Headline: Optical rule was made to be broken

■ Release Date: 2022.9.12

■ Published by: Rice University

■ Keywords: nanophotonic, pyrite, semiconductor

■ Abstract:

Engineers find a way to identify nanophotonic materials with the potential to improve screens for virtual reality and 3D displays along with optical technologies in general.

Headline: Making mini-magnets

■ Release Date: 2022.9.12

■ Published by: University of Tsukuba

■ Keywords: tin telluride, insulator, ferromagnetic

■ Abstract:

Researchers demonstrated a topological insulator device that opens the way towards observing the quantum anomalous Hall effect. Because the currents generated are resistant to scattering, but very sensitive to applied magnetic fields, they may be used for reducing power consumption in computing applications.

Headline: Environmental scientists develop a method to turn hazardous acidic industrial wastewater into valuable resources

■ Release Date: 2022.9.13

■ Published by: Ben-Gurion University of the Negev

■ Keywords: phosphoric acid, industrial fertilizers, industrial wastewater

■ Abstract:

Environmental scientists have developed a circular process for eliminating the risk posed by phosphoric acid plant wastewater. The process turns the environmentally toxic wastewater into clean water while recovering valuable acids. Phosphoric acid is the main ingredient in industrial fertilizers, a massive industry worldwide.

Headline: Shallow-water mining is not a sustainable alternative to deep-water mining, scientists argue

■ Release Date: 2022.9.13

■ Published by: Cell Press

■ Keywords: Shallow-water, deep-water, mining

■ Abstract:

Shallow-water mining projects are already underway in Namibia and Indonesia, and projects have been proposed in Mexico, New Zealand, and Sweden, but the effects of these projects haven't been fully investigated. Scientists argue that shallow-water mining needs more rigorous environmental evaluation before it can be declared safe and sustainable.

Headline: Nanorattles shake up new possibilities for disease detection

■ Release Date: 2022.9.13

■ Published by: Duke University

■ Keywords: gold, nanorattle, disease detection

■ Abstract:

Researchers have developed a unique nanoparticle called a 'nanorattle' that greatly enhances light emitted from within its outer shell. Loaded with light scattering dyes, the approach can amplify and detect signals from separate types of nanoprobes without needing an expensive machine or medical professional to read the results. In a small proof-of-concept study, the nanorattles accurately identified head and neck cancers through an AI-enabled point-of-care device that could improve global health.

Headline: Precise control of catalytic reactions

■ Release Date: 2022.9.14

■ Published by: Pohang University of Science & Technology (POSTECH)

■ Keywords: magnetic material, catalysts, nanoreactor

■ Abstract:

A team develops a nanoreactor combining magnetic material and plasmonic catalysts. Remote control of step-by-step catalytic reactions of precursor led to cinnamaldehyde product with 95% yield.

Headline: Scientist discovers new oxidation state of rhodium

■ Release Date: 2022.9.14

■ Published by: University of Freiburg

■ Keywords: rhodium, platinum-group, converter

■ Abstract:

Chemists have discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group metals and is used, for example, in catalytic converters for automobiles. Rhodium is actually already well-studied.

Headline: Paving the way for large-scale, efficient organic solar cells with water treatment

■ Release Date: 2022.9.15

■ Published by: GIST (Gwangju Institute of Science and Technology)

■ Keywords: solar, cell, active layer

■ Abstract:

Using water for morphology control of active layer thin films, researchers develop large-area, high-performance organic solar cells.
