Models for molecules show unexpected physics

Rice engineers show spinning magnetic particles surprisingly follow thermodynamic laws

17-Mar-2022

Small spheres suspended in a liquid move enough like molecules that the physics for one can be used to mimic the physics of the other. That’s why the discovery of some unusual physics incolloids-- particles dispersed in a solution such asmilk, for example-- could be of interest to ...

How order first appears in liquid crystals

24-May-2018

Liquid crystals undergo a peculiar type of phase change. At a certain temperature, their cigar-shaped molecules go from a disordered jumble to a more orderly arrangement in which they all point more or less in the same direction. LCD televisions take advantage of that phase change to project ...
