Nanotechnology & Nuclear Science Applications Quiz — 7 Free Questions

Question 1

What self-sustaining sequence of nuclear fission events, already discussed elsewhere in this pack, occurs when the neutrons released by one fission event go on to trigger further fission events in neighbouring atomic nuclei?

Question 2

What technique exposes food to a controlled dose of ionising radiation, already discussed in an earlier pack of this quiz, to kill a harmful micro-organism or insect pest and extend the food's overall shelf life?

Question 3

What fissile isotope, already discussed elsewhere in this pack, is not found significantly in nature but is instead produced within a nuclear reactor when a non-fissile isotope of uranium absorbs a neutron?

Question 4

Who was the physicist generally regarded as the father of India's nuclear programme, who founded what later became the Bhabha Atomic Research Centre, already discussed elsewhere in this pack, and conceived India's own three-stage nuclear power strategy?

Question 5

What has generally been cited as an important consideration surrounding the increasing industrial use of a nanomaterial, already discussed throughout this quiz, given the still-incomplete scientific understanding of its long-term effects?

Question 6

What instrument, generally abbreviated as AFM, images a surface at the nanoscale by physically dragging or tapping a fine probe tip across it and measuring the resulting force?

Question 7

What forms the second stage of India's three-stage nuclear power programme, already discussed elsewhere in this pack, fuelled by the plutonium produced during the first stage, also already discussed elsewhere in this pack?

About Nanotechnology & Nuclear Science Applications

This quiz is meant for students preparing for the IAS examination and other competitive tests, and for anyone who wants a thorough, well-rounded understanding of nanotechnology and nuclear science. It begins with the fundamentals of nanotechnology -- nanomaterials such as carbon nanotubes and graphene, the top-down and bottom-up manufacturing approaches, key characterisation tools, and India's own Nano Mission. A second pack covers nanomedicine in detail -- targeted drug delivery, diagnostic imaging, the lipid nanoparticle technology behind certain vaccines, and nanotoxicology safety research. A third pack covers the industrial and materials applications of nanotechnology -- energy storage, solar cells, agriculture, and nanomaterial safety and regulation. A fourth pack covers nuclear physics fundamentals -- radioactive decay, nuclear fission and fusion, and the components of a working nuclear reactor. A fifth pack covers India's own nuclear power programme -- Homi Bhabha's three-stage strategy, key institutions such as BARC and NPCIL, and India's evolving international nuclear standing. It closes with nuclear applications, safety and policy -- nuclear medicine, food irradiation, AERB, the IAEA, and a synthesis tying the whole quiz together. When complete it will have one hundred and twenty-five carefully checked questions, arranged in six packs.

Every question has four options, and the correct option can be in any position. After each question there is a detailed explanation of more than five lines, in simple Indian English that a school student can follow, giving the important names, figures and the points that examiners like to test.

Every fact has been checked against standard reference material on nanotechnology, nuclear physics and India's nuclear programme, current as of this quiz's preparation.
