Catalyst Volume 16 Issue 3

This issue of Catalyst includes the following articles:

Nanotechnology

Nanotechnology is the science of building tiny devices. Some people say that nanotechnology will be the answer to many of our biggest challenges - in medicine, electronics and defence. Others say that it will lead to opening up a dangerous world of technologies which could get out of control. Who is right?

Radiography - Careers

This article looks at using radiation in medicine.

Plants and Mineral Nutrients

If a plant or tree were to be burned, most of it would go up in smoke, but part of it would be left behind as ash. This article looks at the chemicals that make up the ash and the role they play in the life of the plant.

Radioactivity in Medicine

Radiation has many uses in medicine, both in finding out what is wrong with a patient (diagnosis) and in the treatment of cancer (therapy). The radiation used in medicine can come from electromagnetic radiation or from radioactive materials.

Iron

Iron is a relatively abundant element and humans have made widespread use of it for a number of centuries. This article explores the chemistry of iron.

Gertrude B. Elion

This article presents the work of a pioneer in anti-viral drugs.

Chemistry in a Blast Furnace

This article explores reactions in iron production.
