About the Consortium:

  • Reportedly, the new strain SARS-CoV-2 found in Britain is 70 percent more infectious than the original strain though nothing is confirmed about its virulence yet. Meanwhile surveillance has increased at the international airports in India and RT-PCR test has been made mandatory for the passengers arriving in India from UK.
  • Taking strict action in this regard, the Indian government has also established a consortium to monitor the genomic variations in the SARS-CoV-2. On a regular basis, 10 labs have been selected to do genome sequencing of the new strain.
  • 10 laboratories of the consortium include research institutes and centre like National Centre for Disease Control (NCDC), Delhi, National Institute of Biomedical Genomics, Kalyani, Kolkata and CSIR Institute of Genomics and Integrative Biology (CSIR-IGIB), Delhi. Among these DBT - National Institute of Biomedical Genomics, Kalyani, Kolkata and CSIR Institute of Genomics and Integrative Biology (CSIR-IGIB), Delhi will maintain a national database of all the genomic sequencing data while NCDC will maintain a database of all the samples of new variants which are of public health significance.
  • Genome sequencing of all the covid-19 positive flyers who arrived in India between 9th and 22nd December is being done in theses labs to get accurate data on the presence of a new strain. According to the available data about 33,000 people from the UK came to India between 25th November to 23rd December.
  • These people are being tracked to get them tested and to perform genomic testing on the positive samples. More than 200 people have been found to be covid-19 positive and at least 25 have been infected with the new strain. The patients are under isolation and the recent contacts have been quarantine to control the spread.

3. METAL CO2 battery for MARS MISSION

Context:

In 2013, India launched its first mission to Mars and became the first country in the world to enter the Mars orbit in its very first attempt. Now India is preparing for second mission to Mars which is planned for the year 2020. To make this mission more affordable and efficient Indian researchers at IIT Hyderabad are working on the development of metal carbon dioxide battery which according to them can reduce the mass of the payload.

Metal Carbon Dioxide Battery for Mars Mission (E)

About the battery:

  • Efficient energy storage systems are critical for space missions. Currently, lithium-ion batteries are used by space agencies like ISRO. Though, there is a need for better options demonstrating high energy density and improved cyclability.
  • In view of this, researchers at IIT Hyderabad’s Department of Chemical Engineering led by Associate Professor Shekhar Sharma are working on a metal carbon dioxide battery to develop improved energy storage systems. According to the researchers, metal CO2 batteries can be 10 times more efficient especially in the case of mars mission as such batteries can use CO2 directly as a fuel which is present abundantly on the red planet.
  • Professor Sharma has also developed a coin cell prototype of the Metal-CO2 battery at the institute’s carbon laboratory. The technical feasibility of this battery was demonstrated in the simulated Mars environment created in the lab where the porous cathode of the cell used the C02 from the atmosphere and converted it into electrical energy as the Martian atmosphere contains up to 95 percent of CO2. So, the realization of such batteries will prove to be a boon for any Mars mission.
  • The successful development of this technology can provide lander and rover of the future Mars mission with efficient energy systems as the battery will use Martian CO2 as a fuel so less battery will be needed which will reduce the mass of payload as well as the cost of the launch. Moreover, this technology can also be used to fix increased CO2 emissions on the earth as they are a major cause of global warming. CO2 can be stored in such batteries without the need to convert it in any other form.
  • The study was published as a featured letter in the journal ‘Materials Letters’ and looking at the novel purpose of the research, the team has also filed for an Indian patent. The researchers plan to involve government organizations like ISRO in the early phase of the real battery prototype for timely inputs to implement this technology successfully.
