IIT Guwahati researchers have used the contrasting water wetting behaviour for anti-counterfeiting measures. Unlike the rest of the surface, micropatterns produced through molecular printing are highly hydrophilic in nature and…
Researchers at IIT Hyderabad have developed a cheap waterproofing material by coating fly ash, a waste by-product from coal-based thermal power plants, with stearic acid. The surface can be made…
IIT Guwahati researchers have used extremely water-repelling cotton for sustained drug release lasting as long as 110 days. In moderately water-repelling cotton, the drug is released over 50 days. Two…
Researchers at IIT Guwahati have chemically modified the chitosan to make it selectively remove either oil or water phase from an oil-water mixture. In a first, they made it possible…
IIT Guwahati researchers have synthesised an extremely oil-repelling (super oleophobic) membrane using an aloe vera gel-based coating modified with some molecules. This is the first time a naturally occurring material…
IIT Guwahati researchers have developed a superhydrophobic coating that can make the surface behave like a lotus leaf where water droplets roll off easily or a rose petal where the droplets stick…
Using superhydrophobic cotton Dr. Uttam Manna and his team were able to remove 95% of oil-spills, both light and heavy oils. The efficiency of absorption was above 2,000 weight percentage for both…
The superhydrophobic coating exhibits a water contact angle of more than 160 degrees. It has high mechanical durability and chemical stability, and can be coated or spray painted on any surface including…
