Direct observation of quantum coherence in single-molecule magnets
(American Physical Society, 2008)
Direct evidence of quantum coherence in a single-molecule magnet in a frozen solution is reported with coherence times as long as T2=63030ns. We can strongly increase the coherence time by modifying the matrix in which the ...
Vertical nanowire light-emitting diode
(American Institute of Physics Inc, 2004)
We report room-temperature, white-color electroluminescence in vertically oriented ZnO nanowires. Excitonic luminescence around 380 nm is observed as a shoulder on a broader defect-related band covering all of the visible ...
Gamma-ray spectroscopy with relativistic exotic heavy-ions
(Indian Academy of Sciences, 2001)
Feasibility of gamma-ray spectroscopy at relativistic energies with exotic heavy-ions and new generation of germanium detectors (segmented Clover) is discussed. An experiment with such detector array and radioactive is discussed.

Two-dimensional metallo-dielectric photonic crystals embedded in anodic porous alumina for optical wavelengths
(AIP, 2004-08/23)
A theoretical study is presented for hexagonal lattice metallic pillar photonic crystals in anodic porous alumina with a lattice constant of 500 nm. The objective of the investigation is to design a two-dimensional ...
Switching mirror in the CdTe-based photonic crystal
(AIP, 2005-07/04)
Theoretical investigations, modeling and design of a Bragg mirror (photonic crystal structure) in the CdTe-based material system are presented. It is shown that, in addition to the third-order nonlinearity (Kerr-like ...
"Smart" baroreception along the aortic arch, with reference to essential hypertension
(American Physical Society, 2004)
An arterial model was used to show that the cumulative effects of wave reflections have a surprisingly pronounced effect on the pressure distribution in the root segment of the tree. Global arterial conditions play a role ...
Analysis of a rock slide stabilized with a toe-berm: A case study in British Columbia, Canada
(Elsevier, 2004)
Practical experience has shown that slope movement can be controlled by the placement of a berm near the toe of the moving mass. During construction of the Revelstoke project (British Columbia, Canada), excavation of a ...
