Development of liquid repellent coating on cotton fabric by simple binary silanization with excellent self-cleaning and oil-water separation properties.

This paper aims to develop a facile and single step method for the fabrication of superhydrophobic coating on cotton fabric. The coating has been prepared by using two silane trichloro(octadecyl)silane and (pentaflurophenyl)triethoxy silane by solution immersion technique. The wettability, surface topography and chemical compostion of the cotton fabric before and after treatment were charecterized by contact angle measurement, scanning electron microscope, and energy dispersive X-ray spectrum, respectively.

Fabrication of Mechanically Stable Superhydrophobic Aluminium Surface with Excellent Self-Cleaning and Anti-Fogging Properties.

The development of a self-cleaning and anti-fogging superhydrophobic coating for aluminium surfaces that is durable in aggressive conditions has raised tremendous interest in materials science. In this work, a superhydrophobic Al surface was synthesized by employing chemical etching technique with a mixture of hydrochloric and nitric acids, followed by passivation with lauric acid. The surface morphology analysis revealed the presence of rough microstructures on the coated Al surface.

Safety and efficacy of low molecular weight heparin therapy during pregnancy: three year experience at a tertiary care center.

Purpose: To evaluate safety and efficacy of low molecular weight heparin given for various indications during pregnancy.

Methodology: A detailed retrospective analysis of all the patients who received low molecular weight heparin (LMWH) for various indications over a period of 3 years (2010-2012) at a tertiary care hospital in Northern India was performed.

Results: Fifty-five patients received LMWH over the period of 3 years, for various indications.
