Higher than 60% internal quantum efficiency of photoluminescence from amorphous silicon oxynitride thin films at wavelength of 470 nm

, 2014
We reported the study on the photoluminescence internal quantum efficiency (PL IQE) and external quantum efficiency (PL EQE) from the amorphous silicon oxynitride (a-SiNO) films, which were fabricated by plasma-enhanced chemical vapor deposition followed

A single-molecule magnet assembly exhibiting a dielectric transition at 470 K

, 2012
A triangular Dy(III) single-molecule magnet (SMM) exhibiting ferroelectric bistability is assembled in an acentric space group Pna21. Hysteresis loops associated with its SMM behavior together with a two-step slow relaxation of the magnetization are ...

UHF white space in Europe — A quantitative study into the potential of the 470–790 MHz band

International Symposium on Dynamic Spectrum Access Networks, 2011
In this paper we study the availability of TV white spaces in Europe. We focus specifically on the 470–790 MHz UHF band that is still predominantly used for TV broadcasting also after the digital dividend (frequency reallocation as part of transition to ...

The Minimal Gene Complement of Mycoplasma genitalium

Science, 1995
The complete nucleotide sequence (580,070 base pairs) of the Mycoplasma genitalium genome, the smallest known genome of any free-living organism, has been determined by whole-genome random sequencing and assembly.

Blue 470-nm light kills methicillin-resistant Staphylococcus aureus (MRSA) in vitro.

Photomedicine and Laser Surgery, 2009
BACKGROUND DATA In a previous study, we showed that 405-nm light photo-destroys methicillin-resistant Staphylococcus aureus (MRSA). The 390-420 nm spectral width of the 405-nm superluminous diode (SLD) source may raise safety concerns in clinical ...
