New funding for doctoral school TU-D

Graphene is the most famous 2D-material.

2022-Dec-02

The Austrian Science Fund FWF has officially accepted the proposal TU-D, co-authored by Ulrike Diebold and Gareth Parkinson. The FWF will continue to fund an interdisciplinary doctoral school with 2 mio. € at the TU Wien, which focuses on so-called two-dimensional materials - compounds which consist of a single atomic layer and bear immense potential for various technical applications. It is part of the FWF program doc.funds, coordinated by Florian Libisch from the TU Wien.


Nanopore Formation in 2D materials

The authors of the TU Wien study: from left to right: Friedrich Aumayr, Christoph Lemell, Anna Niggas, Alexander Sagar Grossek, Richard A. Wilhelm 2022-Nov-28

* When charged particles are shot through ultra-thin layers of material, sometimes spectacular micro-explosions occur, sometimes the material remains almost intact. In a collaboration of the Atomic and Plasma Physics Research Unit of IAP with Christoph Lemell, Professor at the Institute for Theoretical Physics of TU Wien, it has now been explained in which situations holes are formed and in which they are not - and that this depends on the electron mobility in the material and the charge state of the projectile. The results have been published in “Nano Letters”.

The theory of micro-hairs

2022-Nov-09

Our lungs, brains, and reproductive organs depend on the coordinated motion of hundreds of thousands whip like cellular appendages, so called cilia, that collectively drive fluid and keep their surfaces clean and functioning. For this to work cilia need to synchronize their motions over length scales that order of magnitudes bigger than the individual cilium. In their paper, published in PNAS, scientist from the Theory of Living Matter Group (headed by Sebastian Fürthauer from the Biophysics Research Unit at IAP, TU Wien), and the University of Southern California, show how cilia can synchronize through fluid mediated interactions alone and self-organize into metachronal waves that efficiently pump fluid along ciliated surfaces. They further provide a theoretical framework, which enables the study of ciliated surfaces in the context of a continuum theory. This advance will enable the systematic numerical study of large and geometrically complex ciliated structures, such as our organs, which had been prohibitively expensive with previously available methods.

Nuclear fusion: A new solution for the instability problem

Aumayr fusion research group at TU Wien

For fusion reactors like ITER, plasma instabilities are a major challenge. By experiments carried aout at the Max Planck Institute for Plasma Physics in Garching, Georg Harrer and other members of the Atomic and Plasma Physics Research Unit of IAP could now demonstrate: There is an operational regime for fusion reactors which avoids this problem. Instead of large potentially destructive instabilities, one intentionally accepts many small instabilities that do not pose a problem for the reactor’s walls. The results have now been published in the journal as Editors' Suggestion and featured in physics.

Studying ultrafast charge dynamics upon ion impact

Ion physics on the fs scale 2022-Aug-22

* When ions penetrate a material, highly complex processes take place - so fast that they could hardly be studied until now. A team from the Atomic and Plasma Physics Research Unit of IAP in collaboration with colleagues from Uni Wien, Germany (Kiel, Dresden, Jena) and Ireland (Dublin) has now succeeded in analyzing on a time scale of one femtosecond what happens to the individual particles involved, when an ion penetrates 2 dimensional materials such as graphene or molybdenum disulphide. A careful analysis of the electrons that are emitted in the process allows to reconstruct the temporal sequence of the processes. The results have been published in “Physical Review Letters” and selected as “Editors' Suggestion”.

Nanoparticles can Save Historic Buildings

Nanoparticles can Save Historic Buildings like St.. Stephans Cathedrale in Vienna

2022-Jul-10

Buildings made of porous rock can weather over the years. Now, for the first time, Markus Valtiner and his Applied Interface Physics Research Unit have studied in detail how silicate nanoparticles can help save them. Together with colleagues from the University of Oslo his group has now been able to clarify exactly how this artificial hardening process takes place through elaborate experiments at the DESY synchrotron in Hamburg and with microscopic examinations in Vienna. That way, the team could determine which nanoparticles are best suited for this purpose.

Single atoms, or dimers?

Pt dimers are actually responsible for CO oxidation in what is nominally a single-atom catalyst

2022-April-4

So called “single-atom” catlysis is all the rage in catalysis research - a team from the surface physics group at IAP together with theorist colleagues from The University of Vienna have shown that metastable Pt dimers form when the single Pt atoms are exposed to CO, and that these are really responsible for the CO oxidation activity observed. The paper appeared in the journal Science Advances.

2021-Sep-20

Beams of energetic ions are used to clean or nanostructure various materials via sputtering. Christian Cupak and his collborators from the Atomic and Plasma Physics Group of IAP have now been able to explain how the sputtering process depends on the roughness of the surface. Using experiments and simulations they were able to show that the mean inclination angle of the surface (accessibly e.g. by atomic force microscopy or other high resolution microscopy methods) describes the final outcome of the sputtering process much better than other roughness parameters that have been used so far.

