Chemical Engineers
Using chemistry, biology and physics, chemical engineers solve problems related to such products as food, drugs and chemicals. For example, they discover fertilizers and pesticides to protect and enhance food growth and create technologies used to combat pollution in the air, soil and waterways. Chemical engineers also design medical devices that can function as artificial organs and they engineer drug-delivery systems. In addition, chemical engineers develop semiconductor chips used in phones, cars, and communications satellites and they are responsible for the polyethylene used in milk bottles, as well as Kevlar – which is used in lightweight bulletproof vests
