"Plastic made from milk" —that certainly sounds like something made-up. If you agree, you may be surprised to learn that in the early 20th century, milk was used to make many different plastic ornaments —including jewelry for Queen Mary of England!         Plastic from milk    ~    Casein Plastic    ~    Galalith What is it Galalith? Galalith (Erinoid in the United Kingdom) is a synthetic plastic material manufactured by the interaction of casein and formaldehyde. Given a commercial name derived from the Greek words gala (milk) and lithos (stone), it is odourless, insoluble in water, biodegradable, antiallergenic, antistatic and virtually nonflammable. What is Casein? Casein is the name for a family of related phosphoproteins. These proteins are commonly found in mammalian milk, making up 80% of the proteins in cow's milk and between 20% and 45% of the proteins in human milk. Casein has a wide variety of uses, from being a major compon

What is nanostructures and basics informations about  nanotechnology Nanotechnology ("nanotech") is manipulation of matter on an atomic, molecular, and supramolecular scale. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers.  Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in nanomedicine, nanoelectronics, biomaterials energy production, and consumer products. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios.  In describing nanostructures, it is necessary to differentiate between the number of dime
