IIT Madras team produces white light using pomegranate, turmeric extract

Dr. Vikram Singh, former research scholar in the Department of Chemistry, IIT Madras won the BIRAC Gandhian Young Technological Innovation (GYTI) Award 2017 for his work on producing white light emission using natural extracts. Dr. Singh and Prof. Ashok Mishra from the Department of Chemistry, IIT Madras used a mixture of two natural extracts —... Continue Reading →

IGCAR work may allow doctors to ‘see’ a fever

Visual, non-invasive monitoring of body temperature of patients in hospitals without using a thermometer may become a reality thanks to the work carried out by a team of scientists led by Dr. John Philip, Head of the SMART section at the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam near Chennai. The concept is based... Continue Reading →

IIT Bombay uses mango leaves to make fluorescent graphene quantum dots

Using mango leaves to synthesise fluorescent graphene quantum dots (nanocrystals of semiconductor material), researchers from the Indian Institute of Technology (IIT) Bombay have been able to produce cheap probes for bioimaging and for intracellular temperature sensing. Unlike the currently used dyes, quantum dots synthesised from mango leaves are biocompatible, have excellent photostability and show no... Continue Reading →

IIT Madras researchers prove the superiority of arsenic water filter which got $18 million funding

An exhaustive research carried out by a team of researchers led by Prof. T. Pradeep from the Department of Chemistry at the Indian Institute of Technology (IIT) Madras, spread over four years has put to rest the scepticism about the merits of the arsenic water filter developed by them. The water filter has been in... Continue Reading →

Chennai researchers turn leather waste into electrode-grade carbon

Researchers at the Vellore Institute of Technology (VIT) University, Chennai have successfully converted leather solid waste (wet blue leather splits) containing chromium (III) into porous carbon matrix for use as electrodes in supercapacitors using a simple, sequential, two-step process. This approach not only yielded “excellent porous electrode material for supercapacitors”, but also effectively addressed the... Continue Reading →

IIT Madras researchers with a Midas touch, on a nanoscale

In a breakthrough, a team of researchers from the Indian Institute of Technology (IIT) Madras has successfully transformed nanoscale pieces of silver to gold and gold to silver by replacing their atoms one at a time. The shape and structure of these materials before and after transformation are identical, although they are completely different chemically.... Continue Reading →

IISER Kolkata makes targeted delivery of cancer drug possible

Targeted delivery of anticancer drugs exclusively to cancer cells and controlled release of the drugs in a sustained manner inside cancer cells has been achieved by a group of researchers from the Indian Institute of Science Education and Research (IISER) Kolkata. Porous carbon nanospheres about 150 nm in diameter and packed with drugs inside the... Continue Reading →

BHU researchers use laser to remove blood clots

It is now possible to remove blood clots in a less risky way, thanks to research carried out by scientists at the Institute of Medical Sciences, Banaras Hindu University, Varanasi. A team led by Prof. Debabrata Dash from the Department of Biochemistry  has for the first time used photothermal therapy using near-infrared (NIR) laser and... Continue Reading →

Chennai researchers’ simple approach to produce graphene nanosheets

By using a simple, inexpensive, quick process researchers from the University of Madras have been able to produce a monolayer or a few layers thick graphene nanosheets from graphite material without using any strong oxidising or reducing agents. The results were published in the journal Materials Letters. Among several techniques adopted to synthesize graphene from... Continue Reading →
