Reactive sputter magnetron reactor for preparation of thin films and simultaneous in situ structural study by X-ray diffraction
(Amer Inst Physics, 2013-01)
The purpose of the designed reactor is (i) to obtain polycrystalline and/or amorphous thin ﬁlms by controlled deposition induced by a reactive sputtering magnetron and (ii) to perform a parallel in situ structural study ...
X-ray powder diffraction analysis of a silver(I) cyclamate complex
(J C P D S-int Centre Diffraction Data, 2007-03-01)
X-ray powder diffraction data collected for the complex silver(I) cyclamate [Ag(C6H12NO3S)] are reported. This material was obtained from a stoichiometric mixture of sodium cyclamate and AgNO3. The analysis of the data ...

Lanthanum cobaltite black pigments with perovskite structure
In this work La1-xCaxCoO3 (x = 0-0.4) pigments were synthesized by the polymeric precursor method with heat treatments at 700, 800 and 900 C for 4 h. The powders were characterized by colorimetry, UV-vis spectroscopy and ...
Films from resistant starch-pectin dispersions intended for colonic drug delivery
Free films were obtained by the solvent casting method from retrograded starch-pectin dispersions at different polymer proportions and concentrations with and without plasticizer. Film forming dispersions were characterized ...

Influence of annealing on X-ray diffraction of natural alexandrite
(J C P D S-int Centre Diffraction Data, 2002-06-01)
In this work we present results of X-ray diffraction using powder method, on natural alexandrite samples from Minas Gerais State (Brazil), as a function of a sequence of annealing. From these measurements we determine ...
