Scientists Design Novel Inverters for Harnessing Solar Power

Solar power has the potential to reverse the environmental challenges faced by the world today. With solar panels becoming economically viable and efficient by the day, solar energy may soon become the prime source of electricity. However, there are a few challenges faced in the process of electricity production through solar energy. In a recent study, researchers at the Indian Institute of Science, Bangalore, have addressed one such challenge while converting the Direct Current (DC) output of solar panels into Alternating Current (AC) required to run our appliances. Dr. Abhijit Kulkarni and Prof. Vinod John from the Department of Electrical Engineering have developed a new start-up method for a compact and efficient photovoltaic inverter that works with solar panels to convert DC to AC.

Augmented Reality based App to aid Design Engineers

In a multinational collaborative study, researchers have designed a novel mobile app that can help novice designers in converting existing artifacts or mechanical objects into abstract representations. Prof. Amaresh Chakrabarti from the Centre for Product Design and Manufacturing, Indian Institute of Science, Bangalore and his team, consisting of researchers from Taiwan, have used Augmented Reality to build this tool that can aid design innovation.

Microemulsion Polymerization: Creating clean and green nano-size polymers

Nano-size polymers have made headlines in the recent years for their biological and medical applications. With dimensions of less than 100 nanometers (nm), they can carry drugs and pharmaceuticals in the body due to their subcellular size, sustained release properties and biocompatibility with our tissues and cells. But how are these nano-size polymers synthesized? In a recently written book chapter in the book, ‘Nano-size polymers: preparation, properties, application’, Prof. Manas Chanda, a retired faculty from the Indian Institute of Science, Bangalore and an expert in the field of polymers, has enunciated the direct synthesis of these tiny polymers by a method called microemulsion polymerization.

Towards a Clearer Picture in Biomedical Imaging: An Improved Algorithm for Photo Acoustic Tomography

In a collaborative study between the Indian Institute of Science (IISc), Bangalore, and the University of Twente, The Netherlands, researchers have designed a new algorithm for image recovery in Photoacoustic Tomography (PAT). PAT is an important non-invasive biomedical imaging technique where the optical contrast rendered by laser beams and the superior resolution of ultrasound waves are used to study biological tissues. The new algorithm works better with higher accuracy as compared to the conventional ones in use today.

Scientists identify strategies for Viral Marketing on Social Networks

Most entrepreneurs with a pioneer product face a common set of challenges - knowing how their product would be received in the market, finding the best strategy to advertise it and identifying the initial set of “seed users” who would use the product and provide feedback on its improvements. In the age of social media where information diffuses at massive speeds, how should one identify the set of users who have the maximum influence in reaching out to a larger crowd? In a recent collaborative study, researchers at the Indian Institute of Science, Bangalore and IBM India Research Labs have studied how information diffuses on social networks and have identified strategies to answer this question.

IISc signs an agreement with BEL for Technology Transfer

In a major move to homegrown research, the Indian Institute of Science, Bangalore, (IISc) and Bharat Electronics Limited (BEL) today signed an agreement on transferring a technology on Radio Frequency (RF) amplifiers based on Complementary Metal Oxide Semiconductor (CMOS) technology, developed at IISc. The signing ceremony took place at IISc where Prof. Anurag Kumar, Director, IISc and Dr. Ajit Kalghatghi, Director (R&D), BEL exchanged the agreement.

ISc Researcher’s New Transistor Design – Breakthrough in Chip Technology

Prof. Mayank Shrivastava of the Indian Institute of Science, Bangalore has invented and demonstrated a new transistor design, which can lead to a breakthrough in future chip technology. The proposed transistor has significantly better performance and scalability as compared to the technology used in current computer and cell phone chips.

How much water should be released from a reservoir?

Reservoirs allow water to be stored, so that it can be used whenever needed. They are very important for the irrigation of cultivated lands. However, it is important to control the rate of water release from these reservoirs, so that the water usage can be optimized according to current requirements.
