Closing in on ‘holy grail’ of room temperature quantum computing chips

Posted by in categories: computing, engineering, nanotechnology, quantum physics

To process information, photons must interact. However, these tiny packets of light want nothing to do with each other, each passing by without altering the other. Now, researchers at Stevens Institute of Technology have coaxed photons into interacting with one another with unprecedented efficiency — a key advance toward realizing long-awaited quantum optics technologies for computing, communication and remote sensing.

The team, led by Yuping Huang, an associate professor of physics and director of the Center for Quantum Science and Engineering, brings us closer to that goal with a nano-scale chip that facilitates photon interactions with much higher efficiency than any previous system. The new method, reported as a memorandum in the Sept. 18 issue of Optica, works at very low energy levels, suggesting that it could be optimized to work at the level of individual photons — the holy grail for room-temperature quantum computing and secure quantum communication.

“We’re pushing the boundaries of physics and optical engineering in order to bring quantum and all-optical signal processing closer to reality,” said Huang.

Coating That Could Destroy COVID-19 Virus, for Use in Hospital Masks, in Development

Posted by in categories: biotech/medical, health, nanotechnology

Researchers at the University of Central Florida (UCF) are working to create a protective coating that would include a new nanomaterial to catch #COVID19 and kill it within seconds.


ORLANDO, Fla., April 10, 2020 — The masks that health care workers wear to protect them from the virus that causes COVID-19 block the virus before it reaches their faces, but do not destroy it. To further protect doctors, nurses, and others on the front lines of the pandemic, researchers at the University of Central Florida (UCF) are working to create a protective coating that would include a new nanomaterial to catch the virus and kill it within seconds.

Scientists capture 3D images of nanoparticles, atom

Posted by in categories: nanotechnology, particle physics

O,.,o.


Since their invention in the 1930s, electron microscopes have helped scientists peer into the atomic structure of ordinary materials like steel, and even exotic graphene. But despite these advances, such imaging techniques cannot precisely map out the 3D atomic structure of materials in a liquid solution, such as a catalyst in a hydrogen fuel cell, or the electrolytes in your car’s battery.

Now, researchers at Berkeley Lab, in collaboration with the Institute for Basic Science in South Korea, Monash University in Australia, and UC Berkeley, have developed a technique that produces atomic-scale 3D images of nanoparticles tumbling in liquid between sheets of graphene, the thinnest material possible.

The future is nano, and it will revolutionise medical science Essays

Posted by in categories: bioengineering, biotech/medical, computing, nanotechnology, science

If you’ve been interested in nanotech, but have been too afraid to ask, here is an introductory and interesting article that I’d like to recommend.

My interest in nanotech is based on my hope that nanotech can lead to methods of constructing substrates that are suitable for mind uploading. It may lead to a technique to create duplicate minds.

“These ‘biological engineering’ technologies have made real one of the dreams of the nanotechnology pioneers: the deployment of molecular assemblers able to construct any shape with atomic precision, following a rational design.”

Engineer uses metal-oxide nanomaterials deposited on cloth to wipe out microbes

Posted by in categories: biological, chemistry, engineering, health, nanotechnology, sustainability

In an effort to make highly sensitive sensors to measure sugar and other vital signs of human health, Iowa State University’s Sonal Padalkar figured out how to deposit nanomaterials on cloth and paper.

Feedback from a peer-reviewed paper published by ACS Sustainable Chemistry and Engineering describing her new fabrication technology mentioned the metal-oxide nanomaterials the assistant professor of mechanical engineering was working with—including , cerium oxide and copper oxide, all at scales down to billionths of a meter—also have .

“I might as well see if I can do something else with this technology,” Padalkar said. “And that’s how I started studying antimicrobial uses.”

Cell muscle movements visualised for first time

Posted by in categories: materials, nanotechnology

The movements of cell muscles in the form of tiny filaments of proteins have been visualised at unprecedented detail by University of Warwick scientists.

In a study published in the Biophysical Journal, scientists from the University’s Department of Physics and Warwick Medical School have used a new microscopy technique to analyse the molecular motors inside that allow them to move and reshape themselves, potentially providing new insights that could inform the development of new smart materials.

Myosin is a protein that forms the motor filaments that give a cell stability and are involved in remodelling the actin cortex inside the cell. The actin cortex is much like the backbone of the cell and gives it its shape, while the myosin filaments are similar to muscles. By ‘flexing’, they enable the cell to exert forces outside of it and to propagate.

Researchers use nanotechnology to develop new treatment for endometriosis

Posted by in category: nanotechnology

Scientists have developed a precise, nanotechnology-based treatment to alleviate the pain and fertility problems associated with endometriosis, a common gynecological condition in women of childbearing age.

Research led by Oleh Taratula of the Oregon State University College of Pharmacy and Ov Slayden of the Oregon National Primate Research Center at Oregon Health & Science University used photo-responsive nanoparticles loaded with dye to find and remove the lesions associated with the disorder.

Findings were published today in the journal Small.

A single nanoparticle is just 300 nanometers wide, but an array of them create what’s called a metamaterial with superior capabilities. Researchers used this tech to create better night vision goggles powered by nanocrystals, which can convert photons of infrared light into visible light.
