Air-filled Fiber Cables capable of Outperforming standard Optical fibers

Air-filled fiber cables capable of outperforming standard optical fibers
“Hollow core optical fibres with comparable attenuation to silica fibres between 600 and 1100 nm” has been published in Nature Communications with DOI 10.1038/s41467-020-199107

The next generation of optical fiber could be a step closer as a new study has shown that fibers with a hollowed out center, created in Southampton, could reduce loss of power currently experienced in standard glass fibers.

The COVID-19 crisis has seen people all over the world rapidly move their work and social lives online and communities have never relied on the internet more. The ever-increasing number of Zoom calls and webinars has highlighted the need to keep advancing the technology that has made this possible.

For over 50 years, optical fibers made of silica glass have been the transmission med...

An Improved Technique for Wireless Power Transfer technology

Going beyond the anti-laser may enable long-range wireless power transfer. Charging a smartphone wirelessly nowadays is not a big deal. You have to put your smartphone on a charging pad. But usable long-range wireless power transfer, like from one room to another or even across the building, is still in progress.

Most of the development methods involve focusing narrow beams of energy and aiming them at their intended target. These methods have had some success but are, so far, not very efficient. And having focused electromagnetic beams flying around through the air is unsettling.

Scientists from the University of Maryland (UMD), in collaboration with a colleague at Wesleyan University in Connecticut, have developed an improved technique for wireless power transfer...

Sound Waves power New Advances in Drug Delivery and Smart Materials

The patented ‘Respite’ nebuliser uses high-frequency sound waves to precisely deliver drugs to the lungs.
The patented ‘Respite’ nebuliser uses high-frequency sound waves to precisely deliver drugs to the lungs.

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations.

While sound waves have been part of science and medicine for decades — ultrasound was first used for clinical imaging in 1942 and for driving chemical reactions in the 1980s — the technologies have always relied on low frequencies.

Now researchers at RMIT University in Melbourne, Australia, have shown how high frequency sound waves could revolutionise the field of ultrasound-driven chemistry.

A new review published in Advanced Science reveals the bizarre effects of these sound w...

World’s Smallest Atom-Memory Unit created

image003

Faster, smaller, smarter and more energy-efficient chips for everything from consumer electronics to big data to brain-inspired computing could soon be on the way after engineers at The University of Texas at Austin created the smallest memory device yet. And in the process, they figured out the physics dynamic that unlocks dense memory storage capabilities for these tiny devices.

The research published recently in Nature Nanotechnology builds on a discovery from two years ago, when the researchers created what was then the thinnest memory storage device. In this new work, the researchers reduced the size even further, shrinking the cross section area down to just a single square nanometer.

Getting a handle on the physics that pack dense memory storage capability into these devi...
