Twinkle twinkle little star, how to get an electric supercar
The earth provides enough to meet the expectation of every mans need but not every mans greed, said Gandhiji. Demand of electricity is increasing globally and the intake of energy is faster than it can be produced. This highlights towards the development of an effective method that systematize production, storage and transport of energy in a smart way. It is practically challenging to store enerny in form of electricity in haste. Batteries have high energy density which keeps our devices working for the whole day, but due to their low power density, it takes hours to recharge them. On the other hand capacitors can be charged quickly but it stores a small quantity of power. We require a device which can store and release huge amount of charge rapidly, and here we turn to SUPERCAPACITORS that bridge the gap between the conventional capacitor and rechargeable batteries by performing high charge-discharge rates, extensive no. of cycles and having high power density which enables to recover energy in heavier duty systems.
Gita did her Masters in Organic Chemistry, she is currently pursuing PhD at NMIMS University, Mumbai where she works on development of commercially feasible cost-effective supercapacitors. She is a cheerful fun-loving girl who is passionate about exploring science and dreams to become a professor with her love towards explaining science in a creative approach. Further, she has also worked on a DST-SERB sponsored project titled Development of Synthetic Methodology for the Construction of Libraries of Constrained Analogues of Bioactive Molecules.
The field of Science Education: Opportunities and Challenges
With the advent of modern science and with realization of its socio-economic and political importance, science education became an important mandate of basic and higher institutions of learning. Issues of quality and deficiencies in learning observed led to establishment of the field of science education research. A field which draws from numerous disciplines of sciences, philosophy, psychology, sociology, cultural studies, history, arts to name a few; the field continues to grow steadily and offers great opportunities to scholars from diverse fields and viewpoints. The challenges in the field stem from the fact that the objects of study are the (diverse) human beings (as students and teachers) and their diverse understanding of the objects of nature, and of the domain of knowledge called science.

Storing the Energy, Securing the Future
30 November 2015, presidents and prime ministers from over 150 countries assembled in Paris, not for terrorism...not for cancer...but for climate change. It's time to think What kind of environment do we want to give to our next generation; a better world or atmosphere with toxic gases? I think the renewable energy resources, like sunlight, geothermal heat, wind, tides, water and various forms of biomass, will play a vital role to satisfy India's growing energy demand. Hence, for the effective use of renewable energy resources, one must have a cost-effective energy storage system. Lithium-ion batteries are a very promising choice for energy storage due to its high energy density, power density, good temperature range, relatively long battery life and operating voltage. The excess energy generated by renewable energy resource over and above the load requirement is used for charging the battery. The energy stored in the battery will be used to supply power during the night and to meet the excess load demand (i.e. beyond the renewable energy resource generation capacity) during the day.
Mayur's dream of becoming a strong research professional led him to the Indian Institute of Technology (IIT) Bombay in Mumbai, where he now works on Modelling & numerical simulation of Solar-PV- battery integrated performance models. He demonstrated research capability during Masters at National Institute of Technology Calicut where his dissertation was on Development of higher order numerical simulation models for solving Burgers' equation. Mayur did his Bachelors in Mechanical Engineering. Mayur is a science communicator and love to explain scientific concepts to the common public. He won the FameLab India and became the first Indian to represent India in the FameLab International 2017 at the Cheltenham Science Festival in the UK. He was the finalist for EURAXESS Science Slam India 2017. His recreational pursuits include theater, dance and music.
Did you know there are over 700 satellites in orbit just around our planet alone doing some or the other form of remote sensing? The term 'Remote sensing' refers to and also literally translates to 'sensing from a distance.' When you touch a pan on the stove to see if it's hot or not, you sense its temperature by direct contact. On the other hand, imagine a situation with an iron furnace in place of the pan! Direct contact would be dangerous, and we use infrared thermometers to sense temperature from a distance. Every spacecraft that visits a planet, an asteroid or a comet carries a multitude of sensors that sense it from a distance and send their observations back to us allowing us to study these new worlds. These sensors can take measurements much beyond what the human sensory system is capable of. Moreover, these sensors record and pour their observations as a massive volume of data which is not something a human can sift through. Here machine learning algorithms come to the rescue as it helps us find patterns in data, testing hypothesis and conducting analysis that lead to exciting finding and discoveries. Some recent works also demonstrate efficient storage and transfer using learning algorithms. Remote sensing is the primary way we observe and study our universe. Astronomy, microscopy and even the recent gravitational waves observation also fall under its umbrella.

In today's world of collaborative research, its just not enough to be “good” at science, but, it is equally important to be strongly connected to other researchers in our vicinity. A well connected academic network is like a two-edged sword. Firstly, it helps propagate ideas among the researchers, and secondly, it makes space for more information to reach the individuals new to this field.
Most often, we discover that due to poor communication and networking, the same problems continue to persist from one "batch" of researchers to the next. And, not surprisingly, most of them can be solved just by speaking and exchanging ideas with each other.
So, through “Science Talks”, we can create platforms where everyone shares, and learns together.
Please register your city, and let the talks begin!!!
It’s said that “Success is where preparation and opportunity meet”. However, most often, the gap between the two becomes difficult to bridge due to a dearth of platforms that can provide necessary information regarding opportunities available in terms of PhD positions, scholarships, academic jobs, etc. Consequently, Go for Science was launched as a platform in order to overcome this very gap. It provides a unique and exciting blend of information regarding scholarships, PhD positions, etc. and first hand experiences of scholarship holders and students pursuing higher studies across the globe. In other words, GfS ensures that potential young talents not only get sufficient knowledge about opportunities (such as scholarships, PhD positions, internships, etc) “straight out of the books”, but also get a feeling of “real life experiences” that students share on the website.
As of now, quite a number of students have already benefitted from GfS’s plethora of information regarding opportunities in scientific research, and have set out towards achieving their dreams. Therefore, looking at the overwhelming response from students, it aims to further expand its knowledge base, not only in terms of providing information regarding scholarships etc, but also enriching it with several first hand experiences of students.
