Solid-solid Phase Transitions via Melting in Metals
A solid-solid phase transition via an intermediate liquid state has been identified in colloidal systems, but the universality of the phenomenon at atomic scales has not yet been proved, mainly due to experimental constraints. In a recent Nature Communications manuscript, researchers at the Laboratory of Metal Physics and Technolog (LMPT) have now demonstrated via fast differential scanning calorimetry that a similar transition also occurs in metallic systems.

A Single Atom Magnet
Magnets possess both strength and memory. These two properties make them useful for a broad variety of applications, which involve action at a distance or retention of magnetic information. The miniaturization of magnets, like that of transistors, cannot go on indefinitely. As a magnet is reduced in size, thermal fluctuations overcome the anisotropy barrier that keeps the magnetic axis stable, leading to the loss of permanent magnetization.

Lindau Nobel Laureate Meetings Article: "New Wonder Materials – From Lab Specimens to Everyday Items"
It was sixteen years ago that physicist Nicola Spaldin discovered a brand new class of materials: multiferroics. To this day, little more is known about them, even in academic circles. Yet they feature a number of indisputable qualities.

Making Colloidal Molecules
The ISA group, in collaboration with IBM Research Zurich, has pioneered the fabrication of fully programmable colloidal molecules with complete and independent control on their shape and composition. These novel particles offer tremendous potential as building blocks for the assembly of complex materials and for microscopic studies on locomotion and the fabrication of micro-robots.
