Fundamentals of climate change physics and how they imply the Paris climate goals
Gottfried Kirchengast, Wegener Center for Climate and Global Change

The physical science basis underpins all of climate change science and societal implications, including the impacts of global warming and related natural and socio-economic changes. The latter include critical threats such as losses and damages, the need for adapting to unavoidab ... more

Stimuli Responsive Hydrogels via initiated Chemical Vapor Deposition
Katrin Unger, Institute of Solid State Physics, TU Graz

Chemical modification of polymer materials can be used to synthesize smart hydrogels that respond to one or more stimuli. In details, responsiveness to exposure to humidity or aqueous environment, light irradiation and the pH-value is used to tune the mechanical and electrical pr ... more

Alloying and structural rearrangements in Fe-Au, Co-Au and Ni-Au core- shell nanoparticles
Martin Schnedlitz, Institute of Experimental Physics, TU Graz

Bimetallic nanoparticles formed by a combination of magnetic and noble metals have recently received increased attention as the combination of inter-metallic interactions and surface size effects can trigger unexpected physical behaviour and new phenomena. Understanding the featu ... more

New synthesis of Vanadium oxide cluster
Maximilian Lasserus, Institute of Experimental Physics, TU Graz

We present a new approach for the synthesis of neutral V2O5 nanoparticles. This is achieved by sublimation from bulk, in combination with a pickup by superfluid helium droplets. Time-of-Flight mass spectroscopy measurements clearly demonstrates the preservation of the bulk stoich ... more

Impact of collective electrostatic effects on core-level excitations
Thomas Taucher, Institute of Solid State Physics, TU Graz

Investigating the influence of collective electrostatic effects is of vital importance when studying hybrid organic-inorganic systems. These are especially crucial when dealing with organic self-assembled monolayers on metal substrates.[1] In this contribution we discuss the appl ... more

13:30 - 14:00

Why is electronic transport in conjugated organic materials rather inefficient?
Christian Winkler, Institute of Solid State Physics, TU Graz

Already several years ago it has been shown that for molecular dimers the electronic coupling between neighboring molecules strongly depends on their relative arrangement.[1,2] When considering semiconducting molecular crystals this relative arrangement of neighboring molecules t ... more

14:00 - 14:30

Surface tension and density measurement of liquid industrial steels and alloys by means of the oscillating drop method using an electromagnetic levitation apparatus
Thomas Leitner, Institute of Experimental Physics, TU Graz

The temperature dependent surface tension and density of liquid steels and alloys are two thermophysical properties that are of great interest for a large variety of industrial applications but also in fundamental research and space science. Since in today’s metalworking indust ... more

Thermophysical property measurements of standard materials and industrial steels: On the ground and on board of parabolic flights
Peter Pichler, Institute of Experimental Physics, TU Graz

Knowledge of thermophysical properties of complex alloys like industrial steels are of fundamental importance in our daily world. Airplane turbine blades, car engines or parts of nuclear reactors are only some of the products that are dependent on computational simulations and mo ... more

µ-mixer & µDrop for SAXS - Two new instruments for microfluidic sample processing
Richard Haider

Two new instruments have been developed at and for the use at the Austrian SAXS beamline at the Elettra-Sincrotrone in Trieste, Italy. This beamline is an outpost of the TU Graz for synchrotron based Small Angle X-Ray Scattering (SAXS), which is a widely used technique for invest ... more

Microstructured P(VDF-TrFE) Featuring Embedded Electrodes for Flexible Direction-Sensitive Strain Sensors and Micro-Harvesters
Philipp Schäffner, Joanneum Research Forschungsgesellschaft mbH, MATERIALS Institute, Weiz

Tomorrow’s Industry 4.0 environments raise a growing demand in self-sustained, flexible and low-cost sensors for versatile applications in process control as well as condition and energy monitoring. The printable ferroelectric copolymer poly(vinylidene-trifluoroethylene) (P(VDF ... more
