7^th Annual Congress on Materials Research and Technology February 20-21, 2017 Berlin, Germany (Golden Tulip Berlin Hotel Hamburg)

Denes Joo, after the Architecture and Urbanism University in Bucharest, studeed Mathematics-Mechanics, Economy, Sociology in Cluj-Napoca-city, and Postgradual Settlement and Regional Planning in Bucharest, and parallel with all these Physics, Chemistry, Astronomy and other scientific disciplines without limits (and titles). Elaborating new mathematical prognosis models, he extended the Futures-Research to the Systemic Evolutions Research, as a new synthesis in the science, extended it from the terrestrial to the cosmic evolution, from the micro- to the macro-world.

Extending the well-known periodic tables in both directions – micro and macro – in a new systemic evolutionary conception, by one side including the pre-elements Gluon and Quark, on the consideration of gravitation as criterion of the materiality, which is appearing on this level, by the other side continuing the periodic system, based on the alternative quaternionic model, with linear, stepped and spiral table components, results an arrangement of 560 elements in 76 periods (inclusive the „neutral gears”), organized in 7 cosmic steps, in correlation with the structure of our physical Universe. Because in reality the particles are wave-agglomerations in some wave/energy fields, the question is, to which field belong the respective particles? Therefore, above all it needs to clarify the fields. The classical field-theories refer especially to the electric and gravific fields, touring the scalar-vector-tensor complexity of the mathematical-physical quantities, but – precluding the possibility of the ETHER – the explanations referring to the physical phenomena are incomplete or/and inadequate to the reality. While the Platonic solids are Ether-patterns, the plane – (ring-horn-spindle) torus – sphere pulsation models the functioning of the Universe on every fractal level. In the case of the horn-torus (R=r), which includs an infinitesimal/elemental cone, results a conic-toroidal structure, of which elements represent the three basic cosmic fields, with their complementary fields together (conics and belonging Dandelin-spheres): HYPERBOLA: thermo-gravific field, with gravific monopols; PARABOLA: electro-magnetic field, with magnetic monopole; ELLIPSE: ethero-quark-gluonic field, with quark-gluonic dipole. The corresponding macro-cosmic structure is detailed in the Toroidal-hexagonal structure on Macro-cosmic level.

Ms Edhaim has been enrolled as a PhD student in the KAUST chemistry program since the beginning of 2013. She has completed the master portion with 36 credits. Since she joined KAUST, she adapted quickly to the academic working environment, progressed very well and has expanded her technical skills. \r\nIn the laboratory Ms Edhaim synthesizes new porous materials, which have promising applications in gas and hydrocarbon separation. She participated in a number of international conferences where her work was selected for oral and poster presentations and where she received very good feedback from colleagues. At present Ms Edhaim is publishing her papers with results for at least three research articles. \r\nMs Edhaim is an expert user of many analytical techniques incl. XRD, XRF, SEM, EDX, TGA, TDA, ICP, CPD, FTIR, UV and physical adsorption instrumentation.\r\n

The synthesis and characterization of the rare earth chalcogenide aerogels NaYSnS4, NaGdSnS4 and NaTbSnS4 is reported. Rare earth metal ions like Y3+ , Gd3+ and Tb3+ react with the chalcogenide clusters [SnS4]4- in aqueous formamide solution forming extended polymeric networks by gelation. Aerogels obtained after supercritical drying have BET surface areas of 649 m2/g (NaYSnS4), 479 m2/g (NaGdSnS4) and 354 m2/g (NaTbSnS4). Electron microscopy and physisorption studies revealed that the new materials have pores in the macro (above 50 nm), meso (2-50 nm) and micro (below 2 nm) regions. These aerogels show higher adsorption of toluene vapor over cyclohexane vapor and CO2 over CH4 or H2. The notable adsorption capacity for toluene (NaYSnS4: 6.90 mmol/g), (NaGdSnS4: 12.36 mmol/g) and (NaTbSnS4: 9.76 mmol/g) and high selectivity for gases NaYSnS4 (CO2/H2: 155 and CO2/CH4: 37), NaGdSnS4 (CO2/H2: 172 and CO2/CH4: 50) and NaTbSnS4 (CO2/H2: 75 and CO2/CH4: 28) indicate potential future use of chalcogels in absorption-based gas or hydrocarbon separation processes.
