"Light - Lamps - Luminescence - from basic research to applications"

Claudia Wickleder
School of Science and Technology University of Siegen,
Germany

Abstract
The development of new optical materials is currently a hot topic also with respect of energy saving purposes. In fact this is shown by the drastic change in lightening techniques in Europe, changing from incandescent lamps over discharge lamps to modern LEDs, which energy balance is improved compared to former lamps. However, the development of suitable materials for these applications is necessary. In this presentation, promising candidates in this context with very high efficiencies, suitable emission energies and low excitation energies, which are crucial for energy saving will be introduced. Furthermore, some respective nanoparticles will be presented which are useful for applications as medical markers or to investigate the toxicity of nanoparticles.

"Adsorption and magnetic filtration of pollutants by a biochar-based composite"

Abstract
Biochar, defined as the carbon residue obtained from the thermal decomposition of biomass, can be used for a wide variety of applications, such as soil amendment, adsorption for water and air pollutants, catalysis, electronic industry or hydrogen storage. For the removal of pollutants from water, the association of biochar with magnetic particles inside a composite material enables the sorbent to be easily separated by magnetic filtration from the decontaminated water after the adsorption step [1]. In this work, the chemical and physical properties of a magnetic biochar obtained from a biorefinery residue have been investigated, with the association of a classical sorption study to a physical study for the understanding and optimization of the magnetic separation.

"Specific mechanisms associated with rare earth dopants (Yb, Er, Ce) in the radiation induced attenuation of silica based optical fibers"

Franck Mady
Université Côte d'Azur, INФNI, Laboratoire de Radieochimie,
Sciences Analytiques et Environnement (LRSAE),
Parc Valrose 06108 Nice, Cedex 2,
France

Abstract
We report on an original approach enabling an in depth investigation of the mechanisms of the radiation induced attenuation (RIA) development and annealing in silica based fiber preforms [1]. The experim ental protocol combines temperature and spectrally resolved TSL measurements with the characterization of the RIA annealing in TSL conditions. TSL allows the identification of those dopant or defect related centers that trap free carriers under irradiati on to form color centers (responsible for RIA) and that are restored by recombination during the thermal annealing induced by the TSL readout. The simultaneous monitoring of the RIA bleaching reveals correlations between these reformation processes and the recovery of radiation induced optical absorption bands attributed to well known color centers. Such correlations bring decisive indications on RIA mechanisms.
Our protocol is applied in a systematic manner to silicate, aluminosilicate, Yb doped silicate, Er doped silicate, Yb doped and Yb,Ce codoped aluminosilicate preform samples to elucidate the role played by each dopant.

"Computational Photonics and Topological Materials"

Alexander Quandt
University of the Witwatersrand,
WITS University 1 Jan Smuts Avenue Braamfontein 2000,
Johannesburg,
South Africa

Abstract
In recent years it became clear that many photonic structures show interesting topological properties, which had simply been overlooked in the past. I will give an introduction into this fascinating topic and discuss various examples like topological photonic crystals and topological waveguide arrays. My focus will be on an elementar y discussion of the main results, where I will slightly deviate from the standard approaches and show how to apply rather intuitive concepts like the Brouwer degree, instead of falling back on more abstract mathematical concepts. Finally, I will discuss so me of the numerical approaches used to study topological photonic systems.

"Light scattering in nanoparticles doped optical fibers, an opportunity"

France

Abstract
Distributed sensing, based on Rayleigh scattering or arrays of reflectors, can be extended as a multi-fiber, multi-sensor technique by using multiplexing features. Current research has overcome the time-and wavelength-division multiplexing, that has represented the golden standard for fiber Bragg gratings. During this presentation, we introduce a novel domain that allows “parallel” multiplexing applied to distributed sensors, and are routed in the use of specialty fibers. The use of nanoparticles doped optical fibers enables new domains for multiplexing, that are discussed during this presentation. Scattering-level, polarization, and sensitivity-based multiplexing are discussed and applied to strain, temperature, 3D-shape and refractive index measurements.

France

Abstract
The successes of glass photonics are many, with a large spectrum of applications covering Information and Communication Technology, Health and Biology, Structural Engineering, and Environment Monitoring Systems, etc. A paradigmatic example is the development of the Erbium-Doped Fiber Amplifier (EDFA) allowing the raise of optical telecommunications and high-speed internet. Silica glass is the most common glass used for photonics applications. However, certain of its characteristics may be detrimental for luminescence properties (low rare-earth solubility, high phonon energy, etc). To overcome these limitations, the use of nanoparticles in optical waveguides is gaining large interest in modern photonic technology. Such waveguides would combine the advantages of silica (transparency, cost, chemical and mechanical durability, etc.) and the specific properties provided by the nanoparticles which encapsulate the rare-earth ions. During this presentation, we will discuss on the opportunities offer for lasers and amplifiers thanks to the engineering of the spectroscopic properties and the management of nanoparticlesinduced light scattering.

Spaventapasseri fotonico e spaventapasseri ontologico
Usare la luce per la protezione delle colture

I ricercatori trentini di IFN e ISTC, istituti del CNR (https://www.cnr.it), presentano alcuni dispositivi ottici ed un prototipo compatto e maneggevole che utilizza la luce per spaventare gli uccelli senza l'uso di sostanze chimiche e con basso uso di energia. In parallelo il pubblico potrà confrontarsi con una analisi concettuale di come si concepisce e modella il mondo con e in questi sistemi.

L’evento “Stand hands-on” si terrà presso il MUSE nel quartiere Le Albere a Trento venerdì 27 settembre 2019 dalle 17:00 alle 24:00 nell’ambito delle attività organizzate da FBK, MUSE, FEM e UNITN, con la collaborazione della Provincia Autonoma di Trento in occasione della Notte dei Ricercatori.

September 19th-20th, 2019
University of Silesia in Katowice, Chorzow (Poland)

Dear Colleagues,

On the behalf of the Graduate Student Government of the Faculty of Mathematics, Physics and Chemistry at the University of Silesia in Katowice (Poland), we would like to invite all early-stage scientists - students, Ph.D. candidates as well as young researchers - to attend in the 8th edition of the interdisciplinary conference SCIENCE BEYOND DISCIPLINES. Initially, the conference was structured around three main scientific pillars – chemistry, physics and biology - however, the upcoming edition will target also the field of engineering and technology, as well as medical sciences. Our main intention is to provide an opportunity for an interdisciplinary dialogue that will contribute to increasing scientific knowledge through the exchange of ideas with not necessarily like-minded researchers, promote the innovation and risk-taking in science, as well as encourage collaboration among the participants at international level.

The conference will be held in Chorzow (Poland) on September 19th-20th, 2019. The registration for the active participants is open until the July 28th, while for the passive attendees until September 7th. We are also proud to announce that all of our invited speakers have been already confirmed - Prof. Wiesław I. Gruszecki (Maria Curie-Sklodowska University, Lublin, Poland), Dr. Sergey Yatsunenko (NOVISMO: http://novismo.com/?lang=en) and Prof. Chris Hardacre (University of Manchester, UK).

All the necessary information can be found on our official website https://www.pomiedzynaukami.us.edu.pl/index.php/en/home and Facebook profile https://www.facebook.com/sciencebeyonddisciplines/. You can also contact us at us.konferencja@gmail.com.

You are cordially invited to visit Poland and participate in the Science Beyond Disciplines 2019!

See you in September!
