A Dilatometric Study of Graphite Electrodes during Cycling with X-ray Computed Tomography

Journal of the Electrochemical Society, 2020
Graphite is the most commonly used anode material in commercial lithium-ion batteries (LiBs). Understanding the mechanisms driving the dimensional changes of graphite can pave the way to methods for inhibiting degradation pathways and possibly predict ...

In situ 3D characterization of fatigue cracks displacement fields [PDF]

Fracture and Structural Integrity, 2013
The three dimensional growth of fatigue cracks in samples of nodular graphite cast iron is characterized using laboratory X-ray computed tomography. The cracks grow from laser machined artificial defects, their development is monitored in situ using ...

Effects of X-Ray Dose On Rhizosphere Studies Using X-Ray Computed Tomography.

PLoS ONE, 2013
X-ray Computed Tomography (CT) is a non-destructive imaging technique originally designed for diagnostic medicine, which was adopted for rhizosphere and soil science applications in the early 1980s.

X-Ray Fluorescence Computed Tomography With Polycapillary Focusing

IEEE Access, 2014
Liposomal iodine nanoparticles (LINPs) have a long half-life and provide an excellent intravascular contrast. The nanoparticles can be functionalized as molecular probes for biological targets to facilitate numerous preclinical studies for translation ...

X-Ray Luminescence and X-Ray Fluorescence Computed Tomography: New Molecular Imaging Modalities

IEEE Access, 2014
X-ray luminescence and X-ray fluorescence computed tomography (CT) are two emerging technologies in X-ray imaging that provide functional and molecular imaging capability. Both emission-type tomographic imaging modalities use external X-rays to stimulate

X-ray computed tomography [PDF]

Physics Education, 2001
X-ray computed tomography (CT) is a medical imaging technique that produces images of transaxial planes through the human body. When compared with a conventional radiograph, which is an image of many planes superimposed on each other, a CT image exhibits significantly improved contrast although this is at the expense of reduced spatial resolution. A CT

Multi-Detector CT Findings of Typical and Atypical Appendicitis: A Pictorial Essay

Journal of the Korean Society of Radiology, 2023
Multi-detector CT (MDCT) is a highly accurate diagnostic tool that is commonly used to evaluate appendicitis and its complications. The diagnosis of appendicitis based on MDCT findings can be difficult and challenging when the observed findings are ...

Interlaced X-ray diffraction computed tomography [PDF]

Journal of Applied Crystallography, 2016
An X-ray diffraction computed tomography data-collection strategy that allows, post experiment, a choice between temporal and spatial resolution is reported. This strategy enables time-resolved studies on comparatively short timescales, or alternatively allows for improved spatial resolution if the system under study, or components within it, appear to

A Bismuth Metal-Organic Framework as a Contrast Agent for X-ray Computed Tomography.

ACS Applied Bio Materials, 2019
A new bismuth metal-organic framework (MOF), bismuth-NU-901 (Bi-NU-901), featuring the scu topology and a pore with a diameter of ∼11 Å, was solvothermally synthesized, and its use as an X-ray computed tomography (CT) contrast agent was tested.
