Morphological characterization of a polymeric microfiltration membrane by synchrotron radiation computed microtomography [PDF]

open access: yes, 2007
Most commercial polymeric membranes are prepared by phase inversion. The performance of the membranes depends greatly on the morphology of the porous structure formed during the different steps of this process.

In Vivo Time- Resolved Microtomography Reveals the Mechanics of the Blowfly Flight Motor [PDF]

open access: yes, 2014
Dipteran flies are amongst the smallest and most agile of flying animals. Their wings are driven indirectly by large power muscles, which cause cyclical deformations of the thorax that are amplified through the intricate wing hinge.

Effect of Glass Fiber Hybridization on the Behavior Under Impact of Woven Carbon Fiber/Epoxy Laminates [PDF]

open access: yes, 2010
The low-velocity impact behavior was studied in hybrid laminates manufactured by RTM with woven carbon and glass (S2) fabrics. Specimens with different thicknesses and glass fiber content (from 0 to 21 vol.%) were tested with impact energies in the range

Combination of Imaging Infrared Spectroscopy and X-ray Computed Microtomography for the Investigation of Bio-and Physicochemical processes in Structured Soils [PDF]

open access: yes, 2020
Soil is a heterogeneous mixture of various organic and inorganic parent materials. Major soil functions are driven by their quality, quantity and spatial arrangement, resulting in soil structure.

X-ray computed microtomography of Megachirella wachtleri [PDF]

open access: yesScientific Data, 2018
AbstractUnderstanding the origin and early evolution of squamates has been a considerable challenge given the extremely scarce fossil record of early squamates and their poor degree of preservation. In order to overcome those limitations, we conducted high-resolution X-ray computed tomography (CT) studies on the fossil reptile Megachirella wachtleri ...

First diagnosis of septic arthritis in a dinosaur [PDF]

open access: yesRoyal Society Open Science, 2016
Identification and interpretation of pathologies in the fossil record allows for unique insights into the life histories of extinct organisms. However, the rarity of such finds limits not only the sample size for palaeopathologic studies, but also the ...

Investigation of particle breakage under one-dimensional compression of sand using X-ray microtomography

open access: yes, 2020
Particle breakage alters particle-scale properties of granular soils including particle size, shape, and contact conditions, and changes macroscale properties including soil compressibility, shear ...

Identification of ginseng root using quantitative X-ray microtomography

open access: yesJournal of Ginseng Research, 2017
Background: The use of X-ray phase-contrast microtomography for the investigation of Chinese medicinal materials is advantageous for its nondestructive, in situ, and three-dimensional quantitative imaging properties.
