Engineers have been trying to devise increasingly efficient and low-cost methods to fabricate electronic components and devices on a large-scale. Recently, some studies explored the possibilities of creating electronics using solution processing techniques, which involve the deposition of materials with electrical properties from a solution onto a surface.

Researchers at Yonsei University and Sungkyunkwan University in South Korea recently fabricated wafer-scale transistor arrays based on the inorganic compound molybdenum-disulfide using a solution processing method. Their paper, published in Nature Electronics, could contribute to enabling the large-scale and low-cost fabrication of next-generation electronics.

“We have been working on solution-processed 2D nanomaterials for scalable electronic applications for years, yet satisfying both electronic performance and scalability based on solution-based approaches has been very challenging until now,” Joonhoon Kang and Jeong Ho Cho, co-authors of the paper, told Tech Xplore.

The use of single-photon.

A photon is a particle of light. It is the basic unit of light and other electromagnetic radiation, and is responsible for the electromagnetic force, one of the four fundamental forces of nature. Photons have no mass, but they do have energy and momentum. They travel at the speed of light in a vacuum, and can have different wavelengths, which correspond to different colors of light. Photons can also have different energies, which correspond to different frequencies of light.

Electron tunneling associated with ferritin was proposed as early as 1988, but it is still viewed skeptically despite substantial evidence that it occurs. In our recent paper published in IEEE Transactions on Molecular, Biological and Multi-Scale Communications, my co-authors and I review the evidence of electron tunneling in ferritin, as well as the evidence that such electron tunneling may be used by biological systems that include the retina, the cochlea, macrophages, glial cells, mitochondria and magnetosensory systems.

While these diverse systems fall in different fields of study, we hope that this article will raise awareness of the mechanism of electron tunneling associated with ferritin and encourage further research into that phenomenon in biological systems that incorporate ferritin, particularly where there is no apparent need for the iron storage functions of ferritin in those systems.

Ferritin is an iron storage protein that self-assembles into a 12-nanometer diameter spherical shell that is 2 nanometers thick, and it can store up to ~4,500 iron atoms in an 8-nanometer diameter core. With an evolutionary history that appears to stretch back more than 1.2 billion years, it might seem rather old, but it should be kept in mind that single-celled organisms are believed to have first evolved ~3.5 billion years ago. As such, it may have taken more than 2 billion years for ferritin to evolve. When the first multicellular organisms evolved ~600 million years ago, members of the ferritin family of proteins were likely present, and they can be found today in almost all plants and animals.

ChargePoint announced today that it is adopting Tesla’s NACS connector, which will be offered on new and existing charging stations.

Soon after Ford and then GM/Rivian announced that it was adopting NACS, Tesla’s proprietary connector that it decided to open to the rest of the industry, virtually all charging station manufacturers and operators announced that they will offer NACS connectors on their charging stations.

But there was a big one missing: ChargePoint.

However, researchers at the University of Cambridge have recently made a discovery that could revolutionize computer memory, addressing energy efficiency and performance.

The Tesla Cybertruck automatic tailgate and tonneau cover motions, as well as its interior have been extensively filmed during its chief designer visit to an EV exhibit inauguration at Peterson’s museum. The new shots also revealed a cool storage space under a lid in the truck bed as well as possibly vented seats.

Using the Spectrum–RG (SRG) spacecraft and two ground-based telescopes, Russian astronomers have observed X-ray sources in the eastern Galactic sky. The observational campaign resulted in the detection of 14 new active galactic nuclei. The findings were presented June 6 in the journal Astronomy Letters.

An active galactic nucleus (AGN) is a compact region at the center of a galaxy, more luminous than the surrounding galaxy light. AGNs are very energetic due either to the presence of a black hole or star formation activity at the core of the galaxy.

Astronomers generally divide AGNs into two groups based on emission line features. Type 1 AGNs show broad and narrow emission lines, while only narrow emission lines are present in Type 2 AGNs.

A prototype drone developed at Imperial College London is able to withstand temperatures of up to 200°C for 10 minutes.

The so-called FireDrone (Opens in a new window) is designed to fly into burning buildings or forest fires and provide “crucial first-hand data” otherwise unavailable to first responders. For example, identifying where people are trapped in a burning building without fire fighters needing to perform a room-by-room search.

The Europe Union is introducing “crash test” systems for artificial intelligence to ensure new innovations are safe before they hit the market.

The trade bloc launched four permanent testing and experimental facilities across Europe on Tuesday, having injected €220 million ($240 million) into the project. The centers, which are virtual and physical, will from next year give technology providers a space to test AI and robotics in real-life settings within manufacturing, health care, agriculture and food, and cities.
