Sangre de nobles, mártires y pecadores. Los caballeros de San Juan entre la reforma religiosa y la vida militar
2018
After the fall of Rhodes in 1522, the Order of St. John needed to recover new headquarters (which were finally established in Malta in 1530) and its reputation as militia Christi. This Religion in arms had now to redraft its chivalrous ideals within the new context of the Reformation and the Catholic Renewal. However, Hospitallers met this challenge partially and late, although they represented themselves as belonging to this glorious Religion. Such a dialectic between practice and theory is proved, for example, by an apologetic book published in 1619 in Italy and Spain, as well as by unpublished instructions in the late seventeenth century directed at the chaplains providing religious supp…
Separation of Nanoparticles by Gel Electrophoresis According to Size and Shape
2007
We demonstrate the separation of gold and silver nanoparticles according to their size and shape by agarose gel electrophoresis after coating them with a charged polymer layer. The separation is monitored optically using the size- and shape-dependent plasmon resonance of noble metal particles and confirmed by transmission electron microscopy (TEM). Electrophoretic mobilities are quantitatively explained by a model based on the Henry formula, providing a theoretical framework for predicting gel mobilities of polymer coated nanoparticles.
Laser-Ablation-Induced Synthesis of SiO2-Capped Noble Metal Nanoparticles in a Single Step
2010
Here we describe a simple, powerful technique based on the laser ablation of a target immersed in a water solution of a metal salt. With this method, nanoparticles of different metals and alloys can be processed very quickly. Both the target and the salt solution can be chosen to produce metal nanoparticles of different sizes, surface-oxidized nanoparticles (silica-silver, for example), or even more complex structures to be defined by the researcher on one or more steps because the technique combines the advantages of both physical and chemical methods. We have applied this technique to the fabrication of inert silica-metal (silver, gold, and silver-gold) nanoparticles with a strong surface…
L'arquitectura dins la cultura nobiliària a Xàtiva
2018
El present treball busca analitzar i destacar aquelles arquitectures que l’estament nobiliari de Xàtiva va manar construir amb la finalitat de mostrar el seu poder al poble. Així mateix, és un intent de fer valer els edificis i els elements que se n’han conservat fins als nostres dies. La metodologia seguida consta d’una primera anàlisi del parc edificat per avaluar-ne l’arquitectura i d’una cerca a diferents arxius per conèixer l’evolució, tant de les construccions com de les diferents nissagues que les van habitar. Tot això ens permet concloure que, en el cas xativí, existeix una xifra elevada d’edificis erigits per la classe nobiliària que encara hui es mantenen dempeus, a la vegada que …
The New Generation of Resonant Laser Ionization Mass Spectrometers: Becoming Competitive for Selective Atomic Ultra-Trace Determination?
2002
A critical assessment of the present status of resonant laser ionization mass spectrometry (RIMS) as a specialized analytical technique for the field of atomic ultra-trace determination is attempted and a comparison with established mass spectrometric methods is made. Within the last years RIMS on atomic species has rapidly developed towards becoming a versatile experimental technique, in particular addressing those applications that require high selectivity in respect of isobaric or isotopic interferences. This progress is mainly based on the advent of easy-to-handle tunable solid-state laser systems for both pulsed and continuous operation, which are used in combination with modern compac…
High gas pressure: An innovative method for the inactivation of dried bacterial spores
2012
In this article, an original non-thermal process to inactivate dehydrated bacterial spores is described. The use of gases such as nitrogen or argon as transmission media under high isostatic pressure led to an inactivation of over 2 logs CFU/g of Bacillus subtilis spores at 430 MPa, room temperature, for a 1 min treatment. A major requirement for the effectiveness of the process resided in the highly dehydrated state of the spores. Only a water activity below 0.3 led to substantial inactivation. The solubility of the gas in the lipid components of the spore and its diffusion properties was essential to inactivation. The main phenomenon involved seems to be the sorption of the gas under pres…

On the Interaction of Carbon Nanowires with Noble Metals through a Study of Their Surface-Enhanced Raman Spectra
2008
This paper deals with the interaction of linear carbon chains (polyynes) with silver and gold surfaces in the form of nanometer-sized clusters. Surface-enhanced Raman signals have been detected rev...
Noble-gas bubbles in metals: Molecular-dynamics simulations and positron states.
1987
A theoretical treatment of atomic structure and positron states in noble-gas bubbles in metals is presented. The Al-He and Cu-Kr systems are considered as specific examples. For large bubbles (radii above a few tens of angstroms) a calculational scheme is developed combining molecular-dynamics results for the metal--noble-gas interface with positron calculations. It is demonstrated that a positron is trapped at the surface of a noble-gas bubble, i.e., at the metal-gas interface. The annihilation rate with metal electrons is similar to that at a clean surface, while simultaneously there is a significant annihilation rate with gas-atom electrons. This enables relationships between the gas den…
