Influence of Mg on the structural and optical properties of LiNbO3 thin films grown by polymeric precursor method
(Trans Tech Publications Ltd, 2005-01-01)
A polymeric precursor solution was used to deposit pure and Mg doped LiNbO3 thin films on sapphire substrates by spin-coating. The effects of magnesium addition on crystallinity, morphology and optical properties of the ...
Aryl Naphthoates: A Conformational Analysis Supported by Single-Crystal X-Ray Diffraction
(Csiro Publishing, 2016-08)
The conformational study by X-ray diffraction of 12 aroyl esters of ortho-acetyl phenols is reported. The data are supported by theoretical calculations and described in terms of co-planarity, intramolecular steric ...
Influence of barium and strontium addition on the ratio c/a of PZT obtained by the polymeric precursor method
Lead zirconate titanate powder, with Zr/Ti ratio of 50/50 was prepared by Pechini method after adding up to 10,0 mol% of Ba +2 and Sr +2 ions. Tetragonal phase is favored by the increase of barium and strontium concentration ...
A powder X-ray diffraction method for detection of polyprenylated benzophenones in plant extracts associated with HPLC for quantitative analysis
(ELSEVIER SCIENCE BV, 2011)
A robust, direct, rapid and non-destructive X-ray diffraction crystallography method to detect the polyprenylated benzophenones 7-epi-clusianone (1) and guttiferone A (2) in extracts from Garcinia brasiliensis is presented. ...
Pearlitic reaction in Cu-10wt%Al alloy with Ag additions
(J C P D S-int Centre Diffraction Data, 2008-06-01)
The pearlitic reaction in Cu-10wt%Al alloy with additions of 4, 6, 8, and 10wt%Ag was studied using scanning electron microscopy, energy dispersive X-ray microanalysis, in situ X-ray diffractometry, and microhardness ...
A NEW STRUCTURAL MODIFICATION OF STANNITE

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 ...
On the determination of stress profiles in expanded austenite by grazing incidence X-ray diffraction and successive layer removal
Surface layers of expanded austenite resulting from nitriding typically exhibit large gradients in residual stress and composition. Evaluation of residual-stress profiles is explored by means of grazing incidence X-ray ...
Growth and capping of InAs/GaAs quantum dots investigated by x-ray Bragg-surface diffraction
(AMER INST PHYSICS, 2009)
An x-ray diffraction method, based on the excitation of a surface diffracted wave, is described to investigate the capping process of InAs/GaAs (001) quantum dots (QDs). It is sensitive to the tiny misorientation of (111) ...
Powder Diffraction of Components Subject to Corrosion in Fuse Cutouts with CeramicInsulation
(Trans Tech Publications Ltd, 2008-01-01)
Aiming identification of the components most affected by corrosion under saline environment conditions, we have carried out X-ray diffraction measurements in ceramic and bond materials, all in the powder form. The ceramic ...
