Preparation of transparent and superhydrophobic coatings by co-deposition of an aqueous solution of an amphiphilic fluorinated block copolymer (FBC) with silica particles was developped. Spin- coating of this aqueous solution onto glass followed by an appropriate thermal treatment promotes the self-assembly of the hybrid material with the formation of superhydrophobic, robust and transparent coatings.

Comtesse puis duchesse d’Angoulême, Louise de Savoie (1476-1531) est l’une des personnalités les plus influentes de la première Modernité européenne. Elle n’est pas seulement la mère de deux enfants illustres, Marguerite, future reine de Navarre, et François, futur François Ier, elle est aussi la sœur de Philibert II le Beau, duc de Savoie. Une fois son fils monté sur le trône de France, Louise domine le Conseil et assure, à deux reprises, la régence du royaume. Son action concerne encore les arts et les lettres : amatrice d’objets d’art et bibliophile avertie, elle demande à Léonard de Vinci d’imaginer une ville et un palais neuf à Romorantin, participant de la sorte à la diffusion en France des idées et des formes venues d’Italie. Curieusement, alors que son influence fut considérable, Louise de Savoie n’a pas fait l’objet d’une monographie récente (un ouvrage collectif à son propos paraîtra toutefois en 2015). Son emblématique n’a plus été analysé depuis les travaux d’Anne-Marie Lecocq (1987), qui s’était essentiellement concentrée sur les signes présents dans les livres qu’elle commanda pour soutenir l’éducation de ses enfants. À l’occasion de cette communication – prolongeant ainsi une recherche entreprise avec Pierre-Gilles Girault – nous voudrions revenir sur le discours héraldique de Louise de Savoie, en explicitant l’une de ses devises favorites, la cordelière. Pour la mère de François Ier, la corde à plusieurs nœuds revêt plusieurs significations. D’abord, puisqu’elle se compose de nœuds de Savoie, un emblème largement diffusé au début du XVIe siècle, notamment sous l’influence de Philibert II le Beau et Marguerite d’Autriche, elle souligne l’appartenance de la dame à la maison de Savoie. Ensuite, et ce de façon inédite au sein de la maison de Savoie, la cordelière de Louise associe nœuds de Savoie et cordon franciscain, une référence que nous proposons d’expliquer non pas uniquement, comme on le fait traditionnellement, par les liens prétenduement étroits qui reliaient la mère de François Ier avec l’ordre des Franciscains. Pour Louise, il s’agit sans doute aussi de se situer dans la lignée d’Anne de Bretagne, à laquelle la cordelière est indéniablement liée. [less ▲]

A l'occasion de cette étude, à la suite des travaux d'Anne-Marie Lecoq (1987), nous sommes revenus sur le discours héraldique de la comtesse et duchesse d'Angoulême, Louise de Savoie, l'influente mère de François Ier. Nous avons présenté et explicité ses devises favorites, à savoir la cordelière, qui évoque autant le nœud de Savoie que la cordelière franciscaine, le vol, sans doute choisi puisque l’aile évoque le L de Louise par homophonie, le bouquet de lis ou le cygne « navré », mais aussi les écus et les monogrammes qui lui sont associés et qui ponctuent enluminures, tapisseries, bas-reliefs et éléments sculptés de l’architecture. Notre intention a été de montrer d’une part comment Louise de Savoie manifeste, par l’intermédiaire de ces signes emblématiques, son identité et son pouvoir, d’autre part comment elle construit, par leur biais, un patrimoine, mental, susceptible de renforcer son clan et ses héritiers.

iving/controlled polymerization methods have enabled the synthesis of numerous (co)polymers with defined compositions and architectures. However, the precision design of poly(vinylamine)-based copolymers remains challenging despite their extensive use in various fields of applications and the clear benefits to finely tune their properties. Here, we report on a two-step strategy for the synthesis of tailor-made poly(vinylamine) derivatives through the organometallic- mediated radical (co)polymerization (OMRP) of N-vinyl- acetamide and/or N-methylvinylacetamide followed by acid hydrolysis of the acetamide groups. A series of well-defined homopolymers as well as statistical and block copolymers with pendant primary and/or secondary amines having controlled molar masses, compositions, and low dispersities were produced accordingly. The reactivity ratios of the comonomers as well as the composition drift along the chain were determined in order to have a precise idea of the polymer structures. These advances represent a significant step toward an efficient platform for synthesis of this important class of amino group-containing (co)polymers. [less ▲]

