A fuel cell is a device which produces electric energy, through a chemical reaction. Fuel cells use positively charged ion(Hydrogen) and an oxidising agent (oxygen).There are many types of fuel cells, but they all consist of a cathode,an anode, and an electrolyte that allows positively charged( hydrogen) ions to move between the two sides of … Read more DMPQ: What is fuel cell? How Hydrogen fuel cell work? ( SCIENCE)

  Implantations of nanotransmitters and nanosensors within individuals have opened gates for monitoring and treating them at the microscopic level with the use of nanodevices. But this crosses traditional bounderies of care in the hospitals as persons can get the treatment done while siting in their homes . Pateients at home could have access to … Read more DMPQ- Nanotransmitters and nanosensors

Genome sequencing is figuring out the order of DNA nucleotides, or bases, in a genome—the order of As, Cs, Gs, and Ts that make up an organism’s DNA. The human genome is made up of over 3 billion of these genetic letters. Today, DNA sequencing on a large scale—the scale necessary for ambitious projects such … Read more DMPQ- What do you mean by genome sequencing? What are its application.

Hot Spot is an image sensing system which makes use of infra-red cameras to find out if the batsman has nicked the ball. This technology was first introduced in cricket by a Melbourne based company, BBG Sports. Although two infrared cameras are enough, generally four infrared cameras are used to record the game continuously. The … Read more DMPQ-Explain the concept behind the working hot spot technology.
