Scientists have uncovered the detailed structure of the aluminum oxide surface, a challenge that has baffled researchers for decades.
Scientists at the TU Wien and the University of Vienna have uncovered the detailed structure of the aluminum oxide surface, a challenge that has baffled researchers for decades.), also known as alumina, corundum, sapphire, or ruby, is one of the best insulators used in a wide range of applications: in electronic components, as a support material for catalysts, or as a chemically resistant ceramic, to name a few.
The three-dimensional model of the aluminum oxide surface was optimized with machine learning methods. The main challenge was to match the restructured surface with the underlying crystal."The structure is very complex, resulting in a vast number of possibilities for how the experimentally inaccessible atoms below the surface could be arranged.
Parts of the experimental setup housing the noncontact atomic force microscope have been patented: Passive vibration isolation for high-resolution microscopy. Producing clean water at a lower cost could be on the horizon after researchers solved a complex problem that has baffled scientists for decades, until ...
