Crystalline calcium carbonate was deposited on various substrates (substrate temperature of 80 °C) from a saturated hydrogen solution (solution 10 °C). A single aragonite phase the Al substrate, whereas mixed and calcite grew soda lime glass, borosilicate silica polycarbonate substrates. With increasing deposition time, crystal size proportion silicate glass substrate increased. Furthermore, cr...

It is a well-known fact that the spectra of oxygen-rich circumstellar dust envelopes around evolved stars show great diversity, especially in the 10 μm silicate band profiles, but also in the longer infrared wavelength range covered by ISO. This supports earlier conclusions that the concept of a universal cosmic silicate is inadequate and that it is reasonable to consider a wider variety of pos...

Oxide glasses are dielectric materials with potential applications in high-frequency communications; hence, their properties the gigahertz to terahertz frequency range should be investigated. In this study, of silica glass and five single alkali silicate were measured at 0.5–10 THz using time-domain spectroscopy (THz-TDS) far-infrared (FIR) spectroscopic ellipsometry. At THz, exhibited low disp...