Three Earth-sized exoplanets were recently discovered close to the habitable zone of the nearby ultracool dwarf star TRAPPIST-1. The nature of these planets has yet to be determined, since their masses remain unmeasured and no observational constraint is available for the planetary population surrounding ultracool dwarfs, of which the TRAPPIST-1 planets are the first transiting example. Theoretical predictions span the entire atmospheric range from depleted to extended hydrogen-dominated atmospheres. Here, we report a space-based measurement of the combined transmission spectrum of the two inner planets made possible by a favorable alignment resulting in their simultaneous transits on 04 May 2016. The lack of features in the combined spectrum rules out cloud-free hydrogen-dominated atmospheres for each planet at 10-$\sigma$ levels; TRAPPIST-1 b and c are hence unlikely to harbor an extended gas envelope as they lie in a region of parameter space where high-altitude cloud/haze formation is not expected to be significant for hydrogen-dominated atmospheres. Many denser atmospheres remain consistent with the featureless transmission spectrum---from a cloud-free water vapour atmosphere to a Venus-like atmosphere. [less ▲]

Notre objectif est de discuter des diagnostics du fonctionnement psychologique pervers et de la personnalité psychopathique. Si les versions récentes du DSM (IV et 5) ignorent ces diagnostics, la pratique clinique suggère de conserver ces deux entités présentant une finesse psychopathologique plus grande et un pouvoir discriminatif plus important que la personnalité antisociale. Nous souhaitons interroger les dimensions intrinsèquement adaptatives de ces deux entités, mais aussi relever leurs différences sur le continuum de l’adaptation. Nous chercherons, en effet, à démontrer que le principe d'adaptation est une dimension centrale et commune aux deux entités, mais qui « se joue » de façons différentes pour chacune. Le pervers est hyper-adapté à son interlocuteur tout en présentant des moments paradoxaux d'inadaptation. Le psychopathe, avec sa faculté de chosification de l'alter ego et ses compétences émotionnelles paradoxales, présente une adaptation plus solitaire. Dans une perspective inspirée des paradigmes éthologique et phénoménologique, nous tenterons de cerner les différences essentielles entre ces deux modes d’être-au-monde. [less ▲]

Ball bearings have been used for a long time. Nevertheless, the description of their behavior remains incomplete in spite of the large number of surveys dedicated to ball bearings. Particularly, the exact balls kinematics has still to be addressed in depth. This paper proposes a new way to calculate the balls kinematics by using a simplified quasi-static approach for dry lubricated and axially loaded ball bearings. This method does not use the classical restrictive race control assumptions. More specifically, the role played by the balls kinematics is emphasized by means of the power dissipated within contacts between balls and races. The need for a correct evaluation of the balls behavior is illustrated by using an example, viz. a ball bearing of cryogenic engine turbopump. Indeed, the dissipated power is one of the main concerns in this particular case. [less ▲]

Many significant intellectual developments have taken place in 20th century European social theories. Notably the first Frankfurt School and Bourdieu’s work have successfully shown how workers, social actors, etc. are alienated or dominated by capitalist social structures. But according to Habermas, neither perspective successfully allows for the possibility that people could contribute to their own emancipation. The emergence of new forms of social resistance to domination such as those embodied by the Indignados, Anonymous, Femen, the practitioners of alternative economy, movements of unemployed people or illegals compels us to envisage the possibility for emancipation, but how? In this paper we explore opportunities for accounting for this by considering the work of a range of other European social theorists, more specifically Boltanski whose critical intent is embodied in his pragmatic sociology, and evident in his coining and use of the concept of the world. In addition we will consider Latour’s own pragmatic stance as we believe that despite his disinterest in new social movements, his work, informed by pure immanence, might offer potential solutions. But we would argue that even in these innovations there is either a persistent tendency to imagine emancipation primarily as a return to some ideal state or a lack of critical engagement with alienation. In response, we propose a materialist renewal, which will lead us to ponder on the political role of sociologists. [less ▲]

From Marx to Althusser, the materialist approach has tended to assume that individuals (that is, workers, proletarians and other social actors), unconsciously reproduce the social structures of capitalism which alienate them. It is assumed that individuals accept the conditions forced upon them and no longer seek to rebel against a world which substantially impoverishes their labour, their spirit and their creativity. In this paper, I will try to show that by dint of favouring almost exclusively Marx's concept of alienation, there is a considerable risk that materialist thought will adopt only a negative path. Whilst I acknowledge Marx’s significance to materialism, I wish to argue that his stance should be combined with that of the anarchist and libertarian French thinker Proudhon. Proudhon has succeeded in presenting a conception of the worker as more than just alienated. Workers can also cooperate and experience a reciprocity seemingly at odds with the character of capitalism. Under Proudhon’s influence materialism takes a positive turn, enabling us to avoid falling into the utopianism that the theory of social economy employs to critique capitalism – a utopianism that renders its critique even less effective than that of Marx.
