The speciation of potentially toxic elements (PTE) in bottom ashes from municipal solid waste incineration (MSWI) and their relationship with grain size is investigated. proposed enrichment several potential lower sized grains discussed, comparing the literature new data on Parma’s incinerator. Results X-ray fluorescence spectrometry (XRF), SEM-EDS, XRD analyses different show (1) a positive Si...

In this work, the impregnation quality and mechanical properties of Pinus radiata D.Don treated with different copper nanoparticles (CuNP) solutions (named K1 K2) a commercial preservative (M) were studied. The pine wood was analyzed by two indicators, penetration retention. micro-distribution in qualitatively evaluated SEM-EDS, both samples containing CuNP those preservative. addition, some st...

Samples of a naturally bioreduced, U-contaminated alluvial sediment were characterized with various microscopic and spectroscopic techniques and wet chemical extraction methods. The objective was to investigate U association and interaction with minerals of the sediment. Bioreduced sediment comprises approximately 10% of an alluvial aquifer adjacent to the Colorado River, in Rifle, CO, that was...

Several techniques have been utilized for the preparation of hydroxyapatite (HA) and other calcium phosphates for the development of biomaterials. It is vital to know the reaction kinetics to be able to control the material obtained by the aqueous solution route. In the present work, HA has been produced by different wet precipitation processes and different experimental conditions. Calcium hyd...

The Alhambra Monumental Ensemble (Granada, Spain) is a unique well-preserved palatine city from the medieval Islamic period, and it constitutes best example of Nasrid architecture. In this work, we focus on study one its most unknown decorations: Wall paintings with appearance red bricks. These faux-brick decorations are found in many different locations within complex, including both exterior ...

Maya blue is a well-known pre-Hispanic pigment, composed of palygorskite or sepiolite and indigo blue, which was used by various Mesoamerican cultures for centuries. There has been limited research about its continued use during the Viceroyalty period; therefore, sixteenth century perfect period through to study continuity traditions. The fact that indigenous people were active participants in ...