2021-Aug-16

What happens when ions are passing through solid materials? It is nearly impossible to observe this directly, but the Atomic and Plasma Physics Group of IAP has found a way to overcome this problem. By peeling graphite layer by layer Anna Niggas and her collaborators uncovered how ions recapture their electrons when moving through solid material. The new measurements show that the ions obey remarkably simple laws.

Laboratory experiments could unravel the mystery of the Mars moon Phobos

The planet Mars with its moons Phobos and Deimos

2020-Nov-30

What causes the “space weathering” on the Mars moon Phobos? Results of laboratory experiments performed by Paul Szabo and collaborators in the Atomic and Plasma Physics group of IAP give new insights and show that beside the solar wind also the irradiation by particles from Mars plays a decisive role there. These considerations could soon play an important role in the evaluation of real Phobos samples since in 2024 a Japanese space mission will take soil samples from Phobos and bring them back to Earth. The work is part of an international FWF-SNF project together with the University of Bern.

When human and computer agree

The unexpected surface structure of IrO2 2020-Oct-13

Iridium oxide is an excellent catalyst for electrochemical reactions, and used for the production of hydrogen from water by electrolysis. Members of the IAP surface physics group and the Technical University of Munich have discovered that its surfaces – where catalysis happens – are quite different from what scientists have previously thought. The atoms in the near-surface layers rearrange, stabilizing otherwise unfavorable surface orientations. These structures have been found by machine learning and perfectly agree with experimental findings. The results are published in Physical Review Letters.

Nanocarving with highly charged ions

ACS Nano

2020-July-31

Carving well-defined holes into a stack of 2D materials is not an easy task, especially if only one atomic layer shall be modified not harming any material underneath. With slow highly charged ions the Atomic and Plasma Physics group was able to achieve this ultimate surface sensitivity by developing a technique for processing novel 2D-materials on an atomic scale. Their most recent work on nanostructuring of freestanding MoS2/graphene heterostructures with highly charged ions was just published by ACS Nano. The fruitful collaboration with the group of Jani Kotakoski (University Vienna) made sample preparation as well as exceptional quality microscopy available. The experiments demonstrated that one can remove the very first monolayer of these structures on a tiny area of only a few square-nanometers.

The results not only show that the ion’s potential energy is deposited in the topmost surface layer, but also that the energy remains in that particular layer. Interesting applications are just ahead!

Molecules: How to be Gentle

Oxygen configurations on TiO<sub>2</sub> and Martin Setvin (l) and Igor Sokolovic in the lab 2020-June-09

For some molecules it is quite challenging to take images without altering them. O2, for example, dissociates into two atoms when hit with the electrons that are used in traditional imaging techniques that provide the necessary resolution. Using non-contact AFM with and a tip with one single oxygen atom at the very end, the surface physics group has managed to provide undisturbed images of O2 adsorbed on TiO2. This system has been investigated by many research groups throughout the years, and the new images have resolved several mysteries. The results were published in the journal PNAS.

Slow electrons for cancer treatment

Janine Schwestka

2019-Aug-19

Ion beam radiation therapy uses complicated atomic-physical effects to fight cancer cells. Janine Schwestka and co-workers have now identified a new mechanism that directly emitts low energy electrons, which are very effective in destroying cancer cells. An effect that has received little attention in this context plays an important role, the so-called “Interatomic Coulomb Decay” (ICD). The result has now been published in the Journal of Physical Chemistry Letters.

The Importance of Trace Impurities and how to Avoid them

2018-Aug-24 The cleanest water drop comes from an icicle

  • Titanium dioxide (TiO2) is highly versatile material, used, e.g., for self-cleaning mirrors. When bringing one of its surfaces in contact with water, researchers around the world have observed a structure that was interpreted as ordering of water molecules or caused by carbon dioxide dissolved in the water. Jan Balajka and colleagues of the IAP surface physics group, together with Melissa Hines (Cornell University) could disprove these ideas. They have used what is probably the purest water drop on Earth, created from an icicle in ultrahigh vacuum (see photo). Surprisingly, the TiO2 surface structures turned out to come from trace impurities in the atmosphere such as formic acid, present in concentrations of only 1:1000000000! These results were published in the prestigeous journal Science.

Immune system: T-cells are designed for speed

2018-July-17 T-cell study

  • T cells, a key component of our immune system, detect smallest amounts of bacterial or viral portions with their T cell receptor (TCR) and serve as an important proponent of the defence mechanism. One explanation, why T cells are super-sensitive is that the TCRs are concentrated at certain areas on the membrane of T cells. Our group, in collaboration with the Medical University of Vienna and the Max Planck Institute of Biophysical Chemistry in Göttingen, could show that TCRs are actually distributed randomly on the cellular membrane of resting T cells and not concentrated in nano-clusters as believed earlier. This study has now been published in Nature Immunology.

The true power of the solar wind

Solar Wind

2018-Jun-12

  • The solar wind, a steady stream of mainly protons and few multiply charged heavier ions from the sun, causes significant erosion upon impact on the surface of atmosphere-less planets like Mercury or on the moon. In a recent paper Paul Szabo and co-workers now show that previous models of this process are incomplete. The effects of solar wind bombardment are in some cases much more drastic than previously thought. The role of solar wind constituents heavier than protons and in particular the role of the particles charge state has so far been underestimated.

