Long-distance transport of electron spins for spin-based logic devices

Posted by in categories: computing, quantum physics

Almost all electronic devices operate by using an electron charge controlled by electrical means. In addition to a charge, an electron has a spin as a magnetic property. A groundbreaking concept for information processing based on electron spins is proposed using electron spins in semiconductors. Quantum computing enables us to exceed the speed of conventional computing and a spin transistor reduces energy consumption.

However, electron spins have yet to be used in realistic electronic devices except as part of magnetic devices for information storage. The reason is that spin polarization in a semiconductor is easily randomized, and consequently, it is difficult to transport spin polarization over a long distance.

An electron spin itself is a quantum spin angular momentum. Electrical transport and the manipulation of spin polarization are essential technologies if electron spins are to be employed in a device.

‘Honeycomb’ of nanotubes could boost genetic engineering

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology

Nice


Researchers have developed a new and highly efficient method for gene transfer. The technique, which involves culturing and transfecting cells with genetic material on an array of carbon nanotubes, appears to overcome the limitations of other gene editing technologies.

The device, which is described in a study published today in the journal Small, is the product of a collaboration between researchers at the University of Rochester Medical Center (URMC) and the Rochester Institute of Technology (RIT).

Crumpling approach enhances photodetectors’ light responsivity

Posted by in categories: biotech/medical, computing, engineering, particle physics, wearables

HUGE deal for wearables and biomed technologies.


Researchers from the University of Illinois at Urbana-Champaign have demonstrated a new approach to modifying the light absorption and stretchability of atomically thin two-dimensional (2D) materials by surface topographic engineering using only mechanical strain. The highly flexible system has future potential for wearable technology and integrated biomedical optical sensing technology when combined with flexible light-emitting diodes.

“Increasing graphene’s low light absorption in visible range is an important prerequisite for its broad potential applications in photonics and sensing,” explained SungWoo Nam, an assistant professor of mechanical science and engineering at Illinois. “This is the very first stretchable photodetector based exclusively on graphene with strain-tunable photoresponsivity and wavelength selectivity.”

Mining Dams Grow to Colossal Heights, and So Do the Risks

Posted by in category: space

We have China in 2017 wanting to mine the dark side of the moon hoping to find Gold. We have others wanting to mine Mars. With the mining lessons over the centuries and the damage it has created over time; is anyone else concern how mining the moon could impact our planet and space itself?


Engineers say Brazilian disaster shows world-wide danger from Hoover Dam-size earthen structures holding ‘tailings’ waste

Paul Kiernan.

MARIANA, Brazil—Half an hour’s drive from this colonial town in southeast Brazil, trees suddenly give way to what looks like a desert salt flat. It is a 2-mile-wide valley filled with mine waste.

Samsung Files Patent For Augmented Reality Smart Contact Lenses

Posted by in categories: augmented reality, electronics, mobile phones, transportation

Samsung’s dream of creating smart contact lenses capable of capturing images and shooting videos has just drawn closer. However, the patent reveals that Samsung has been working on the concepts and not necessarily the actual product which they trademarked as Gear Blink, which was filed in both South Korea and the U.S.

‘The analysis component of the contact lens can process the raw image data of the camera to determine processed image data indicating that the blind person is approaching intersection with a crosswalk and establish that there is a vehicle approaching the intersection’. It could very well be a smart contact lens. It’s a contact lens that consists of a small display, camera, RF antenna, and sensors to detect eye movement.

SamMobile states that the “lenses can provide a more natural way to provide augmented reality than smart glasses”. While the display projects images directly into the eye of the person wearing the contacts, an external device like a smartphone is needed for processing.
