Tailoring microplasma nanofabrication: From nanostructures to nanoarchitectures
(Institute of Physics (IOP), 2009-04-15)
An innovative approach to fabricate tailored Mo-oxide nanostructures and composite nanoarchitectures using atmospheric microplasmas sustained in a gap between a Mo wire and a Si substrate is reported. It is shown that at ...
Ambient-stable blue luminescent silicon nanocrystals prepared by nanosecond-pulsed laser ablation in water
(2008 Optical Society of America, 2009-01-07)
Even with intensive research, air-stable blue light emission from silicon nanocrystals (Si-ncs) at room temperature still remains a challenge. We show that stable and blue-luminescent Si-ncs can be produced by ...
A holistic approach to schema matching
Post-Newtonian simulations of super-massive black hole binaries in galactic nuclei
(Wiley-VCH Verlag Berlin: Astronomische Nachrichten, 2008-12)
We present some preliminary results from recent numerical simulations that model the evolution of super-massive black hole (SMBH) binaries in galactic nuclei. Including the post-Newtonian terms for the binary system and ...
An Instability in triaxial stellar systems
(Wiley InterScience: Astronomische Nachrichten, 2008-12)
The radial-orbit instability is a collective phenomenon that has heretofore only been observed in spherical systems. We find that this instability occurs also in triaxial systems, as we checked by performing extensive ...
The Production of self-organized carbon connections between Ag nanoparticles using atmospheric microplasma synthesis
The formation of long self-organized carbon connections (where the length is much greater than the diameter) between Ag nanoparticles on a Si(100) surface in atmospheric pressure Ar + CH4 microplasmas is demonstrated. A ...
Integrating the determinants of suction feeding performance in centrarchid fishes
(Company of Biologists, 2008-10-07)
When suction-feeding vertebrates expand their buccal cavity to draw water into their mouth, they also exert a hydrodynamic force on their prey. This force is key to strike success, directly countering forces exerted by ...
A Hybrid N-Body Code incorporating algorithmic regularization and Post-Newtonian forces
(Wiley InterScience: Monthly Notices of the Royal Astronomical Society, 2008-07-24)
We describe a novel N-body code designed for simulations of the central regions of galaxies containing massive black holes. The code incorporates Mikkola’s “algorithmic” chain regularization scheme including post-Newtonian ...
Two more candidate AM Canum Venaticorum (AM CVn) Binaries from the Sloan Digital Sky Survey
(American Astronomical Society - The Astronomical Journal, 2008-06)
AM CVn systems are a select group of ultracompact binaries with the shortest orbital periods of any known binary subclass; mass-transfer is likely from a low-mass (partially-)degenerate secondary onto a white dwarf ...
