Effects of Silicon Compounds on Biomineralization, Osteogenesis, and Hard Tissue Formation

open access: yesPharmaceutics, 2019
Bioinspired stem cell-based hard tissue engineering includes numerous aspects: The synthesis and fabrication of appropriate scaffold materials, their analytical characterization, and guided osteogenesis using the sustained release of osteoinducing and/or

Mass-loss and silicate production in oxygen-rich AGB stars: current understanding and open questions

open access: yesFrontiers in Astronomy and Space Sciences
AGB stars play a crucial role in the chemical enrichment of the Universe, polluting their host galaxies with gas and dust that reflect the nucleosynthesis processes active during their evolution.

Microwave emission from granular silicates [PDF]

open access: yes, 1973
Experimental finding is that mass absorption coefficient is independent of frequency but highly dependent on moisture content; effective conductivity increases with frequency, and low tangent is independent of frequency.

Effects of ionization on silicate glasses. [Silicate glasses] [PDF]

open access: yes, 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]

open access: yes, 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 ...

Nutrient analysis in estuarine water. Effect of salinity

open access: yesCiencias Marinas, 2003
The continous flow autoanalyzer is an instrument commonly used for nutrient analysis in coastal laboratories and oceanographic vessels. The determination of micronutrient concentrations (ammonium, nitrites, nitrates, silicates and phosphates) makes it ...

Dust formation around AGB and SAGB stars: a trend with metallicity?

open access: yes, 2012
We calculate the dust formed around AGB and SAGB stars of metallicity Z=0.008 by following the evolution of models with masses in the range ...

A comparative study of the continuum and emission characteristics of comet dust. 1: Are the silicates in Comet Halley and Kohoutek amorphous or crystalline [PDF]

open access: yes
A continuum emission was subtracted from the 10 micron emission observed towards comets Halley and Kohoutek. The 10 micron excess emissions were compared with BN absorption and laboratory amorphous silicates.

Characterization of charging ability of the silicate minerals [PDF]

open access: yesActa Montanistica Slovaca, 2004
To separate granular material it is important to knowi its charging ability. In this contribution the method of charge determination of particles due to the triboelectric charging is described.
