Archaeological and Archaeometric Insights into a Roman Wall Painting Assemblage from the Blanes Dump (Mérida)
Castillo Alcántara, Gonzalo; Cosano, Daniel; Fernández Díaz, Alicia; Ruiz, José Rafael (MDPI, 2024)In this paper we describe the archaeological and archaeometric analysis of a Third Pompeian Style assemblage from the Blanes dump in Mérida (Spain). Based on the pottery context, the material would have been part of the ... -
Archaeometric identification of a perfume from Roman times
Cosano, Daniel; Román, Juan Manuel; Lafont, F.; Ruiz, José Rafael (MDPI, 2023)Although archaeological excavations have recovered a large number of vessels used to hold perfumes or ointments in ancient Rome, little is known about the chemical composition or origin of the substances they contained. ... -
Efficient Removal of Nonylphenol Isomers from Water by Use of Organo-Hydrotalcites
Cosano, Daniel; Esquivel, Dolores; Romero-Salguero, F.J.; Jiménez-Sanchidrián, César; Ruiz, José Rafael (MDPI, 2022)The presence of potent organic endocrine-disrupting chemicals (EDCs) in natural aquifers can have adverse impacts on public health and the environment. 4-nonylphenol, one such EDC, can be efficiently removed from water by ... -
Fast ultrasound-assisted synthesis of highly crystalline MIL-88A particles and their application as ethylene adsorbents
Amaro-Gahete, J.; Klee, Rafael; Esquivel, Dolores; Ruiz, José Rafael; Jiménez-Sanchidrián, César; Romero-Salguero, F.J. (Elsevier, 2019)Highly crystalline MIL-88A particles have been successfully synthesized via fast ultrasound-assisted processes. The influence of the sonication generator and synthesis time on the structure, crystallinity, morphology and ... -
