This newsletter consists of a combination of articles, highlighting both recent professional successes and iMagiMat takes centre stage at the Conservative Conference and wins award An innovative new device being developed by Krikor Ozanyan and Patricia Scully from the PSI and their fellow researchers from Engineering and Nursing was exhibited in the Innovation Zone at the Conservative party conference in October 2013. The exhibits were visited by Prime Minister David Cameron, Foreign Secretary William Hague and Health Secretary Jeremy Hunt, as well as hundreds of conference delegates. The iMagiMat is almost indistinguishable from a regular carpet but can prevent falls in the elderly iMagiMat, also known as ‘the magic carpet’, is an intelligent mat made up of plastic optical fibres, laid on the underlay of a carpet. Conference-goers can see how the optical fibres can bend when they tread on it and map in real-time their walking patterns. iMagiMat maps 2D images by using light propagating in fibres under the surface of the smart carpet. Compact electronics at the edges measure and relay sensor signals to a computer. The signals are analysed to show the footprint image and identify gradual changes in walking, or a sudden incident such as a trip or fall, so a potential use for the carpet could be in nursing and care homes. The iMagiMat was nominated for the BioNow Innovative Aging award, and was listed as runner up in November 2013. The team includes Krikor Ozanyan, Paul Wright and Jose Cantoral Ceballos (EEE), Patricia Scully (CEAS) and Christine Brown Wilson and Chris Todd (NMSW). Dr Patricia Scully (CEAS) and Dr Jose Cantoral Ceballos (EEE) attended the awarded dinner on Thursday 28 November together with Daniel Syder of UMIP to represent the team. those of a personal nature. Please send any items you have either for The Photon Science Institute website or the next newsletter to PSIPA@manchester.ac.uk Jose Cantoral Ceballos and Patricia Scully at Bionow Awards Dinner, where the iMagiMat won the runnerup prize P age 2 P S I New sl etter S p ri n g 2 01 4 A Message from the Director Welcome to 2014. This promises to be an exciting and hectic year for the PSI. The main change that we are all going to notice very soon is the arrival of the £18M Multidisciplinary Characterisation Facility (MCF), accompanied by other equipment funded by EPSRC to around £6M. Laboratory reorganisation The building work to accommodate the MCF will start in the middle of March. There will be disruption on the ground floor, with the entrance to the building opposite to the entrance to the Alan Turing building sealed off for a period of months. The groups within the large ground floor laboratory will also have to perform a courtly dance to relocate the EPR facility in the area at the west end of the building, with Professor Andrew Murray’s experiments moving to the area currently occupied by the EPR facility. On the third floor we will lose the seminar room and kitchen for a few months while the expansion space is transformed and then occupied by the Henry Moseley X-ray Imaging Facility. It will be an excellent addition to have these very energetic photons joining the Institute, and I believe there will be outstanding opportunities to develop new experiments by combining our existing strengths with those of our colleagues from the School of Materials. The MCF will also involve work on the 2nd floor. A new environmental XPS will arrive and occupy half of a laboratory on the 2nd floor. New and existing Raman equipment will be added to our Raman facility, again bringing new colleagues from Materials into the PSI community. This later move will involve relocating one of Professor Bruce Hamilton’s experiments. Some other moves have already taken place. We welcome BGT Materials (Drs Amanda Lewis, Liam Britnell and Thanasis Georgiiou have already moved in); they are building a graphene production facility in laboratory 2.308, and as they establish their European operation in Manchester their office area will expand. This will require that the Electronics Workshop relocate to the Mechanical Workshop. This move should take place in late February or March. Future I have now been Director for almost five years, and it is time for a change. The PSI has been transformed in five years, with a huge range of new experiments moving in, beginning with the National EPR Facility and Service, through to the MCF. We will be jointly hosting a MarieCurie training site (with MIB) from September. New activity probably represents something like £40M of new experiments. We have excellent new research fellows who have arrived since me, in Darren Graham, Alistair Fielding, Publications with PSI address Fig 1.

