When you deform a soft material such as Silly Putty, its properties change depending on how fast you stretch and squeeze it. If you leave the putty in a small glass, it will eventually spread out like a liquid. If you pull ...
Polymers are very large molecules consisting of thousands, even millions, of atoms bonded together in a repeating pattern similar to a chain. They make up many of the things around us we consider part of our everyday lives, ...
Researchers from the University of Illinois at Urbana-Champaign have developed a new technique for extremely high speed photonic sensing of the mechanical properties of freely flowing particles using an opto-mechano-fluidic ...
A University of Maryland-led team of researchers has developed an optical microscopy technique capable of shedding new light on how the mechanical properties of cells change in the course of aging, injury healing and disease ...
Getting ketchup out of the bottle isn’t always easy. However, shaking the bottle before trying to pour allows the thick, gooey ketchup to flow more freely because it becomes more fluid when agitated. The opposite is not ...
Blood coursing through vessels, lubricated cartilage sliding against joints, ink jets splashing on paper—living and nonliving things abound with fluids meeting solids. However important these liquid/solid boundaries may ...
A novel three-dimensional (3-D) touchless interactive display can change color based on the distance of the user's finger from the screen by detecting subtle shifts in ambient relative humidity, according to a new study. ...
In previous papers, University of Pennsylvania physicists investigated the "coffee ring effect," the ring-shaped stain of particles left after drops of coffee evaporate. In one paper, they learned how to undo this effect ...
A team of three University of Delaware mechanical engineering professors, plus researchers from three other academic institutions, are collaborating to develop three-dimensional (3D) carbon nanotube structures.
Semicrystalline polymers are solids that are assumed to flow only above their melting temperature. In a new study published in Science Advances, Chien-Hua Tu and a research team at the Max Planck Institute for Polymer Research ...
