Generating quantum correlations between light and microwaves.

Non-classical microwave–optical photon pair generation with a chip-scale transducer.


A transducer that generates microwave–optical photon pairs is demonstrated. This could provide an interface between optical communication networks and superconducting quantum devices that operate at microwave frequencies.

There’s one last place Planet Nine could be Hiding

Posted by in category: space

A study recently submitted to The Astronomical Journal continues to search for the elusive Planet Nine (also called Planet X), which is a hypothetical planet that potentially orbits in the outer reaches of the solar system and well beyond the orbit of the dwarf planet, Pluto.

The goal of this study, which is available on the pre-print server arXiv, was to narrow down the possible locations of Planet Nine and holds the potential to help researchers better understand the makeup of our solar system, along with its formation and evolutionary processes. So, what was the motivation behind this study regarding narrowing down the location of a potential Planet 9?

Dr. Mike Brown, who is a Richard and Barbara Rosenberg Professor of Astronomy at Caltech and lead author of the study, tells Universe Today, “We are continuing to try to systematically cover all of the regions of the sky where we predict Planet Nine to be. Using data from Pan-STARRS allowed us to cover the largest region to date.”

Chameleons inspire new Multicolor 3D-Printing Technology

Posted by in categories: 3D printing, chemistry, engineering, sustainability

Inspired by the color-changing ability of chameleons, researchers have developed a sustainable technique to 3D-print multiple, dynamic colors from a single ink.

“By designing new chemistries and printing processes, we can modulate structural color on the fly to produce color gradients not possible before,” said Ying Diao, an associate professor of chemistry and chemical and biomolecular engineering at the University of Illinois Urbana-Champaign and a researcher at the Beckman Institute for Advanced Science and Technology.

The study appears in the journal PNAS.

Synergy palladium single atoms and twinned nanoparticles for efficient CO₂ photoreduction

Posted by in categories: engineering, nanotechnology, particle physics

The challenge of regulating the electronic structures of metal single-atoms (M-SAs) with metal nanoparticles (M-NPs) lies in the synthesis of a definite architecture. Such a structure has strong electronic metal-support interactions and maintains electron transport channels to facilitate carbon dioxide photoreduction (CO2PR).

In a study published in Advanced Powder Materials, a group of researchers from Zhejiang Normal University, Zhejiang A&F University and Dalian University of Technology, revealed the engineering of the of Pd single atoms with twinned Pd nanoparticles assisted by strong electronic interaction of the atomic metal with the support and unveiled the underlying mechanism for expedited CO2PR.

“As one of the most promising CO2PR semiconductors, polymeric graphitic carbon nitride (g-C3N4) featured with sp2 π-conjugated lamellar structures can offer electronegative nitrogen atoms to anchor M-SAs, forming active metal-nitrogen moieties (M–Nx),” explained Lei Li, lead author of the study. “However, stable M–Nx configurations forbid tunability of electronic structures of M-SA sites.”
