Irish researchers create wearable sensors using rubber bands
Researchers at the School of Physics, Trinity College Dublin and AMBER, the Science Foundation Ireland funded materials science centre, have discovered a method of creating wearable sensors by adding graphene to shop-bought rubber bands; the first time this has ever been achieved worldwide. Working with researchers from the University of Surrey, their findings have been published in ACS Nano, a leading international nanoscience publication.
The team - led by Professor Jonathan Coleman, infused rubber bands with graphene, a nano-material derived from pencil lead which is 10,000 times smaller than the width of a human hair. This process is simple and compatible with normal manufacturing techniques. While rubber does not normally conduct electricity, the addition of graphene made the rubber bands electrically conductive without degrading the mechanical properties of the rubber. Tests showed that, any electrical current flowing through the graphene-infused rubber bands was very strongly affected if the band was stretched. As a result, if the band is attached to clothing, the tiniest movements such as breath and pulse can be sensed.
The discovery opens up a host of possibilities for the development of wearable sensors from rubber, which could be used to monitor blood pressure, joint movement and respiration. Other applications of rubber-graphene sensors could be in the automotive industry (to develop sensitive airbags); in robotics, in medical device development (to monitor bodily motion), as early warning systems for cot death in babies or sleep apnoea in adults. They could also be woven into clothing to monitor athletes’ movement or for patients undergoing physical rehabilitation.
The discovery was welcomed by Minister for Research and Innovation Damien English TD who said, "This exciting discovery shows that Irish research is at the leading edge of material science worldwide. AMBER is one of a number of research centres funded by the Government to carry out world-class research in collaboration with industry in strategic areas of opportunity for Ireland. Material science underpins a wide range of market opportunities that have the greatest potential to deliver economic return through enterprise development, employment growth and job retention in Ireland. This discovery is a key stepping stone in our strategy of turning good ideas into good jobs. I congratulate Professor Coleman, his team and collaborators at AMBER for this great discovery and wish them well for the future."
Professor Jonathan Coleman, AMBER, said, “Sensors are becoming extremely important in medicine, wellness and exercise, medical device manufacturing, car manufacturing and robotics, among other areas. Biosensors, which are worn on or implanted into the skin, must be made of durable, flexible and stretchable materials that respond to the motion of the wearer. By implanting graphene into rubber, a flexible natural material, we are able to completely change its properties to make it electrically conductive, to develop a completely new type of sensor. Because rubber is available widely and cheaply, this unique discovery will open up major possibilities in sensor manufacturing worldwide.”
Corresponding author, Dr Alan Dalton from the University of Surrey continued, “Until now, no such sensor has been produced that meets needs and that can be easily made. It sounds like a simple concept, but our graphene-infused rubber bands could really help to revolutionise certain aspects of healthcare.”
Professor Mark Ferguson, Director General of Science Foundation Ireland and Chief Scientific Adviser to the Government of Ireland said, “Congratulations to Professor Coleman and his team on this discovery. Science Foundation Ireland is committed to funding impactful research which will lead to new products and services of the future. Just over a year since it was established as an SFI Research Centre, AMBER’s researchers are working to address the big issues facing modern society – across healthcare, energy, transport and other areas. It is this type of research that has led to Ireland’s international position as 3rd for nanoscience and 6th for materials science. I look forward to future developments from this team.”

Physicists Reveal Quantum Effects in Biological Oxygen Transport
Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well characterised protein found in muscle to develop a new picture of how biomolecules transport and store oxygen (O2). In doing so, the international team have shown how the process of respiration, which is fundamental in humans and other vertebrates, exploits quantum mechanical effects working on tiny scales.
The physicists’ discovery, building on a number of years of intense collaboration on theory and software development, has solved a long-standing problem at the interface of chemistry and biology. At the same time, they have demonstrated a new way by which quantum mechanics can be used to answer biochemical questions, with implications for inspiring drug-related research and further interdisciplinary collaborations.
Assistant Professor in Physics in the School of Physics at Trinity College Dublin, Dr David O’Regan, said: “This work helps to illustrate the fact that quantum mechanical effects, which may sometimes be viewed as somehow very exotic or only relevant under extreme conditions, are at play in the day-to-day regimes where biology, chemistry and materials science operate.”

