New methods for creating 3D nanostructures deposited on an array of regularly spaced indentations on the surface of silicon films opens the door for innovative nanosensors
Scientists have shown that it is now possible to simultaneously create highly reproductive three-dimensional silicon oxide nanodots on micrometric scale silicon films in only a few seconds. Xavier Landreau and his colleagues at the University of Limoges, France, demonstrated in their paper published in EPJ D that they were able to create a square array of such nanodots, using regularly spaced nanoindents on the deposition layer, that could ultimately find applications as biosensors for genomics or bio-diagnostics.

Study quantifies effects of electric field-induced versus conventional heating
The effect of microwave heating and cell phone radiation on sample material is no different than a temperature increase, according to scientists from the Department of Chemistry and Biochemistry, Arizona State University, in Tempe, as published in a recent issue of EPJ B.

The publishers of The European Physical Journal C – Particles and Fields are pleased to announce the appointment of Professors Gino Isidori (Frascati) and Sergei Odintsov (Barcelona) as new theory Editors-in-Chief. This follows the splitting of the theory section into Theory I: Phenomenology of the Standard Model and Beyond, now led by Gino Isidori, and Theory II: Gravitation, Astroparticle Physics and Cosmology, General Aspects of Quantum Field Theories and Alternatives, now led by Sergei Odintsov.

How nickel-titanium nanometric-size particles change back to their memorised shape
University of Constance physicists Daniel Mutter and Peter Nielaba have visualised changes in shape memory materials down to the nanometric scale in an article published in EPJB.EPJ D - Not one, not two, not three, but four clones!

First quantum cloning machine to produce four copies
Xi-Jun Ren and Yang Xiang from Henan Universities in China, in collaboration with Heng Fan at the Institute of Physics of the Chinese Academy of Sciences, have produced a theory for a quantum cloning machine able to produce several copies of the state of a particle at atomic or sub-atomic scale, or quantum state, in an article published in EPJ D. This could have implications for quantum information processing methods used, for example, in message encryption systems.EPJ E - How biological capsules respond under stress

Innovative high-precision measuring tool to assess the bending elasticity of liposomes
Cosmetics and pharmaceutical drug delivery systems could be improved thanks to a new method developed to precisely measure the capability of capsule-like biological membranes to change shape under external stress. This work is outlined in a study published in EPJE by Philippe Méléard and Tanja Pott from the Rennes-based Institute of Chemical Sciences at the European University of Brittany and their colleagues from the Center for Biomembrane Physics at the University of Southern Denmark in Odense.EPJ E - How do protein binding sites stay dry in water?

- Published on 10 August 2012
In a report that has just been published in EPJE, researchers from the National University of the South in Bahía Blanca, Argentina studied the condition for model cavity and tunnel structures resembling the binding sites of proteins to stay dry without losing their ability to react, a prerequisite for proteins to establish stable interactions with other proteins in water.

Scientists examine the flow of liquid at the contact between randomly rough surfaces
A team of scientists from Italy and Germany has recently developed a model to predict the friction occurring when a rough surface in wet conditions (such as a road on a rainy day) is in sliding contact with a rubber material (such as a car tire tread block) in an article that has just been published in EPJE.EPJ A - The Similarity Renormalization Group for Three-Body Interactions in One Dimension
- Details
- Published on 10 August 2012
One important message that has emerged from developments of effective field theories and effective Hamiltonians for nuclear physics is that many-body forces are inevitable whenever degrees of freedom are eliminated. At the same time, first-principles calculations have shown that two-body forces alone are not able to give an accurate account of the energies of light nuclei and the saturation of nuclear matter. Three- (and possibly more-) body forces are thus essential in low-energy nuclear physics.

Most stringent limits ever set by ATLAS
"Supersymmetry - to be or not to be?" remains a still unanswered question - it is a traditionally difficult business to demonstrate a zero result in experimental physics - yet the ATLAS collaboration has just set new and very stringent limitations on the "viability space" of a class of new physics models incorporating gauge-mediated supersymmetry breaking.
