research papersHigh-resolution SAXS Setup with Tuneable Resolution in Direct and Reciprocal Space: a New Tool to Study Ordered Nanostructures
High-resolution small-angle X-ray scattering setup based on refractive optics and a variable sample position allows one to achieve tuneable resolution in the direct and reciprocal space. This setup is designed for the study of structural ordering on nano- and micro- scales simultaneously.
books receivedresearch papersUnravelling the strain relaxation processes in silicon nanowires arrays by X-ray diffraction Unravelling the strain relaxation processes in silicon nanowires arrays by X-ray diffraction Unravelling the strain relaxation processes in silicon nanowires arrays by X-ray diffraction
A major problem in characterizing the strain in non-planar structures is to resolve in a standard framework the interplay between the different contributions. In this article, we report an efficient, non-destructive X-ray laboratory formalism that allows a good control of the local examination, providing the strain mapping along the nanowires' length and a quantitative description of the energy transfer inside of the nanowires array, as well as an estimation of the emerged structural defect densities.
research papersDevelopment of spin-contrast-variation neutron reflectometry for the structural analysis of multilayer films
Reflectivity curves of the polarized neutrons remarkably vary as a function of proton polarization of film samples. We demonstrated that detailed structural information of each surface and interface of multilayer film samples can be obtained from these proton-polarization-dependent multiple reflectivity curves.
research papersAlignment of sample position and rotation during in situ synchrotron X-ray micro-diffraction experiments using a Laue cross-correlation approach
A method is described for maintaining sample alignment to a high accuracy during in situ X-ray synchrotron investigations involving 3D mapping of crystal orientations, and application of the method to in situ deformation of samples of fine grain-size aluminium is described.
research papers3D printed droplet generation devices for serial femtosecond crystallography enabled by surface coating
This work has developed, characterized and tested coating procedures for 3D printed droplet generators and also demonstrates sample injection in serial femtosecond crystallography with X-ray free-electron lasers to reduce the vast amount of sample wasted in these crystallography applications.
cryocrystallography papersresearch papersSingle-crystal time-of-flight neutron Laue methods: application to manganese catalase from Thermus thermophilus HB27
Time-of-flight neutron diffraction of a manganese catalase cubic crystal with a = 133 Å was successfully performed using the IBARAKI biological crystal diffractometer.
research papersEffects of annealing parameters on residual stress and piezoelectric performance of ZnO thin films studied by X-ray diffraction and atomic force microscopy
The residual stress and piezoelectric performance of ZnO thin films under different annealing parameters are investigated. The amplitudes of the sample vibrations at different frequencies are measured by a pressure electron microscope.
research papersRecent developments in the Inorganic Crystal Structure Database: theoretical crystal structure data and related features
The article discusses how theoretical crystal data are supplementing experimental data for simulation and prediction of structures of inorganic solids in the Inorganic Crystal Structure Database.
research papersShock-wave-induced nucleation leading to crystallization in water
Shock-wave-induced crystallization in water samples is reported and the mechanism is discussed. The technique provides an alternative method of understanding the crystallization behaviours of different liquids and solid materials, and it can be used as a water purification method.
research papersresearch papersCrystal structure of Mo-substituted lanthanum tungstate La5.4W1−yMoyO12−δ (0 ≤ y ≤ 0.2) studied by X-ray and neutron diffraction
This work describes in detail the crystal structure determination of Mo-substituted lanthanum tungstates through neutron diffraction and high-resolution X-ray diffraction as a function of temperature between T = 10 K and T = 298 K. Combined X-ray and neutron-diffraction refinements and electron-probe micro-analysis were employed to locate Mo atoms in the crystal structure of La5.4W1−yMoyO12−δ (0 ≤ y ≤ 0.2).
research papersCorrelative vibrational spectroscopy and 2D X-ray diffraction to probe the mineralization of bone in phosphate-deficient mice
2D X-ray diffraction and vibrational spectroscopy are used to follow changes in bone remodelling due to different health conditions (pregnancy, lactation) and bone pathologies (phosphate deficiency) in mice.
