Fossil bones, together with teeth, are the most common remains of vertebrates that could manage to get preserved over geological times, providing information on diagenetic and fossilization processes occurred in depositional paleoenvironment. bones from marine vertebrate Konservat-Lagerstätte East Pisco Basin Sacaco area (Peru) show a high variety different textural chemical features, suggestiv...

The objective of this study is to describe the mineralogical composition and chemical properties Ora?u Nou bentonite, from northwestern Romania. For determinations, following were used: X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FR-IR), thermogravimetric analysis, scanning electron microscopy coupled with energy-dispersive (SEM-EDX). compositions physical bentonites bento...

Mineralogical and chemical evaluations are necessary to investigate the background origins of materials. In terms residues commonly produced around world, ashes biomass stands out for its high calorific capacity use energy production at thermoelectrical facilities. Given current sustainability issues new demands from society, soil pine in Castelo Branco region were investigated research possibl...

This paper presents a chemical-mineralogical characterization of construction materials from medieval Renaissance buildings Ferrara (NE Italy) to provide an insight into the nature and provenance raw used. Biagio Rossetti was Italian architect urbanist city Ferrara. From 1483, he Duke Ercole I d’Este who in 1492 assigned him project enlarging is still famous because designed built many notable ...

Extraction of hydrocarbons from oil sand deposits relies on technologies designed to lower bitumen viscosity, either by thermal energy or combination and solvents. Thermal is commonly delivered steam. Once-through steam generators (OTSGs) are the most common class used generate boiler feed water (BFW) at high pressure temperature. Generated mobilize in situ reservoirs, then water-bitumen emulsi...

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...

The paper presents and analyzes the mineralogical, physical and chemical composition of dust deposited samples at six sites on the KAUST campus. KAUST is located on the Red sea coastal plain of Saudi Arabia. Monthly samples were collected between December 2014 and December 2015. The monthly deposition trends were compared to visibility and sun photometric measurements and to previous mineralogi...
