La posición constitucional del poder judicial
2010
En el Estado de Derecho, el poder judicial se posiciona a la par de los poderes legislativo y ejecutivo. Esto lo consigue a traves de su independencia. El articulo explica eso desde el punto de vista doctrinal y lo aplica al analisis de la regulacion en la materia en la Constitucion de Bolivia de 2009.

Nuova introduzione allo studio del diritto inglese. Le fonti
2016
Nella prefazione alla terza edizione, pubblicata nel 2000, alla Sua introduzione allo studio del diritto inglese l’Autore esprimeva un punto di vista risoluto e chiaro, consistente nella necessità della conoscenza del diritto inglese allo scopo di accrescere il dialogo tra i giuristi europei. E questo perché il riferimento al common law implica il rinvio a strutture di pensiero, a categorie giuridiche, a modelli normativi che comunque rappresentano esperienze originali e rilevanti nel continente europeo e possono orientare delicate scelte di politica del diritto in ambito comunitario: a tal proposito Giovanni Criscuoli ricordava come nel dibattito circa i possibili criteri di redazione dei …
Nuova introduzione al diritto inglese
2021
Il passaggio del tempo è già di per sé una ragione sufficiente per consigliare l’aggiornamento di un’opera attraverso la pubblicazione di una sua nuova edizione che contempli anche solo informazioni ed opinioni sopravvenute relative alla materia trattata. Il quinquennio trascorso da quando vide la luce la “Nuova introduzione allo studio del diritto inglese”, prosecuzione ideale e tematica dell’originaria fatica di Giovanni Criscuoli all’inizio del XXI secolo non è, tuttavia, la sola circostanza che mi ha indotto a curare e ad assumere la gravosa responsabilità della rinnovata edizione, sempre avvalendomi dell’indicazione con un asterisco delle parti da me direttamente redatte. Essa si è res…
Thermal gating of magnon exchange in magnetic multilayers with antiferromagnetic spacers
2020
We observe a strong thermally-controlled magnon-mediated interlayer coupling of two ferromagnetic layers via an antiferromagnetic spacer in spin-valve type trilayers. The effect manifests itself as a field-induced coherent switching of the two ferromagnets, which can be controlled by varying temperature and the spacer thickness. We explain the observed behavior as due to a strong hybridization of the ferro- and antiferro-magnetic magnon modes in the trilayer at temperatures just below the N\'eel temperature of the antiferromagnetic spacer.
Structure of the new mineral sarrabusite, Pb5CuCl4(SeO3)4, solved by manual electron-diffraction tomography.
2012
The new mineral sarrabusite Pb5CuCl4(SeO3)4 has been discovered in the Sardinian mine of Baccu Locci, near Villaputzu. It occurs as small lemon–yellow spherical aggregates of tabular crystals (< 10 µm) of less than 100 µm in diameter. The crystal structure has been solved from and refined against electron diffraction of a microcrystal. Data sets have been measured by both a manual and an automated version of the new electron-diffraction tomography technique combined with the precession of the electron beam. The sarrabusite structure is monoclinic and consists of (010) layers of straight chains formed by alternating edge-sharing CuO4Cl2 and PbO8 polyhedra parallel to the c axis, which sha…
La compleja configuración de un derecho-libertad poliédrico, el Derecho a la información. Referencias históricas
2017
ResumenEste estudio sobre la configuración del derecho a la información trata de poner de relieve las peculiaridades del mismo que explican que, por más que existan precedentes doctrinales bien lejanos, no haya podido constitucionalizarse en Europa hasta avanzado el siglo xx. Debiendo insistir en la necesidad de que no sea confundido con la libertad de expresión, muchas referencias que se hacen en perspectiva histórica tratan justamente de subrayar esa diferencia entre ambosderechos-libertades y por consiguiente se trata de negar que se pueda considerar información lo que solo es expresión. Si bien la mayor soleray maduración de la libertad de expresión tiende a absorver en si misma el dere…
"Ab initio" structure solution from electron diffraction data obtained by a combination of automated diffraction tomography and precession technique
2009
Using a combination of our recently developed automated diffraction tomography (ADT) module with precession electron technique (PED), quasi-kinematical 3D diffraction data sets of an inorganic salt (BaSO(4)) were collected. The lattice cell parameters and their orientation within the data sets were found automatically. The extracted intensities were used for "ab initio" structure analysis by direct methods. The data set covered almost the complete set of possible symmetrically equivalent reflections for an orthorhombic structure. The structure solution in one step delivered all heavy (Ba, S) as well as light atoms (O). Results of the structure solution using direct methods, charge flipping …
Elektrónová a pásová štruktúra CuMnAs študovaná optickou a fotoemissinou spektroskopiou
2017
Tetragonal phase of CuMnAs progressively appears as one of the key materials for antiferromagnetic spintronics due to efficient current-induced spin-orbit torques whose existence can be directly inferred from crystal symmetry. Theoretical understanding of spintronic phenomena in this material, however, relies on the detailed knowledge of electronic structure (band structure and corresponding wave functions) which has so far been tested only to a limited extent. We show that AC permittivity (obtained from ellipsometry) and UV photoelectron spectra agree with density functional calculations. Together with the x-ray diffraction and precession electron diffraction tomography, our analysis confi…
A multi-technique, micrometer- to atomic-scale description of a synthetic analogue of chukanovite, Fe-2(CO3)(OH)(2)
2014
International audience; A synthetic analogue of chukanovite Fe-2(CO3)(OH)(2) is formed during experimental work on iron-clay interactions simulating the cooling of containers in radioactive waste repositories. Despite its small size and the mixture with other minerals it is undoubtedly identified by X-Ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy and Transmission Electron Microscopy. For the first time, the structural characterisation of a synthetic chukanovite is carried out thanks to the combination of Automated Diffraction Tomography and Precession Electron Diffraction. Refinement results and comparison with literature data show that the structure…
