Chemistry – A European Journal, Volume 28, Issue 70, December 15, 2022., 2022 Cyanopyridines are reduced at low potentials in organic solvents and are therefore a promising class of molecules for anolytes for nonaqueous redox‐flow batteries (RFBs). Quantum computations suggest that properly placed phenyl and methyl substituents shift the reduction potentials even lower than those of the parent cyanopyridines and prevent ...

Kosovo-Spain Relations and the Dilemmas on the Problem of Non-Recognition
SEEU Review, 2019 Eleven years after Kosovo’s unilateral declaration of independence, Spain’s position vis-à-vis Kosovo has not only not varied, but it has become stronger, turning Madrid into the leader of the Kosovo non recognizers club within the EU.

Casimir energy and the superconducting phase transition [PDF]
J.Phys.A39:6161-6171,2006, 2006 We study the influence of Casimir energy on the critical field of a superconducting film, and we show that by this means it might be possible to directly measure, for the first time, the variation of Casimir energy that accompanies the superconducting transition.

Privileged Rebels: A Longitudinal Analysis of Distinctive Economic Traits of Catalonian Secessionism
Genealogy, 2020 During the last decade, the Catalonian secessionist challenge induced a chronic crisis within Spain’s politics that does not offer hints of a viable arrangement.

Canonical Noether symmetries and commutativity properties for gauge systems [PDF]
J.Math.Phys. 41 (2000) 7333-7351, 2000 For a dynamical system defined by a singular Lagrangian, canonical Noether symmetries are characterized in terms of their commutation relations with the evolution operators of Lagrangian and Hamiltonian formalisms. Separate characterizations are given in phase space, in velocity space, and through an evolution operator that links both spaces.

Fibre derivatives: some applications to singular lagrangians [PDF]
Rept.Math.Phys. 45 (2000) 67-84, 2000 The fibre derivative of a bundle map is studied in detail. In the particular case of a real function, several constructions useful to study singular lagrangians are presented. Some applications are given; in particular, a geometric construction useful to solve the Euler-Lagrange equation of a singular lagrangian.

The Relevance of Language as a Predictor of the Will for Independence in Catalonia in 1996 and 2020
Politics and Governance, 2021 The Catalan secessionist parties, if added together, have won all the elections to the Parliament of Catalonia from 2010 to 2021. Their voters have been increasingly mobilized since the start of the controversial reform process of the Statute of Autonomy
