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.

Origin and consequences of silicate glass passivation by surface layers
Nature Communications, 2015 Silicate glasses are durable materials, but are they sufficiently durable to confine highly radioactive wastes for hundreds of thousands years? Addressing this question requires a thorough understanding of the mechanisms underpinning aqueous corrosion of

Advanced Materials Interfaces, EarlyView.This study explores the synthesis and properties of hafnium‐titanium oxide (HTO) alloys developed by low‐temperature atomic layer deposition (ALD) as selective contacts for crystalline silicon solar cells. X‐ray photoelectron spectroscopy (XPS), surface photovoltage (SPV), and ellipsometry are employed to estimate the band alignment at the c‐Si/HTO ...

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.

Advanced Materials Interfaces, EarlyView.This study presents a novel silica‐based sol‐gel coating enhance with silica nanoparticles to protect glass surfaces. By reducing formulation acidity and improving resistance to environmental alteration—especially with 50 nm particles and double‐dip application—the method creates a gentle yet effective protective barrier.

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 ...

Effects of ionization on silicate glasses. [Silicate glasses] [PDF]
, 1982 This evaluation of radiation effects in silicate glasses caused by ionization is based on our own investigations, on material collected in our files (reports, articles, and notes), and on a computer literature search through recent issues of Physics Abstracts and Chemical Abstracts (and the apparently pertinent references which appeared).

Low temperature optical properties of interstellar and circumstellar icy silicate grain analogues in the mid-infrared spectral region [PDF]
, 2018 Two different silicate/water ice mixtures representing laboratory analogues of interstellar and circumstellar icy grains were produced in the laboratory. For the first time, optical constants, the real and imaginary parts of the complex refractive index, of such silicate/water ice mixtures were experimentally determined in the mid-infrared spectral ...
