The main results of two decades of research on self-assembled clusters of microdroplets are reviewed, from the discovery of the phenomenon to current advances that can be applied to solve problems related to the airborne spread of dangerous pathogens and atmospheric pollutants. Special attention is paid to a flexible procedure for generating droplet clusters from a given number of nearly identical droplets of controlled chemical compositions with possible biological inclusions and effective ways of stabilizing the clusters. This is important for chemical and biological research in droplet microreactors. The physical mechanism of self-assembly of droplets in an ascending gas flow over a locally heated liquid layer is described in relation to the main methods of cluster stabilization: by infrared irradiation or by adding soluble but non-evaporating substances to a layer of evaporating liquid. The main module of a modern laboratory setup is presented.

Études Ricoeuriennes / Ricoeur Studies

Ce texte défend la thèse selon laquelle il y aurait plus d’un tournant herméneutique chez Ricœur. Il soutient que c’est en se rendant compte des apories liées à son premier tournant herméneutique, celui de 1960, que Ricœur s’est résolument tourné vers les questions et les défis de l’herméneutique, dans ce qui peut être compris comme un retournement de son premier tournant herméneutique. Ce tournant a par la suite pris d’autres formes chez Ricœur et sa philosophie en est devenue une des détours herméneutiques. On se demandera si la voie des détours est toujours la voie royale de l’herméneutique et on se penchera sur la dernière expression de ce tournant herméneutique à la fin de La mémoire, l’histoire, l’oubli.

This paper explores the tensions and potential contradictions in the "self-construction" of habits and preferences, arguing that preferences and tastes not only arise from habit formation but also contribute to the development of new habits. Changing tastes necessitates self-reflection on our current preferences and habits, which then become subjects of evaluation, transformation, and alteration from a higher-order perspective. It will be argued that modifying the structure of one's habits and preferences requires various forms of (self)-distancing: these include the impossibility of immediate transformation, recognizing the gradual nature of change, and acknowledging the limits of direct intentionality and control in the transformative process. These points ultimately reveal the inherent indeterminacy and openness of any self-cultivation endeavor involving preference-based habits, highlighting its balance between controllability and the potential for its loss.
