A Bochum-based team has developed a new process for zinc oxide layers that can be used for nitrogen oxide sensors as well as protection layer on plastic.The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which employs typically chemical compounds, or simply precursors, which ignite immediately upon contact with air, i.e. are highly pyrophoric. An interdisciplinary research team at Ruhr-Universität Bochum (RUB) has now established a new fabrication process based on a non-pyrophoric zinc precursor that can be processed at temperatures low enough to allow plastics to be coated.Depositing ultra-thin layersIn order to produ...

The electronics market is growing constantly and so is the demand for increasingly compact and efficient power electronic systems. The predominant electronic components based on silicon will in the foreseeable future no longer be able to meet the increasing industrial requirements. This is why scientists from the university of Freiburg, the Sustainability Center Freiburg and the Fraunhofer-Gesellschaft have joined forces in order to explore a new material structure that may be better suited for future power electronics.

Open-cell materials, such as metal and ceramic foams, have been extensively utilized in high-temperature applications due to their light weight, good flow-mixing capability, and ability to cover a large surface area. They are commonly composed of interconnected solid struts and accessible void spaces
