Lenses appear in all sorts of everyday objects, from prescription eyeglasses to cell-phone cameras. Typically, lenses rely on a curved shape to bend and focus light. But in the tight spaces inside consumer electronics and ...
(PhysOrg.com) -- As researchers strive to increase the density and functionality of circuit elements onto computer chips, one newer option they have is a memory resistor (or “memristor”), the fourth passive circuit element. ...

LCDs (liquid crystal displays) provide a popular method for lighting screens on everything from computers and TVs to watches, clocks, cell phones and more. However, as scientists Sang Hoon Kim, Joo-Do Park and Ki-Dong Lee ...
(PhysOrg.com) -- In an effort to increase the recording densities of hard disk drives, patterned media has become one of the most promising strategies for achieving recording densities beyond 1 Tbit/in2. In patterned media, ...
Researchers have developed the first materials that can permanently change from solid to liquid, or vice versa, when exposed to light at room temperature, and remain in the new phase even after the light is removed. The researchers ...
(Phys.org)—Nanowires fashioned from DNA (deoxyribonucleic acid)—one of several type of molecular nanowires incorporating repeating molecular units—are exactly that: Geometrically wire-like DNA-based nanostructures defined ...
(Phys.org)—Scientists have developed a method for imprinting tiny yet complex 3-D structures on the tip of an optical fiber, whose 125-µm diameter is roughly the thickness of a human hair. The 3-D optical structures can ...
Semiconductor industry tools and instruments that work on the nanoscale could form a $5.5 billion market by 2012, experts told UPI's Nano World.
One secret to creating the world's fastest silicon-based flexible transistors: a very, very tiny knife.
Scientists could soon easily fabricate electronics and other structures only nanometers or billionths of a meter in size by stamping them out, following a new strategy that could help guarantee results, experts tell UPI's ...
