Predicting the extent of global warming

Most of us associate global warming with greenhouse gases, which absorb radiation that is emitted by the earth. But clouds and aerosols also have a huge impact on climate change, reflecting sunlight and absorbing infrared light.

Dr Evan Robertson specialises in icy aerosol particles, including those that are found in clouds at high altitudes. Forming artificial clouds in the lab helps reveal their properties, and how they absorb and scatter radiation. His research will help to improve models that predict the extent of global warming.

Understanding gas adsorption at single-molecular level

Nitrogen fixation is the process whereby nitrogen in the form of a gas in the atmosphere is incorporated into biomolecules, such as proteins found in the human body.

Dr Dongchen Qi and Chris Wright, in collaboration with colleagues at the National University of Singapore and Brookhaven National Lab, have found a new kind of molecule that is able to aid in nitrogen fixation.

This discovery may assist efforts to artificially fix nitrogen, which is important, for example, in the industrial production of plant fertilizer.

A bright future for sensing applications

Materials that emit and absorb specific colours of light are needed for applications such as LEDs and analytical sensing.

Dr Peter Barnard, Dr Conor Hogan and Dr David Wilson have synthesised and studied a new class of brightly emitting iridium-metal based molecules that have exceptional electrochemical properties. They may form the basis for new highly sensitive chemical and bio-sensors. Read more.
