Fine felted nanotubes

08/12/2017

Due to their unique properties, carbon nanotubes would be ideal for numerous applications, but to date they cannot be combined adequately with other materials, or they lose their beneficial properties. Scientists from Kiel University and the University of Trento have developed an alternative method of combining, so they retain their characteristic properties. As such, they 'felt' the ...

Light facilitates n-doping of organic semiconductors

07/12/2017

Doping organic semiconductors with negative charges is difficult. Now a German-American research team has applied a trick: as a first step, they transformed the fragile charge-donor molecules into dimers that are far more stable. These dimers can be introduced into organic semiconductors, but they do not contribute to the conductivity right away. Via short exposure to light ...

Mainz physicists propose a new method for monitoring nuclear waste

06/12/2017

New scientific findings suggest neutrino detectors may play an important role in ensuring better monitoring and safer storage of radioactive material in nuclear waste repository sites. Researchers at Johannes Gutenberg University Mainz (JGU) in Germany have made calculations to ascertain the neutrino radiation of spent nuclear fuel emits. Their figures show that neutrino detectors could be ...

Tuning the wavelength of fluorescent carbon tubes

05/12/2017

A research team at Japan's Kyushu University studied the fluorescence of carbon nanotubes (CNTs) made from graphene sheets a single atom thick. Various hexagonal organic molecules were bonded to the CNTs' outer wall. The wavelength of infrared emission from the CNTs could be tuned depending on which elements (e.g., bromine or nitrogen) were attached to the organic molecules, and ...

Watching atoms move in hybrid perovskite crystals reveals clues to improving solar cells

05/12/2017

The discovery of nanoscale changes deep inside hybrid perovskites could shed light on developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, a team of researchers led by the University of California San Diego discovered how the movement of ions in hybrid perovskites causes certain regions within the material to become better solar cells than other parts.

Physicists explain metallic conductivity of thin carbon nanotube films

04/12/2017

A group of researchers has examined the optical and dielectric properties of thin macroscopic films based on single-walled carbon nanotubes and obtained an explanation for the metallic nature of their conductivity using infrared and terahertz spectroscopy. The research findings were published in the journals Carbon and Nanotechnology
