Mapping of Chemical Heterogeneity at Surfaces with High-Throughput Wide-Field Second Harmonic Microscopy

Many industrial processes are based on electrochemical reactions using engineered electrocatalysts. However, the current lack of theoretical knowledge obscures efforts to maximize catalysts' efficiency, and the optimization process is mostly empirical. To ...

Transmissivity of rock fractures: Normal loading and shear reactivation

Monia Woehner

Enhanced Geothermal Systems represent a major field of study in the context of renewable energy resources. To create extractable energy from those reservoirs, a high enough fluid flow rate for production needs to be achieved. This fluid flow rate is direct ...

Anisotropic magnetic polymer nanocomposite with self-assembled chains of titania-coated magnetite nanoparticles

Yves Leterrier, Tommaso Nardi

An anisotropic magnetic nanocomposite has been prepared by incorporating magnetite nanoparticles (average size: 19nm) in titania (TiO2) particles with a typical size of about 100nm, which are sub- sequently dispersed in a liquid epoxy monomer cured under a ...

Response to "Critical Assessment of the Evidence for Striped Nanoparticles"

Francesco Stellacci, Quy Ong Khac

Stirling et al., (10.1371/journal.pone.0108482) presented an analysis on some of our publications on the formation of stripe-like domains on mixed-ligand coated gold nanoparticles. The authors shed doubts on some of our results however no valid argument is ...

Silicon micromachined ultrasonic scalpel for the dissection and coagulation of tissue

Nico de Rooij, Danick Briand, Pierre-André Farine, Alexis Boegli, Robert Andrew Lockhart, Christian Robert, Patrick Stadelmann

This work presents a planar, longitudinal mode ultrasonic scalpel microfabricated from monocrystalline silicon wafers. Silicon was selected as the material for the ultrasonic horn due to its high speed of sound and thermal conductivity as well as its low d ...

Scanning tunneling microscopy and small angle neutron scattering study of mixed monolayer protected gold nanoparticles in organic solvents

Francesco Stellacci, Quy Ong Khac, Javier Reguera Gomez, Kellen Michael Harkness, Mauro Moglianetti, Marta Mameli

When a binary mixture of ligand molecules is used to coat gold nanoparticles, stripe-like domains can occur. These nanodomains confer nanoparticles unique structure-dependent properties. The domain structure has been characterized primarily using scanning ...

Medium-range structure of vitreous SiO2 obtained through first-principles investigation of vibrational spectra

Alfredo Pasquarello, Luigi Giacomazzi

Using a density-functional framework, we investigate the vibrational spectra of vitreous SiO2 to determine to what extent these spectra provide information about the medium-range structure of the oxide network. We carry out a comparative study involving th ...

Cristobalite inclusions in the Tatahouine achondrite: Implications for shock conditions

Philippe Gillet

The mineralogy of the Tatahouine diogenite was investigated by optical microscopy, Raman micro-spectrometry, and scanning and transmission electron microscopies. Inclusions of alpha-cristobalite in orthopyroxenes, locally in symplectic association with chr ...

Pressure-Induced Structural Modifications In Mg2Geo4-Olivine - A Raman-Spectroscopic Study

Philippe Gillet

Raman spectra of Mg2GeO4-olivine were obtained from ambient pressure up to 34 GPa at ambient temperature. Under quasi-hydrostatic pressure conditions, the following modifications in the Raman spectra occur as pressure increases: 1) near 11 GPa, two sharp e ...