T cell antigen receptors act alone: longstanding immunological mystery solved!

Mario Brameshuber 2018-April-17

  • As an indispensable part of our immune system, T cells protect us from the onslaught of bacteria and viruses and also from cancer. What happens on a molecular level when T cells detect suspicious activity in the body? In a recent paper, Mario Brameshuber and co-workers from the Biophysics group and from the Medical University of Vienna revealed that the immune receptors of T cells operate in unsuspected ways. While most opinion leaders in the field reasoned that T cell receptors must interact with one another for effective immune-signaling, the Viennese study shows: T cell receptors act alone. The study has now been published in the journal “Nature Immunology”.

Avoiding the Polar Catastrophe

The labyrinth is the way out 2018-Feb-02

  • Ionic crystals - materials that are composed of positively and negatively charged ions - can be put into a highly unfavorable situation. When split in half along certain crystallographic directions the electrostatic energy diverges. To alleviate this so-called polar catastrophe, materials can react in a variety of ways. In a recent paper, Martin Setvin and co-workers from the Surface Physics group and from the University of Vienna show the surface of a KTaO3(001) single crystal after cleaving, heating, and exposure to water vapor. Six different mechanisms to compensate polarity are encountered. One of the most pretty solutions, a nano-labyrinth with 4-5 atom-wide walls, is shown in the image on the right.

Experiments conducted by Atomic and Plasma Physics Group of Fritz Aumayr with highly charged ions and graphene now show that the reason is an effect so far not accounted for: the so-called “interatomic coulomb decay”. Their results have now been published in the journal “Physical Review Letters” and have been highlighted there as “editors' suggestion”.

Switching Oxygen Molecules On and Off

2017-March-14 The qPlus sensor with the tip at the left

  • The oxygen molecule O2 is chemically inert (except at high temperatures), but becomes reactive when an additional electron gets added. This process happens in biology, catalysis and can be also triggered by light on some surfaces. Martin Setvin of the Surface Physics Group managed to switch oxygen molecules adsorbed at a titanium dioxide surface back and forth between the non-reactive (neutral) and reactive (O2-) state and examine them in detail using non-contact atomic-force microscopy (nc-AFM) with the tiny tip of a so-called qPlus sensor (image). The results were published in the prestigious journal Proceedings of the National Academy of Sciences of the USA (PNAS).

Elisabeth Gruber hits the TU headlines for the second time in this year!

Elisabeth Gruber 2016-Dec-21

  • With her first-author paper published today in Nature Communications, Elisabeth Gruber, PhD student in the Atomic and Plasma Physics Group of Fritz Aumayr, made the TU headlines already for the second time in this year (see the news from 2016-Aug-29 below). In her work, she demonstrated that graphene, a two-dimensional form of carbon, is able to provide tens of electrons for charge neutralization of a slow highly charged ion within a few femtoseconds only. This in turn results in extremely high current densities, which the graphene can withstand without suffering permanent damage.

Meteorite Impact on a Nano Scale

HCI-surface interaction 2016-August-29

  • A meteorite impacting the earth under a grazing angle of incidence can

do a lot of damage; it may travel a long way, carving a trench into the ground until it finally penetrates the surface. The impact site may be vaporized, there can be large areas of molten ground. All that remains is a crater, some debris, and an extensive trail of devastation on both sides of the impact site.

Hitting a surface with high-energy, heavy ions has quite similar effects – only on a much smaller scale. In a recent publication researchers from the IAP Atomic and Plasma Physics Group have investigated the microscopic structures which are formed when ions are fired at crystals at oblique angles of incidence and could shed light on the underlying formation mechanism.

The Pairing and Separation of Pt Atoms

2016-July-28 A Pt dimer at the Fe<sub>3</sub>O<sub>4</sub> surface

  • Sintering - the aggregation of catalytically active, metallic nanoparticles into bigger clumps - is one of the major causes of catalyst de-activation. This is particularly important in the emerging field of single-atom catalysis, the main research topic of the START project of Gareth Parkinson. A detailed STM and DFT study, mainly conducted by Roland Bliem, and published in PNAS, shows how single Pt atoms on the Fe3O4(001) surface are made mobile by CO, and how they merge into bigger clusters. Interestingly, the smallest cluster, a Pt dimer, is stabilized by the CO molecules. When the sample is heated, and the CO desorbs, and the two Pt atoms separate again.

Making it Stick on the Cover of Nature

2016-June-30

  • The article "Switching stiction and adhesion of a liquid on a solid" by Stijn Mertens et al. is featured on this week's cover of Nature Magazine. The work describes dynamic contact angle measurements of a single drop of 0.1 M HClO4 on a single layer of BN supported on Rh(111). Friction can be changed reversibly by applying an appropriate electrochemical potential that leads to the intercalation of H between BN and the Rh.
