Types of plasticsPhoto: Natural plastic: Sticky tape is made from cellulose, a natural polymer found in plants. The first plastic sticky tape was developed in 1930.There are many different plastics, so we need ways of making sense of them all by grouping similar ones together. Here are a ...
Electroplating has lots of other uses, besides making cheap metals look expensive. We can use it to make things rust-resistant, for example, to produce a variety of useful alloys like brass and bronze, and even to make plastic look like metal. How does this amazing process work? Let's ...
First, because graphene has so many excellent properties, and because all those properties probably aren't needed in the same material (for the same applications), it makes sense to start talking about different types of graphene (or even different graphenes) that are being used in different ...
As their name suggests, narrow-band pyrometers capture a much smaller and more specific band of radiation, typically using photocells. Exactly which radiation band you need to sample depends on the temperatures (and materials) you're trying to measure (the hot alloys in jet engine turbines ...
