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

Big data is the huge amount of data which is present in an unprocessed way. It is a complex data. Big data is characterised by 3 Vs ie. Volume of data, velocity of data i.e. processed and complex variety of data. Big data has various useful application. The application of Big data can be seen … Read more

Distillation is a water purification method that utilizes heat to collect pure water in the form of vapor. This method is effective by the scientific fact that water has a lower boiling point than other contaminants and disease-causing elements found in water. Water is subjected to a heat source until it attains its boiling point. … Read more

Neutrinos are the elementary particles found in the universe, which have no charge and have very little mass. They are electrically neutral and have weak interactive force. They are generally formed in the nuclear core of the sun. Radio active decay is also one of the source of neutrinos. They have the unique property of … Read more
