EPJ E - Gems for polymer scientists

EPJ E - Gems for polymer scientists

Tiny polymer droplets that crystallize on a surface are a shrewd expedient to study the birth of a polymer crystal by the elusive homogeneous nucleation mechanism. In most cases, take for example the dust particle in a snowflake, nucleation starts from a heterogenous defect. Homogenous nucleation is difficult to study because of the prevalence of defects in any bulk sample. Crystallization in small droplets alleviates this difficulty in a manner that is conceptually simple: subdivide the system into more domains than the number of defects. If the domains greatly outnumber the defects then only the homogenous mechanism can induce nucleation in a defect free compartment.

Jean-Marc Di Meglio becomes Editor in Chief of EPJ E

We are very pleased to announce that Jean-Marc Di Meglio, Physics Professor at the University Paris Diderot, has been appointed Editor in Chief of EPJ E, with the special title of Commissioning Editor in Chief. From 1981 to 1994 he worked in the laboratory of Pierre-Gilles de Gennes at College de France, and was Professor at the University of Strasbourg from 1994 to 2002 The European Physical Journal E has benefitted from his editorial talent and vast expertise since 2007, when he joined the Editorial Board of the journal. Professor Di Meglio's work ranges from soap films to bubbles, polymers, colloids and vesicles. His latest interest is in biomechanics. Professor Di Meglio will work alongside Editors in Chief Daan Frenkel and Frank Julicher. We wish him a great experience in his new role.

EPJ E - How the fruit fly got its spots

EPJ E - How the fruit fly got its spots

The eye of the Drosophila (fruit fly) is characterized by a neat hexagonal patterns, a fascinating system to study pattern formation in biology. A recent paper published in EPJ E proposes a new mechanism to explain the emergence of this pattern.

Daan Frenkel wins Soft Matter and Biological Physics Award

Professor Daan Frenkel (Cambridge University), Editor in Chief of EPJ E is the 2010 recipient of the Soft Matter and Biological Physics award for his contributions to the development and application of computational methods that have transformed our understanding of soft and biomolecular materials.

The Royal Society of Chemistry established this award in 2008. The award will be officially presented to Daan Frenkel in spring 2011. The publishers and the EPJ E journal team congratulate Daan Frenkel on this prestigious achievement.

EPJ E - Bendy interfaces

Bendy interfaces

The shape of the interface between two fluids can be controlled by changing the refractive index contrast between the fluids, researcher from the Universite Bordeaux have shown. Optofluidics are methods based on the combination of optics and fluidics which have recently promoted innovative approaches to manipulate liquid interfaces. Since flows are optically driven, researchers call this emerging field optohydrodynamics. The recent paper published in EPJ E presents a fine example of optohydrodynamic actuation at the microscopic scale, based on experimental and predictive numerical results. This work illustrates one of the simplest manifestations of optohydrodynamics and provides a frame to anticipate further developments of contactless interface micromanipulation by lasers.

EPJ E - Pierre-Gilles De Gennes Lecture Prize

Sam Safran

This July, during the International Soft Matter Conference 2010 in Granada, Spain, Professor Sam Safran will give the EPJ E - Pierre Gilles De Gennes lecture, associated with a prize given by the publishers of EPJ.
This is the first edition of the *EPJE - Pierre-Gilles De Gennes Lecture Prize*, which takes the name from the illustrious Nobel laureate who founded EPJ E.
The Editors in Chief elected Prof. Sam Safran of the Weizman Instutite, Israel, as the prize recipient to acknowledge his leading research in soft matter and biological physics. The prize was also endorsed by the ISMC 2010 conference committee.
The prize will be presented to Prof. Sam Safram by Prof. Dominique Langevin (who is an Associate Editor of EPJ E) at the beginning of his plenary talk, 6 July at 8.30 am.

Liquid crystals straighten up

Grazing incidence X-ray diffraction, performed by Grelet and colleagues, reveals that thin films of discotic liquid crystals typically prefer to lie flat in columns oriented along the surface of their substrate. These materials are potentially useful for organic solar cells, but to achieve good performance from such devices, the column axis should rather be oriented vertical to the conducting substrate. However, the authors of this EPJ E paper have discovered a specific thermal process that makes it possible to change the column alignment from planar to vertical and achieve the best conditions for charge transport in photovoltaic devices.
