On-demand glass is right around the corner

A research group coordinated by physicists of the University of Trento was able to probe internal stress in colloidal glasses, a crucial step to controlling the mechanical properties of glasses. Their work opens the way to ...

Scientists discover new non-sticky gels

Scientists from the University of Bristol and Université Paris-Saclay have discovered a new class of material—non-sticky gels.

Charge change: How electric forces vary in colloids

When calculating electrokinetic force, the convention has been to assume that there is no relative velocity of the fluid compared to the surface, which holds true for hydrophilic surfaces. However, this needs to be reconsidered ...

Scientists discover 'electron equivalents' in colloidal systems

Atoms have a positively charged center surrounded by a cloud of negatively charged particles. This type of arrangement, it turns out, can also occur at a more macroscopic level, giving new insights into the nature of how ...

Shape-encoded dynamic assembly of mobile micromachines

Field-directed and self-propelled colloidal assembly can be used to build micromachines to perform complex motions and functions, although their integration as heterogenous components with specified structures, dynamics and ...
