Time Resolved Two Dimensional X-Ray Densitometry of a Two Phase Flow Downstream of a Ventilated Cavity [PDF]

open access: yes, 2013
To measure the void fraction distribution in gas-liquid flows, a two-dimensional x-ray densitometry system was developed. This system is capable of acquiring a two-dimensional projection with a 225 cm2 area of measurement through 21 cm of water.

Characterization of defect structures in nanocrystalline materials by X-ray line profile analysis [PDF]

open access: yes, 2007
X-ray line profile analysis is a powerful alternative tool for determining dislocation densities, dislocation type, crystallite and subgrain size and size-distributions, and planar defects, especially the frequency of twin boundaries and stacking faults.

Synchrotron X-ray topographic analysis of the impact of processing steps on the fabrication of AlGaAs/InGaAs p-HEMT's [PDF]

open access: yes, 1996
Synchrotron X-Ray Topography (SXRT) has been uniquely applied to nondestructively reveal and evaluate the damage throughout the depth of the wafer, caused by the deposition of source/gate/drain metallization and of so-called “passivation” dielectric ...

Quantum-Sized Zinc Oxide Nanoparticles Synthesised within Mesoporous Silica (SBA-11) by Humid Thermal Decomposition of Zinc Acetate

open access: yesCrystals, 2020
A modified facile method is presented to synthesise quantum-sized zinc oxide nanoparticles within the pores of a mesoporous silica host (SBA-11). This method eliminates the 3 h alcohol reflux and the basic solution reaction steps of zinc acetate.

Thermal behavior of corn starch granules modified by acid treatment at 30 and 50°C

open access: yesEclética Química, 2018
Unprocessed native starches are structurally too weak and functionally too restricted for application in today’s advanced food technologies. Processing is necessary to engender a range of functionality.

The effect of proton damage on the X-ray spectral response of MOS CCDs for the swift X-ray telescope [PDF]

open access: yes, 2002
The effect of non-ionising energy loss(NIEL) of protons in charge-coupled devices is to displace silicon atoms and any dopant materials present from their lattice positions to form lattice defects which in turn can trap electrons [1].
