Quantum-level control of an exotic topological quantum magnet

Posted by in categories: nanotechnology, quantum physics, transportation

This would be good for hoverboards and aircrafts.


Physicists have discovered a novel quantum state of matter whose symmetry can be manipulated at will by an external magnetic field. The methods demonstrated in a series of experiments could be useful for exploring materials for next-generation nano- or quantum technologies.

Close.

What’s My Best Chance of Living Forever?

Posted by in categories: alien life, life extension

This makes for a microcosm of people on the outside looking in who do not follow on a regular basis. A basic headline of living forever followed by comments of doubt or silliness and the heat death of the universe. Of the experts, I like Sinclair’s answer best.


What do hideous mall t-shirts, emo bands from the mid-aughts, and gorgeously-wrought realist novels about dissolving marriages have in common? Simply this assertion: Life Sucks. And it does suck, undoubtedly, even for the happiest and/or richest among us, not one of whom is immune from heartbreak, hemorrhoids, or getting mercilessly ridiculed online.

Still, at certain points in life’s parade of humiliation and physical decay almost all of us feel a longing—sometimes fleeting, sometimes sustained—for it to never actually end. The live-forever impulse is, we know, driving all manner of frantic, crackpot-ish behavior in the fringier corners of the tech-world; but will the nerds really pull through for us on this one? What are our actual chances, at this moment in time, of living forever? For this week’s Giz Asks, we spoke with a number of experts to find out.

Single atoms as catalysts

Posted by in categories: particle physics, transportation

Incorporating individual metal atoms into a surface in the right way allows their chemical behavior to be adapted. This makes new, better catalysts possible.

They make our cars more environmentally friendly and they are indispensable for the : catalysts make certain chemical reactions possible—such as the conversion of CO into CO2 in car exhaust gases—that would otherwise happen very slowly or not at all. Surface physicists at the TU Wien have now achieved an important breakthrough; can be placed on a metal oxide surface so that they show exactly the desired . Promising results with iridium atoms have just been published in the renowned journal Angewandte Chemie.

Heat transport theory goes universal

Posted by in categories: energy, quantum physics

A new unified theory for heat transport accurately describes a wide range of materials – from crystals and polycrystalline solids to alloys and glasses – and allows them to be treated in the same way for the first time. The methodology, which is based on the Green-Kubo theory of linear response and concepts from lattice dynamics, naturally accounts for quantum mechanical effects and thus allows for the predictive modelling of heat transport in glasses at low temperature – a feat never achieved before, say the researchers who developed it. It will be important for better understanding and designing heat transporting devices in a host of applications, from heat management in high-power electronics, batteries and photovoltaics to thermoelectric energy harvesting and solid-state cooling. It might even help describe heat flow in planetary systems.

“Heat transport is the fundamental mechanism though which thermal equilibrium is reached,” explains Stefano Baroni of the Scuola Internazionale Superiore di Studi Avanzati (SISSA) in Trieste, Italy, who led this research effort. “It can also be thought of as the most fundamental manifestation of irreversibility in nature – as heat flows from warm areas in the same system to cooler ones as time flows from the past to the future (the ‘arrow of time’). What is more, many modern technologies rely on our ability to control heat transport.”

However, despite its importance, heat transport is still poorly understood and it is difficult to simulate the heat transport of materials because of this lack of understanding. To overcome this knowledge gap, researchers employ various simulation techniques based on diverse physical assumptions and approximations for different classes of material – crystals on one hand and disordered solids and liquids on the other.

NASA space probe shot an asteroid with lasers

Posted by in category: space

Pew face_with_colon_three


NASA’s OSIRIS-REx mission has been steadily progressing since the spacecraft arrived at the diamond-shaped space rock known as Bennu a few months back, but not everything has gone completely to plan.

The rock ended up being far more, well, dirty than NASA originally expected. Bennu’s surface is absolutely packed with debris, posing a challenge for NASA’s team that still has to decide where to have the probe touch down on the asteroid to collect samples. Now, using a laser instrument built into OSIRIS-REx, NASA has a detailed look at how dangerous the surface truly is.

Asteroid danger: ‘100% chance of impact’ space expert alerts in ‘life or death’ warning

Posted by in category: space

AN ASTEROID is “100 percent” certain to strike Earth even if we cannot predict when or where it will happen, according to a space expert who told Express.co.uk it is a “matter of life and death”.

World Record: 175 mins flight time and 100 KM range

Posted by in categories: business, drones, energy

Where to get the GAIA 160-Hybrid drone: https://www.foxtechfpv.com/gaia-160-hybrid-hexacopter-arf-combo.html

We did it!!!!!!
Broke the Flight Time Record!!!!!
This is a historic moment for UAV drone.
Foxtech GAIA 160-Hybrid has made aviation history by completing the 100km crossing sea bay flight in 180 minutes.
On 9th September, Foxtech team successfully completed the crossing sea bay flight with GAIA 160-Hybrid from changdao to dalian. GAIA 160-Hybrid took off from a yacht in changdao and landed on a coast of Dalian, the total range is 100km, this is the longest single flight of a hexacopter in the World! Foxtech GAIA 160-Hybrid hexacopter broke the flight time record!
FOXTECH GAIA 160-Hybrid hexacopter has an onboard 2000w generator that offers plenty of power to 6 very high efficiency motors to ensure a long flight time. It is installed with redundancy flight controllers, three GPS and a full range of optional equipments like RTK GPS, 20km datalink, parachute, secondary radio control to make this drone very reliable and very safe.
Foxtech team arrived in changdao on 5 September, but due to the heavy wind and bad weather conditions the flight was actually delayed, we have to stop the mission and wait for another good weather to try again. Finally, Foxtech team was ready to make their attempt on 9 September. Departing from a yacht in changdao, weather was cooperative and all was going well.
Foxtech GAIA 160-Hybrid successfully took off from the yacht, with GPS guidance and automated flight, the drone could fly independently. And the drone was accompanied by a yacht staying within a range of 500 meters, so that our operator could control the aircraft at any time. During the flight, the wind was rising, force 7 grades, the wind speed is about 17m/s. But with the robust stability of GAIA 160-Hybrid and rich experience of our technicist, GAIA 160-Hybrid overcame the adverse weather conditions, and just over 3 hours after takeoff, GAIA 160-Hybrid landed safely in a coast of Dalian.
The journey was filled with challenges, because any type of adverse wind will have a
severe impact on the drone. So this time the successful flight dramatically proved the.
reliability and potentials of GAIA 160-Hybrid, proved that Foxtech GAIA 160-Hybrid is a high-performance flying platform which is able to adapt many complicated environment, especially the strong breeze and gale weather. A longer flight time coupled with good stability of GAIA 160-Hybrid opens a wide range of new commercial possibilities for businesses such as inspection of offshore platforms, search and rescue, power line inspection etc.
