Cloaking via anomalous localized resonance for doubly complementary media in the quasistatic regime

This paper is devoted to the study of cloaking via anomalous localized resonance (CALR) in the two- and three-dimensional quasistatic regimes. CALR associated with negative index materials was discovered by Milton and Nicorovici [21] for constant plasmonic ...

Time-dependent density functional theory molecular dynamics simulation of doubly charged uracil in gas phase

Ursula Röthlisberger, Ivano Tavernelli, Pablo Lopez Tarifa

We use time-dependent density functional theory and Born-Oppenheimer molecular dynamics methods to investigate the fragmentation of doubly ionized uracil in gas phase. Different initial electronic excited states of the dication are obtained by removing ele ...

Renormalization of myoglobin-ligand binding energetics by quantum many-body effects

Cédric Weber

We carry out a first-principles atomistic study of the electronic mechanisms of ligand binding and discrimination in the myoglobin protein. Electronic correlation effects are taken into account using one of the most advanced methods currently available, na ...

Characterization of solvent-filled polyurethane/urea-formaldehyde core-shell composites

Véronique Michaud, Sam Neuser, Erica Manfredi

Encapsulation of liquid phases is a crucial step in many self-healing material systems where a healing agent has to be protected during processing and then released during a damage event. In this work, the mechanical properties of polyurethane (PU) reinfor ...

The nature of the quasiparticles in two benchmark transition metal oxides

Simon Karl Moser

Transition metal oxides (TMOs) are emerging strong players in many domains, ranging from superconductivity, to microelectronics to spintronics to light harvesting for photovoltaics. Beyond their non-toxicity, low corrosiveness and low price, they exhibit a ...

Unraveling the Core-Shell Structure of Ligand-Capped Sn/SnOx Nanoparticles by Surface-Enhanced Nuclear Magnetic Resonance, Mossbauer, and X-ray Absorption Spectroscopies

David Lyndon Emsley, Aaron James Rossini

A particularly difficult challenge in the chemistry of nanomaterials is the detailed structural and chemical analysis of multicomponent nano-objects. This is especially true for the determination of spatially resolved information. In this study, we demonst ...

Influence of composition on the morphology of polyurethane/acrylic latex particles and adhesive films

John Christopher Plummer, Costantino Creton

Polyurethane (PU)/acrylic hybrid particles with different PU contents were synthesized by miniemulsion polymerization and subsequently dried to give solid adhesive films. The morphologies of the particles and the morphologies and mechanical properties of t ...

Magnetic field-tuned localization of the5f-electrons in URu2Si2

Philip Johannes Walter Moll

We report Shubnikov-de Haas oscillation measurements within the high magnetic field (μ0H>39 T) magnetically polarized regime of URu2Si2, made possible using mesoscopic samples prepared by means of focused ion beam lithography. A significant change in the F ...

First principles study of As 2p core-level shifts at GaAs/Al2O3 interfaces

Alfredo Pasquarello, Giacomo Francesco Leonardo Miceli

Arsenic 2p core-level shifts at GaAs/Al2O3 interfaces are determined with respect to bulk GaAs through density functional calculations. Atomistic interface models are constructed in which As atoms are found in various chemical environments. Both Ga-termina ...

Low-temperature spin dynamics of a valence bond glass in Ba

Henrik Moodysson Rønnow, Julian Piatek

We carried out ac magnetic susceptibility measurements and muon spin relaxation spectroscopy on the cubic double perovskite Ba2YMoO 6, down to 50 mK. Below ∼1 K the muon relaxation is typical of a magnetic insulator with a spin-liquid type ground state, i. ...
