Operando Neutron Imaging.

CHIMIA
In the past, neutron imaging has been the little brother of advanced neutron spectroscopy techniques due to its apparent simplicity. However, this simplicity allows the studying of complex chemical and electrochemical processes and related devices even ...

Tailored deformation behavior of 304L stainless steel through control of the crystallographic texture with laser-powder bed fusion

Materials & Design, 2022
Laser-powder bed fusion (L-PBF) has gained significant research interest, not only for its profound advantage of producing near-net shape complex geometries of metallic parts, but also for the possibility of producing tailored microstructures.

Fast Neutron Imaging with Semiconductor Nanocrystal Scintillators.

ACS Nano, 2020
Fast neutrons offer high penetration capabilities for both light and dense materials due to their comparatively low interaction cross sections, making them ideal for imaging of large-scale objects such as large fossils or as-built plane turbines, where X-

Neutron imaging for geomechanics: A review

, 2020
During the last few decades, a number of advanced experimental techniques have provided an unprecedented insight into the behaviour of geomaterials. A notable example are the so-called full-field techniques such as x-ray and neutron imaging, which allow ...

Recent developments in neutron imaging with applications for porous media research [PDF]

Solid Earth, 2016
Computed tomography has become a routine method for probing processes in porous media, and the use of neutron imaging is especially suited to the study of the dynamics of hydrogenous fluids, and of fluids in a high-density matrix.
