Hollow spheres made of metal
Producing metallic hollow spheres is complicated: It has not yet been possible to make the small sizes required for new high-tech applications. Now for the first time researchers have manufactured ground hollow ...
Copper Nanowires Enable Bendable Displays, Solar Cells
(PhysOrg.com) -- A team of Duke University chemists has perfected a simple way to make tiny copper nanowires in quantity. The cheap conductors are small enough to be transparent, making them ideal for thin-film ...
Study brings brain-like computing a step closer to reality
(PhysOrg.com) -- The development of 'brain-like' computers has taken a major step forward today with the publication of research led by the University of Exeter.
Nanoengineers can print 3D microstructures in mere seconds
(Phys.org)—Nanoengineers at the University of California, San Diego have developed a novel technology that can fabricate, in mere seconds, microscale three dimensional (3D) structures out of soft, biocompatible ...
Spider know-how could cut future energy costs
(PhysOrg.com) -- Scientists at Oxford University and The University of Sheffield have demonstrated that natural silks are a thousand times more efficient than common plastics when it comes to forming fibres.
Researchers strain to improve electrical material and it's worth it
Like turning coal to diamond, adding pressure to an electrical material enhances its properties. Now, University of Illinois at Urbana-Champaign researchers have devised a method of making ferroelectric thin ...
Worlds first commercial nanostructured bulk metal
When we think of structural materials, we usually imagine something big, strong and bulky, like steel beams in bridges and buildings, and while we are becoming familiar with composites reinforced with carbon ...
Duke engineers make strides toward artificial cartilage
A Duke research team has developed a better recipe for synthetic replacement cartilage in joints.
Seeking the ability to design, control and build new materials at the level of individual atoms
The ability to design, control and build new materials at the level of individual atoms could open up a whole new world of electronic devices.
Engineers find inspiration for new materials in Piranha-proof armor
(PhysOrg.com) -- Its a matchup worthy of a late-night cable movie: put a school of starving piranha and a 300-pound fish together, and who comes out the winner?
First light from the first high-energy superconducting undulator
(Phys.org)—More than eight years of effort by Advanced Photon Source (APS) physicists, engineers, and technicians culminated on Jan. 21, 2013, with the production of the first X-rays from the prototype ...
Sensor detects glucose in saliva and tears for diabetes testing
(Phys.org) -- Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine and might be manufactured at low cost because it does not require ...
Researchers find ordinary pen ink useful for building a supercapacitor
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 ...
