Effects of Crystal Field Splitting and Surface Faceting on the Electronic Shell Structure

1992

The shell structure of the valence electrons is clearly observed in all alkali and noble metal clusters containing up to hundreds of atoms[1 – 4]. It is seen in the abundances of the clusters, in the ionization potential and in the polarizability. The shell structure of the valence electrons is closely related to the shell model of nuclei, but is simpler owing to the negligibly small spin-orbit interaction. The ability to produce all sizes of metal clusters has made the metal clusters a test ground for the super-shell structure[5].

Spectroscopic evidence for a new type of surface resonance at noble metal surfaces

2020

We investigated the surface and bulk properties of the pristine (110) surface of silver using threshold photoemission by excitation with light of 5.9 eV. Using a momentum microscope, we identified two distinct transitions along the $\overline{\mathrm{\ensuremath{\Gamma}}}\overline{\mathrm{Y}}$ direction of the crystal. The first one is a so far unknown surface resonance of the (110) noble-metal surface, exhibiting an exceptionally large bulk character that has so far been elusive in surface sensitive experiments. The second one stems from the well-known bulklike Mahan cone oriented along the $\mathrm{\ensuremath{\Gamma}}L$ direction inside the crystal but projected onto the (110)-surface cu…

La stereotomia nella cattedra di Architettura statica di Carlo Giachery

2014

La scuola di architettura di Palermo, sin dalla sua fondazione nel 1779, con la creazione della cattedra di Architettura civile affidata a Giuseppe Venanzio Marvuglia, era divenuta inevitabilmente il luogo di verifica e talvolta di esplorazione dei temi legati alla pratica professionale e, quindi, all’arte del costruire. Giachery, Professore di Architettura statica e civile dal 1837 al 1865, è il primo ad avvertire, da docente, la crisi profonda del sistema didattico della scuola di architettura di Palermo isterilita dalla ricerca di astratte idealità neoclassiche e straniatasi dal processo evolutivo della cultura architettonica europea dopo la morte dei “maestri” Marviglia e Gentile. Secon…

The School of Architecture of Palermo since its founding in 1779 with the creation of the chair of Civil Architecture entrusted to Joseph Venantius Marvuglia has become the place of testing exploration of issues related to professional practice and the art of building. Carlo Giachery Professor of Static and Civil Architecture from 1837 to 1865 is the first to feel the deep crisis of the educational system of the school of architecture of Palermo. For him architecture and applied sciences to architecture found in their stereotomy confirmation of the existence of correspondent relationships in their evolutionary process. The notion of stereotomy taken by Carlo Giachery in teaching reconnects directly to the noble art of coupe des pierres. Taken together the teaching aids used to show a theoretical advance that Giachery inclined in the direction of elasticity of the materials. Noting the outcomes of teaching his students have the clear perception of how the teaching on stereotomy is the compendium of all the French tradition on the subject. With the establishment of the School of Application for Engineers and Architects in 1866 the steretomia seems to gradually lose interest in favor of the prevailing metal construction. All the wisdom of build which for centuries had been linked with art de la coupe des pierres gave way to new construction techniques and new materials.Settore ICAR/14 - Composizione Architettonica E Urbana

La casa de Almenara a través de la historia (ss. xiii-xviii)

2018

El trabajo que presentamos, La Casa de Almenara a través de la historia. ss. XIII-XVIII, pretende ofrecer una nueva perspectiva sobre la estirpe nobiliaria de los Próxita, un linaje cuya presencia en la primera línea de la escena política y militar, al servicio de los reyes de la Corona de Aragón, se remonta al siglo XIII en el ámbito italiano. A partir de una abundante y variada tipología de fuentes archivísticas, y en el marco historiográfico actual de los estudios sobre nobleza y poder, hemos focalizado nuestra atención en dos ámbitos diferenciados. Por un lado, y como hilo conductor, la relevancia de cada uno de los personajes que fueron cabeza de la Casa o ejercieron un destacado prota…

Arte, coleccionismo y cultura nobiliaria en el Reino de València en tiempos de Felipe III

2022

El principal objetivo de la presente tesis doctoral es claro y conciso: analizar el coleccionismo artístico de la nobleza valenciana en tiempos de Felipe III. Es decir, del conjunto de prácticas aristocráticas que definían el ethos estamental -conductas y costumbres que diferenciaban la nobleza del pueblo llano-, se escoge una de ellas, la relativa al coleccionismo, para tratar de desentrañar su alcance en la configuración de la imagen del noble valenciano durante este marco temporal. De un modo paralelo, el acercamiento al modo de vida nobiliario y al estudio de sus bienes muebles ha incluido la consideración de hábitos no menos importantes, como las labores de mecenazgo artístico y patron…

Del Reino de Valencia a la Corte Imperial. La Casa de Castellnovo (1580-1730). El vuelo del pájaro celeste

2022

La presente tesis pretende abordar el proceso de ascenso social experimentado por la familia Cardona y Borja que, perteneciente a la élite valenciana, se convirtieron en marqueses de Castellnovo a mediados del siglo XVII. Partimos de la idea de que todo encumbramiento debe ser explicado desde la conjunción de factores de diversa índole y, por ello, nos adentramos en los principales personajes del linaje desde una perspectiva biográfica y microanálitica con el objeto de profundizar en los pormenores que hicieron posible su progresión, tanto en el escenario político-social como en el terreno económico y cultural. Siguiendo esta línea, prestamos una investigación dividida en cinco partes, en c…

El linaje valenciano de los Roig. Memoria, familia y patrimonio a través de quince generaciones

2017

Reconstruimos en este estudio el linaje de los Roig de València, y analizamos sus bases materiales, las estrategias de reproducción y sus relaciones sociales, familiares, de parentesco o económicas, con el hilo conductor del “libro de familia”, que inició en 1688 don Francisco Roig y Dou (1631-1692), en el que dejó a sus descendientes las noticias familiares de nueve generaciones desde el siglo XIV, y una detallada memoria sobre la gestión del patrimonio familiar. El libro fue continuado por sus descendientes hasta 1871, recogiendo hasta siete manos (siete generaciones), convirtiéndose así en uno de los más extensos e interesantes egodocumentos de la historiografía valenciana y europea. El …

A solar photothermo-catalytic combined process for the VOCs combustion and the subsequent CO2 valorization using noble metal-free catalysts

2023

We here investigated a solar photothermo-catalytic combined process where the toluene (as volatile organic compound model) was first oxidized to CO2 which was subsequently converted into solar fuels in a second reactor. For this aim two noble-metal free catalytic systems were used, namely MnOx-ZrO2, which gave the best results for the toluene removal, and brookite TiO2-CeO2 mixed oxides which were the most efficient in the subsequent CO2 conversion. This latter reaction was further improved by the addition of small amounts of copper-based materials on brookite-ceria, acting as co-catalysts. The key point for both the examined reactions was the synergism between the thermocatalytic and the p…
