In situ X-ray diffraction studies on the piezoelectric response of PZT thin films
(Elsevier B.V., 2016-03-31)
Piezoelectric properties of randomly oriented self-polarized PbZr0.50Ti0.50O3 (PZT) thin films were investigated using in situ synchrotron X-ray diffraction. Possibilities for investigating the piezoelectric effect using ...
Distance limits on the bright X-ray emission toward the Galactic center: Evidence for a very hot interstellar medium in the Galactic X-ray bulge
(UNIV CHICAGO PRESS, 2000-12-10)
Observations of the diffuse X-ray background at energies similar to3/4 and 1.5 keV show a large region of enhanced emission around the Galactic center. The origin of this X-ray enhancement is not known, but the best ...
Exploratory X-ray monitoring of luminous radio-quiet quasars at high redshift: initial results
(The American Astronomical Society, 2014)
We present initial results from an exploratory X-ray monitoring project of two groups of comparably luminous
radio-quiet quasars (RQQs). The first consists of four sources at 4.10 z 4.35, monitored by Chandra, and ...

Bounds on direct couplings of superheavy metastable particles to the inflaton field from ultra high energy cosmic ray events
(World Scientific Publ Co Pte Ltd, 2002-10-30)
Top-down models for the origin of ultra high energy cosmic rays (UHECR's) propose that these events are the decay products of relic superheavy metastable particles, usually called X particles. These particles can be produced ...

Application of the X-ray densitometry in the evaluation of the quality and mechanical properties of biomass pellets
(Elsevier, 2015-04)
The use of the X-ray technique and the X-ray densitometry to determine pellet particle distribution and to understand the biomass compaction and its effects in pellet properties has been limited. The present work evaluates ...
Correlated X-ray/optical variability in the quasar MR2251-178
(2008)
Emission from Active Galactic Nuclei is known to vary strongly over time over a wide energy band, but the origin of the variability and especially of the inter-band correlations is still not well established. Here we present ...
