Surface Reaction Barriometry: Methane Dissociation on Flat and Stepped Transition-Metal Surfaces

Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick, Francesco Nattino

Accurately simulating heterogeneously catalyzed reactions requires reliable barriers for molecules reacting at defects on metal surfaces, such as steps. However, first- principles methods capable of computing these barriers to chemical accuracy have yet to ...

Observation of the 1S–2S transition in trapped antihydrogen

Shirit Cohen

The spectrum of the hydrogen atom has played a central part in fundamental physics over the past 200 years. Historical examples of its importance include the wavelength measurements of absorption lines in the solar spectrum by Fraunhofer, the identificatio ...

Thermodynamic anomaly above the superconducting critical temperature in the quasi-one-dimensional superconductorTa4Pd3Te16

Philip Johannes Walter Moll

We study the intrinsic electronic anisotropy and fermiology of the quasi-one-dimensional superconductor Ta4Pd3Te16. Below T∗=20 K, we detect a thermodynamic phase transition that predominantly affects the conductivity perpendicular to the quasi-one-dimensi ...

Guanidinium can both Cause and Prevent the Hydrophobic Collapse of Biomacromolecules

Halil Ibrahim Okur

A combination of Fourier transform infrared and phase transition measurements as well as molecular computer simulations, and thermodynamic modeling were performed to probe the mechanisms by which guanidinium (Gnd(+)) salts influence the stability of the co ...

Effects of partial crystallization in Pt-Si-B-based bulk metallic glasses on glass transition and crystallization of the remaining amorphous matrix

Ludger Weber, Hamed Kazemi, Cyrill Werner Cattin, Gilles Hodel

The influence of partial crystallization on the evolution of the characteristic temperatures, i.e. of the glass transition and the onset of crystallization, the density, and the mechanical properties of the bulk metallic glass Pt(49.95)Si(6)AB(24)Ge(3)Cu(1 ...

Constant-pressure nested sampling with atomistic dynamics

Robert John Nicholas Baldock

The nested sampling algorithm has been shown to be a general method for calculating the pressure-temperature-composition phase diagrams of materials. While the previous implementation used single-particle Monte Carlo moves, these are inefficient for conden ...

Van der Waals MoS2/VO2 heterostructure junction with tunable rectifier behavior and efficient photoresponse

Olivier Martin, Mihai Adrian Ionescu, Arnaud Magrez, Andreas Schueler, Igor Stolichnov, Anna Krammer, Teodor Rosca, Emanuele Andrea Casu, Chen Yan, Nicolò Oliva

Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of mate ...

A Roadmap for the Development of Precision Medicine

Marie-Valentine Renée Agnès Florin, Gérard Escher

The purpose of the roadmap proposed by IRGC is to recommend a structured process that organisations can follow in their transition towards the development of precision medicine. The process is adaptable, and each organisation should further develop it to a ...

Charge-Stripe Order and Superconductivity in Ir1−xPtxTe2

László Forró, Henrik Moodysson Rønnow, Yixing Chen, Johan Juul Chang, Lin Yang, Andrea Pisoni, Edoardo Martino, Péter Krisztián Matus

A combined resistivity and hard x-ray diffraction study of superconductivity and charge ordering in Ir Ir1−xPtxTe2, as a function of Pt substitution and externally applied hydrostatic pressure, is presented. Experiments are focused on samples near the crit ...

Raman Characterization of the Charge Density Wave Phase of 1T-TiSe2: From Bulk to Atomically Thin Layers

Klaus Kern, Marko Burghard, Alexander Ronald Hoyer

Raman scattering is a powerful tool for investigating the vibrational properties of two-dimensional materials. Unlike the 2H phase of many transition metal dichalcogenides, the 1T phase of TiSe2 features a Raman-active shearing and breathing mode, both of ...
