Simultaneous Thermal Analysis (STA): A Powerful Tool for Forensic Investigation of Geomaterials
No full textThe use of thermal methods has become common in modern geomaterial analysis laboratories. The simultaneous thermal analysis (STA) represents a valid support for the definition of the physical behavior of concerned samples, once subjected to a temperature variation. This chapter discusses the thermal behaviors of key mineralogical phases present in soils, in order to provide the readers with a valuable tool for optimizing the compatibility and applicability of the STA method in judicial forensic test purposes. To this end, the chapter presents literature evidences and case studies, including those from the authors’ own studies, where the STA methods have been successfully used in the judicial forensic field
The historical stones of Campania: from oblivion to rediscovery
No full text"The historical stones of Campania: from oblivion to
rediscovery", edited by Maurizio de Gennaro, Domenico
Calcaterra and Alessio Langella, is a book published by Luciano
Publisher, Naples. It has been realized with the contribution of
many researchers from the Universities Federico II (Naples) and
Sannio (Benevento), with the aim of spreading the knowledge of
the building materials used for centuries in the historical
architecture of Campania, also in the prospect of enhancing local
stones
Italian zeolitized rocks of technological interest
No full textLarge areas of Italian territory are covered by thick and widespread deposits of zeolite-bearing volcaniclastic products. The main zeolites are phillipsite and chabazite spread over the whole peninsula, and clinoptilolite recorded only in Sardinia. A trachylic to phonolitic glassy precursor accounts for the formation of the former zeolites characterized by low Si/Al ratios (≤3.00), while clinoplilolite is related to more acidic volcanism. The genesis of most of these zeolitized deposits is linked to pyroclastic flow emplacement mechanisms characterized by quite high temperatures and by the presence of abundant fluids. The main utilization of these materials has been and still is as dimension stones in the building industry. Currently, limited amounts are also employed in animal farming (dietary supplement, pet litter and manure deodorizer) and in agriculture as soil improvement and slow-release fertilizers. New fields of application have been proposed for these products on account of their easy availability, very low cost, their high-grade zeolites (50-70%), and good technological features such as high cation exchange capacities and adsorption properties

Evaluation of natural phillipsite and chabazite as cation exchangers for copper and zinc
No full textChabazite and phillipsite, two zeolites widespread in many volcaniclastic deposits in central-southern Italy, were evaluated as cation exchangers for the removal of copper and zinc from aqueous solution. Equilibrium and kinetics of copper and zinc exchange reactions for sodium were investigated in order to verify the selectivity and the uptake rate of both zeolites for these heavy metals. Thermodynamic quantities, such as equilibrium constant, K-a, and Delta G degrees, as well as rate constant, K, were computed, and they showed that Na-chabazite displays a moderate selectivity and a favorable kinetics for copper, whereas in ail the other cases uses in wastewater treatment are not recommended

Technological features of glazed Protomajolica ware from Benevento (Italy)
No full textThe production of glazed ceramics in Italy started in 13th century, following Islamic tradition and techniques. Protomajolica samples from two medieval archaeological sites in Benevento were analyzed from mineralogical and petrographical points of view to identify and characterize the local production of fine glazed wares. Samples are represented by jugs, amphorae, bowls and dishes finely decorated and covered by thin inner and/or outer glazed surfaces. The colour of almost all the investigated sherds varies from creamy to orange even though, from the same archaeological levels, dark grey coloured ceramic fragments likely affected by overburning of the paste (kiln refuses) were collected.Optical microscopy observations, chemical (XRF) and physical (XRD) analyses allowed to reconstruct the steps of the manufacture process, and to identify a homogeneous group of samples likely belonging to a local production area of Protomajolica, a ceramic class widespread over the Central-Southern Italy between the 13th and the 15th century

No full textThe Pottesman Collection in the British Museum. Early Dynastic and Sargonic administrative texts. With an Appendix on a Palmyrene Inscription
No full textEdizione, trascrizione, traduzione e commento di un frammento di iscrizione palmirena inedita presente nella collezione Pottesman del British Museum (Appendice Agostini).The British Museum houses a small collection of six cuneiform tablets and a Palmyrene dedicatory inscription purchased in 1987 from the private collection of Solomon Pottesman. The aim of the present contribution is to provide a catalog of this lot and an edition of the so far unpublished cuneiform texts. In the appendix, Alessio Agostini added the edition of the Palmyrene inscription, which would have otherwise gone beyond the capabilities of the present author
