She also performed important research into the polio and TMV viruses. The tool focuses a laser — using mirrors and optical fibers — onto a surface containing a fingermark.
Physical chemists study how matter and energy interact. Additional reporting by Traci Pedersen, Live Science contributor. Biochemists must understand genetics, chemistry and business needs to develop crops that are easier to transport or that have a longer shelf life.
Sir Humphry Davy - Sir Humphry Davy is best known for using electrolysis to isolate and discover many elements. At one time, he held nearly patents on various items.
The rate at which chemical knowledge continues to accumulate is remarkable. She was the first woman to win the Nobel Prize and won the award twice, once for physics in and again for chemistry in Environmental chemists must first understand the chemicals and chemical reactions present in natural processes in the soil water and air.
Thus chemistry involves the study of the atomic composition and structural architecture of substances, as well as the varied interactions among substances that can lead to sudden, often violent reactions.
