In 1911, Rutherford and his assistants, H. Geiger, and E. Marsden, conducted the Alpha Particle scattering experiment, which resulted in the formation of the ‘nuclear model of an atom.’ α-ray Scattering … Read more
Viscosity is a measure of the resistance to flow that a liquid exhibits because of the internal friction that occurs between the different layers of the fluid. The majority of … Read more
Fractional distillation is a method of separating the various components of a chemical mixture into different parts (called fractions) based on their boiling points. In fractional distillation, a liquid mixture is … Read more
Nanolithography is a subfield of nanotechnology that refers to the process of imprinting , writing, or etching patterns on a tiny scale to build extremely small structures. Nanolithography is primarily … Read more
Nanotoxicology is concerned with determining the negative consequences of nanoparticles on human health and the environment. Nanotoxicology seeks to define and identify the hazards of manufactured nanomaterials and necessitates a … Read more
Guillaume-François Rouelle proposed an acid-base titration in 1754 as one of the titration processes. An acid-base titration is a quantitative analysis method for determining the concentration of an acid or … Read more
Titration is a typical quantitative/chemical analysis method used in laboratories to determine the unknown concentration of a known reactant (analyte). The method is based on a chemical reaction between a … Read more
A mixture is made up of one or more pure components with different ratios. Mixtures can be either heterogeneous or homogeneous. When compared to homogeneous mixtures, heterogeneous mixtures can be … Read more
The scanning tunneling microscope (STM) developed by Dr. Gerd Binnig and his colleagues in 1981 at the IBM Zurich Research Laboratory, Ruschlikon, Switzerland, is the first instrument capable of directly … Read more
