VoW! A technology to warp voice

A team of researchers from the Indian Institute of Science (IISc) have come up with a new technology that can ensure fine synchronisation between lip movement and video for voice dubbing applications in movies. Called ‘Voice Warping,’ (in short, VoW) the technology can do many other things as well: from helping you learn a new language or Carnatic music lessons, to making radio/television advertisements cheaper. It is developed by Prof. Chandra Sekhar Seelamantula who heads the Spectrum Lab at the Department of Electrical Engineering, IISc, Bangalore.

Nano-antennae: Let there be more light

Researchers at the Indian Institute of Science have recently shown that combining two of the building blocks in nanotechnology, quantum dots and nanorods, leads to enhanced light emission properties. This may find applications in novel display screens, photodetectors and solar energy applications.

Mapping mangroves, our coastal safety net

Researchers from the Centre for Ecological Sciences at the Indian Institute of Science studied four estuaries along the western coast of Karnataka - the Honnavar division of Uttara Kannada district – and showed that the area has about 3 sq. km. of mangrove forests.

A sensor for detecting proteins associated with infection

The human body encounters several harmful agents like bacteria every day, which can trigger inflammation in the body. A protein called the C-reactive protein (CRP) is produced in higher than usual amounts during infections. A team from IISc have designed an efficient, sensitive sensor to measure the levels of CRP, even in the presence of interfering agents.

Designer gates for tiny, charged particles

Control over charge/ion transport in nanosized channels is essential in realising devices based on electromechanical energy conversion, in drug delivery and in controlled catalysis. Publishing in the journal Angewandte Chemie, researchers from IISc and Jawaharlal Nehru Center for Advanced Scientific Research (JNCASR) have described how the magnitude and polarity of surface charge can be dynamically controlled.

A device that can potentially improve battery performance

Researchers from the Indian Institute of Science have developed a device that could lead to better batteries. The devices, called the ‘supercapacitor’, can store a lot of charge, be charged/discharged quickly and withstand many charge/discharge cycles. More work is needed to make it ready for the market, but the basic design is ready.
