3D Printing of nanoscale glass structures without sintering

Jun 15, 2023 (Nanowerk News) A new process developed at the Karlsruhe Institute of Technology (KIT) enables printing of nanometer-scale quartz glass structures directly onto semiconductor chips. A hybrid organic-inorganic polymer resin is used as feedstock material for 3D printing of silicon dioxide. Since the process works without sintering, the...

A band-aid with sensor function

Jun 15, 2023 (Nanowerk News) To ensure that wounds remain tightly sealed in the abdomen after surgery, researchers at Empa and ETH Zurich have developed a patch with a sensor function. The polymer patch warns before the occurence of dangerous leaks on sutures in the gastrointestinal tract take hold, while...

Ultrafast and tunable: Graphene-based terahertz-to-visible light conversion

Jun 15, 2023 (Nanowerk News) A study carried out by a research team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), University of Exeter Centre for Graphene Science, and TU Eindhoven demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible...
