Structural characterization of chloride salt of conducting polyaniline obtained by XRD, SAXD, SAXS and SEM
(Elsevier BVAmsterdam, 2013-03)
Emeraldine-salt polyaniline form (ES-PANI) was chemically synthesized using hydrochloric acid at time synthesis ranging from 0.5 to 48 h and characterized by X-ray diffraction (XRD), LeBail fit, Small-angle X-ray diffraction ...
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 ...
