Experimental work involving artificial maturation of modern sediments was carried out to determine if diamondoids can be generated from biosynthetic precursors abundant in modern sediments. Mineral catalysts of distinctive properties, including montmorillonite K10, acidic aluminosilicate and CaCO3 were used in the hydrous pyrolysis of organic-rich modern sediments to examine which type of catal...

This study presents for the first time a systematic investigation of thermodynamic properties sodium aluminosilicate hydrate (N–A–S–H), through dissolution pure synthetic N–A–S–H gels.

Aluminosilicate glasses offer wide-ranging potential as enabling materials for a new generation of optical devices operating in harsh environments. In this work, nonconventional manufacturing process, the molten core method, is employed to fabricate and study sapphire (Al2O3) YAG (yttrium aluminum garnet) derived all-glass silicate fibers which femtosecond (fs) laser used imprint oriented nanos...

Conducting filaments of polyaniline have been prepared in the 3-nanometer-wide hexagonal channel system of the aluminosilicate MCM-41. Adsorption of aniline vapor into the dehydrated host, followed by reaction with peroxydisulfate, leads to encapsulated polyaniline filaments. Spectroscopic data show that the filaments are in the protonated emeraldine salt form, and chromatography indicates chai...

The authors demonstrate a new route to the fabrication of individual aluminosilicate microtubes that can act as micron-scale optical cylindrical resonators. The microtubes were prepared using a simple vacuum assisted wetting and filtration through a microchannel glass matrix. Microphotoluminescence spectra of the microtube cavity show sharp resonant modes with quality factors up to 3200. A stro...
