IIT Bombay student develops a device to locate veins before drawing blood.

For many of us, the thought of being pricked by a needle to draw blood or inject drugs is horrifying, right? What if you had to be pierced many times because the right vein could not be identified? Nightmarish you say? Soon, this could be the thing of past, thanks to an award-winning ‘vein tracer’ by Mr. Trivikram Annamali, a student of the Indian Institute of Technology Bombay.

After graphene, carbon nanocones are now an exciting form of carbon for material scientists. As the name suggests, they are conical structures made up of carbon, where graphene sheets are folded like a party cap with a height and diameter of a few nanometers (1 nanometer = 1/1,000,000,000th of a metre). With unique properties due to their conical shape, they have a wide range of applications, including being used as a tip of the probe of a high precision microscope used to record activity at an atomic level.

A team of researchers from Indian Institute of Science, Bengaluru, Université Paris-Saclay, Gif-sur-Yvette, France and Technische Universität München, Germany has provided a material design strategy for polycrystalline piezoelectrics that could achieve electrostrain values larger than 1%. The breakthrough could result in cheaper and efficient piezoelectric actuators.
