Aerogels

This Catalyst article investigates the nature of aerogels, which are among the least dense solid materials, not much denser than air. Aerogels were made as the result of a bet and ended up going into space to capture comet dust. They are the lightest solids which exist and have some unusual features.

Printing in Three Dimensions

This Catalyst article looks at 3D printing, a new technology which is rapidly finding applications. Although probably too slow for mass production it is useful for producing prototypes and tailor-made items. In a 3D printer, layers of polymer beads are printed one on top of the other. Heat melts the polymer beads...

Hydrogen Powered Cars

As the need to find alternative cleaner forms of energy increases, scientists are looking to technologies, such as Hydrogen Fuel Cells (HFCs), as a power source for transportation.

This Catalyst article explains how hydrogen and oxygen gas can be used in a redox reaction to produce electricity, and the...
