin Wang

The fibrous PX-phase of lead titanate (PT), which can be synthesized by a hydrothermal method, has been studied to clarify its structural aspects on the atomic level. By combining synchrotron X-ray diffraction and electron microscope analysis with a first- ...

Radiative Engineering of NanoAntenna Arrays for Ultra-Sensitive Vibrational Spectroscopy of Proteins

Hatice Altug, Shyamsunder Erramilli, Mi Kyung Hong

Infrared absorption spectroscopy offers direct access to the vibrational signatures of molecular structure. Although absorption cross sections are nearly 10 orders of magnitude larger than the Raman cross sections, they are small in comparison with those o ...

Molecular dissection of telomeric repeat-containing RNA biogenesis unveils the presence of distinct and multiple regulatory pathways

Joachim Lingner, Antonio Porro, Sascha Feuerhahn

Telomeres are transcribed into telomeric repeat-containing RNA (TERRA), large, heterogeneous, noncoding transcripts which form part of the telomeric heterochromatin. Despite a large number of functions that have been ascribed to TERRA, little is known abou ...

Oxygen permeation, mechanical and structural properties of multilayer diffusion barrier coatings on polypropylene

Yves Leterrier, Judith Helen Waller

To improve temperature durability for autoclaving of SiOx diffusion barrier coatings on polypropylene, plasma polymerized hexamethyldisiloxane (pp-HMDSO) is applied by plasma enhanced chemical vapour deposition as interlayer material and compared with resu ...

Adhesion of thermoplastic polyurethane elastomer onto galvanized steel

Véronique Michaud, Basile Golaz

When a thermoplastic polyurethane elastomer (TPU) is applied onto galvanized steel by a hot melt process, the subsequent adhesion and its durability are very sensitive to the chemical bonds created at the interface. The effects of several surface treatment ...

Identification and characterization of novel classes of macrophage migration inhibitory factor (MIF) inhibitors with distinct mechanisms of action

Hilal Lashuel, Bruno Claude Daniel Fauvet, Magdalena Zweckstetter, Hajer Ouertatani-Sakouhi, Farah El Turk, Min Kyu Cho

Macrophage migration inhibitory factor (MIF), a proinflammatory cytokine, is considered an attractive therapeutic target in multiple inflammatory and autoimmune disorders. In addition to its known biologic activities, MIF can also function as a tautomerase ...

Orbital characterization of iron-pnictide high-temperature superconductors by angle resolved photoemission spectroscopy

Laurent Cevey

The electronic structure of the optimally hole-doped pnictide compound Ba0:6K0:4Fe2As2 was obtained and studied by angle resolved photoemission spectroscopy (ARPES). The light polarization dependence of the bands is explained by the selection rules contain ...