RESEARCHERS DISCOVER WORLD-FIRST NEW MATERIAL WHICH COULD REVOLUTIONISE INFORMATION TECHNOLOGY
New ‘MRG’ material could lead to superfast technology and energy efficient data storage 25 years in the making and discovered by researchers at AMBER, Trinity College Dublin
Scientists at AMBER, the materials science centre based at Trinity College Dublin have discovered a completely new material, which could revolutionise information technology, computer processes and data storage. The world-first discovery was led by one of Ireland’s most highly-cited researchers Professor Michael Coey, a Principal Investigator at AMBER from Trinity’s School of Physics. The Centre is funded by the Department of Jobs, Enterprise and Innovation through Science Foundation Ireland.
The research group led by Prof. Coey has created a completely new alloy of manganese, ruthenium and gallium, known as MRG. MRG is a strange new magnet; internally it is as magnetic as the strongest magnets available today, yet seen from the outside it barely appears magnetic at all. This world-first material (technically known as a “zero-moment half metal”) will initiate a completely new line of materials research and could open up numerous possibilities for electronics and information technology.
research and could open up numerous possibilities for electronics and information technology. The potential applications of MRG are many. It could lead to limitless data storage, resulting in huge, superfast memory in personal computer devices. It could also eliminate the potential of external magnetic forces to ‘wipe’ computer data. Finally, MRG could have major implications for the Big Data revolution. Commenting on the discovery, Michael Coey said, “Magnetic materials are what make reading and storing data – either on personal devices or on large scale servers in data centres – possible. Magnets are at the heart of every electronic device we use – from computers and laptops to tablets, smartphones and digital cameras. Given its unique insensitivity to magnetic fields, and the tenacity of its internal magnetic properties, MRG could now revolutionise how data is stored, which could have major implications for the future development of electronics, information technology and a host of other applications.”
For 25 years, researchers worldwide have grappled with how to create a magnet such as MRG by trying to arrange numerous combinations of atoms in a way which was difficult without flouting the basic principles of physics. Now, AMBER researchers have solved this problem, by using established industry-standard processes for making the electronic circuits on silicon chips. MRG could therefore be adopted by computer and electronics companies relatively easily.
Minister for Research and Innovation Seán Sherlock TD welcomed the announcement and said, “Here is a Government-funded research centre discovering innovative solutions to problems faced by the technology industry. I would like to praise the work of Prof. Coey and his team on this world first which opens up a range of potential applications in the electronics and information technology sectors.”
Professor Mark Ferguson, Director General of SFI and Chief Scientific Adviser to the Government of Ireland said, “SFI Research Centres like AMBER, were established with a focus on delivering cutting edge, internationally excellent research, which will deliver real benefit to the economy and to industry. This discovery absolutely fits the bill and I congratulate Professor Coey and his team. Their discovery is a world first which could solve one of the major problems faced by the technology industry worldwide. This is the type of research which Ireland is, and will continue to be recognised for.”

Transferring Thin Films onto Arbitrary Substrates
Researchers in AMBER, the Science Foundation Ireland funded materials science centre headquartered at Trinity College Dublin have developed a general method of transferring thin and ultrathin (< 100 nm) hybrid films onto arbitrary substrates. Applicable substrates include hole structures, curved surfaces, flexible substrates, and so on.
Professor of Materials Physics Werner Blau and Research Fellow Yong Zhang at Trinity’s School of Physics are the lead researchers. The discovery will offer a facile route for production of functional films directly on desired substrates/surfaces. The films have potential applications in transparent and flexible electronic and photonic devices. Flexible electronics and photonics represent the future of consumer electronics, sensors, displays, power generation and lighting. Especially its extension to printed electronics is a revolution, following in line with previous electronics industry innovations. This is a disruptive technology that will create new applications, and change and improve the way we use technology in future.

The Drop Heard Round the World
Shane Bergin, Stefan Hutzler, & Denis Weaire share their thoughts on the Trinity Pitch Drop in an article published in Physics World.
Begun in October 1944, the Pitch Drop experiment, at Trinity College Dublin's School of Physics, is one of the world's oldest continuously running experiments.This curiosity of an experiment demonstrates that pitch is a material that flows - albeit it with an incredibly high viscosity. Whilst pitch has been dropping from the funnel since 1944, nobody had ever witnessed a drop fall - they happen it happens roughly only once in a decade! In May 2013, with the latest drop about to fall, Prof. Shane Bergin broadcast the experiment via the web. On July 11th 2013, the drop dripped. You can see a time lapse video of this here. Tracking the evolution of the drop, Profs. Weaire & and Hutzler, and Mr. David Whyte calculated the viscosity of the pitch to be 2x107 Pa s - approximately 2 million times the viscosity of honey.
The time-lapse video has attracted considerable global media attention. Discover Magazine named the Trinity Pitch Drop in their top 100 science stories of 2013 & a feature article in Nature News was the 3rd most-read piece on their website in 2013.

Dr. Finch's Final Lecture
On 2nd April 2014 Dr Eric Finch (School of Physics) gave his last undergraduate course lecture. The photograph shows him on this occasion with the Senior Freshman class at the end of their Nuclear Physics course. His university teaching career spanned 45 years; after leaving Oxford he spent three years at Durham University in a post-doctoral position before coming to Trinity in 1972. As well as laboratory and tutorial classes his lecture courses in recent years have included Waves, Light and Sound to Junior Freshman non-physicists and, for physicists, Nuclear Physics to Senior Freshmen and Junior Sophisters and Semiconductor Devices to Senior Sophisters.
In 2007, Eric received a Provost's Teaching Award in recognition for his 'outstanding contribution in the pursuit of teaching excellence'. Armed with demonstrations, anecdotes, a tuning fork, and historical oversight, his lectures proved popular with undergraduate students. Indeed, his 'dancing Doppler' demonstration appeared on YouTube in 2006 with over five thousand views to-date.
The 2013/14 Senior Freshman class (as seen in the photograph) gave Dr. Finch a fitting send off following his last lecture with cards, cakes, a standing ovation and well wishes from them underlining their appreciation for his teaching skills.

