The presentation gives a glimpse on the b road activities in the field of materials science and ion-track technology using swift heavy ions of GeV energy and above. The interest in such beam s is based on the large energy deposition along the trajectory of each ind ividual ion creating long nanoscopic trails of severe damage. In nanoscien ce\, the small track size in combination with the large ion range (up to 1 00 µm and more) allows us to overcome limits of planar structuring techni ques Several examples will be presented illustrating how to synthesize e.g . nanochannels and nanowires of tailored diameter\, length\, or shape with special electrical\, optical\, or thermal properties.\nIon beams at FAIR will permit materials science experiments with unprecedented ranges and in tensities. Injecting for instance relativistic ions through a mm-thick dia mond anvil of a high-pressure cell into a target under pressure\, drives t he local atomic structure far from equilibrium. Under such conditions\, st abilization of new materials was evidenced via pathways in the phase diagr am which are otherwise not accessible but of importance to simulate condit ions existing in the Earth mantle. Testing materials behavior in extreme r adiation\, pressure\, and temperature environments will also have a direct application to the understanding of structural materials degradation in n ext generation accelerator components\, fusion and fission reactors\, and shielding of equipment in deep space missions.\n\nReferences\n1.

DTSTART;VALUE=DATE-TIME:20181003T090000Z DTEND;VALUE=DATE-TIME:20181003T093000Z DTSTAMP;VALUE=DATE-TIME:20260510T084220Z UID:indico-contribution-4-231@luconf.lu.lv DESCRIPTION:Speakers: Marco Kirm (Institute of Physics\, University of Tar tu)\nLarge scale research facilities\, synchrotron radiation centres\, hav e played a crucial role in fundamental discoveries and in the development of novel functional materials. This is thanks to advancing experimental me thods based on superior radiation properties of storage ring based light s ources. Namely\, high brilliance of the radiation\, specific time structur e in ns-time domain and wide energy range from IR to hard X-rays are avail able for various experiments. In my talk\, I will focus on the materials r esearch carried out using time-resolved luminescence spectroscopy under VU V-XUV excitation at various research centres like DESY (Hamburg\, Germany) [1] and MAX-IV Lab (Lund\, Sweden) [2].\nSynchrotron radiation has been a n indispensable tool in the investigation of such short-wavelength emissio ns as cross-luminescence (CL) with ns decay and 5d-4f emission of rare ear th ions [3]. Recent advances in band structure calculations\, high demand on ultrafast scintillators for various applications and advancements of ph otodetectors (e.g.\, SiPM-s) with sensitivity shifted towards UV have rene wed interest to such ultrafast emitters. Multication fluorides with comple x band structure\, e.g.\, K2SiF6\, exhibit CL in UV-VUV and even visible r egions as shown by us using pulsed cathodoluminescence. The studies at sto rage rings can provide a deep insight into the relevant processes challeng ing for ultrafast scintillation applications. A particular topic of the sy nchrotron studies of wide band gap nanomaterials is aimed at understanding the influence of nano-particle size and morphology on the fundamental ele ctronic properties in comparison with bulk materials (see [4] for Al2O3). The peculiarities revealed via the excitation spectra of various intrinsic and extrinsic emissions in nano-alumina will be discussed. Finally\, rese arch challenges and experimental potential for luminescence spectroscopy a t the FinEstBeAMS of the MAX IV Lab will be reviewed. \n \nReferences\n1. G. Zimmerer. Rad.

However\, as strange as it may seem\, molecular aspects of organic nanophotonics are almost not considered in [1–4]. Consequently\, such important problems as molecule s and molecular complexes\, their structure\, light absorption and emissio n\, intermolecular charge and energy transfer in disordered organic functi onal layers\, and calculations of the corresponding parameters remained ou tside the scope of [1–4]. This lecture is specially devoted to theoretic al and computational aspects of these problems. Some of them were briefly considered in [5]. However\, the main focus in [5] was on the simulation o f nanophotonics structures. On the contrary\, this lecture is devoted to m odern quantum-chemical methods specially designed recently and currently u sed in the calculations of parameters required for the best description of excited states in organic molecules and in their intermolecular complexes (exciplexes)\, which are often characterized by significant intra- and in termolecular charge transfer. The set of these parameters include geometri cal (structural) parameters and energy data for ground and excited states\ , charge and energy transfer parameters\, light absorption and emission ch aracteristics\, and related properties. \nThis work was supported by the R ussian Science Foundation\, (project № 14-43-00052) and by the improving of the competitiveness program of National Research Nuclear University “MEPhI”.\n\nReferences\n1.

Evarestov ()\nMany practical applications of materials are based on the use of the properties caused by point defects\, in particular those induced by radiation. Theoretical modelin g of defective solids allows one not only explain existing experimental da ta but also predict the properties of new materials. For low defect con centration it becomes appropriate to model a single point defect in an en vironment of the remaining solid. In such a molecular cluster model th e crystal with a single point defect can be seen as a gigantic molecule an d the point defect properties are calculated using any of the methods of the molecular quantum chemistry. There are different possibilities to rep resent the rest of crystal: embedding into the crystalline environment (em bedded cluster model)\, saturation by additional atoms (saturated-cluster model). However\, in the case of a solid solution the single-defect model is not appropriate as the stoichiometry change is introduced by regular su bstitution of the host-crystal atoms by those of other chemical species. I n this case the point-defect models with periodic boundary conditions (cyc lic cluster and supercell) are more appropriate. These models allow one to use the computer codes and computational methods applied for both the perfect and defective crystals.\nThe symmetry aspects and applicatio ns of traditional supercell model of defective crystals are considered in [1\,2]. Recently a novel site symmetry approach for defective crystal c alculations in the supercell model was suggested [3]. It is based on the g roup-theoretical analysis of the site symmetry of the split Wyckoff positi ons in the perfect crystal supercell\, could be applied to a wide class of defects in crystalline solids and allows one to obtain more realistic values for the corresponding point defect formation energy. The efficien cy of site symmetry approach was demonstrated for copper impurity in LiC l crystal [2]\, carbon-doped ZnO crystal [4]\, oxygen interstitials in co rundum [5]\, polarons in cerium dioxide [6].\n\nReferences\n1.

