Selective CO 2 Sorption Using Compartmentalized Coordination Polymers with Discrete Voids**

2021

Carbon capture and storage with porous materials is one of the most promising technologies to minimize CO2 release into the atmosphere. Here, we report a family of compartmentalized coordination polymers (CCPs) capable of capturing gas molecules in a selective manner based on two novel tetrazole-based ligands. Crystal structures have been modelled theoretically under the Density Functional Theory (DFT) revealing the presence of discrete voids of 380 A3 . Single gas adsorption isotherms of N2 , CH4 and CO2 have been measured, obtaining a loading capacity of 0.6, 1.7 and 2.2 molecules/void at 10 bar and at 298 K for the best performing material. Moreover, they present excellent selectivity an…

Oxo and Hydroxo Tantalocene Complexes:  Synthesis and Reactivity. X-ray Molecular Structures of [(η5-Cp*)TaCl(OH)(η5-C5H4SiMe3)]+Cl-, (η5-Cp*)TaCl(O)…

2005

Exposure of a THF solution of tantalocene dichloride complexes (η 5 -Cp*)TaCl 2 (η 5 -C 5 H 4 -SiMe 3 ) (1) and (η 5 -Cp*)TaCl 2 (η 5 -C 5 H 5 ) (2) to the ambient atmosphere for 12 h leads to the formation of new tantalum(V) cationic hydroxo complexes [(η 5 -Cp*)TaCl(OH)(η 5 -C 5 H 4 SiMe 3 )] + -Cl- (3) and [(η 5 -Cp*)TaCl(OH)(η 5 -C 5 H 5 )]+Cl - (4). This oxidation reaction is more rapid under oxygen atmosphere since the hydroxo complexes are obtained in better yields within only 15 min. The hydroxo complexes are easily deprotonated by base to generate oxo complexes 5 and 6, which, in turn, react with trimethylsilyl triflate, giving the corresponding cationic silylated complexes 7 and 8…

L’educazione familiare e il consumo del cinema negli anni Cinquanta tra Nord e Sud d’Italia

2017

In questo articolo, il cinema degli anni Cinquanta viene indagato come mezzo di consumo e come strumento di socializzazione delle masse italiane, in un confronto tra il Nord industrializzato e il Sud ancora prevalentemente agricolo, ma anche tra le zone urbane e quelle rurali, tra classi e tra generi differenti. Seguendo la storia del cinema italiano nel «decennio più lungo del secolo breve», dal neorealismo al melò alla commedia, emerge che il cinema entrava nella vita delle famiglie italiane plasmandole, ridisegnando identità e costruendo nuovi immaginari. Nonostante il diverso approccio con cui le famiglie italiane andavano al cinema, questo fu vissuto come una fonte di istruzione che co…

Cambios en el comercio exterior de los países del este. La difícil reinserción en Europa

1999

Changes in the foreign trade of the countries of the East. The difficult assimilation into Europe. The direction of the trading lines of the post-communist countries has been modified by the political and economical changes of the countries of the East of Europe, the dismantling of the COMECON, as well as by the disintegration of the USSR and the detente in the international relationships. During the forty years that the COMECON was prevailing, that region centred its attention on the USSR, but nowadays the East looiks at the West, concretaly at the European Union and more exactly at Germany. The composition of the imports and exports reveals the marked dependence on Central and Eastern Eur…

The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…

2019

The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…

Más allá de Marx: postobrerismo y posmarxismo. Una revisión de los fundamentos teóricos de la multitud y el pueblo

2018

The article is a synthetic essay that exposes the main theoretical lines of the postmarxist approach of Laclau and Mouffe, on the one hand, and the autonomist post-operaism of Negri, Hardt, Virno, etc., on the other hand. These theories are conceived as attempts to rationalize current political bets by various political sectors and social movements. It analyzes both argumentative strategies from «orthodox» Marxism and the structure / superstructure relationship; and the forms of constitution of new subjectivities. It compares the theoretical fundamentals of hegemonic articulations and counter-power experiences. It discusses, likewise, the scope and limitations of the categories of «people» …
