To study brain cell's operation and test the effect of medication on individual cells, the conventional Petri dish with flat electrodes is not sufficient. For truly realistic studies, cells have to flourish within three-dimensional surroundings.
Researchers have discovered a new phosphor that could make next-generation fluorescent and LED lighting even cheaper and more efficient. The team used highly luminescent clusters of silver atoms and the porous framework of minerals known as zeolites.
Gemeinsam mit Wissenschaftlern von zehn Partnerinstitutionen aus 5 EU Laendern setzen Radiologen des Uniklinikums Jena ihre Forschungsarbeit an multifunktionellen magnetischen Nanopartikeln fort, die zur Detektion und Bekaempfung von Krebs eingesetzt werden sollen.
Previous attempts to grow germanene show that these attractive properties seem to vanish when it is grown on a metal surface: a good conductor of current. To prevent this, scientists chose the semiconductor MoS2 as the substrate material.
While this nanotechnology could significantly enhance our food, it also raises big questions about safety. We only have to look at the strong reaction against genetically modified foods to see how important this issue is. How can we ensure that nanotechnology in food will be different?
Physicists studied an artificial structure composed of alternating layers of ferromagnetic and superconducting materials. Charge density waves induced by the interfaces were found to extend deeply into the superconducting regions, indicating new ways to manipulate superconductivity.
Researchers use simulations to identify previously undiscovered semiconductors with promising attributes for optical and electronic applications. A nitride among those proposed has been successfully fabricated using high-pressure synthesis and is found to emit red light.
