In a society dominated by people who can independently carry out daily activities, the challenges faced by differently abled individuals are rarely acknowledged. With thoughtful design approaches, simple day-to-day activities could be made easier for such individuals. A great example of this is a novel hygiene product designed by Master students Shubham Pudke and Suyog Dhanawade under the guidance of Prof. Dibakar Sen at the Centre for Product Design and Manufacturing, Indian Institute of Science, Bangalore to aid disabled women with just one functional hand. The newly designed sanitary napkin wearing aid not only meets the hygienic demands, but also enables its use without relying on a caregiver. “Activities of daily lives are primary activities for everyone for their dignity and independence from physical support of others. It enables other family members to explore sources of earnings when the primary bread earner becomes disabled due to any circumstances”, says Prof. Sen, elaborating on the motivation for the study.

In a recently published study, scientists at the Indian Institute of Science, Bangalore, are addressing one of the biggest challenges faced by many appliances - wear and friction due to usage. Wear and friction affects the lifetime of industrial equipment, which directly correlates with the profitability of the business. The teams of researchers, led by Prof. M.S. Bobji at the Department of Mechanical Engineering are now experimenting with alumina based nanocomposite coating for wear resistance.

By sharing resources, mobile phone service providers can reduce call drop rates and make higher profits, is the conclusion of a study by researchers from the Indian Institute of Science and the University of Pennsylvania, USA. The research, though conducted a few years ago, assumes importance now, because the Telecom Regulatory Authority of India (TRAI) recently allowed different service providers to share spectrum.

The inconsistency between spatial development of Bengaluru and its urban planning has skyrocketed the cost of city development, says a new study by Ms. N S Nalini, a researcher from the National Institute of Advanced Studies (NIAS), Bengaluru. Considering the example of the water supply system in the city, the study confirms that it is inefficient with an overpriced production and supply of water. The study also suggests that planning water supply based on the natural terrain of the city could minimize these costs.

In an effort to make water resources sustainable, the Ministry of Earth Sciences, India and the Natural Environment Research Council (NERC), UK have funded a new project “Upscaling Catchment Processes for Sustainable Water Management in Peninsular India” (UPSCAPE). It is a 3-year £2 million research project that is one of the three projects in India initiated under the ambitious Newton-Bhabha Sustaining Water Resources Programme. Six institutes have come together as partners in this project, of which the prestigious Indian Institute of Science, Bangalore, is the lead Institute from India. “The motivating factor of the Newton-Bhabha project is to ensure science reaches the society and benefits it”, says Prof. Pradeep Mujumdar, Chairman at the Interdisciplinary Centre for Water Research, Indian Institute of Science. He also leads the team of Indian scientists working on the UPSCAPE project in the Cauvery river basin.

Ferroelectric materials carry a spontaneously polarized charge within their crystalline structure that can be reversed by the application of an electric field. As scientists try to shrink them to nanometre sizes, these materials often lose their polarization. Now, a collaborative research team from India and Germany has observed an unexpected effect in the ferroelectric alloy of bismuth ferrite and lead titanate (BiFeO3-PbTiO3). They have found that mechanically grinding this material to smaller sizes actually leads to a different atomic arrangement - a new structural phase that retains the polarization with slight alteration. This discovery opens up interesting possibilities for using this ferroelectric material in a variety of miniaturised devices - computer memory, RFIDs, sensors and actuators.

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.

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.
