Solidity without inhomogeneity: perfectly homogeneous, weakly coupled, UV-complete solids

Solid-like behavior at low energies and long distances is usually associated with the spontaneous breaking of spatial translations at microscopic scales, as in the case of a lattice of atoms. We exhibit three quantum field theories that are renormalizable, ...

Structural and Dynamical Properties of Potassium Dodecahydro-monocarba-closo-dodecaborate: KCB11H12

Mirjana Dimitrievska, Wei Zhou

MCB11H12 (M: Li, Na) dodecahydro-monocarba-closo-dodecaborate salt compounds are known to have stellar superionic Li+ and Na+ conductivities in their high-temperature disordered phases, making them potentially appealing electrolytes in all-solid-state batt ...

Opto-acoustic chemical sensor based on forward stimulated Brillouin scattering in optical fiber

Luc Thévenaz, Desmond Chow Ming Chia

Stimulated Brillouin scattering is well-known for providing distributed measurements in the field of optical fiber sensing. For the conventional backward stimulated Brillouin scattering, the sensing capability is nevertheless limited to temperature and mec ...

Design of Surface-Supported Bio-inspired Networks for CO2 and O2 Activation at Room Temperature

Daniel Eduardo Hurtado Salinas

The structure of a biological system defines its function. Therefore, nature has developed sophisticated systems that catalyze chemical reactions that are vital for life on earth. For instance, the photosynthesis is a biological process that is partially r ...

Two-Dimensional Nanoparticle Supracrystals: A Model System for Two-Dimensional Melting

Francesco Stellacci, Jiwon Kim

In a Langmuir trough, successive compression cycles can drive a two-dimensional (2D) nanoparticle supracrystal (NPSC) closer to its equilibrium structure. Here, we show a series of equilibrated 2D NPSCs consisting of gold NPs of uniform size, varying solel ...

A Simple Liquid-Liquid Biphasic System for Hydrogen Peroxide Generation

Hubert Girault, Gunther Wittstock

Although electron transfer reactions at liquid liquid interfaces have been thoroughly studied in the presence of deliberately added potential determining ions or phase transfer catalysts, little is known about these reactions in the absence of the above sp ...

Hyperbolic spin vortices and textures in exciton-polariton condensates

Benoît Marie Joseph Deveaud, Francesco Manni

From cosmology to the microscopic scales of the quantum world, the study of topological excitations is essential for the understanding of phase conformation and phase transitions. Quantum fluids are convenient systems to investigate topological entities be ...

Probing the Interaction Between a Surfactant-Cobalt(III) Complex and Bovine Serum Albumin

Hubert van den Bergh, Georges Wagnières

The mechanism of binding of the surfactant-cobalt(III) complex, cis-[Co(phen) 2(C 14H 29NH 2)Cl](ClO 4) 2{dot operator}3H 2O (phen = 1,10-phenanthroline, C 14H 29NH 2 = tetradecylamine) with bovine serum albumin (BSA) was investigated by UV-vis absorption, ...

Thermodynamic assessment of the Cu-Ge binary system

Alain Jacot, Christian Leinenbach, Jian Wang, Shan Jin

The Cu-Ge binary system was assessed thermodynamically using the CALPHAD method through Thermocalc (R) software package based on the evaluation of all available experimental data from the published literature. The solution phases, including liquid, fcc, hc ...

Transition from Mn4+ to Mn3+ induced by surface reconstruction at lambda-MnO2(001)

Alfonso Baldereschi, Zeljko Sljivancanin

Structural and electronic properties of the lambda-MnO2(001) surface are investigated applying density functional theory approach. The calculations show that all Mn ions at unreconstructed smooth surface preserve the +4 oxidation state observed in the bulk ...
