Spectrophotometric Method for Simultaneous Estimation of Escitalopram Oxalate and Clonazepam in Tablet Dosage Form
A simple, accurate and precise spectrophotometric method has been developed for simultaneous estimation of escitalopram oxalate and clonazepam in combined dosage form. Simultaneous equation method is employed for simultaneous determination of escitalopram oxalate and clonazepam from combined dosage forms. In this method, the absorbance was measured at 238 nm for escitalopram oxalate and 273 nm for clonazepam. Linearity was observed in range of 5-100 ÎŒg/ml and 5-50 ÎŒg/ml for escitalopram and clonazepam respectively. Recovery studies confirmed the accuracy of proposed method and results were validated as per ICH guidelines. The method can be used for routine quality control of pharmaceutical formulation containing escitalopram and clonazepam

Organic-inorganic hybrid sol-gelcoatings for metal corrosion protection: a review of recent progress
This paper is a review of the most recent and relevant achievements (from 2001 to 2013) on the development of organicâinorganic hybrid (OIH) coatings produced by solâgel-derivedmethods to improve resistance to oxidation/corrosion of different metallic substrates and their alloys. This review is focused on the research of OIH coatings based on siloxanes using the solâgel process conducted at an academic level and aims to summarize the materials developed and identify perspectives for further research. The fundamentals of solâgel are described, including OIH classification, the interaction with the substrate, their advantages, and limitations. The main precursors used in the synthesis ofOIHsolâgel coatings for corrosion protection are also discussed, according to the metallic substrate used. Finally, a multilayer system to improve the resistance to corrosion is proposed, based on OIH coatings produced by the solâgel process, and the future research challenges are debated.FundacĂŁo para a CiĂȘncia e Tecnologia (FCT) for the PhD grant SFRH/BD/62601/2009, Centro de QuĂmica [project F-COMP-01-01024-FEDER-022716 (ref.
