Infrared spectra of Mg-SiO smokes : comparison with analytical electron microscopy studies [PDF]

, 1985
An important component of current models for interstellar and circumstellar evolution is the infrared (IR)spectral data collected from stellar outflows around oxygen-rich stars and from the general interstellar medium [1]. IR spectra from these celestial

SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...

Hydroxylated Mg-rich Amorphous Silicates as Catalysts for Molecular Hydrogen Formation in the Interstellar Medium

The Astrophysical Journal
We present results from an experimental study on the interaction of atomic deuterium with magnesium-rich amorphous enstatite- and forsterite-type silicates. Infrared spectroscopy was used to examine the process. During deuterium atom exposure, deuteroxyl

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

HYDROGEN IN THE EARTH’S OUTER CORE, AND ITS ROLE IN THE DEEP EARTH GEODYNAMICS

Геодинамика и тектонофизика, 2016
The content of hydrogen in the outer core of the Earth is roughly quantified from the dependence of the density of iron (viewed as the main component of the core) on the amount of hydrogen dissolved in the core, with account of the most likely presence ...
