SPITZER IRS spectra of Virgo early type galaxies: detection of stellar silicate emission
, 2006 We present high signal to noise ratio Spitzer Infrared Spectrograph observations of 17 Virgo early-type galaxies. The galaxies were selected from those that define the colour-magnitude relation of the cluster, with the aim of detecting the silicate ...

Advanced Materials Interfaces, EarlyView.This review explores how various surface pretreatment methods—such as heat treatment, severe plastic deformation, laser modification, immersion, and cold spray—enhance the performance of PEO coatings on magnesium alloys. The study highlights how these pretreatments influence coating microstructure, adhesion, and corrosion resistance, offering new ...

A complete census of silicate features in the mid-infrared spectra of active galaxies [PDF]
, 2015 We present a comprehensive study of the silicate features at 9.7 and 18 micron of a sample of almost 800 active galactic nuclei (AGN) with available spectra from the Spitzer InfraRed Spectrograph (IRS). We measure the strength of the silicate feature at 9.7 micron, S9.7, before and after subtracting the host galaxy emission from the IRS spectra.

High-Q bismuth silicate nonlinear glass microsphere resonators [PDF]
, 2012 The fabrication and characterization of a bismuth-silicate glass microsphere resonator has been demonstrated. At wavelengths near 1550 nm, high-modes can be efficiently excited in a 179 µm diameter bismuth-silicate glass microsphere via evanescent ...

Optical properties of non-stoichiometric amorphous silicates with application to circumstellar dust extinction [PDF]
, 2017 Optical constants of non-stoichiometric amorphous magnesium-iron silicates are determined. It is demonstrated that these can well reproduce the observed mid-infrared emission spectra of evolved stars. Stoichiometric and non-stoichiometric amorphous magnesium-iron silicate films are fabricated by pulsed laser deposition.
