Velcro consists of one surface with loops, and another with hooks that latch onto the loops, joining opposing surfaces strongly. A miniaturised version of Velcro could be used in micro- and nanotechnology, but to form the surfaces, microwires are needed with properties that provide strength and durability.
Using the geometric and material properties of a unique nanostructure, Boston College researchers have uncovered a novel photonic effect where surface plasmons interact with light to form "plasmonic halos" of selectable output color.
A material that could enable faster memory chips and more efficient batteries can switch between high and low ionic conductivity states much faster than previously thought, SLAC and Stanford researchers have determined. The key is to use extremely small chunks of it.
The simple technique coats a cell with a silica solution to form a near-perfect replica of its structure. The process may simplify a wide variety of commercial fabrication processes from the nano- to macroscale.
The design of micro-electromechanical systems (MEMS) is about to undergo a technological revolution: experts from research institutions and industry are investigating entirely new methods for developing MEMS.
