Atenolol characterization in solid formulations available in Brazilian market
(2013)
Atenolol is the most used drug in Brazil to hypertension treatment. Two crystal structures are known for this molecule: a racemic form (R,S)-atenolol and a pure form S-atenolol. The racemic form is found in commercial ...
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 ...
Rigid and semi rigid polyurethane resins: a structural investigation using DMA, SAXS and Le Bail method
(Elsevier BVAmsterdam, 2014-10)
Two different types of polyurethane (PU) resins were synthesized with pre-polymer/polyol (-NCO/-OH) mass proportions of 1:1 (Rigid PU) and 1:1.5 (Semi rigid PU). Based on the results from Dynamic Mechanical Analysis (DMA), ...
X-ray powder diffraction analysis of a silver(I)-aspartame complex
(J C P D S-int Centre Diffraction Data, 2006-12-01)
Synchrotron X-ray powder diffraction (XRPD) data were collected for the silver(I)-aspartame complex [Ag(C14H17N2O5)]center dot 1/2 H2O. The complex was obtained from a stoichiometric mixture of aspartame (3-amino-N-(alph ...
Structural and morphological characterization of poly(o-ethoxyaniline) emeraldine-salt form using FTIR, XRD, LeBail method and SEM
(Elsevier BVAmsterdam, 2014-08)
The introduction of polar functional and alkyl groups into the main chain of Polyaniline (PANI) is a mechanism to obtain soluble polymers in a wider variety of organic solvents. Poly(o-ethoxyaniline) (POEA) is a derivative ...
Nanostructured polyaniline emeraldine-base form (EB-PANI): a structural investigation for different neutralization times
(Elsevier BVAmsterdam, 2014-09)
Polyaniline Emeraldine-base form (EB-PANI) was chemically obtained through the neutralization of Polyaniline Emeraldine-salt form (ES-PANI) using NaOH 0.5 M at 3, 24 and 48 h of neutralization. X-ray Diffraction (XRD), Le ...
Synthesis, DFT calculations of structure, vibrational and thermal decomposition studies of the metal complex Pb[Mn(C3H2O4)2(H2O)2]
(Elsevier, 2015-04-15)
The metallo-organic complex Pb[Mn(C3H2O4)2(H2O)2] was synthesized and characterized by IR and Raman spectroscopy and powder X-ray diffraction methods. The cell parameters for the complex were determined from powder X-ray ...
Production and quantification of high-purity mullite at 1600°C from kaolinitic clay and calcined alumina
(Springer, 2015-11)
A study is performed to determine the reaction time which is required at 1600°C to obtain mullite from clay with a high content of kaolinite (clay from the La Rioja Province of Argentina) and from a stoichiometric mixture ...
