Researchers at the US Department of Energy's Argonne National Laboratory have discovered a new way to generate 2D superconductivity at an interface of an insulating oxide material, at a higher transition temperature than ever seen before for these materials.

After developing a link discovery method in 2020 using terahertz radiation, Brown and Princeton researchers addressed what would happen if a wall or other reflector creates a non-line-of-sight path from the base station to the receiver. In APL Photonics, they consider two different generic types of transmitters and explore how their characteristics can be used to determine whether an NLOS path contributes to the signal received by the receiver.

How do different parts of the brain communicate with each other during learning and memory formation? A study by researchers at UC San Diego takes a first step at answering this fundamental neuroscience question, thanks to a neural implant that monitors multiple brain regions at the same time.

Wearable electronics have increasingly become a part of everyday life, so researchers wondered if these could be powered by harvesting electricity from waste heat. Further inspiration came from a desire to ultimately fabricate energy converting devices from the same materials as the active devices themselves. In Applied Physics Letters, the researchers report the design and fabrication of single-wall carbon nanotube thermoelectric devices on flexible polyimide substrates as a basis for wearable energy converters.

A new study from BYU published in Sleep Health challenges the premise made by phone manufacturers and found that the Night Shift functionality does not actually improve sleep.

A NUST MISIS professor was part of an international research team that has found evidence for the existence of the Zeeman spin-orbit coupling in antiferromagnetic conductors. This work may pave the way for the next generation of electronics. The study was published in npj Quantum Materials.

Osaka University researchers conducted a detailed multiphoton excitation photoluminescence (MPPL) analysis of gallium nitride (GaN) semiconductor substrates. The threading dislocations of GaN crystals observed using the nondestructive analysis technique were statistically classified to give the Burgers vectors. It is hoped that their findings will support the identification of fatal defects in GaN crystals to improve quality and yields and accelerate the availability of GaN-based devices.

Engineers at Duke University have developed the world's first fully recyclable printed electronics. By demonstrating a crucial and relatively complex computer component -- the transistor --created with three carbon-based inks, the researchers hope to inspire a new generation of recyclable electronics to help fight the growing global epidemic of electronic waste.

Researchers have developed the first LiDAR-based augmented reality head-up display for use in vehicles. Tests on a prototype version of the technology suggest that it could improve road safety by 'seeing through' objects to alert of potential hazards without distracting the driver.
