Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter of less than 1 nanometer (nm) or multi-walled (MWCNT), consisting of several concentrically interlinked nanotubes, with diameters reaching more than 100 nm. Their length can reach several micrometers or even millimeters. … Read more DMPQ-CNTs have unique thermal and mechanical properties that make them intriguing for the development of new materials. Discuss

Linear motion, also called uniform motion or rectilinear motion, motion in one spatial dimension.  According to Newton’s first law (also known as the principle of inertia), a body with no net force acting on it will either remain at rest or continue to move with uniform speed in a straight line, according to its initial … Read more DMPQ- What do you mean by Linear motion

What is catalytic converter? What is its significance. Ans:       Catalytic converters, having expensive metals namely platinum palladium and rhodium as the catalysts, are fitted into automobiles for reducing emission of poisonous gases. As the exhaust passes through the catalytic converter, unburnt hydrocarbons are converted into carbon dioxide and water, and carbon monoxide and nitric oxide … Read more DMPQ: What is catalytic converter? What is its significance.  and What is galvanisation?

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA’s instructions, or genetic code. Human DNA has around 3 … Read more DMPQ- Write a short note on the DNA structure.

A concern about what affect genetically modified material could have on human health. For example, transgenic crops have been suggested to cause allergies in some people, although it is uncertain whether transgenic crops are the source of this reaction. Furthermore the antibiotic resistance genes placed in these crops has been suggested to cause resistance to … Read more DMPQ- Explain the potential disadvantages of Transgenic crops.

Molecular farming is a new technology that uses plants to produce large quantities ofpharmaceutical substances such as vaccines and antibodies. It relies on the same method used to produce genetically modified (GM) crops – the artificial introduction of genes intoplants.A number of vaccines, antibodies and other therapeutic substances made in plants such as      tobacco, maize, … Read more DMPQ: Write short note on Molecular farming?

India’s latest communication satellite GSAT-30 was successfully launched from the Spaceport in French Guiana. With a lift-off mass of 3357 kg, GSAT-30 will provide continuity to operational services on some of the in-orbit satellites. GSAT-30 derives its heritage from ISRO’s earlier INSAT/GSAT satellite series and will replace INSAT-4A in orbit. GSAT-30 has a unique configuration … Read more DMPQ- Comment on the utility of recently launched satellite GSAT-30.

According to the several research, it was found that almost two-thirds (64%) of Indians say that they don’t exercise. Interestingly, while nearly half (46%) of consumers say that leading a healthy lifestyle is their top priority, only 37% of them actually exercise. The Fit India Youth Club, a part of the Fit India Movement envisioned … Read more DMPQ- Evaluate the need of Fit India Youth Clubs in contemporary India.

There are several ways of removing particulate matter; the most widelyused of which is the electrostatic precipitator, which can remove over 99 per cent particulate matter present in the exhaust from a thermal power plant. It has electrode wires that are maintained at several thousand volts, which produce a corona that releases electrons. These electrons … Read more DMPQ :What is electrostatic precipitator? Explain with the help of diagram.
