Result of the Month (ROM), June 2022

The State of Zinc in Methanol Synthesis over a Zn/ZnO/Cu(211) Model Catalyst

In the latest study, Peter Amann et al. have for the first time been able to study the surface of a copper-zinc catalyst when carbon dioxide is reduced to methanol. They used XPS at 180 to 500 millibar to probe the nature of Zn and reaction intermediates during CO2/CO hydrogenation over Zn/ZnO/Cu(211), where the temperature is sufficiently high for the reaction to rapidly turn over, thus creating an almost adsorbate-free surface. The results reveal a specific role of CO in the formation of the Zn-Cu surface alloy as an active phase that facilitates efficient CO2 methanol synthesis. Using a well-focused and low-divergence x-ray beam from beamline P22 at the Petra III synchrotron radiation facility at DESY they probed the surface under extreme grazing incidence conditions using the BAR XPS endstation, developed by Stockholm University and commercialized by Scienta Omicron.

Product Demonstration

DFS30 Analyser Demonstration at MAX IV Laboratory

On-site collaborations are an exciting way to stay at the cutting edge of science. Recently Scienta Omicron engineers Anders Frisk and Patrik Karlsson visited MAX IV Laboratory to demonstrate the DFS30, our latest analyser, and the advantages for µARPES. The DFS30 is based on brand new Electrostatic 3D Focus Adjustment technology with dynamic electron optics that are quickly adjusted electronically to the emission spot and as experimental parameters are changed. This technology replaces time consuming yet critical mechanical optimisation of sample and photon source necessary for high quality deflection ARPES. With the DFS30, the experimental geometry can be kept fixed while still ensuring highest quality µARPES measurements.

Research News

Scientists Emulate Nature in Quantum Leap Towards Computers of the Future

A team of quantum computer physicists at UNSW Sydney led by Professor Michelle Simmons has achieved a major milestone in the race to build the world’s first quantum computer. They have built a quantum processor in silicon to simulate an organic molecule with astounding precision. They described in their recently published Nature paper, how they were able to mimic the structure and energy states of the organic compound polyacetylene – a repeating chain of carbon and hydrogen atoms distinguished by alternating single and double bonds of carbon. They utilize the atomic-precision placement accuracy of the STM to engineer quantum dots with large on-site energies (U ≈ 25 meV) and uniform size to realize a homogeneous linear array for reliable simulation accuracy.

Study Uncovers How Structural Changes Affect the Superconducting Properties of a Metal Oxide

Research opens the door for further study of superconductivity and the creation of more efficient semiconductors. A team led by University of Minnesota Twin Cities researchers has discovered how subtle structural changes in strontium titanate, a metal oxide semiconductor, can alter the material’s electrical resistance. The hybrid MBE system (EVO-50 MBE) from Scienta Omicron was used for film growth. The research can help guide future experiments and materials design related to superconductivity and the creation of more efficient semiconductors for various electronic device applications.

Product Installation

Scienta Omicron NanoESCA III at Flinders University, Australia

We are super excited and proud to see that the Scienta Omicron NanoESCA III photoemission electron spectroscopy (PEEM) has recently been commissioned at Flinders University. In an Australian first, the NanoESCA System to provide researchers and industry access to techniques for investigating material properties and structure. On this occasion, Prof. Robert Saint AM, Flinders University’s Deputy Vice-Chancellor (Research), said the facility can examine structural, morphological, electrical, and chemical aspects of a wide range of materials to nanometer resolutions.

“This amazing new facility is designed for current and future Australian research priorities across many industries, which can benefit from using this diverse and powerful technique,” says Flinders Microscopy and Microanalysis director Professor Sarah Harmer.
