Ion generation and ion trapping in liquid crystals by means of nanomaterials

NanoWerk.com - Tue, 09/04/2018 - 20:12
The reorientation of elongated liquid crystalline molecules under the action of the applied electric field is a major physical effect enabling the use of liquid crystals in a variety of applications. To improve liquid crystal devices, new liquid crystal-forming materials are required. Recently, by merging liquid crystals and nanotechnology, a new, non-synthetic way to produce advanced liquid crystal materials was proposed. In short, it was achieved by dispersing various types of nanomaterials in liquid crystals.

Terahertz spectroscopy enters the single-molecule regime

NanoWerk.com - Mon, 09/03/2018 - 19:57
Researchers showed that long-wavelength terahertz spectroscopy can detect motion of single molecules, not just molecular ensembles. They used a single-molecule transistor design, where pairs of metal electrodes trap isolated C60 molecules, focus the THz beam onto them, and measure current change caused by THz-induced oscillation.

Terahertz spectroscopy enters the single-molecule regime

ScienceDaily.com: Nanotechnology News - Mon, 09/03/2018 - 19:34
Researchers showed that long-wavelength terahertz (THz) spectroscopy can detect motion of single molecules, not just molecular ensembles. They used a single-molecule transistor design, where pairs of metal electrodes trap isolated C60 molecules, focus the THz beam onto them, and measure current change caused by THz-induced oscillation. Two vibrational peaks were recorded. The measurement was sensitive enough to register slight peak-splitting caused by electron charging. This could promote wider use of THz spectroscopy.
