From Single Molecules to Nanoscopically Structured Materials: Self-Assembly of Metal Chalcogenide/Metal Oxide Nanostructures Based on the Degree of P…
2011
A chemically specific and facile method for the immobilization of metal oxide nanoparticles onto the surface of IF-MoS2 nested fullerenes is reported. The modification strategy is based on the chalcophilic affinity of transition metals such as Fe2+/Fe3+, Fe3+, or Zn2+ as described by the Pearson HSAB concept. The binding capabilities of the 3d metals are dictated by their Pearson hardness. Pearson hard cations such as Fe3+ (Fe2O3) do not bind to the chalcogenide surfaces; borderline metals such as Fe2+ (Fe3O4) or Zn2+ (ZnO) bind reversibly. Pearson-soft metals like Au bind irreversibly. The immobilization of metal oxide nanoparticle colloids was monitored by transmission electron microscopy…

Eco-friendly cavity-containing iron oxides prepared by mild routes as very efficient catalysts for the total oxidation of VOCs
2018
Iron oxides (FeOx) are non-toxic, non-expensive and environmentally friendly compounds, which makes them good candidates for many industrial applications, among them catalysis. In the present article five catalysts based on FeOx were synthesized by mild routes: hydrothermal in subcritical and supercritical conditions (Fe-HT, Few200, Few450) and solvothermal (Fe-ST1 and Fe-ST2). The catalytic activity of these catalysts was studied for the total oxidation of toluene using very demanding conditions with high space velocities and including water and CO2 in the feed. The samples were characterized by X-ray diffraction (XRD), scanning and high-resolution transmission electron microscopy (SEM and…
Intervención en Libia: La responsabilidad de proteger a debate
2011
Resumen El trabajo analiza el origen y evolución del concepto de la responsabilidad de proteger, sus antecedentes en la década de los noventa del S. XX, su formulación en el Informe sobre La responsabilidad de proteger, y su consolidación posterior con especial atención al Documento Final de la Cumbre de 2005. Se examina asimismo el modo en que se ha aplicado esta norma emergente en la Resolución 1973 del Consejo de Seguridad, de 17 de marzo de 2011, que ha autorizado el uso de la fuerza en Libia. Y se concluye que casi todas las limitaciones y objeciones que se están planteando en relación con esta intervención, probablemente son consustanciales al modo en que actualmente se ponen en prác…
Ideas, conceptos y dilemas para la implementación de una plataforma nacional de ODR en materia de consumo en Chile desde la perspectiva UE
2019
En la presente tesis hemos desarrollado una extensiva investigación monográfica en busca del concepto de ODR (online dispute resolution), el cual se encuentra en un constante desarrollo en el quehacer jurídico procesal comparado, sobre todo en materia del derecho de consumidor en el espacio de integración de la Unión Europea, con el impulso otorgado a la materia por la directiva 2011/2013 EU y el Reglamento 534/2013 EU,y la consecuente transposición de dichas normas a las tradiciones jurídicas de los Estados miembros. La búsqueda para generar un marco jurídico cada vez más proclive al consumidor dentro del mercado único europeo, ha impulsado el desarrollo de la legislación comunitaria, y la…

Magistrinį darbą sudaro 63 puslapiai, 10 iliustracijų, 31 schema, 14 lentelių, 1 lygtis, 53 literatūros šaltiniai. Darbas parašytas anglų kalba. Pirmiausia buvo ištirta antrinių alkoholių racemizacija įvairių iridžio, rutenio ir geležies katalizatorių pagalba. Tuomet, racemizacijai tinkamiausiuose tirpiklių variantuose buvo tiriama alkoholių kinetinė rezoliucija. Gauti duomenys buvo panaudoti naujos dinaminės kinetinės rezoliucijos procedūros paieškose.
HIGH QUALITY TEXTURE MAPPING PROCESS AIMED AT THE OPTIMIZATION OF 3D STRUCTURED LIGHT MODELS
2019
Abstract. This article presents the evaluation of a pipeline to develop a high-quality texture mapping implementation which makes it possible to carry out a semantic high-quality 3D textured model. Due to geometric errors such as camera parameters or limited image resolution or varying environmental parameters, the calculation of a surface texture from 2D images could present several color errors. And, sometimes, it needs adjustments to the RGB or lightness information on a defined part of the texture. The texture mapping procedure is composed of mesh parameterization, mesh partitioning, mesh segmentation unwraps, UV map and projection of island, UV layout optimization, mesh packing and mes…
RPAS AND TLS TECNIQUES FOR ARCHAEOLOGICAL SURVEY: THE CASE STUDY OF THE ARCHAEOLOGICAL SITE OF ERACLEA MINOA (ITALY)
2018
Abstract. Digital documentation and 3D modelling of archaeological sites are important for understanding, definition and recognition of the values of the sites and of the archaeological finds. The most part of archaeological sites are outdoor location, but a cover to preserve the ruins protects often parts of the sites. The possibility to acquire data with different techniques and merge them by using a single reference system allows creating multi-parties models in which 3D representations of the individual objects can be inserted. The paper presents the results of a recent study carried out by Geomatics Laboratory of University of Palermo for the digital documentation and 3D modelling of E…
HIGH-RESOLUTION SURFACE AND BED TOPOGRAPHY MAPPING OF RUSSELL GLACIER (SW GREENLAND) USING UAV AND GPR
2020
Abstract. This study presents the detailed survey of the northern marginal part of Russell Glacier, SW Greenland using the combination of unmanned aerial vehicle (UAV) photogrammetry and low-frequency ground penetrating radar (GPR) measurements. Obtained digital elevation model (DEM) and ice thickness data from GPR data allowed the generation of high precision subglacial topography model. We report uncertainties arising from GPR, GPS, and DEM suggesting sufficient accuracy for the reconstruction of glacier bed topography. GPR data and generated subglacial topography model does not reveal any possible Nye channel that could be incised into the bedrock, however, we were able to detect englaci…
TERRESTRIAL LASER SCANNING FOR COASTAL GEOMORPHOLOGIC RESEARCH IN WESTERN GREECE
2012
We used terrestrial laser scanning (TLS) for (i) accurate volume estimations of dislocated boulders moved by high-energy impacts and for (ii) monitoring of annual coastal changes. In this contribution, we present three selected sites in Western Greece that were surveyed during a time span of four years (2008-2011). The Riegl LMS-Z420i laser scanner was used in combination with a precise DGPS system (Topcon HiPer Pro). Each scan position and a further target were recorded for georeferencing and merging of the point clouds. For the annual detection of changes, reference points for the base station of the DGPS system were marked. Our studies show that TLS is capable to accurately estimate volu…