S p ri n g 2 01 4 Director, but leadership from all academic staff, both acting individually and working as a team. We contribute Our publication performance has also improved powerfully to major initiatives, and some of us lead such dramatically. We are now publishing around 90 papers a initiatives, for example Bruce Hamilton has led university year, and in 2013 our work was cited > 1100 times: efforts in developing new initiative in medical sensors, This appears to be a strong position, however the and Mark Dickinson is working very hard on microscopy. citation performance remains patchy. Most of our Academic research goes in cycles, and the current cycle citations are for Raman spectroscopy of graphene, or favours large-scale activities over small research groups. the molecular magnetism and EPR group. Similarly our Therefore research leadership is going to be essential as papers in Science and the Nature group are based on the PSI changes and continues to thrive. We have the these activities. We need more groups to be performing capability to deliver leadership in photon science to the to this level for the PSI to be a success. Citation University of Manchester, and probably on a broader performance is not everything, but it is an objective stage, but we have not yet proven this assertion. Such indicator and therefore far more valuable than subjective leadership is hugely time-consuming but the rewards are opinion as a measure of how well we are doing. We great. And given the remit of the PSI – to be a worldcannot ignore objective data and still claim to be leading institute in photon science – scientists. Everyone should be trying to publish in the such leadership has to be part of our very best journals in their field. Submitting to the best activity. journals will increase your rejection rates, but revising a paper for a second journal really doesn’t take very long. If you are trying the correct journals, about one in three Richard Winpenny of your papers should be rejected on first submission. As the PSI moves forward leadership is going to be vital. This isn’t merely the question of appointing a new New “Fielding group” in EPR A new EPR group is up and running, based within the EPSRC National EPR Research Facility and Service. The group specializes in solving biological problems and has students based in both the Manchester Institute of Biotechnology and the Michael Smith Building. Given the prime location we also have a number of PSI collaborations concerning materials science based projects.

P age 4 P S I New sl etter S p ri n g 2 01 4 University of Manchester researchers fly the flag in Boston Dr Iain Crowe was selected to visit the Massachusetts Institute of Technology (MIT) in Boston (one of the world's top universities) as part of the M2EET MAHSC-MIT initiative in December 2013. Other researchers from the University came from the Medical and Human Sciences, Life Sciences and the Engineering and Physical Sciences faculties. The purpose of this initiative was to facilitate the exchanging of ideas, expertise and interests to enhance opportunity for cross-disciplinary collaboration with the ultimate goal being to facilitate development of young investigators and create sustainable, mutually beneficial, cross-disciplinary collaborative partnership between Manchester and MIT. Longer term, M2EET will act as a vehicle for leverage of external investment for new crossdisciplinary collaborative projects. The initial plan for the exchange is to enable 10 junior faculty (from clinical, life sciences, engineering) selected throughout the MAHSC partner organisations to develop connections with MIT. These new connections were celebrated over the two-day meeting in Boston on 4th/5th December. As a result of Iain’s trip to Boston, he is now developing a collaboration with a group at MIT in photonic materials for CMOS integrated light sources and bio-sensing applications, which he hopes will lead to high impact publications and joint bids for funding in the near future. You can read more about the initiative here: http://www.trustech.org.uk/news/m2eet/. Meet the new PSI Fellow By Ahsan Nazir My research interests are based around understanding the delicate interplay of quantum coherence and noise in open quantum systems. I have developed a number of innovative methods to model open quantum systems beyond common approximations, and applied them in diverse areas ranging from solid-state quantum information processing to quantum biology. By building on the idea of redrawing the boundary between system and environment, I now aim to develop an efficient framework in which to study both the equilibrium and non-equilibrium dynamics of many-body open quantum systems, beyond perturbative regimes. I shall use this approach to explore a number of important problems in the context of light-matter interactions in solid-state and biomolecular systems, such as robust quantum state generation, biomolecular energy transport, and solar energy conversion. The PSI offers an unprecedented opportunity for me to develop my research alongside scientists at the top of their fields in a wholly multidisciplinary environment, and I am very much looking forward to becoming an active member.

Visible wavelength photon correlation spectroscopy (PCS) is a standard tool in photon science laboratories all over the world. However, many conventional PCS measurements are obstructed by sample opacity (a slight cloudiness of specimens can lead to artefacts due to multiple scattering) and are only sensitive to relatively large length scales (set by the diffraction limit). X-ray PCS methods neatly circumvent these two problems, since most materials are fairly transparent to X-rays and their decreased wavelength (~0.15 nm versus ~500 nm) gives improved sensitivity to smaller length scales. As a result XPCS provides access to time scales and length scales that are not easily probed by any other form of spectroscopy (~ms-1000s, ~1-1000 nm). 1.1 1 -2 10 -1 10 0 10 t [s] 1 10 2 10 -2 10 -1 10 0 10 t [s] 1 10 2 Initial experiments have probed the dynamics of soft condensed matter systems (colloids in glycerol), but a wide range of samples can in principle be explored. Please contact Tom Waigh (t.a.waigh@manchester.ac.uk) or the synchrotron directly if you have a nanostructured fluid and would like to explore its dynamics.

