Can radar replace stethoscopes?

Tue, 2018-08-14 19:45
Electronic engineers have developed a procedure for reliably detecting and diagnosing heart sounds using radar. In future, mobile radar devices could replace conventional stethoscopes and permanent touch-free monitoring of patients' vital functions could be possible using stationary radar devices.

Long-sought carbon structure joins graphene, fullerene family

Tue, 2018-08-14 04:31
Scientists have been playing with pure carbon compounds for centuries, starting with diamond and graphite and now with fullerenes, nanotubes and graphene. One type of 3D geometry has been missing, however: a negatively curved carbon-cage surface called schwarzite. Chemists have now shown that serendipitously produced materials called zeolite-templated carbons are in fact the long-sought schwarzites. Their recipe for making schwarzites could make them practical in electronics and gas storage.

Researchers have incorporated electronic devices into soft fabrics, potentially making it possible to produce clothing that communicates optically with other devices.

Tying down electrons with nanoribbons

Wed, 2018-08-08 23:12
Nanoribbons are promising topological materials displaying novel electronic properties. Chemists and physicists have found a way to join two different types of nanoribbon to create a topological insulator that confines single electrons to the junction between them. Alternating nanoribbon types create a chain of interacting electrons that act as metals, insulators or interacting spins -- qubits for a quantum computer -- depending on separation. This opens the door to designer materials with unique quantum properties.

Thu, 2018-08-02 01:26
Researchers have developed a new technique to control self-folding three-dimensional (3D) structures. Specifically, the researchers use templates to constrain deformation in certain selected areas on a two-dimensional structure, which in turn dictates the resulting 3D structure of the material.

3D printing the next generation of batteries

Tue, 2018-07-31 01:33
3D printing can be used to manufacture porous electrodes for lithium-ion batteries -- but because of the nature of the manufacturing process, the design of these 3D printed electrodes is limited to just a few possible architectures. Until now, the internal geometry that produced the best porous electrodes through additive manufacturing was what's known as an interdigitated geometry -- metal prongs interlocked like the fingers of two clasped hands, with the lithium shuttling between the two sides.

Blasting tiny craters in glass, creating material to miniaturize telecommunication devices

Tue, 2018-07-24 21:13
Modern communication systems often employ optical fibers to carry signals across or between devices, combining more than one function into a single circuit. However, signal transmission requires long optical fibers, which makes miniaturizing the device difficult. Instead of long optical fibers, scientists have started testing planar waveguides. Investigators now report on a laser-assisted study of a type of glass that shows promise as a material for broadband planar waveguide amplifiers.
