3D Printing Neutron Detectors using Scintillating BN/ZnS Resin [PDF]
, 2020 In this paper we demonstrate that it is possible to produce low cost neutron-sensitive detectors using stereo-lithography additive manufacturing. A curable scintillating resin is made by mixing BN:ZnS with a commercially available UV resin. This resin is used to print several small area neutron detectors made of arrays of BN:ZnS cones that can be ...

The application of Nano-silica gel in sealing well micro-annuli and cement channeling [PDF]
arXiv, 2023 The possibility for hydrocarbon fluids to migrate through debonded micro-annuli wells is a major concern in the petroleum industry. With effective permeability of 0.1-1.0 mD, the existence of channels in a cement annulus with apertures of 10-300 micrometer constitutes a major threat. Squeeze cement is typically difficult to repair channels-leakage with

A note on cement in asteroids [PDF]
Icarus 275, 249 (2016), 2016 Cement mineral tobermorite was formed in hydrothermal experiments on alternation of calcium-aluminum-rich inclusions (CAIs) in carbonaceous chondrite meteorites. Unidentified bands at 14 microns were measured for CAIs and the matrix of the Allende meteorite sample, as well as for Hektor and Agamemnon asteroids.
