Silver atoms of nanoparticles are mobile, IIT Madras team finds

IIT Madras researchers have discovered that atoms of nanoparticles made of two silver isotopes having just 25 atoms each rapidly exchanged their positions when the isotopes are mixed in solution. New particles composed of nearly 50% mixture of both isotopes were formed. This is akin to the exchange of hydrogen and deuterium atoms when normal … Continue reading Silver atoms of nanoparticles are mobile, IIT Madras team finds

Retraction saga: IIT Dhanbad faculty learnt to reuse published images during their doctoral programme

Rashmi Madhuri and Prashant Sharma of IIT Dhanbad have 15 and 19 papers respectively listed on Pubpeer website. These papers have been published while they were doing their doctoral programme at different institutes. Like their two dozen retracted papers, these papers too have serious issues with published images being reused to represent different samples or … Continue reading Retraction saga: IIT Dhanbad faculty learnt to reuse published images during their doctoral programme

Two dozen papers by IIT Dhanbad faculty retracted so far, many more still under a cloud

Rashmi Madhuri and Prashant Sharma, Assistant Professors at IIT Dhanbad, have so far collected over 24 retractions. And many more papers with similar problem of image duplication have been listed on Pubpeer website. The investigation by the institute is still under way and will probably be completed by March-April 2019. Indian Institute of Technology (Indian … Continue reading Two dozen papers by IIT Dhanbad faculty retracted so far, many more still under a cloud

Podcast: Increasing Li-ion battery’s capacity, charging speed

Kingshuk Roy of IISER Pune explains how the novel anode made of silicon-phosphorene mixture for use in Li-ion batteries has five times more capacity than carbon-based electrodes and can be fully charged in about 15 minutes. The researchers used just 8% of phosphorene to dramatically improve the stability of silicon electrode. The electrode showed no … Continue reading Podcast: Increasing Li-ion battery’s capacity, charging speed

IISER Pune’s novel anode increases Li-ion capacity, quickens battery charging

IISER Pune researchers have fabricated a novel anode made of silicon-phosphorene mixture for use in Li-ion batteries. The anode has five times more capacity than carbon-based electrodes and can be fully charged in about 15 minutes. The electrode showed no discernible cracks even after 250 cycles of charging and discharging. A novel anode developed by … Continue reading IISER Pune’s novel anode increases Li-ion capacity, quickens battery charging

Podcast: Removing oil from water using aloe vera

Uttam Manna of IIT Guwahati explains how his team synthesised an extremely oil-repelling (super oleophobic) membrane using an aloe vera gel-based coating modified with some molecules to remove oil from water. The membrane could be reused at least 25 times to separate light and heavy oil from water with the efficiency of separation remaining above … Continue reading Podcast: Removing oil from water using aloe vera

IIT Guwahati uses aloe vera to remove oil from water

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 has been used for the said purpose. The membrane could be reused at least 25 times to separate light and heavy oil from water with … Continue reading IIT Guwahati uses aloe vera to remove oil from water

IISc team uses iodine to increase cellular uptake of fluorescent probe

IISc researchers have drastically improved (up to 98%) the cellular uptake of fluorescent probe naphthalimide by substituting two of its hydrogen atoms with iodine. The iodine atom forms a halogen bond with the MCT8 receptor that ferries the molecule across the cell membrane. The probe molecule with iodine will also help in studying the uptake of thyroid hormone. By … Continue reading IISc team uses iodine to increase cellular uptake of fluorescent probe

IIT Madras’ novel technique helps detect paraffin oil contamination in coconut oil

IIT Madras researchers have used a novel approach to analyse various saturated and unsaturated hydrocarbons directly from solutions. Using the novel technique, the researchers could detect paraffin oil in coconut oil. The extent of paraffin oil contamination in coconut oil bought from the local market was as high as 10%. Using a novel approach, researchers at … Continue reading IIT Madras’ novel technique helps detect paraffin oil contamination in coconut oil

IIT Guwahati develops superhydrophobic coating that mimics lotus leaves, rose petals

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 till the angle of tilt goes beyond 20 degrees. The coating, which can be spray-painted on diverse surfaces of any geometry and size, has several … Continue reading IIT Guwahati develops superhydrophobic coating that mimics lotus leaves, rose petals
