A material made by combining two or more materials, often ones that have very different properties.

A natural or synthetic material (such as a metal or polymer) that is suitable for introduction into living tissue especially as part of a medical device (such as an artificial joint).

Has an atomic structure characterized by a regular repeating three-dimensional array of atoms, ions, or molecules.

Has an atomic structure characterized by a more or less random three-dimensional arrangement of atoms, ions, or molecules.

A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

A variable that represents a quantity that is being manipulated in an experiment. The letter x is often the variable used to represent the independent variable in an equation.
