Changing the Landscape of Geology, Forecasting Earthquakes – Professor Friedemann T. Freund, NASA Ames Research Center
Imagine a world where we knew about earthquakes before they strike – days before a potentially lethal event. A world with an early warning system that would give us time to evacuate vulnerable buildings, to activate civil defence organisations, to minimise the loss of...
Collaborating to Study Interfaces in Miniaturised Materials – SFB 1083
Creating technologies from multiple materials with different physical properties can be hugely beneficial, but the process doesn’t come without its challenges. As we fabricate new devices, an understanding of the physics occurring at the interfaces where different...
A New Generation of Chemical Sensors – Dr Simon Humphrey & Sam Dunning, University of Texas
Dr Simon Humphrey and Sam Dunning at the University of Texas at Austin have created a new lanthanide-based chemical sensor that can identify trace levels of water in many different solvents, and can even distinguish between normal water and ‘heavy water’. The team’s...
Negative Ion Formation in Complex Heavy Systems – Dr Alfred Msezane, Clark Atlanta University
When an electron is absorbed by a heavy atom or molecule, a heavy, negatively-charged ion is formed. These negative ions can be used for a wide array of useful applications, from organic solar cells to water purification. However, the electron absorption process for...
Investigating Cosmic Snowballs – Professor David Jewitt, University of California, Los Angeles
Professor David Jewitt and his team at UCLA explore the nature of comets. These fleeting visitors to our cosmic shore are important sources of information, and can help to reveal the origin and evolution of the solar system. Most recently, Professor Jewitt’s team have...
