CityHawk eVTOL Gets Off The Ground Following Initial Orders

Posted by in categories: biotech/medical, robotics/AI

“We are excited to partner with Hatzolah Air on the development of our CityHawk EMS vehicle,” says Rafi Yoeli, CEO of Urban Aeronautics. “Its compact size will enable it to land in the middle of a busy city street, making it a perfect fit for medical evacuation missions by dramatically decreasing the time it takes to arrive on-scene, treat and transport sick or injured patients to appropriate medical facilities.”

For those of you unfamiliar with the CityHawk, it’s much, much more than a few concept drawings. The vehicle has been in development since the company’s inception in 2001, and an unmanned version of the CityHawk has been flying successfully for at least a year. Successfully enough, at least, to merit an agreement of, “mutual exploration by Boeing and Tactical Robotics of Autonomous Unmanned VTOL aircraft based on Urban Aeronautics … unique Fancraft™ technology.”

Quantum Nanodevice Can Be Both a Heat Engine and Refrigerator at the Same Time

Posted by in categories: nanotechnology, particle physics, quantum physics

A multitasking nanomachine that can act as a heat engine and a refrigerator at the same time has been created by RIKEN engineers. The device is one of the first to test how quantum effects, which govern the behavior of particles on the smallest scale, might one day be exploited to enhance the performance of nanotechnologies.

Conventional heat engines and refrigerators work by connecting two pools of fluid. Compressing one pool causes its fluid to heat up, while rapidly expanding the other pool cools its fluid. If these operations are done in a periodic cycle, the pools will exchange energy and the system can be used as either a heat engine or a fridge.

It would be impossible to set up a macroscale machine that does both tasks simultaneously—nor would engineers want to, says Keiji Ono of the RIKEN Advanced Device Laboratory. “Combining a traditional heat engine with a refrigerator would make it a completely useless machine,” he says. “It wouldn’t know what to do.”

NASA to launch SphereX telescope into space in 2024

Posted by in category: space

During its two-year mission, SphereX will map the entire sky four times, creating an enormous database of stars, galaxies, nebulas and other celestial objects.

The space telescope will be NASA’s first to build a full-sky spectroscopy map in near-infrared, and it will observe a total of 102 near-infrared colours.

Physicists observe competition between magnetic orders

Posted by in categories: computing, encryption, nanotechnology, quantum physics, security

They are as thin as a hair, only a hundred thousand times thinner—so-called two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They became known to a wider audience when two Russian-British scientists were awarded the Nobel Prize in Physics in 2010 for the discovery of graphene, a building block of graphite. The special feature of such materials is that they possess novel properties that can only be explained with the help of the laws of quantum mechanics and that may be relevant for enhanced technologies. Researchers at the University of Bonn (Germany) have now used ultracold atoms to gain new insights into previously unknown quantum phenomena. They found out that the magnetic orders between two coupled thin films of atoms compete with each other. The study has been published in the journal Nature.

Quantum systems realize very unique states of matter originating from the world of nanostructures. They facilitate a wide variety of new technological applications, e.g. contributing to secure data encryption, introducing ever smaller and faster technical devices and even enabling the development of a quantum computer. In the future, such a computer could solve problems which conventional computers cannot solve at all or only over a long period of time.

How unusual quantum phenomena arise is still far from being fully understood. To shed light on this, a team of physicists led by Prof. Michael Köhl at the Matter and Light for Quantum Computing Cluster of Excellence at the University of Bonn are using so-called quantum simulators, which mimic the interaction of several quantum particles—something that cannot be done with conventional methods. Even state-of-the-art computer models cannot calculate complex processes such as magnetism and electricity down to the last detail.
