Headline: Long-term consequences for Europe's climate ambitions when the EU turns off Russian gas

■ Release Date: 2022.8.1

■ Published by: Aarhus University

■ Keywords: gas, carbon-neutral 

■ Abstract:

The Paris Agreement and the climate ambition of a carbon-neutral EU in 2050 have been put back by the war in Ukraine. New research shows that the very high gas prices currently experienced by the Eurozone are actually a very efficient driver for the green transition.

Headline: Nickelate superconductors are intrinsically magnetic

■ Release Date: 2022.8.1

■ Published by: DOE/SLAC National Accelerator Laboratory

■ Keywords: nickelate, superconductors

■ Abstract:

Scientists embedded elementary particles called muons into a many-layered nickel oxide superconductor to learn more about its magnetic properties. They discovered that waves of flip-flopping electron spins create magnetic excitations that sweep through the nickel layer of the compound whether it's superconducting or not. This is in sharp contrast to what happens in the best-known family of unconventional superconductors, the cuprates, and offers another valuable clue to how these materials can carry electric current with no loss.

Headline: Researchers improve cement with shrimp shell nanoparticles

■ Release Date: 2022.8.2

■ Published by: Washington State University

■ Keywords: cement, carbon emissions

■ Abstract:

Putting nanoparticles from shrimp shells into cement paste made the material significantly stronger -- an innovation that could lead to reduced seafood waste and lower carbon emissions from concrete production.

Headline: Affordable and sustainable alternative to lithium-ion batteries proposed

■ Release Date: 2022.8.2

■ Published by: Rensselaer Polytechnic Institute

■ Keywords: lithium-ion, batteries 

■ Abstract:

Concerns regarding scarcity, high prices, and safety regarding the long-term use of lithium-ion batteries has prompted a team of researchers to propose a greener, more efficient, and less expensive energy storage alternative.

Headline: The bacteria powering a truly green revolution in personal electronics

■ Release Date: 2022.8.2

■ Published by: University of Massachusetts Amherst

■ Keywords: biofilm, electricity

■ Abstract:

Researchers recently announced that they have figured out how to engineer a biofilm that harvests the energy in evaporation and converts it to electricity. This biofilm has the potential to revolutionize the world of wearable electronics, powering everything from personal medical sensors to personal electronics.

Headline: Researchers 3D print high-performance nanostructured alloy that's both ultrastrong and ductile

■ Release Date: 2022.8.3

■ Published by: University of Massachusetts Amherst

■ Keywords: alloy, 3D 

■ Abstract:

Researchers have 3D printed a dual-phase, nanostructured high-entropy alloy that exceeds the strength and ductility of other state-of-the-art additively manufactured materials, which could lead to higher-performance components for applications in aerospace, medicine, energy and transportation.

Headline: New magnesium superionic conductor towards lithium-free solid-state batteries

■ Release Date: 2022.8.4

■ Published by: Tokyo University of Science

■ Keywords: magnesium ion, conductor 

■ Abstract:

Scientists demonstrate a metal -- organic framework-based magnesium ion conductor showing superionic conductivity even at room temperature.

Headline: Water can't touch this sanded, powdered surface

■ Release Date: 2022.8.4

■ Published by: Rice University

■ Keywords: sanded, superhydrophobic 

■ Abstract:

Scientists and engineers have developed a one-step method involving sandpaper and powder to make robust superhydrophobic materials.
