Abstract Autonomous experimentation (AE) is an emerging paradigm that seeks to automate the entire workflow of an experiment, including—crucially—the decision-making step. Beyond mere automation and efficiency, AE aims to liberate scientists to tackle more challenging and complex problems.

Mechanism of Sodium Storage in Hard Carbon: An X‐Ray Scattering Analysis
Advanced Energy Materials, 2019Hard carbon is a standard anode material for Na‐ion batteries. However, its low crystallinity and diverse microstructures make obtaining a full understanding of the sodium storage mechanism challenging. Here, the results of a systematic ex situ small and

Magnetic x-ray Compton scattering
Physical Review B, 1996A theory of magnetic Compton scattering is formulated. The cross section is found to be insensitive to orbital effects, in agreement with recent experiments on transition-metal and rare-earth ferromagnets. When the transferred energy is sufficiently small to generate substantial corrections to the impulse approximation, the sensitivity to orbital ...

X-ray scattering methods with polymers generally require a source of monochromated radiation, which for convenience is usually Cu-Kα with a wavelength of 0.15418 nm, giving optimum compromise between resolution and scattered intensity. Scattering studies can give at wide angles (WAXS) information about the crystal structure, the crystallinity and the ...

THE large lattice spacings occurring in such organic matter as fibres or crystalline viruses give rise to X-ray diffraction patterns with Bragg angles of minutes of arc rather than of degrees. The neighbourhood of the direct beam is, however, for a variety of reasons, easily obscured by scattered radiation and insufficient collimation, so that special ...

X-Ray Resonance Exchange Scattering
Physical Review Letters, 1988Large resonant magnetization-sensitive x-ray scattering is predicted to occur in the vicinity of the L/sub II/, L/sub III/, and M/sub II/--M/sub V/ absorption edges in the rare-earth and actinide elements, and at the K and L edges in the transition elements.

X-Ray Resonant Inelastic Scattering
1995With the advent of synchrotron radiation sources, characterised by high fluxes, tunability and polarisation control, the inelastic scattering of x rays has become a powerful probe of ground-state properties and elementary excitations in solids.

New developments in x‐ray scattering are resulting from the use of synchrotron radiation sources, allowing study of anomalous scattering regimes with high energy resolution and polarized light. S matrix calculations of elastic scattering are in good agreement away from edges, while dispersion relations can be used to predict edge region scattering if a

Nondestructive Testing and Evaluation, 2005
This paper discusses issues related to the development of reconstructed tomography based on scattered X-ray radiation. For most X-ray tomography, based on collimated initial and scattered radiation, the distribution of the object density (linear scattering coefficient) is reconstructed by the number of counted photons scattered in the reconstructed ...
