Catalyst Volume 24 Issue 3
This issue of Catalyst contains the following articles:
This article looks at how a highly accurate thermometer measures temperatures by finding the speed of sound in a gas.
This article looks at the work of three chemists who won the 2013 Nobel Prize for Chemistry for devising a method for producing models of complex molecules.
A school microbiology club investigates the antimicrobial effects of some essential oils.
This article investigates aerogels, which are amongst the least dense solid materials and are not much denser than air, and their surprising properties.
This article describes how humans can misjudge the weights of small dense objects and large, light objects and how human perception of weight is easily fooled.
This article investigates how a more efficient stove is an example of appropriate technology - it produces less hazardous smoke and can generate electricity too.
Thorium can be used as the fuel in a fission reactor - and it appears to be much safer than uranium.
Bicarbonate of soda decomposes on heating - it is used in the making of cinder toffee.
This article looks at volunteering opportunities for students where can use their skills to help communities around the world.
Almost every scientific experiment or industrial process requires a measurement of temperature. For example, the specification of the length of an object is meaningless without reference to the temperature at which the measurement was made. And all chemical and biological processes are intrinsically temperature-...
This Catalyst article presents the work of three chemists - Martin Karplus, Michael Levitt and Arieh Warshel - who won the 2013 Nobel Prize for Chemistry. Their work allowed the development of complex computer models of compounds and reactions.

Since the discovery of antibiotics, many people believe that the pathogenic microorganism threat to the population has been removed, with fatal infections and infectious diseases brought under control. This has discouraged research into drugs containing natural compounds such as essential oils. However, humans are...
