Alpha radiometry of uranium in surface and ground waters by liquid scintillation counting after separation of the radionuclide by cation exchange
(2008)The alpha radioactivity of surface and ground water samples has been determined by liquid scintillation counting (LSC) after chemical preparation of the samples by cation exchange using the Chelex 100 resin. The method ...

Determination of aquatic radon by liquid scintillation counting and airborne radon monitoring system
(2008)This paper presents an airborne radon monitoring (RM) system for aquatic radon determination after out-gassing of radon from the aqueous sample and compares this method with the standard ASTM method for radon analysis in ...

Förster resonant energy transfer from an inorganic quantum well to a molecular material: Unexplored aspects, losses, and implications to applications
(2015)A systematic investigation of Förster resonant energy transfer (FRET) is reported within a hybrid prototype structure based on nitride single quantum well (SQW) donors and light emitting polymer acceptors. Self-consistent ...

InAs quantum dots grown by molecular beam epitaxy on GaAs (211)B polar substrates
(2006)InAs nanostructures were grown by molecular beam epitaxy on GaAs (211)B at temperatures between 400-530 °C and growth rates that were varied between 0.1 to 0.02 mono-layers (ML) per second. For temperatures up to 500 °C ...

Spin polarisation and anomalous Hall effect in NiMnSb films
(2004)NiMnSb has attracted a great deal of interest as a spin injector/detector in spintronic devices because it has a Curie temperature of 728 K and is predicted to be half-metallic (100% spin polarized). NiMnSb has been reported ...