Trinity Physicists Launch Citizen Science Project to Let Everyone See the Sun
From time-to-time, the Sun throws out huge solar storms in the direction of planet Earth. When these storms hit our planet, they can cause spectacular displays of the Northern Lights, but sometimes the effects can be more serious – knocking out power grids, interrupting GPS and radio communications and damaging satellites.
Now, a team of scientists from Trinity College Dublin and Zooniverse have developed a website that enables members of the public to take part in an exciting and ambitious quest to understand sunspots and how they produce solar storms.“Even the most advanced computer software is not been able to accurately work out how explosive a particular sunspots is, which is why we need your help”, according to Prof. Peter Gallagher of Trinity. But you’d be right to ask, why can't scientists do the classifications themselves? The answer is that there is just far too much data!
“Sunspotter volunteers will be the ones to thank for putting in the hard work and improving our ability to classify sunspots and predict solar storms” says Trinity’s Dr. Paul Higgins, lead scientist for the project. Sunspotter.org has been developed by Zooniverse, home of the largest, most popular and most successful citizen science projects.
The organization grew from the original Galaxy Zoo project and now hosts dozens of projects that allow members of the public – “citizen scientists” – to participate in real research. As of February 2014, the Zooniverse community consisted of more than 1 million volunteers. “The Sunspotter.org website gives members of the public the power to contribute to cutting-edge scientific research and help scientists to better understand explosions on the Sun and how they effect us here on Earth”, according to Dr. Higgins.

TCD Physics Postdoctoral Researchers Forum
Trinity College Dublin’s Physics Department has just been awarded Juno Practitioner status by the Institute of Physics in recognition of its best practice for taking action to address gender inequities across its student and staff body.
Juno Chair, Eithne McCabe, commented that the School recognised the vital role that TCD Physics postdoctoral researchers can play in advancing Juno. Gathering data from all seven Irish University Physics departments she showed that TCD Physics employs nearly half of Ireland’s University Physics postdocs. Therefore any changes in the working culture of Physics postdocs will affect a significant percentage of postdocs nationally. Eithne’s qualitative survey data from Physics postdocs illustrated the need for better communication and integration within the School and she identified the initiation of a postdoc forum and its integration into the School structure as one of the key Juno action plans for the School.
Shane Bergin has extensive experience with postdoc issues and chaired a very successful first postdoc forum meeting on January 30. He will be supported in this role by Evie Doherty. The forum will meet again one month from now. Agenda items/issues should be addressed to email@example.com or firstname.lastname@example.org.
CERN campaign launch was a smashing success
Students from the physics and maths societies in Trinity College Dublin launched a campaign on Thursday 30th January for Ireland to become a member of CERN. The launch consisted of a series of rapid-fire, Ignite-style talks, given by a diverse range of campaign supporters, including Sean Kelly MEP, Prof. Ronan McNulty of UCD (a CERN collaborator) and an industry representative (Diarmaid Mac Muthuna of Agtel). The campaign hopes to convince people of the many benefits of CERN membership to Ireland - such as the long-term economic gain as well as opportunities in science and engineering for Irish citizens.
The students launched the campaign website (http://irelandforcern.org/ ) with sections for teachers and children to learn more about CERN and also offers some of the main ideas behind the campaign. The campaign team hope to now work with other societies from universities across Ireland to hold outreach events and public talks about CERN. Minister Sean Sherlock responded to the launch saying he will review the benefits of CERN membership.

Apples and Atoms
Ernest T. S. Walton studied at Trinity where he was a scholar and won many College prizes, including a gold medal in experimental science. He graduated with joint honours in mathematics and physics in 1926 and obtained his master’s degree in 1927 after which he went to Cambridge to do a PhD. It was in Cambridge that the momentous collaboration between Walton and his fellow physicist, John Cockcroft, later began. They exploited linear acceleration methods to induce nuclear disintegration by artificial means, as observed by Ernest Walton, on April 14th, 1932. It was the first time that Einstein’s E=mc2 was verified directly in a nuclear reaction.
His and Cockcroft’s success, using artificially accelerated particles for experimenting on the atom, meant the research into the nature and structure of the atom was no longer restricted by having to rely on natural sources of radiation. In 1934, Walton returned to Trinity College, and was the Erasmus Smith’s Professor of Natural and Experimental Philosophy from 1946 until his retirement in 1974.

Ernest T.S. Walton generously presented his papers to the College Library in 1993; his family subsequently donated his Nobel medal. A small exhibition, which includes the medal, is currently on display in the Long Room, to mark the formal launch of the sculpture.
