Near-infrared laser-mediated drug release and antibacterial activity of gold nanorod–sputtered titania nanotubes

Journal of Tissue Engineering, 2018
The infection control of implants is one of the hot issues in the field of medicine and dentistry. In this study, we prepared gold nanorod–sputtered titania nanotubes on titanium surface, which is the main component of implant material, and aimed to ...

Observations of convection in A-type stars [PDF]

, 2004
Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from A-type stars. The recent theoretical advancements in convection modelling have proved a challenge to the observers to obtain measurements with sufficient

Four nearby L dwarfs [PDF]

, 1999
We present spectroscopic, photometric and astrometric observations of four bright L dwarfs identified in the course of the 2MASS near-infrared survey. Our spectroscopic data extend to wavelengths shortward of 5000\AA in the L0 dwarf 2MASSJ0746+2000 and ...

The high-field polar RX J1007.5-2017 [PDF]

, 2012
We report optical and X-ray observations of the high-field polar RXJ1007.5-2017 performed between 1990 and 2012. It has an orbital period of 208.60 min determined from the ellipsoidal modulation of the secondary star in an extended low state.

Transmission enhancement through square coaxial apertures arrays in metallic film: when leaky modes filter infrared light

, 2014
We consider arrays of square coaxial apertures in a gold layer and study their diffractive behavior in the far infrared region. These structures exhibit a resonant transmission enhancement that is used to design tunable bandpass filters.

LkH$\alpha$ 330: Evidence for dust clearing through resolved submillimeter imaging [PDF]

, 2008
Mid-infrared spectrophotometric observations have revealed a small sub-class of circumstellar disks with spectral energy distributions (SEDs) suggestive of large inner gaps with low dust content.

Stellar Fluxes as Probes of Convection in Stellar Atmospheres [PDF]

, 2006
Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from late-type stars. The theoretical advancements in convection modelling over recent years have proved challenging for the observers to obtain measurements ...

An infrared-submillimeter study of star-forming regions selected by the ISOSS 170um survey

, 2008
Using the ISOPHOT Serendipity Survey (ISOSS) at 170um a sample of galactic star-forming regions exhibiting very cold dust temperatures (< 20 K) and high masses (> 100 M_sun) has been established.

Quantitative analysis of WC stars: Constraints on neon abundances from ISO/SWS spectroscopy [PDF]

, 2000
Neon abundances are derived in four Galactic WC stars -- gamma Vel (WR11, WC8+O7.5III), HD156385 (WR90, WC7), HD192103 (WR135, WC8), and WR146 (WC5+O8) - using mid-infrared fine structure lines obtained with ISO/SWS.
