Validation of finite-element simulations with synchrotron radiography – A descriptive study of micromechanics in two-piece dental implants

open access: yesHeliyon, 2018
State-of-the art, two-piece dental implants made from titanium alloys exhibit a complex micromechanical behavior under dynamical load. Its understanding, especially the formation of microgaps, is of crucial importance in order to predict and improve the ...

X-ray microscopy of the breast

open access: yesThe British Journal of Radiology, 1988
Contact X-ray microscopy complements the radiological examination of the breast, including specimen radiography. The technique has been available for many years but has been little used in the study of breast tissue (Leborgne et al, 1957; Barth, 1979; Davies, 1983).

Large-scale physically accurate modelling of real proton exchange membrane fuel cell with deep learning

open access: yesNature Communications, 2023
Accurate liquid water modelling is challenging. Here the authors use X-ray micro-computed tomography, deep learned super-resolution, multi-label segmentation, and direct multiphase simulation to simulate fuel cell and guide fuel cell design.

Laboratory cryo x-ray microscopy for 3D cell imaging

open access: yesScientific Reports, 2017
Water-window x-ray microscopy allows two- and three-dimensional (2D and 3D) imaging of intact unstained cells in their cryofixed near-native state with unique contrast and high resolution. Present operational biological water-window microscopes are based

Hard X-ray nanoprobe scanner

open access: yesIUCrJ, 2021
X-ray scientists are continually striving to improve the quality of X-ray microscopy, due to the fact that the information obtained from X-ray microscopy of materials can be complementary to that obtained from optical and electron microscopes.

Dark-field X-ray microscopy for multiscale structural characterization

open access: yesNature Communications, 2015
Many physical and mechanical properties of crystalline materials depend strongly on their internal structure, which is typically organized into grains and domains on several length scales.

Influence of microfluidic shear on keratin networks in living cells

open access: yesNew Journal of Physics, 2013
Intermediate filaments play a key role in cell mechanics, providing cells with compliance to small deformations and reinforcing them when large forces are applied.

Correlative microscopy approach for biology using X-ray holography, X-ray scanning diffraction and STED microscopy

open access: yesNature Communications, 2018
X-ray techniques benefit from correlative imaging approaches, but combination with super-resolution microscopy has not been explored. Here the authors image the cardiomyocyte cytoskeleton by combining holographic X-ray imaging, X-ray scanning diffraction

Metrology of a Focusing Capillary Using Optical Ptychography

open access: yesSensors, 2020
The focusing property of an ellipsoidal monocapillary has been characterized using the ptychography method with a 405 nm laser beam. The recovered wavefront gives a 12.5×10.4μm2 focus.
