Expanding the limits of Li-ion batteries: Electrodes for all-solid-state batteries

Mon, 2018-08-06 20:13
Scientists have addressed one of the major disadvantages of all-solid-state batteries by developing batteries with a low resistance at their electrode/solid electrolyte interface. The fabricated batteries showed excellent electrochemical properties that greatly surpass those of traditional and ubiquitous Li-ion batteries; thereby, demonstrating the promise of all-solid-state battery technology and its potential to revolutionize portable electronics.

Concepts for new switchable plasmonic nanodevices

Mon, 2018-08-06 19:22
Plasmonic waveguides open the possibility to develop dramatically miniaturized optical devices and provide a promising route towards the next-generation of integrated nanophotonic circuits for information processing, optical computing and others. Key elements of nanophotonic circuits are switchable plasmonic routers and plasmonic modulators.

New technique uses templates to guide self-folding 3D structures

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.

First-of-its-kind material for the quantum age

Wed, 2018-08-01 21:20
A physicist has discovered a new material that has the potential to become a building block in the new era of quantum materials, those that are composed of microscopically condensed matter and expected to change our development of technology.

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.

'Smart' machine components alert users to damage and wear

Tue, 2018-07-31 01:17
Scientists have used advanced additive manufacturing technology to create 'smart' machine components that alert users when they are damaged or worn.

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.
