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...
[ 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 research....
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 baby sounds...
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...
Discovery by George Washington University researchers may improve treatmentsFrom a baby's first blurted "bowl!'" for the word "ball" to the whispered goodbye of a beloved elder, the capacity for complex vocalizations is one of humankind's most remarkable attributes -- and perhaps one we take for granted most of our lives.Not so for people who are afflicted with paralysis to their vocal folds and who suffer the social stigma of affected speech. Nor so for engineering...
Physicists find clues to the origin and evolution of wrinkles in thin sheetsAs a sign of aging or in a suit, wrinkles are almost never welcome, but two papers in the current issue of Physical Review Letters offer some perspective on what determines their size and shape in soft materials.Jiangshui Huang and colleagues at the University of Massachusetts, Amherst explore how wrinkles in a sheet adapt to an edge that prefers to be flat. They float a thin, rectangular film of common plastic...
VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 6, 2008) - ATAC Resources Ltd. (TSX VENTURE:ATC) is pleased to announce very significant gold results from diamond drilling at its wholly owned Rau property in the Keno Hill District of central Yukon. The discovery lies on the northern edge of the prolific Tintina Gold Province, a belt of mostly intrusion-related gold deposits that stretches across Yukon and Alaska. Encouraging surface results and visual evaluation of drill core have now been...
