Strengthening due to Cr-rich precipitates in Fe–Cr alloys: Effect of temperature and precipitate composition

Molecular dynamics (MD) simulations were carried out to study the interaction between nanometric Cr precipitates and a 1/2 < 111 >>{110} edge dislocation (ED) in pure Fe and Fe-9 at. % Cr (Fe-9Cr) random alloy. The aim of this work is to estimate the vari ...

Super-resolved position and orientation estimation of fluorescent dipoles using 3-D steerable filters

Theo Lasser, Iwan Märki, François Aguet, Stefan Geissbühler

The diffraction patterns of fixed fluorophores are characteristic of the orientation of the molecules' underlying dipole. Fluorescence localization microscopy techniques such as PALM and STORM achieve super-resolution by sequentially imaging sparse subsets ...

Control of polarization and dipole moment in low-dimensional semiconductor nanostructures

Philipp Ridha

We demonstrate the control of polarization and dipole moment in semiconductor nanostructures, through nanoscale engineering of shape and composition. Rodlike nanostructures, elongated along the growth direction, are obtained by molecular beam epitaxial gro ...

Super-resolution orientation estimation and localization of fluorescent dipoles using 3-D steerable filters

Michaël Unser, Theo Lasser, Iwan Märki, François Aguet, Stefan Geissbühler

Fluorophores that are fixed during image acquisition produce a diffraction pattern that is characteristic of the orientation of the fluorophore’s underlying dipole. Fluorescence localization microscopy techniques such as PALM and STORM achieve super-resolu ...

Dipole Moment of Water in Highly Vibrationally Excited States: Analysis of Photofragment Quantum-Beat Spectroscopy Measurements Using a Local-Mode Hamiltonian

Andrea Callegari, Patrice Theulé

We present here the analysis of experimental Stark effect measurements made using photofragment quantum beat spectroscopy on the 14,0->, 15,0->, 18,0+> and 14,0-> 12 > vibrational states of H2O [Callegari, A.; et al. Science 2002, 297, 993.]. To link the m ...

"Bust my buffers" - neutrons disentangle the quantum nature of matter

Henrik Moodysson Rønnow

“Because that is the way it is” I finally answered to our son’s favorite word “Why?”. He had discovered – like most kids his age – that his wooden train with magnetic buffers would pull one end of the wagon, but repel the other end. His first “why” was eas ...

A model for the multi-exponential excited-state decay of CdSe nanocrystals

Majed Chergui, Frank van Mourik, Awos Al Salman

We report on photoluminescence decay measurements of CdSe nanoparticles over several decades of intensities and times, and as a function of size and temp. A model is proposed for the multi-exponential decay kinetics, and their temp. dependence, in which a ...

Field-dependent dielectric and magnetic properties in multiferroic CdCr2S4

Helmuth Berger

Based on the results of field-dependent dielectric and magnetic measurements, we observe several interesting behaviors and phase transitions in this geometrically frustrated spinel system CdCr2S4. (1) A glassy dipolar state occurs near T-C similar to 85 K, ...

Channel and wedge plasmon modes of metallic V-grooves with finite metal thickness

Olivier Martin

We investigate numerically the effect of a finite metal film thickness on the propagation characteristics of the channel plasmon polariton (CPP) and wedge plasmon polariton (WPP) modes, both in a symmetric and asymmetric environment. We observe that decrea ...
