Biotechnology has been defined as the integrated use of physical, biological as well as engineering sciences to achieve the technological application of biological systems.
Boron was discovered by Sir Humphry Davy, an English chemist, and independently by Louis-Jaques Thénard and Joseph-Louis Gay-Lussac, French chemists, in 1808. All of them isolated this element by combining boric acid with potassium.
Argon was not discovered until 1894 by Sir William Ramsay and Lord Rayleigh, even though it was suspected to be present in air by Henry Cavendish in 1785.
