Green Solutions

A Catalyst article about green chemistry. Many reactions take place in solution. Water is a familiar solvent but there are many others, including a rather surprising one, carbon dioxide, which is a non-polluting ‘green’ solvent. The chemical industry relies on solvents to produce many everyday products, such as:...

Hearing the World around Us

A Catalyst article about how engineers use their understanding of sound waves to develop highly realistic sound systems for films, music systems and computer games. The same ideas can help people with eyesight and hearing problems. Sound waves are affected by their surroundings and the article examines this along...

Hearing Trouble

This Catalyst article looks at 'Restored Hearing', a business which grew out of a school science project. It provides therapy for sufferers of temporary tinnitus, a debilitating hearing condition caused by exposure to loud noises. The article looks at how hearing loss can occur and how also explains how the...

Herbaria: biology's secret weapon

This Catalyst article looks at herbarium houses that contain plant specimens collected from around the world. Studying these specimens allows botanists to study how plants work and how we are impacting on the environment.
