A novel design of combustion catalysts is proposed, in which clay/TiO₂/MnAl-mixed oxide composites are formed by intermixing exfoliated organo-montmorillonite with oxide precursors (hydrotalcite-like in the case of Mn-Al oxide) obtained by an inverse microemulsion method. In order to assess the catalysts' thermal stability, two calcination temperatures were employed: 450 and 600 °C. The composi...

This work applies established analytical techniques of physical sciences to Irish brick in order to gather evidence of ceramic technologies, provenance and sources of raw materials. Petrographic microscopy, X-ray diffractometry and scanning electron microscopy with an energy dispersive Xray diffraction attachment were used to study the brick of Rathfarham Castle, Dublin, built c.1618, where cla...

Nowadays, new materials are widely used for improving the bearing capacity of the soils and geosynthetics include the type of these materials which are utilized in this regard. In addition, the geofoam panel type of geosyntethic materials is useful and an alternative for backfill in retaining wall or pavement layers. The present research mainly aimed to investigate sthe effects of geofoam parti...

A newly discovered Naomugeng lithium mineralization area is located to the east of Central Asian Orogenic Belt (CAOB). The hosted in volcanic rocks Manketou’ebo Formation. altered mainly consist quartz, orthoclase, chlorite, montmorillonite, calcite, and dolomite. Here, we present integrated studies petrography, mineralogy, geochemistry (with an average Li2O content 0.43 wt.%) collected from dr...
