Elusive light switch

Nanotube Light-controlled Electronic Switch

The use of carbon nanotubes for field effect nanoelectronic devices, which has been recently demonstrated, motivates further studies of electrochemical and chemical analogues of nanotube molecular transistors. However, chemical gating is not applicable for modern electronics due to its slow response. Herein we propose a novel molecular electronic device: Nanotube LightControlled Switch (NLCS). ...

Light Switch for DNA Mismatches

Elusive Knowledge" Elusive Knowledge'

We know a lot. I know what food penguins eat. I know that phones used to ring, but nowadays squeal, when someone calls up. I know that Essendon won the 1993 Grand Final. I know that here is a hand, and here is another. We have all sorts of everyday knowledge, and we have it in abundance. To doubt that would be absurd. At any rate, to doubt it in any serious and lasting way would be absurd; and ...

Structural Colour: Elusive Iridescence Strategies Brought to Light

Understanding structural colours in nature requires the right set of optical experiments: this is illustrated by a new study on iridescent bird of paradise feathers, which suggests the potential behavioural importance of dynamic colour changes.

Anomalous Internal Pair Conversion Signaling Elusive Light Neutral Particles

Abstract. In this paper we report on a systematic search for a neutral boson in the mass range between 5 and 15 MeV/c2 in the decay of highly excited nuclei. Its signature is found a deviation in the angular correlation of the e+e− pairs from conventional internal pair conversion (IPC) resulting from of its two-body decay kinematics. With an e+e− pair-spectrometer, a number of transitions has b...
