Vitreous materials are quite routinely found in natural settings. Most of them are
aluminosilicates, which often occur in large deposits. Considering the geological formations …

In modelling mass and heat transfer steps in metallurgical processes, it is important to have
knowledge of the physical properties of slags, the most important among these being the …

The emplacement behaviors and the associated hazards of silicic lavas remain poorly
understood because detailed real-time observations have only been made during a few …

A Raman microspectroscopic study of several fulgurites has been undertaken. A fulgurite is
an amorphous mineraloid, a superheated glassy solid that is formed when a lightning bolt …

The social aspect of modern hominin behaviour is a neglected subject within recent
Palaeolithic research. This thesis addresses this issue arguing that modern social behaviour …

The present study primarily involves the application of LIBS (Laser Induced Breakdown
Spectroscopy) technique for the characterization of moldavite, a shocked silica-rich glass …

Containerless aerodynamic levitation processing is a unique technology for the fabrication
of bulk non-crystalline materials. Using conventional aerodynamic levitation, a high …

This paper aims to evaluate the optical properties of natural rhyolite obsidians that might be
useful in the identification of different sources of archaeological samples. Even though …

This study discusses whether the prism used in a Kretschmann-based surface plasmon
sensor can be fabricated from a thermotropic liquid crystal (TLC) material. The refractive …

In this study, two types of the polyimide-silica hybrid thin films, 6FDA-ODA/SiO2 (FS0–FS50)
and PMDA-ODA/SiO2 (PS0–PS40), with different silica content were synthesized by using …
