Defect engineering accelerates carrier relaxation in GaN-based LEDs

A study conducted by researchers from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences has demonstrated how nitrogen vacancies (VN) resolve asymmetric carrier injection in GaN-based light-emitting diodes (LEDs), providing a practical way to improve device efficiency.

Photonic origami folds glass into microscopic 3D optical devices

Researchers have developed a technique to fold glass sheets into microscopic 3D photonic structures directly on a chip—a process they call photonic origami. The method could enable tiny, yet complex optical devices for data processing, sensing and experimental physics.

Expert says Humans are Aliens—and we were brought to Earth hundreds of thousands of years ago

What if Humans are the aliens we’ve been looking for all along? According to experts, humans were most likely crossbred with another species, perhaps from the star system Alpha Centauri –which is one of the closest solar systems to Earth—in the distant past, giving birth to modern humans.

Analysis suggests the most likely places to detect signals from an extraterrestrial intelligence

If an extraterrestrial intelligence were looking for signs of human communications, when and where should they look? In a new study, researchers at Penn State and NASA’s Jet Propulsion Laboratory in Southern California analyzed when and where human deep space transmissions would be most detectable by an observer outside our solar system and suggest that […]

‘Rosetta stone’ of code allows scientists to run core quantum computing operations

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate.

Astronomers combine X-ray and radio data to map pulsar ‘hand’ nebula

In 2009, NASA’s Chandra X-ray Observatory released a captivating image: a pulsar and its surrounding nebula that is shaped like a hand. Since then, astronomers have used Chandra and other telescopes to continue to observe this object. Now, new radio data from the Australia Telescope Compact Array (ATCA) has been combined with Chandra’s X-ray data […]

Cost-effective method developed for high-entropy alloy film production

A collaborative research team has developed a novel method for forming high-performance high-entropy alloy (HEA) films on various surfaces without using expensive alloy targets. This was achieved using a proprietary rotating target composed of multiple pure metal segments and pulsed laser deposition (PLD) technology.

It features precision cuts and extremely well-polished surfaces which many authors believe are traces left behind by an advanced ancient […]

Ceres may have had long-standing energy to fuel habitability

New NASA research has found that Ceres may have had a lasting source of chemical energy: the right types of molecules needed to fuel some microbial metabolisms. Although there is no evidence that microorganisms ever existed on Ceres, the finding supports theories that this intriguing dwarf planet, which is the largest body in the main […]
