Tunable photon lifetime in photonic molecules: a concept for delaying an optical signal
(2005)
We experimentally and theoretically studied the photon lifetime spectral distribution in two coherently
coupled spherical microcavities of
3?16
m
diameter forming a photonic molecule, which shows a multi-
peak narrowband ...
Reply to ?Comment on `Size-dependent scaling of perpendicular exchange bias in magnetic nanostructures???
(American Physical Society, 2008)
Our observation of size-dependent scaling effects at room temperature in exchange-biased multilayers grown
onto arrays of polystyrene nanospheres Phys. Rev. B 75, 012413 2007 does not conflict with the observation

Metal surface enhanced emission from CdTe quantum dots
(IEEE, 2005)
In this paper the enhancement in emission from CdTe quantum dots (QDs) on Au island film as a function of CdTe-Au distance is reported. The observed enhancement can be partially explained by increased absorption cross ...
Exfoliation and dispersion of layered materials through liquid phase processing
(Trinity College (Dublin, Ireland). School of Physics, 2012)
Graphene is a nanomaterial that has been the focus of intense research efforts in recent times. Production methods that yield high quality graphene without the need for detrimental chemical processing are needed in order ...
Optical detection of electron-nuclear double resonance for an S=1 luminescent center in GaP:O
(1991)
The origin of a triplet (S=1) optically detected magnetic-resonance (ODMR) spectrum observed in the luminescence of GaP:O has been the subject of recent controversy. Originally identified with the negative-charge state of ...
The association of a J -burst with a solar jet
(2017)
Context. The Sun is an active star that produces large-scale energetic events such as solar flares and coronal mass ejections, and numerous smaller scale events such as solar jets. These events are often associated with ...
A comparison of catabolic pathways induced in primary macrophages by pristine single walled carbon nanotubes and pristine graphene
(2016)
Understanding the correlation between the physico-chemical properties of carbonaceous nanomaterials and how these properties impact on cells and subcellular mechanisms is critical to their risk assessment and safe translation ...
Magnetic properties of iron-rich Fe-Sc glasses
(American Physical Society, 1989)
Amorphous FexSc100-x alloys with x=89, 90, and 91, prepared by melt spinning, exhibit a single sharp spin-freezing transition at 100 3 K to an asperomagnetic state. The average Fe57 hyperfine field at 4.2 K is 22.7 T. ...
Mechanical properties of individual electrospun polymer-nanotube composite nanofibers
(2009)
Singlewalled carbon nanotube/polyvinylalcohol composite nanofibers were electro-spun onto a silicon surface pre-patterned with trenches. These nanofibers were prepared with different loadings of SWCNTs and had radii between ...
Contact-induced spin polarization in carbon nanotubes
(2004)
Motivated by the possibility of combining spintronics with molecular structures, we investigate the conditions for the appearance of spin polarization in low-dimensional tubular systems by contacting them to a magnetic ...
