By relentlessly miniaturizing a pre-World War II computer technology, and combining this with a new and durable material, researchers at Case Western Reserve University have built nanoscale switches and logic gates that operate ...
A microelectromechanical system developed in Singapore provides the 360-degree view that is critical in diagnostic imaging.
(Phys.org) —Contrary to many textbook illustrations, electrons aren't just balls floating around an atom. In quantum theory, they're more like little tops, exhibiting "spin," and each creating its own tiny magnetic field.
(Phys.org) —Listen up nickel-titanium and all you other shape-memory alloys, there's a new kid on the block that just claimed the championship for elasticity and is primed to take over the shape memory apps market at the ...
(Phys.org) —Under the right circumstances, pushing on nothing is harder than pushing on something – at least when that "something" is gold. That's the finding from a new materials science paper, and it's a finding that ...
A research group comprised of Dr. Takayoshi Sasaki, NIMS Fellow, Dr. Tatsuo Shibata, post doctorate researcher, and other collaborators at the International Center for Materials Nanoarchitectonics of the National Institute ...
In HG Wells' 'The War of the Worlds', the invading Martians were beaten by that most unassuming of combatants – the common cold. Could the reverse happen and alien viruses pose a threat to human astronauts when they land ...
Long coils of optical waveguides any structure that can guide light, like conventional optical fiber can be used to create a time delay in the transmission of light. Such photonic delays are useful in military application ...
The submillimeter wave, or terahertz, part of the electromagnetic spectrum falls between the frequencies of 0.3 and 3 terahertz, between microwaves and infrared light. Historically, device physics has prevented traditional ...
Ultrasonography based on traditional bulk piezoelectric transducers has been established as an inexpensive and safe medical imaging modality. By borrowing techniques from the microelectronics industry, the performance of ...
