Polymers that crawl like worms: How materials can develop direction without being told where to go
Researchers at the University of Vienna have uncovered a surprising phenomenon: polymer chains with segments that simply ...
reported in the journal Physical Review Letters. Led by graduate student Keng-hui Lin, scientists in the laboratory of Penn physicist Arjun G. Yodh measured the entropic forces exerted by rod-like ...
Researchers at the University of Vienna have uncovered a surprising phenomenon: polymer chains with segments that simply fluctuate at different ...
Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery quantum fields that govern particles, and gravity has stubbornly resisted ...
Statistical mechanics provides the framework for deriving macroscopic thermodynamic properties from the microscopic characteristics of matter. Central to this discipline is the concept of entropy, ...
Densely packed polymer chains can spontaneously start moving in one direction, even without being pushed, a finding that could explain DNA behavior and inspire new smart materials.
