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

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.

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

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

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

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

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
