It is a pollution control system for the reduction of Sox (SO2, SO3), HCl and heavy metals like mercury. It is a dry process in which a sorbent (a material used to absorb or adsorb liquids or gases) is injected into the coal-fired boiler where it interacts with various like SOx, HCl and the resultant … Read more DMPQ-What is dry sorbent Injection Technique.

The principle used in the pressure cooker is that the boiling point of water increases with an increase in pressure. Hence option (a) is the correct answer. Pressure cooker has a confined space sealed from all side (except valve which is used to release excess pressure). When heat is supplied to the cooker it first … Read more DMPQ-What is the working Principle behind the working of Pressure cooker

Carbon dots are fluorescent nanoparticles that show similar physical and optical properties to the well-known semiconductor quantum dots. However, the building block of carbon dots is made primarily out of carbon, with some doped heteroatoms, creating a nanoparticle that is more biocompatible and less toxic compared with the quantum dots that commonly contain heavy metals. … Read more DMPQ- What is carbon date and How they are useful?

Agent Smith is a mobile malware which has infected approximately 25 million smartphones across the world out of which 15 million devices are estimated to be from India. It accesses the smartphone’s resources to show fraudulent ads for financial gains, however, it could be easily used for much more intrusive and harmful purposes like theft … Read more DMPQ- Agent Smith was recently in the news. What is Agent smith?

Antibiotic resistance is accelerated by the misuse and overuse of antibiotics, as well as poor infection prevention and control. Steps can be taken at all levels of society to reduce the impact and limit the spread of resistance. To prevent and control the spread of antibiotic resistance, individuals can: Only use antibiotics when prescribed by … Read more DMPQ- Antibiotic resistance is accelerated by the misuse and overuse of antibiotics, as well as poor infection prevention and control. Suggest ways to prevent the rise of antibiotic resistance.

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

Under the Drugs and Cosmetics Act, CDSCO is responsible for approval of New Drugs, Conduct of Clinical Trials, laying down the standards for Drugs, control … Read more DMPQ- Write a short note on Central Drug standard control organisation.

Stem cells are special human cells that have the ability to develop into many different cell types, from muscle cells to brain cells. In some cases, they also have the ability to repair damaged tissues.               Stem cells differ from other kinds of cells in the body. Self-renewal: They can divide and renew themselves for … Read more DMPQ- What are stem cells? What are the different types of stem cells and how they are utilised to treat cancer?

In zigzag kilns, bricks are arranged to allow hot air to travel in a zigzag path. The length of the zigzag air path is about three times that of a straight line, and this improves the heat transfer from the flue gases to the bricks, making the entire operation more efficient. In addition, better mixing … Read more DMPQ- What do you understand by the term Zigzag Technology?

Nuclear magnetic resonance (NMR) spectroscopy is the study of molecules by recording the interaction of radiofrequency (Rf) electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. The technique is used in quality control and research for determining the content and purity of a sample as well as its molecular structure. The … Read more DMPQ- Nuclear Magnetic Resonance Spectroscopy.
