New research reveals that cultural tolerance and political pressure, rather than just biological science, dictate the life or death of tigers in India and wolves in Germany.
Scientists from Indian Institute of Technology Kharagpur (IIT Kgp) and GLA University, Mathura have developed a novel, low power humidity sensor using molybdenum disulphide nanoflakes and platinum nanocrystals.
In a first of its kind study in India, scientists from Indian Institute of Technology Bombay (IITB) and National Institute of Solar Energy, New Delhi, conducted a detailed survey at 51 locations across India to check for the degradation in the performance of photovoltaic modules. This study, to establish reliability of the modules, could help India achieve the ambitious dream of 100 GW of solar energy by 2022.
It was years ago that India’s first Prime Minister Jawaharlal Nehru had said, “It is science alone that can solve the problems of hunger and poverty, of insanitation and illiteracy, of superstition and deadening custom and tradition, of vast resources running to waste, or a rich country inhabited by starving people... Who indeed could afford to ignore science?”
Nehru was one of the first people to use the term scientific temper and advocate the promotion of scientific temper:
In an attempt to reduce their carbon footprint, many nations around the world are looking at wind energy. This form of energy is already responsible for 12% of installed power in India. An Indian Institute of Technology Bombay study predicts Indian offshore wind farms will benefit from rise in sea temperatures
The Indian National Academy of Engineering, a consortium of distinguished engineers in the country, has announced the winners of the annual Young Engineer Award 2017. With 3 awards, IISc grabbed the highest number of awards this year followed by ISRO and six IITs winning one each. The award is given as a recognition to engineering and scientific contributions in the country, with individuals selected from government, academia and industry.
Transistors are the backbone of the zillion electronic devices that we use today. While development of these semiconductor devices dates back to four decades, it's applications are ever increasing. Internet of Things is the new application that is transforming the development of transistors. In view of this, scientists at IIT Bombay and SCL ISRO have developed a new kind of Bipolar Junction Transistor that is completely indigenous. The researchers believe a home made technology can see its application in strategic sectors like space and defence.
Research at the Indian Institute of Science, Bengaluru and Vikram Sarabhai Space Centre, Thiruvananthapuram indicates that black carbon (BC) aerosol emissions from aircrafts could be impacting the stratospheric ozone layer. Aerosols are minute particles suspended in the atmosphere that interact with incoming and terrestrial radiation affecting the earth’s climate. Some aerosols, such as sulphates and, nitrates cool the atmosphere. BC, on the other hand, is a positive climate forcing agent, absorbing radiation across a wide range of wavelengths.
For over a century, India has nutured a host of science and technology based institutions. We capture the timeline of these institutions as they were established.
Smart adaptive actuators are sought after for a variety of mechanical and aerospace applications. Commonly used piezoceramic and shape memory alloy actuators produce small displacements, and hence require motion amplification mechanisms. However, these mechanisms are prone to mechanical play, and are susceptible to wear and tear.
The Indian Institute of Technology’s (IIT) are autonomous public institutions of higher education, offering undergraduate, postgraduate and doctoral courses in engineering and related domains. IIT Kharagpur was the first institute to be set up, followed by in Bombay, Madras, Kanpur and Delhi. Today, there are a total of 23 IIT’s across the country and many of these premier institutions are placed high up in institutional rankings in the country.