In particular\, their anisotropic metallic-l ike electrical conductivity reaching values of up to 105 S/m at room tempe rature in combination with a poor thermal transport characteristic for wea k van-der-Waals bound crystals favor figures of merit\, zT = (σ S2/κ)T\, that are of technological relevance. By the correlated electron system an d its strong coupling to the surrounding lattice remarkable phenomena emer ge\, like phonon drag effects or the violation of the Wiedemann-Franz law\ , which support the implementation of organic conductors in future thermoe lectrics even further [1]. \nAfter introductory remarks on low-dimensional organic conductors and their correlated structural and electronic propert ies\, we will demonstrate by means of two representatives of this class\, the n-conducting DCNQI2Cu radical ion salt and the one-dimensional p-condu ctor TTT2I3\, the complex thermoelectric behavior as function of temperatu re (see Fig. 1) [2]. Based on this information and the interdependence of the relevant quantities an all-organic thermoelectric generator comprised of the two organic conductors will be presented as a proof-of-concept and compared in its performance with alternative approaches. Strategies to fur ther improve the thermoelectric performance of these low-dimensional organ ic conductors and their technological potential will be highlighted.\n\nRe ferences\n1. F.

Within the project duration\, the final CO 2EXIDE technology will undergo a thorough material and component R&D progr amme. A 1kW PEM electrolyser for CO22-reduction and water oxidation in com bination with an ethylene enrichment unit and subsequent chemical conversi on cascade reactor will be manufactured to produce ethylene oxide as inter mediate for oligo-/polyethylene glycol synthesis.\nFor example\, by using template-assisted electrodeposition it is possible to obtain hexagonally a rranged nanowire arrays with huge active surface for electrocatalysis. Usi ng e.g. 55 nm pore diameter alumina templates with 1 cm2 geometrical area to obtain 200 nm long nanowires it is possible to get material with estima ted 1357 m2 active lateral surface. This can be easily improved by increas ing the length of nanowires by introducing different shapes (periodically modulated or Y-branched) or by producing binary nanowires and etched on of components to obtain porous nanostructures.

Here we report on the use of X-ray absor ption near edge structure (XANES) spectroscopy and artificial neural netwo rk for refining the three-dimensional geometry of metal catalysts. Neural network is used to unravel the hidden relationship between the XANES featu res and catalyst geometry. To train the neural network\, we rely on the ab -initio XANES simulations by theoretical spectroscopy codes. Our approach allows one to solve the structure of a metal catalyst from its experimenta l XANES\, as demonstrated here by reconstructing the average size\, shape and morphology of well-defined mono- and bimetallic nanoparticles.1 In the case of ultra-small clusters their average size can be estimated. This me thod is applicable to the determination of the structure of metal catalyst s in operando studies and can be generalized to other nanoscale systems. I t also allows “on-the-fly” XANES analysis\, which is a required step f or high-throughput and time-dependent studies\, including the “reaction on demand” capabilities. \n\nA.I.F. acknowledges support of this work by the Division of Chemical Sciences\, Geosciences\, and Biosciences\, Offic e of Basic Energy Sciences of the U.S. Department of Energy through Grant DE-FG02- 03ER15476.\n\nReferences\n1 J.

Graphene in contact with oxides offers extremely high piezoelectric activity due to polarity of C-O bonds\, while peptide nanot ubes (PNTs) demonstrate excellent electromechanical properties due to self -assembly and intrinsic softness of directed hydrogen bonds. Remarkably st able structure\, possibility of functionalization together with biocompati bility and easy synthesis and nanofabrication\, make graphene\, PNTs and o ther biomolecular crystals (e.g. amino acid glycine [4]) attractive altern atives to traditional lead-based piezoelectrics. \nIn this presentation\, the mechanisms of piezoelectric effect in these structures will be delinea ted and methods for their studies will be introduced. Hybrid Piezoresponse Force Microscopy (Hybrid-PFM) will be presented allowing nanoscale electr omechanical measurements during acquisition of force-distance curves [6]. Several demonstrators including piezoelectric membranes based on 2D materi als (graphene)\, cantilevers based on PNTs\, and piezoelectric scaffolds f or cardiomyocite cells [7] will be presented. Recent results on piezoelect ricity and pyroelectricity in PNTs show that they are very attractive for various piezoelectric applications in biomedicine\, because of their intri nsic biocompatibility combined with mesoporous structure and ability to wo rk in contact with living cells and biological liquids. Scaling of piezoma terials down to nanosize is expected to dramatically improve their perform ance\, thus making nanoscale piezoelectrics more sensitive than the tradit ional ones. \n\n1.
