This issue of Catalyst contains the following articles:
The Most Accurate Thermometer in the World
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.
Essential Oils as Antimicrobial Agents
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.
Saving Lives While Cooking Lunch
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 - the Perfect Nuclear Fuel?
Thorium can be used as the fuel in a fission reactor - and it appears to be much safer than uranium.
Try This - the Thermal Decomposition of Sodium Hydrogen Carbonate
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.
Catalyst is a science magazine for students aged 14-19 years. Annual subscriptions to print copies of the magazine can be purchased from Mindsets.

Saving Lives While Cooking Lunch
Traditional cooking stoves burn fuel and produce a lot of smoke which is a major cause of pollution, leading to problems locally for the people using the stoves and also globally as a probable cause of retreating glaciers. According to the World Health Organisation, four million people worldwide die each year from...
Thorium - the Perfect Nuclear Fuel?
This Catalyst article looks at thorium - a heavy element, similar to uranium. Some people think that it could be the nuclear fuel of the future, as it can be used as the fuel in a fission reactor - and it appears to be much safer than uranium.
This article is from Catalyst: Secondary Science Review 2014,...
Try This - the Thermal Decomposition of Sodium Hydrogen Carbonate
This Catalyst article investigates how honeycomb (cinder toffee) is made using a thermal decomposition reaction to produce the gas bubbles. Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down...
Scientific Volunteers
This Catalyst article outlines volunteering opportunities for young scientists, engineers and medical students who put their studies to good use, working with local people around the world to bring the benefits of technology to communities who otherwise would go without some of the basic needs of life.
