Encapsulation of hydrophilic and lipophilized catechin into nanoparticles through emulsion electrospraying
2017
In this work, we investigated the potential of emulsion electrospraying that contained bacterial cellulose and proteins for the encapsulation of epigallocatechin gallate (EGCG). Specifically, two different catechins, hydrophilic (H-EGCG) or lipophilized (L-EGCG), were encapsulated either on the aqueous or the oily phase of the emulsions in order to compare the antioxidants’ stability. Emulsion properties in terms of stability, droplet size, bulk and interfacial viscosity were studied combined with the evaluation of the properties of the produced particles, namely the morphology and size of the particles, the encapsulation efficiency (EE) of catechin and the stability of the EGCG within the …
Epigrafía árabe del Emirato (siglo IX). Lápida de Tudela y estela de una omeya
2018
Repaso de la epigrafía del emirato y del protocolo de sus epitafios, con edición, traducción y estudio de dos piezas labradas con escritura árabe de estilo cúfico «arcaico». Una lápida se halló, fuera de contexto, en excavaciones practicadas junto a la catedral de Tudela; la otra es el epitafio de una dama Omeya descubierto antes de 1960, sin duda en la ciudad de Córdoba. Estas lápidas emirales se incorporan a la treintena de inscripciones conocidas del siglo IX en la Península Ibérica. 
 
 
 
 
Micro-Raman spectroscopy of pigments contained in different calcium carbonate polymorphs from freshwater cultured pearls
2008
The metastable calcium carbonate polymorph vaterite has recently been found to occur commonly in freshwater cultured pearls from Japan and China. Organic pigment molecules in these vaterite regions of freshwater cultured pearls were analysed by resonance and near-resonance micro-Raman spectroscopy, in single spectra and in mapping modes and are compared with their aragonitic counterparts. Four different excitation wavelengths (487.9, 514.5, 532.2 and 632.8 nm) were used, resulting in differential increase of resolution for the pigments. Although vaterite areas were always lightly coloured (light yellow, light brown or white), ten different pigments were identified and a single colour is for…
Les différents modes d'évocation des défunts chez Les Eduens, les Lingons et les Séquanes au Haut-Empire (Ier - IIIème siècle) : de l'épigraphie à la…
2018
This new study of funerary monuments in Roman Gaul aims at putting emphasis on the various tools used by the ancient populations to perpetuate the memories of their dead. Thanks to carved images or texts, the mention of the name, of the identity of the deceased and of specific aspects of his everyday life were some of the means used to keep his memory alive in the world of the living. The geographical area chosen corresponds to three ancient territories : thoose of the Aeduens, the Lingons and the Sequans. Geographically and culturally close, these territories show indeed the same funeral traditions in ancient times. As for the chronological frame, it is limited to the Early Roman Empire, f…
Environmental drivers and abrupt changes of phytoplankton community in temperate lake Lielais Svētiņu, Eastern Latvia, over the last Post-Glacial per…

Understanding the long-term dynamics of ecological communities on the centuries-to-millennia scale is important for explaining the emergence of present-day biodiversity patterns and for predicting possible future scenarios. Fossil pigments and ancient DNA present in various sedimentary deposits can be analysed to study long-term changes in ecological communities. We analysed recent compilations of data, including fossil pigments, microfossils, and molecular inventories from the sedimentary archives, to understand the impact of gradual versus abrupt climate changes on the ecosystem status of a regional model lake over the last ~14.5 kyr. Such long and complete paleo-archives are scarce in No…

La fase del Ibérico final en el asentamiento del Torrelló del Boverot (Almazora, Castellón): dos piezas cerámicas singulares
2000
Since the end of 1988, when excavation was resumed at the Torrelló del Boverot site in Almazora (Castellón), large amounts of material —mostly ceramics— have been recovered, dating from the end of the Iberian period, which, chronologically, marked the end of the village's life. This paper discusses two unusual ceramic pieces from this late period, documented during the excavations that took place in 1995, undertaken in the central area of the site. The records obtained in this work matches that of a batch of materials donated to the Museum of Almazora by the amateurs who excavated this village in the mid-1970s.
CORRELATION BETWEEN SPECTRAL, SEM/EDX AND ELECTROCHEMICAL PROPERTIES OF MAYA BLUE: A CHEMOMETRIC STUDY*
2009
Visible spectra, composition from SEM/EDX and solid-state electrochemical data are correlated for a set of 12 Maya Blue samples from different archaeological sites of Campeche and Yucatan (Mexico). In addition to indigo and dehydroindigo, indirubin and other possibly indigo-type compounds can be detected in Maya Blue samples. Application of hierarchical cluster analysis techniques allows similarity relationships to be established between samples from different sites, confirming prior results which suggest that the preparation of Maya Blue pigment evolved with time during the Maya culture following a ramified scheme.
Stèles funéraires d'époque ibérique
2003
We wish to present in this paper a general study of the funereal stelas in Iberian culture. We begin with the analysis of the Peninsular tradition preceding the development of the Iberian world in order to consider this type of funereal monument within the landscape of cemeteries which seem to be more and more complex and varied. We will assess the different groups of stelas (5th-1st centuries B.C.) on the basis of their morphology, iconography and, in some cases, epigraphs. We present some examples from the provinces of Castellón and Teruel which have been subjected to recent studies.
IDENTIFICATION, PROCESSING AND USE OF RED PIGMENTS (HEMATITE AND CINNABAR) IN THE VALENCIAN EARLY NEOLITHIC (SPAIN)
2012
The results of the first elemental and structural physicochemical analyses (SEM–EDX, TXRF, XRD, FTIR, GC and EDXRF) of Early Neolithic red pigment samples from the region of Valencia confirm one of the earliest uses of cinnabar (HgS) in Spain (5300 to 5000 cal bc). They also inform on the storage of massive quantities of hematite and the development of specific technologies of hematite-based paint production and use. The samples were recovered at the three most significant Early Neolithic sites of the Mediterranean coast of Spain: Cova de l'Or (Beniarres, Alacant), Cova de la Sarsa (Bocairent, Valencia) and Cova Fosca (Vall d'Ebo, Valencia), which together have provided the most important E…
