IISc researchers observe superconductivity at ambient temperature, pressure

IISc researchers have for the first time been able to achieve superconductivity at ambient temperature and pressure. The resistance observed is very low (10-4 ohms) but not zero. Though they didn’t observe perfect Meissner effect (where the magnetic fields are completely expelled by the superconducting state), they did observe samples becoming strongly diamagnetic, which is consistent with … Continue reading IISc researchers observe superconductivity at ambient temperature, pressure

UoH team makes harpin biopesticide more potent by increasing its bioavailability

University of Hyderabad researchers encapsulated harpin biopesticide in chitosan nanoparticles and achieved 80-90% reduction in severity of fungal infection in tomato plants. The chitosan nanoparticles containing harpin pass through the cell wall and end up in the chloroplast of tomato plants thereby improving bioavailability. Tomato plants and R. solani fungal infection were only used as a model system. … Continue reading UoH team makes harpin biopesticide more potent by increasing its bioavailability

IIT Hyderabad’s novel composite keeps tomatoes fresh for 30 days

IIT Hyderabad researchers have developed a novel composite using bacterial cellulose impregnated with silver nanoparticles. The food packaging material has antimicrobial activity and allows appropriate exchange of gases and moisture. Tomatoes wrapped using the composite remained fresh without any microbial spoilage even at the end of 30 days. Researchers at Indian Institute of Technology (IIT) … Continue reading IIT Hyderabad’s novel composite keeps tomatoes fresh for 30 days

IIT Guwahati achieves greater desalination efficiency using crystalline carbon dots

IIT Guwahati researchers have increased the efficiency of desalination to nearly 84% by using crystalline carbon dots and exposing them to simulated solar conditions. The carbon dots doped with nitrogen, sulphur and phosphorus showed crystallinity. The crystalline carbon dots retained up to 78% of the original desalination efficiency even at the end of the ninth cycle. Researchers at … Continue reading IIT Guwahati achieves greater desalination efficiency using crystalline carbon dots

IGCAR’s optical probe quickly detects urea in serum, environment

Using magnetic nanofluid emulsion functionalised with certain macromolecules (polymers) IGCAR researchers have developed an optical probe that can in less than a second detect the presence of urea in a very broad range (0.003 to 334 grams per litre). Researchers at the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam have developed an inexpensive, highly sensitive optical … Continue reading IGCAR’s optical probe quickly detects urea in serum, environment

IIT Hyderabad team fabricates e-skin for motion monitoring

Researchers from IIT Hyderabad have fabricated an electronic skin (e-skin) using carbon nanotubes deposited on a layer of PVC-free pencil eraser. The e-skin is sensitive and can simultaneously sense pressure and strain. The device can be used for human motion monitoring in the case of elderly and infants, and may ultimately find applications in flexible … Continue reading IIT Hyderabad team fabricates e-skin for motion monitoring

IISER Kolkata’s compound makes drinking water nearly free of fluoride, metal ions

The compound synthesised by IISER Kolkata researchers can reduce copper, mercury, cadmium and iron content in drinking water to below 2 ppb, which is far below the WHO limit for these metals. After 10 minutes of treatment, the fluoride concentration dropped from 10 ppm to 10 ppb. The compound can also absorb a wide variety of oils … Continue reading IISER Kolkata’s compound makes drinking water nearly free of fluoride, metal ions

IIT Bombay’s superior water filter needs very little power

Electrodes made of copper plates wound with cellulose thread coated with carbon nanotubes for capacitive deionisation and placed close to each other achieved 84% efficiency in ion removal. With power requirement of just 0.15 mW, the water filter  made by IIT Bombay researchers can be operated with a pen-torch battery. Unlike the conventionally used reverse osmosis … Continue reading IIT Bombay’s superior water filter needs very little power

IIT Hyderabad develops novel skin patch for constant drug release

A novel drug-delivery system that releases drug at constant rate for extended periods has been developed by IIT Hyderabad researchers. The transdermal patch made of patterned nanofabric and loaded with a pain killer (diclofenac sodium) with half-life of just one-two hours has been made to release for 12 hours at a constant rate. Researchers at the Indian Institute … Continue reading IIT Hyderabad develops novel skin patch for constant drug release

IIT teams developing a self test for cervical cancer

A team of researchers led by Dr. Aravind Kumar Rengan from IIT Hyderabad is attempting to quantify the visual inspection with acetic acid (VIA) technique for cervical cancer so it becomes technician-independent. The ultimate goal is to develop a self test for cervical cancer. A pap smear, a gold standard test, for cervical cancer screening may … Continue reading IIT teams developing a self test for cervical cancer
