A Metal-Polymer Interface Study using Electropolymerized Acrylonitrile on Nickel Surfaces

Studies of the interface between mineral and organic materials have been realized for a couple formed between pure transition metal and a polar and polarizable molecule (acrylonitrile). The results presented show the effects of a local electric field on the activation processes associated with adsorption sites and the molecule, interaction mechanisms and the resulting types of chemical bond. The structural, electronic and chemical properties of a nickel-polyacrylonitrile interface are described. Molecular and energetic qualitative models for the interaction mechanisms are proposed

Pierre Manent: The Empire of Modernity and the Church’s Response

Manent’s body of work often problematizes the modern conservative impulse to draw on the history of thought with modernity’s conception of history, and this essay will attempt to explain this dynamic. To do this, I will explain the basics of Manent’s account of modernity as a way of evaluating history, drawing on the work of other political philosophers to supplement Manent’s account. Then I will examine how the work of Manent and Emile Perreau-Saussine, with the Catholic response to the Enlightenment, can contribute to the Church’s strategy to engage with the puzzle of modernity.

Classical Singularities In Chaotic Atom-Surface Scattering

In this paper we show that the diffraction condition for the scattering of atoms from surfaces leads to the appearance of a distinct type of classical singularity. Moreover, it is also shown that the onset of classical trapping or classical chaos is closely related to the bifurcation set of the diffraction-order function around the surface points presenting the rainbow effect. As an illustration of this dynamic, application to the scattering of He atoms by the stepped Cu(115) surface is presented using both a hard corrugated one-dimensional wall and a soft corrugated Morse potential

Kardinaal Dubois door Hyacinthe Rigaud (1723) : een insider's view op een bibliotheek van de macht in de Grand Siècle

Cardinal Guillaume Dubois (1656-1723) rose to the apex of political and ecclesiastical power in Old Regime France. As Prime Minister, Archbishop and Cardinal, he played a decisive role in the consolidation of the peace treaties of Utrecht, Rastatt and Baden, ending the bloody 17th century. Hyacinthe Rigaud, the most famous of French portrait painters, portrayed him with all symbols of his dual dignity. Four books stand out as repositories of legitimacy, including legal works. An analysis of the catalog of Dubois’ opulent personal library indicates that the cardinal and Prime Minister owned thousands of legal works. Rigaud’s use of the volumes is no coincidence

Polish Catholic Bishops, Nationalism and Liberal Democracy

UIDB/04627/2020 UIDP/04627/2020The alliance of the Polish Catholic Church with the Law and Justice (PiS) government has been widely reported, and resulted in significant benefits for the church. However, beginning in mid-2016, the top church leadership, including the Episcopal Conference, has distanced itself from the government, and condemned its use of National Catholicism as a legitimation rhetoric for the government’s malpractices in the fields of human rights and democracy. How to account for this behavior? The article proposes two explanations. The first is that the alliance of the PiS with the nationalist wing of the church, while legitimating its illiberal refugee policy and attacks on democratic institutions of the government, further radicalized the National Catholic faction of the Polish church and motivated a reaction of the liberal and mainstream conservative prelates. The leaders of the Episcopate, facing an empowered and radical National Catholic faction, pushed back with a doctrinal clarification of Catholic orthodoxy. The second explanatory path considers the transnational influence of Catholicism, in particular of Pope Francis’ intervention in favor of refugee rights as prompting the mainstream bishops to reestablish the Catholic orthodoxy. The article starts by tracing the opposition of the Bishops Conference and liberal prelates to the government’s refugee and autocratizing policies. Second, it describes the dynamics of the church’s internal polarization during the PiS government. Third, it traces and contextualizes the intervention of Pope Francis during the asylum political crisis (2015-6). Fourth, it portrays their respective impact: while the pope´s intervention triggered the bishops’ response, the deepening rifts between liberal and nationalist factions of Polish Catholicism are the ground cause for the reaction.publishersversionpublishe
