Trinity College Dublin
Researchers at CRANN (The Centre for Research on Adaptive Nanostructures and Nanodevices), and the School of Physics at Trinity College Dublin, today announced that a magnetic material developed at the Centre demonstrates the fastest magnetic switching ever recorded.
The team used femtosecond laser systems in the Photonics Research Laboratory at CRANN to switch and then re-switch the magnetic orientation of their material in trillionths of a second, six times faster than the previous record, and a hundred times faster than the clock speed of a personal computer.
This discovery demonstrates the potential of the material for a new generation of energy efficient ultra-fast computers and data storage systems.

Researchers at AMBER, the SFI Centre for Advanced Materials and BioEngineering Research, and from Trinity s School of Physics, have developed next-generation, graphene-based sensing technology using their innovative G-Putty material.
The team s printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an important metric seen as a game-changer in the industry: flexibility.
Maximising sensitivity and flexibility without reducing performance makes the teams technology an ideal candidate for the emerging areas of wearable electronics and medical diagnostic devices.
The team - led by Professor Jonathan Coleman from Trinity s School of Physics, one of the world s leading nanoscientists - demonstrated that they can produce a low-cost, printed, graphene nanocomposite strain sensor.

A team at Trinity College Dublin is currently exploring medical applications for its flexible graphene-based sensor.
Graphene has been hailed as a ‘wonder material’ as it is incredibly strong, but also light and flexible.
Now, scientists in Ireland are making use of these properties with a development that could have applications in the areas of wearable electronics and medical diagnostic devices.
Researchers at Trinity College Dublin’s School of Physics and at AMBER, the Science Foundation Ireland research centre for advanced materials, have developed a next-generation graphene-based sensing technology.
A laser to generate randomness for next-gen information security and encryption
2nd March 2021
Scientists from Trinity’s School of Physics, with collaborators at Yale University, CentraleSupelec, France, and Nanyang Technological University in Singapore, have developed a tiny chip-scale laser system to harvest quantum fluctuations in semiconductor lasers on ultrasmall scales at unprecedented speed.
The new technology can be used to underpin modern technologies’ requirements for randomly generated digital information.
Their technique, published today in
Science, uses a specially designed hour-glass-shaped semiconductor laser to generate hundreds of tiny, random light waves that when detected with a device called a photodetector, can be transformed into random strings of ‘1’s and ‘0’s, or binary code, which is at the foundation of modern digital communications.
Led by researchers in Trinity’s School of Physics, the Trinity researchers undertook the project as a result of an open competition by TOTAL, where their proposal welcomed several applications from research teams across the globe.
The research was funded by TOTAL Marketing Services and supported by MaREI, the Science Foundation Ireland Research Centre for Energy, Climate and Marine.
The scientific work carried out by Trinity was focused on determining systematically what makes some molecular structures better octane boosters that others. By modifying these structures and adding molecular components as if they were LEGO pieces, the researchers were able to calculate if a given structure met the theoretical principles to become an efficient octane booster.
