American Institute of Physics Tiny self-assembling tools could one day deliver drugs to targeted areas of the body or even perform autonomous microsurgery Researchers from the University of Twente in the Netherlands have taken the precise art of origami down to the microscopic scale. Using only a drop of water, the scientists have folded flat sheets of silicon nitride into cubes, pyramids, half soccer-ball-shaped bowls and long triangular structures that resemble Toblerone chocolate...

Mapping Origins And Uses Of Wrinkles, Creases And Folds
2013-07-18 08:48:26

Brown University Engineers from Brown University have mapped out the amounts of compression required to cause wrinkles, creases, and folds to form in rubbery materials. The findings could help engineers control the formation of these structures, which can be useful in designing nanostructured materials for flexible electronic devices or surfaces that require variable adhesion. "When a rubbery material is compressed and reaches a critical load, it experiences instability and forms...

Wrinkles and folds are ubiquitous. They occur in furrowed brows, planetary topology, the surface of the human brain, even the bottom of a gecko's foot. In many cases, they are nature's ingenious way of packing more surface area into a limited space. Scientists, mimicking nature, have long sought to manipulate surfaces to create wrinkles and folds to make smaller, more flexible electronic devices, fluid-carrying nanochannels or even printable cell phones and computers. But to attain those...

Using Light, Researchers Convert 2-D Patterns Into 3-D Objects

[ Watch the Video ] Researchers from North Carolina State University have developed a simple way to convert two-dimensional patterns into three-dimensional (3-D) objects using only light. “This is a novel application of existing materials, and has potential for rapid, high-volume manufacturing processes or packaging applications,” says Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State and co-author of a paper describing the...

Big Cat Roars Similar To Babies Crying
2011-11-03 05:10:16

When lions and tigers roar loudly and deeply — terrifying every creature within earshot — they are somewhat like human babies crying for attention, although their voices are much deeper. So says the senior author of a new study that shows lions' and tigers' loud, low-frequency roars are predetermined by physical properties of their vocal fold tissue — namely, the ability to stretch and shear — and not by nerve impulses from the brain. "Roaring is similar to what...

A coupled line of swinging pendulums apparently has nothing in common with an elastic film that buckles and folds under compression while floating on a liquid, but scientists at the University of Chicago and Tel Aviv University have discovered a deep connection between the two phenomena. Energy carried in ordinary waves, like those seen on the ocean near a beach, quickly disperses. But the energy in the coupled pendulums and in compressed elastic film concentrates into different kinds of...
