Headline: Researchers find hints of a 'hidden state' involving one of Earth's most abundant ions

■ Release Date: 2023.1.3

■ Published by: University of California - Santa Barbara

■ Keywords: calcium, phosphate, phosphate ions

■ Abstract:

While conducting an otherwise straightforward investigation into the assembly mechanism of calcium-phosphate clusters, researchers made a surprising discovery: Phosphate ions in water have a curious habit of spontaneously alternating between their commonly encountered hydrated state and a mysterious, previously unreported 'dark' state. This recently uncovered behavior, they say, has implications for understanding the role of phosphate species in biocatalysis, cellular energy balance and the formation of biomaterials.

Headline: Researchers discover new process to create freestanding membranes of 'smart' materials

■ Release Date: 2023.1.3

■ Published by: University of Minnesota

■ Keywords: perovskite, semiconductors, nano-membranes

■ Abstract:

A team has developed a new method for making nano-membranes of 'smart' materials, which will allow scientists to harness their unique properties for use in devices such as sensors and flexible electronics.

Headline: Development of next-generation solid electrolyte technology, 'stable' even when exposed to the atmosphere

■ Release Date: 2023.1.3

■ Published by: DGIST (Daegu Gyeongbuk Institute of Science and Technology)

■ Keywords: lithium ion, battery, electrolyte

■ Abstract:

Engineers have announced the development of solid electrolytes with enhanced atmospheric stability.

Headline: A step towards solar fuels out of thin air

■ Release Date: 2023.1.4

■ Published by: Ecole Polytechnique Fédérale de Lausanne

■ Keywords: solar, hydrogen, fuel

■ Abstract:

Chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous, capable of harvesting water from the air for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare.

Headline: Cheap, sustainable hydrogen through solar power

■ Release Date: 2023.1.4

■ Published by: University of Michigan

■ Keywords: hydrogen, solar, panel

■ Abstract:

A new kind of solar panel has achieved 9% efficiency in converting water into hydrogen and oxygen--mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind.

Headline: More links aren't necessarily better for hybrid nanomaterials

■ Release Date: 2023.1.4

■ Published by: Rice University

■ Keywords: nanomaterials, semiconductor, light-activated materials

■ Abstract:

Chemists have discovered more isn't always better when it comes to packing charge-acceptor molecules on the surface of semiconducting nanocrystals.

Headline: New type of entanglement lets scientists 'see' inside nuclei

■ Release Date: 2023.1.4

■ Published by: DOE/Brookhaven National Laboratory

■ Keywords: gold ions, atomic nuclei, particles of light

■ Abstract:

Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC) to see the shape and details inside atomic nuclei. The method relies on particles of light that surround gold ions as they speed around the collider and a new type of quantum entanglement that's never been seen before.

Headline: Using machine learning to forecast amine emissions

■ Release Date: 2023.1.6

■ Published by: Ecole Polytechnique Fédérale de Lausanne

■ Keywords: carbon-capturing, amine, carbon dioxide

■ Abstract:

Scientists have developed a machine learning approach to accurately predict potentially harmful amine emissions from carbon-capturing plants.