The sample to detector distance was 18 m. The XPCSGUI software correlator was a gift from Michael Sprung (DESY). P age 6 P S I New sl etter S p ri n g 2 01 4 Joint São Paulo - Campinas - Manchester collaboration-building workshop By Wendy Flavell Some of the workshop delegates; in the front row (L-R) are Antonio Domingues dos Santos (USP, in the white shirt), Rene Nome (UNICAMP), Romulo Ando (USP), Koiti Araki (USP), Wendy Flavell (UoM), Hermi Brito (USP), Pedro Camargo (USP), Marina Leontiadou (UoM) and Sarah Haigh (UoM). The PSI recently hosted a party of Brazilian visitors from University of São Paulo (USP) and the State University of Campinas (UNICAMP) for an interdisciplinary collaboration-building workshop, attended by around 45 delegates. The three-day event at the end of January, took place in PSI and MIB (the Manchester Institute of Biotechnology), and was supported by EPS Faculty and the PSI. The meeting focused on charge and energy transfer at surfaces, and was organised by Wendy Flavell - with a great deal of help from Cassandra Kenny, Dave Binks and Pedro Camargo (USP). Our guests gave up part of their summer holidays, braving appalling weather in Manchester (and a temperature difference of around 32°C) to contribute to the meeting. We had some fantastically-productive research discussions, so expect to see more news about Brazil soon.... but we think we might hold the next conference somewhere warmer perhaps, Pedro?

ISBN: 978-0-444-62644-8. A second article of theirs was published in High Pressure Research on high pressure studies of carbon nanotubes with their collaborators at Queen Mary University, London. DOI: 10.1080/08957959.2013.878714 They also had a journal article published by the Journal of Applied Physics, describing the probing of optically active Sm dopants in TiO2 using X-ray techniques, which was carried out as part of a collaboration with colleagues from Japan (NIMS and U of Tokyo) and Canada (Canadian Light Source (synchrotron facility) and UWO), and colleagues Bruce Hamilton and Masashi Ishii. DOI: 10.1063/1.4824375. Just recently, the same researchers have had a paper published in the Japanese Journal of Applied Physics, about non-radiative recombination in Er doped Si nano-crystals during thermal quenching of intra-4f luminescence. DOI: 10.7567/JJAP.53.031302 David Binks has had two papers published recently. “Multiple exciton generation and ultrafast exciton dynamics in HgTe colloidal quantum dots” by Ali Al-Otaify, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach, Guy Allan, Christophe Delerue and David J. Binks (Phys. Chem. Chem. Phys., 2013,15, 16864-16873) (DOI: 10.1039/ c3cp52574k) and also “Comparison of Solar Cells Sensitised by CdTe/CdSe and CdSe/CdTe Core/Shell Colloidal Quantum Dots with and without a CdS outer layer” by N. McElroy, R. Page, D. Espinobarro-Velasquez, E. Lewis, S. Haigh, P. O’Brien and D. J. Binks. (Thin Solid Films - in press.) Mark Jackman (a NowNano PhD student) and Andrew Thomas have published an experiment important to the development of dye-sensitised solar cells. The paper reports on work carried out on beam line D1011 at Maxlab on the effects of illumination of a di-substituted aromatic molecule with ultraviolet and visible radiation and proposes a mechanism for the photocatalytic degradation of the molecule. It also addresses the adsorption mode of the molecule, in particular clarifying the nature of the amine-TiO2 surface bond proposed in earlier work for aniline adsorption on this surface. Mark J. Jackman and Andrew G. Thomas, J. Phys. Chem. C., in press. DOI: 10.1021/jp4103405 Patricia Scully and her colleagues at the University of Liverpool had had a paper published in Laser Physics Journal, entitled: “NUV femtosecond laser inscription of volume Bragg gratings in poly (methyl) methacrylate with linear and circular polarizations”. This paper explains how a spatial light modulator can be used to control the laser inscription of photonic structures into transparent optical materials, in this case, polymers, and demonstrates that several beams in parallel can be used to speed up the process. The work results from a 10 year collaboration with Dr Walter Perrie, Senior Research Fellow at the Lairdside Laser Engineering Centre at The University of Liverpool.
