The bulk properties of polymer solutions are sensitive to polymer concentration. Polymer solutions are typically described as being either dilute, semi-dilute, or concentrated. The concentration ...

The universe can be a very sticky place, but just how sticky is a matter of debate. That is because for decades cosmologists have had trouble reconciling the classic notion of viscosity based on the ...

Mathematicians and physicists have come up with a new approach to calculate cosmic viscosity and the formulation favors the 'Big Rip' scenario for the end of the universe. The universe can be a very ...

That is because for decades cosmologists have had trouble reconciling the classic notion of viscosity based on the laws of thermodynamics with Einstein's general theory of relativity. However, a team ...
