Research laboratories are constantly developing new materials that are expected to exhibit novel properties bound to revolutionize this or that technology. But it’s not enough to simply create these materials; scientists also need to find efficient methods of processing and fine-tuning them.

Moreover, composites are often made via the addition of nanoparticles into a base matrix, which is why it is necessary to find a way of manipulating the location, size, and concentration rate of these particles that would exclude even the smallest deviations that are invisible to the human eye.

Researchers from ITMO University have improved on the technique of local processing of composites based on nanoporous glass with addition of silver and copper. Now, it is possible to predict with high accuracy the optical properties of a plasmonic component during its treatment.

(Nanowerk News) Quantum technology holds great promise: Just a few years from now, quantum computers are expected to revolutionize database searches, AI systems, and computational simulations. Today already, quantum cryptography can guarantee absolutely secure data transfer, albeit with limitations. The greatest possible compatibility with our current silicon-based electronics will be a key advantage. And that is precisely where physicists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and TU Dresden have made remarkable progress: The team has designed a silicon-based light source to generate single photons that propagate well in glass fibers.

Archaeologists in Egypt said Saturday they had found 59 well-preserved and sealed wooden coffins over recent weeks that were buried more than 2,500 years ago.

Opening one of the ornately decorated sarcophagi before assembled media, the team revealed mummified remains wrapped in burial cloth that bore hieroglyphic inscriptions in bright colours.

The dramatic find was unearthed south of Cairo in the sprawling burial ground of Saqqara, the necropolis of the ancient Egyptian capital of Memphis, a UNESCO World Heritage site.

Researchers at the National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as drug delivery systems or flexible electrodes that can be inserted into the human body.

A standard 3D printer makes solid structures by creating sheets of material — typically plastic or rubber — and building them up layer by layer, like a lasagna, until the entire object is created.

Using a 3D printer to fabricate an object made of gel is a “bit more of a delicate cooking process,” said NIST researcher Andrei Kolmakov. In the standard method, the 3D printer chamber is filled with a soup of long-chain polymers — long groups of molecules bonded together — dissolved in water. Then “spices” are added — special molecules that are sensitive to light. When light from the 3D printer activates those special molecules, they stitch together the chains of polymers so that they form a fluffy weblike structure. This scaffolding, still surrounded by liquid water, is the gel.

The bad news is that this space rock is between 38 and 86 metres across, according to NASA — that’s about the size of three double-decker buses.

The good news is that it should swing past our home planet (Earth) with no chance of a direct hit.

It will be travelling at a mind-blowing 10.88 kilometers per second which is around 40,000 kilometres per hour.

Microsoft’s Teams had a very busy September adding a host of new features. Now, the firm is looking to improve the performance of its Teams service as it continues in the battle to beat Zoom in the video conferencing space.

In an update detailing the features added in September, Microsoft explained how it was trying to improve Teams’ performance as a large proportion of the workforce continue to work from home.

Microsoft says it’s working to ensure businesses and schools “have a high-performance experience that scales across their devices and levels of internet connectivity.”

Elon Musk confirmed that a new “vector-space bird’s eye view” is coming to Tesla vehicles under the FSD package.

Bird’s eye view, a vision monitoring system that renders a view of a vehicle from the top to help park and navigate tight spaces, has become a popular feature in premium vehicles and it has even moved down market over the last few years.

It is generally made possible due to an array of 5 or 6 camera around the vehicle.
