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

open access: yes, 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

DIFFRACTION PATTERNS?

open access: yes, 2013
Feminist analysis of science and technology is in the need of finding, first, innovative epistemic ways to empower those who are dis-empowered by gender hierarchies, racism, classism, homophobia, and other ideological conditions that classify persons in structural hierarchies.

A new heuristic geometrical approach for finding non-coplanar multiple edge diffraction ray paths [PDF]

open access: yes, 2006
Rooftop diffraction can contribute significantly to the propagation path loss in outdoor microcellular environments. For non-coplanar multiple edges, the finding of exact ray paths requires a complex algebraic analysis that is infeasible for rapid ...

Plane wave diffraction by a rational wedge

open access: yes, 1986
In this paper new expressions for the acoustic field produced when a plane wave source of sound is diffracted by a soft, hard or mixed soft/hard wedge whose angle can be expressed as a rational multiple of are given. The solution is expressed in terms of

DiffraGAN: a conditional generative adversarial network for phasing single molecule diffraction data to atomic resolution

open access: yesFrontiers in Molecular Biosciences
IntroductionProteins that adopt multiple conformations pose significant challenges in structural biology research and pharmaceutical development, as structure determination via single particle cryo-electron microscopy (cryo-EM) is often impeded by data ...

Ab initio structure determination from X-ray powder diffraction data

open access: yes, 2015
Many important crystalline solids cannot be prepared in the form of single crystals of sufficient size and quality for single crystal X-ray diffraction studies, and in such cases it is essential that structural information can be extracted from powder ...

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

open access: yes, 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.
