The team produced and studied new active photocatalysts based on natural aluminosilicate nanotubes with cadmium sulfide quantum dots ...

Double-walled nanotubes have electro-optical advantages

01-Apr-2020 - One nanotube could be great for electronics applications, but there's new evidence that two could be tops. Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when ...

Energy Flow in the Nano Range

Two new spectroscopic methods

23-Oct-2019 - It is crucial for photovoltaics and other technical applications, how efficiently energy spreads in a small volume. With new methods, the path of energy in the nanometer range can now be followed precisely. Plants and bacteria lead the way: They can capture the energy of sunlight with ...

Coming a step closer to the dream of nanotechnology

Simple synthesis of seeds for standardised carbon nanotubes

02-Sep-2019 - Synthesising single-wall carbon nanotubes (SWCNTs) is one of the greatest challenges faced by materials science. They can be synthesised using precursor molecules, so-called seeds, which determine growth. However, this synthesis has not been well researched up to now. Researchers at FAU have now ...
