Dimensional encapsulation of I− I 2 I− in an organic salt crystal matrix
2010
Bis(trimethylammonium)hexane diiodide encapsulates iodine from solution and through a gas/solid reaction yielding in a predictable and controllable manner the selective formation of the rare polyiodide species I(-)...I-I...I(-), which matches in length to the chosen dication.
Hydrogen Bonding in Amorphous Alkaline Earth Carbonates
2018
Amorphous intermediates play a crucial role during the crystallization of alkaline earth carbonates. We synthesized amorphous carbonates of magnesium, calcium, strontium, and barium from methanolic solution. The local environment of water and the strength of hydrogen bonding in these hydrated modifications were probed with Fourier transform IR spectroscopy,
Intelaiature lignee leggere quale presidio antisismico nell'architettura tradizionale di area mediterranea
2017
L’accresciuta attenzione nei confronti degli aspetti costruttivi dell’edificato storico, associata all’analisi delle tecniche attraverso la ricerca archivistica, ma ancor più gli interventi di restauro e recupero che punteggiano i centri storici per iniziativa pubblica e privata consentono di ritrovare -nascoste anche all’occhio attento che le sa riconoscere- le intelaiature a graticcio ligneo: teatri ad intera struttura lignea, la configurazione interna di saloni ed ambienti di rappresentanza di palazzi nobiliari, chiese, conventi o monasteri ed anche l’edilizia diffusa che definiremmo “di base” testimoniano la capillare applica-zione del sistema costruttivo, con invarianti ed originalità …
Algunas consideraciones bioéticas y jurídicas acerca de la Declaración de Ginebra sobre edición del genoma humano hereditario a la vista de las Decla…
2021
[ES] La reciente Declaración de Ginebra sobre edición del genoma humano denuncia la posición central que han ocupado tanto la Ciencia como la Bioética hasta la fecha, afirmando que ambas mantienen una posición decididamente favorable respecto a esta bioingeniería, y todo lo cual pone de manifiesto la acuciante necesidad de reorientar el debate hacia el campo del Derecho. El presente artículo tiene por objeto analizar pormenorizadamente las consideraciones vertidas en este documento, formulando interrogantes sobre algunas de ellas, y poniendo en valor la conveniencia de articular un consenso multidisciplinar encabezado por los derechos humanos, en particular, de aquellos grupos más vulnerabl…
Solidarity in games with a coalition structure
2010
Abstract A new axiomatic characterization of the two-step Shapley value Kamijo (2009) is presented based on a solidarity principle of the members of any union: when the game changes due to the addition or deletion of players outside the union, all members of the union will share the same gains/losses.
Solid‐state NMR Spectroscopy of Iodine(I) Complexes
2023
Solid-state NMR has been applied to a series of Barluenga-type iodine(I) [L-I-L]PF6 (L=pyridine, 4-ethylpyridine, 4-dimethylaminopyridine, isoquinoline) complexes as their hexafluorophosphate salts, as well as their respective non-liquid ligands (L), their precursor silver(I) complexes, and the respective N-methylated pyridinium and quinolinium hexafluorophoshate salts. These results are compared and contrasted to the corresponding solution studies and single-crystal X-ray structures. As the first study of its kind on the solid-state NMR behavior of halogen(I) complexes, practical considerations are also discussed to encourage wider utilization of this technique in the future. peerReviewed
The solid-state hierarchy and iodination potential of [bis(3-acetaminopyridine)iodine(I)]PF6
2022
The first iodine(I) complex bearing hydrogen-bond donor and acceptor groups, [bis(3-acetaminopyridine)iodine(I)]PF6 (3), was synthesised, which exhibited two temperature-dependent solid-state connectivities of the hydrogen bonding. Upon reaction of 3 with tBuOMe, unprecedented iodination of a tBu methyl group proceeded under exceptionally mild conditions in good yield. peerReviewed
Up with ecology, down with economy? : The consolidation of the idea of climate change mitigation in the global public sphere
2018
Building on theories of valuation and evaluation, we develop an analytical framework that outlines six elements of the process of consolidation of an idea in the public sphere. We then use the framework to analyse the process of consolidation of the idea of climate change mitigation between 1997 and 2013, focusing on the interplay between ecological and economic evaluations. Our content analysis of 1274 articles in leading newspapers in five countries around the globe shows that (1) ecological arguments increase over time, (2) economic arguments decrease over time, (3) the visibility of environmental nongovernmental organizations as carriers of ecological ideas increases over time, (4) the …
Occurrence of pharmaceuticals in municipal wastewater treatment plants and receiving surface waters in Central and Southern Finland
2016
The presence of five selected pharmaceuticals, four anti-inflammatory drugs, diclofenac, ibuprofen, ketoprofen, naproxen, and an antiepileptic drug carbamazepine, was determined at four municipal wastewater treatment plants (WWTPs) and in the receiving waterway near the city of Jyväskylä, in central Finland and also in the River Vantaa. First, an analytical method was developed including a pretreatment and purification followed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) in the multiple reaction monitoring mode. The studied pharmaceuticals were detected from influents and effluents of four municipal WWTPs and from surface water of eight locations along the water …
