CONFERENCE OBJECTIVES
- The main objective of the Conference is to report and exchange ideas for the fundamental understanding of the physics of droplets (production, transport, coating and stock), from the microscopic scale to the macroscopic world.
The following topics will be addressed:
- formation, transport and manipulation of a droplet: physical properties and study of fluid flows in a droplet.
- coating and protection of a droplet.
- applications and devices for microfluidics.
Each topic will be tackled from a basic standpoint and will also consider the possible emerging applications.
The Conference calls for presentations (oral and poster) on single specifically engineered droplets (down to micro and nano scale) and on large quantity droplets production up to emulsions.
The meeting will provide an opportunity to develop collaborations of European scientists active in the field with and within the specific industry.
Reports on practical applications in industry, such as: pharmacology, lab-on-a-chip technology, detergents, food industry, coating industry, are strongly encouraged and welcome.
The SCIENTIFIC PROGRAMME will be organized by Working Groups, which interact to each other in plenary, sequential sessions dedicated, respectively to:
- Formation, transport and manipulation of a droplet: deformation and dynamics of moving and impacting droplets approached from theoretical and numerical points of view; liquid flow inside the droplet - relevant to any application, especially for the mixing of droplets; modelling of micro-flows to understand the droplet interaction with its environment; methods and means to transport and manipulate the liquid droplet; specific surfaces elaborated considering the wetting properties of the droplets and the adhesion of the liquid onto a surface; ‘droplet handling’ topic consisting of tools such as optical wrenches that are able to change the shape of the droplet, to introduce another liquid in the droplet, to divide a droplet into smaller entities.
- Coating and protecting droplets: encapsulating by controlling the external layers around the droplet core; protected droplets handling and lifetime measuring; droplets behaviour in emulsions; development of a general theory of droplets coating using liquids with or without surfactants.
- Applications and devices: devices built on the bases of the collision of droplets; the control of the mixing of two droplets of different liquids; the coalescence of a droplet with another liquid; the exchange dynamics with fluid surrounding the droplet.
The Conference addresses to basic research physicists, chemists, engineers working on droplets, micro-droplets and nano-droplets physics and applications, young scientists and PhD students, specialized pharma-industry, SMEs.

Address: Avenue Louise 149, 1050 Brussels, Belgium
COST – European Cooperation in Science and Technology is one of the longest-running European instruments supporting cooperation among scientists and researchers across Europe. COST is also the first and widest European intergovernmental network for coordination of nationally funded research activities. COST mission is to strengthen Europe in scientific and technical research through the support of European cooperation and interaction between European Researchers. COST has 34 member countries plus one cooperating state (Israël) and enables scientists to collaborate in a wide spectrum of activities grouped under nine key scientific Domains. Ease of access for institutions from non-member countries also makes COST a very interesting and successful tool for tackling topics of a truly global nature.
COST has proven to be a flexible and significant research networking tool that in recent years (since 2005) has been extended to include support of scientists from Near Neighbour countries (Balkan countries, Mediterranean countries and NIS countries - Albania, Algeria, Armenia, Azerbaijan, Belarus, Bosnia and Herzegovina, Egypt, Georgia, Lebanon, Lybia, Moldova, Morocco, The Palestinian Authority, Russian Federation, Syria, Tunisia, Ukraine).
