A Cylindrical Cell for Operando Neutron Diffraction of Li-Ion Battery Electrode Materials

Frontiers in Energy Research, 2018
Neutron diffraction is a powerful technique to localize and quantify lithium in battery electrode materials. However, obtaining high-quality operando neutron diffraction data is challenging because it requires achieving good electrochemical performance ...

Neutron reflectivity and grazing angle diffraction

Journal of Research of the National Institute of Standards and Technology, 1993
Over the last 10 years, neutron reflectivity has emerged as a powerful technique for the investigation of surface and interfacial phenomena in many different fields. In this paper, a short review of some of the work on neutron reflectivity and grazing-angle diffraction as well as a description of the current and planned neutron rcflectometers at NIST ...

Neutron Diffraction

, 2017
Neutron diffraction as an analytical tool in solid-state chemistry is briefly presented. We start by recalling a few characteristic properties of the neutron that make thermal neutrons a unique structural probe in solid-state science. The generation of neutrons, some fundamentals of neutron diffraction, concepts and components of instrumentation for ...

A neutron laue diffraction study of endothiapepsin: Implications for the aspartic proteinase mechanism [PDF]

, 2001
Current proposals for the catalytic mechanism of aspartic proteinases are largely based on X-ray structures of bound oligopeptide inhibitors possessing nonhydrolyzable analogues of the scissile peptide bond.

Advances in martensitic transformations in Cu-based shape memory alloys achieved by in situ neutron and synchrotron X-ray diffraction methods [PDF]

, 2012
This article deals with the application of several X-ray and neutron diffraction methods to investigate the mechanics of a stress induced martensitic transformation in Cu-based shape memory alloy polycrystals. It puts experimental results obtained by two

A Mössbauer spectroscopy and neutron diffraction study of magnetostrictive, melt-spun Fe-Ga alloy ribbons [PDF]

, 2012
Ribbons of Fe100−xGax (x=15, 17.5, 19.5 and 22.5) were prepared by rapid solidification from the melt. 57Fe Mössbauer spectroscopy and high resolution neutron diffraction have revealed that Fe1−xGax alloys with x=15 and 17.5 have the disordered bcc (A2 ...

Study of Constitutive Behavior of Ferroelectrics via Self-Consistent Modeling and Neutron Diffraction [PDF]

, 2007
The central goal of this study is to develop a reliable self-consistent model to describe the constitutive behavior of polycrystalline ferroelectrics and to predict their lattice strain and texture evolution. Starting with the model developed by Huber et

Measurement of strain evolution in overloaded roller bearings using time-of-flight neutron diffraction

Materials & Design, 2020
Neutron diffraction is an established method for non-destructively characterising residual stress or observing in situ strain during external stimuli. Neutron based stroboscopic techniques have previously been introduced for measuring strains undergoing ...

Neutron diffraction studies of magnetostrictive Fe–Ga alloy ribbons [PDF]

, 2008
Melt-spun Fe–Ga ribbons were prepared and some ribbons were annealed at 1000 °C for 1 h then slowly cooled to room temperature. X-ray diffraction patterns revealed no evidence of texture and only bcc phase in the as-quenched ribbons.
