Core-shell nanoparticles with evolving forms

Core-shell iron-golf nanoparticles synthesized by UHV growth show an astonishing evolution of their morphology as the amount of gold increases, changing from a polyhedral shape to an iron cube coated by truncated gold pyramids. The origin of this evolution has been elucidated.

Biomimetic design of patterned insect carapaces

Replicating twisted liquid crystal patterns found in insects is extremely difficult. A solution based on an eco-design is published in Nature Communications. In addition, proof-of-concept prototypes of optical tags in cryptography are presented.

Florent Houdellier laureate of the CNRS crystal medal

Florent Houdellier is the 2020 laureate of the CNRS crystal medal which distinguishes research support personnel who, through their creativity, their technical mastery and their sense of innovation, contribute alongside researchers to the advancement of knowledge and to the excellence of French research!

Improved oxygen reduction reaction in fuel cell through carbon interphase

We propose a modified hybrid support consisting of unzipped carbon nanotubes and nitrogen and sulfur co-doped multi walled carbon nanotubes as high performance electrocatalyst for the oxygen reduction reaction in proton exchange membrane fuel cells.

Degradation of phase change memories

The Ge-Sb-Te layers used in phase change memories (PCM) degrade when left in contact with ambient air. Their crystallization temperature decreases and the selective oxidation upsets the stoichiometry...
