The ultimate molecular chess match
For the last two decades, it's been said that carbon nanotubes hold the promise to transform a range of fields, from alternative energy to drug delivery. But making that happen has proved difficult, according to Hicham Fenniri, ...
Researchers build 3-D structures out of liquid metal
(Phys.org) —Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature.
Carbon 'candy floss' could help prevent energy blackouts
(Phys.org) —Ultra-light, high performance electrical wiring, made from carbon instead of copper, has been developed in a usable form for the first time.
The observation of truly metallic behavior in an organic material heralds a new generation of electronic devices
When we think about metals, objects like copper wires and sheets of iron spring to mind. However, organic materials—those based, as all living matter, on carbon and oxygen atoms—can also exhibit metallic ...
Researchers create self-healing, stretchable wires using liquid metal
(Phys.org)—Researchers from North Carolina State University have developed elastic, self-healing wires in which both the liquid-metal core and the polymer sheath reconnect at the molecular level after being ...
Novel optical-fiber design could reduce inefficiency and enable faster transmission of data-carrying light pulses
Optical fibers are rapidly replacing electrical wires as the primary medium for sending digital information over long distances. Without suffering from interference, pulses of light travelling along these ...
New nanotube fibers have unmatched combination of strength, conductivity, flexibility (w/ video)
(Phys.org)—Rice University's latest nanotechnology breakthrough was more than 10 years in the making, but it still came with a shock. Scientists from Rice, the Dutch firm Teijin Aramid, the U.S. Air Force ...
Researchers use liquid metal to create wires that stretch eight times their original length
(Phys.org)—Researchers from North Carolina State University have created conductive wires that can be stretched up to eight times their original length while still functioning. The wires can be used for ...
Multimode waveguides bring light around corners
(Phys.org)—Light has become one of our most powerful servants, carrying information ranging from a chat room "LOL" to an entire digitized movie through hundreds of miles of fiber optics in seconds. But ...
New study reveals challenge facing designers of future computer chips
To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.
Researchers demonstrate how graphene-metal interfaces influence electrons
(Phys.org)—Graphene, an atom-thin layer of pure carbon, appears to have many of the properties needed to usher in the next generation of electronic devices. The next step in building those devices, however, ...
Nanocables light way to the future: Researchers power line-voltage light bulb with nanotube wire
(PhysOrg.com) -- Cables made of carbon nanotubes are inching toward electrical conductivities seen in metal wires, and that may light up interest among a range of industries, according to Rice University researchers.
Tiny wires change behavior at nanoscale
Thin gold wires often used in high-end electronic applications are wonderfully flexible as well as conductive. But those qualities don't necessarily apply to the same wires at the nanoscale.
Small wires make big connections for microelectronics
University of Illinois engineers have developed a novel direct-writing method for manufacturing metal interconnects that could shrink integrated circuits and expand microelectronics.
