Gold-MXene catalyst converts nitrate to ammonia using sunlight and 1.5 volts

Plants need nitrogen fertilizers, which are usually ammonia-based. Ammonia is therefore one of the most important chemical products. However, its production is currently extremely energy-intensive. An international team from ...

Bringing complex field physics to the tabletop: A photonic stage for non-Abelian gauge fields

For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain position, for example, it doesn't matter whether it's turned clockwise or counterclockwise—the result ...

Rare-earth ions could enable telecom-ready control of interacting qubits

Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and ...

Scientists demonstrate transition between strong and weak coupling regimes in a polariton microcavity

Researchers from Skoltech, together with colleagues from the N.D. Zelinsky Institute of Organic Chemistry and Westlake University, have experimentally demonstrated how the operating regime of a polariton laser changes with ...

How NASA plans to build the Habitable Worlds Observatory

We've been covering the journey of the Habitable Worlds Observatory for some time now. Over the past few years, it's gone from a proposal to a relatively fleshed-out plan for how and what the next Great Observatory should ...

Simple semiconductor films break light's front-back symmetry

Light typically interacts with a material the same way whether it enters through the front or the back—like polarized sunglasses that work the same from either side. Cornell researchers have demonstrated a simple route to ...

Highly tunable electro-optic isolator achieves one-way light flow on photonic chips

Integrated photonic devices—tiny circuits that use light instead of electrons—are becoming increasingly important for scalable photonics technologies and high-bandwidth communications. They are particularly valuable for managing ...

Physicists capture first direct evidence of a Floquet topological state

A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...

A quantum heat engine that simultaneously provides work and refrigeration

The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...

Quantum dots reveal hidden light waves on metal surfaces

Photographs can reveal things that are otherwise impossible for the naked eye to see, be they distant galaxies or microscopic cells. Researchers at Osaka Metropolitan University have developed a practical and versatile imaging ...
