Shear effects on expanded graphite under uniaxial pressure: An in situ small angle neutron scattering study

International audienceIn a previous work [1] we elucidated the in situ evolution of the porosity of out-of-plane com- pressed flexible graphite under uniaxial pressure up to 1000 bar using small-angle neutron scattering (SANS) technique. In order to understand the influence of shear effect on the properties of flexible graphite we study, in the present paper, the in situ behaviour of in-plane compressed flexible graphite under a uniaxial pressure. The sample had a pleated layered structure in which anisotropic SANS patterns revealed a distribution of differently oriented ellipsoid pores. Uniaxial compression generates important shear effects in this kind of sample.We have determined the evolution of the system fractal dimension, pore size distribu- tion and apparent specific surface area with applied pressure which together allow us to describe the meso and macro pore structure evolution. Under pressure, the irreversible col- lapse and splitting of larger pores into smaller size ones which is characteristic of out-of- plane uniaxial compression [1], is accompanied, in the presence of shear stress compo- nents, by an in-plane slipping mechanism giving rise to cracks and consequently to inter- face formation

A Multitechnique Study of Fluorinated Nanodiamonds for Low-Energy Neutron Physics Applications

International audienceData of quasi-specular reflection of cold neutrons, prompt-γ neutron analysis, X-ray Raman scattering (XRS) and neutron Pair distribution function (PDF) analysis with powder of detonation nanodiamonds are analyzed to collect their structural properties and chemical composition. Both as-synthesized and purified were studied using fluorination samples. Removal of both sp 2 amorphous carbon shell and hydrogen atoms is evidenced respectively by the change of neutron-nuclei optical potentials of nanoparticles and the increase of their neutron reflectivity. Moreover, sp 3 diamond cores of nanoparticles stay intact during the fluorination as revealed by similar scattering patterns, PDF and XRS data. Quasi-specular reflection, PDF and XRS data are complementary for the study of nanomaterials and in good agreement with conventional characterization techniques (infrared spectroscopy and solid-state NMR)
