Liquid Phase Exfoliation 10th anniversary Workshop

2nd August 2018
Science Gallery, Trinity College Dublin

In August 2008, we published a paper in Nature Nanotechnology describing a new method to produce defect-free graphene nanosheets in liquids. Dubbed liquid phase exfoliation (LPE), this method used ultrasonic energy to separate few-layer graphene nanosheets from their parent crystal in certain stabilising solvents. We showed that the resultant dispersions could be used for further study or processed into functional structures. Little did we know how far this curiosity-driven, side project would go over the subsequent decade. Since those humble beginnings, LPE has been extended beyond graphene to produce nanosheets from a host of layered compounds including MoS2, BN, MoO3, Ni(OH)2, phosphorene and many other 2D materials. Exfoliation techniques have been expanded to new, more scalable processes, notably using industrial high shear mixing techniques. A key element to the success of LPE has been that working in liquids allows researchers to apply an array of processing technologies to modify, select and dispense the nanosheets. For example, while in the early days, films were prepared by vacuum filtration, we can now fabricate patterned structures using advanced printing technologies with near-micron precision. These developments have led to breakthroughs in a number of applications areas, notably composites, energy storage devices and electronics. At this point, it is worthwhile pausing to take stock of what LPE has achieved, where it is today and how best it can be developed into the future. To achieve this, we are organising a 10th anniversary one day workshop to be held in Trinity College Dublin on the 2nd of August 2018. We would very much like to see you there!

Physoc Lecture

Our very own Aline Vidotto is coming to Physoc this week to present "How Exoplanets are Affected by their Host Stars". The event will take place in the Schrodinger Lecture Theatre at 7:30pm this Thursday 22th February. The Facebook event can be found here: . As usual, the talk will be followed by a modest reception in the Fitzgerald library. The abstract for the talk is below:

"One of the most important lessons learned from the discovery of more than 3000 exoplanets (and counting) is the large diversity of planetary systems encountered in nature. In this talk, I will overview some of the surprising trends that have emerged from exoplanet searches. I will then describe how exoplanets can be affected by their host stars and will show that there are interactions between host stars and exoplanets that have no parallel in the solar system."

Science on Tap

Our 'Women in Science' event is taking place next Monday November 27th in Kennedys Pub at 7:30 pm where Dr Annie Curtis from the RCSI will tell us about Circadian Rhythms in Immunology; discover the link between your sleeping habits and health! We are also very lucky to have Dr Romina Charifou speaking about Nanoscience and Dr Sahar Alialy will tell us about her life in science-a pathway to physics and neuromorphics!

At 7 pm on Tuesday November 28th in the Liquor Rooms Dr. Stephen Dooley will speak about ammonia as a carbonless energy carrier in his talk 'Amoaning about Climate Change? Can a nitro energy be the answer?', followed by Dr. Stefan Hutzler, Physicist and foam expert, who will take us through the Science of the Pint itself! And why not have a pint or two while you're there? 

More information about these two events can be obtained from our Facebook pages and website; 

These events are free but tickets are required (due to limited capacity in the pubs). Tickets can be booked from the following links:

Night Course: The Geomagnetic Apocalypse

Space weather describes the dynamic conditions in Earth's outer space environment in the same way that weather refers to conditions in Earth's lower atmosphere. Whilst everyday space weather will not be noticeable to most people, a severe space weather event can significantly impact a multitude of vital ground- and space- based technologies and infrastructure on which we depend as part of our daily lives.

Dr Sophie Murray from the School of Physics will be explaining all about space weather on November 15th as part of the Science Gallery Night Course for the End of the World. Her talk will debunk the myths surrounding solar eruptions and geomagnetic storms, explaining what exactly space weather is: its origins at our Sun, potential impacts on Earth, and the steps we are taking to mitigate severe events. Tickets are available on the Science Gallery.
