Headline: Technology could boost renewable energy storage

■ Release Date: 2024.9.16

■ Published by: Columbia University School of Engineering and Applied Science

■ Keywords: electrolyte, energy storage, renewable

■ Abstract:

Renewable energy sources like wind and solar are critical to sustaining our planet, but they come with a big challenge: they don't always generate power when it's needed. To make the most of them, we need efficient and affordable ways to store the energy they produce, so we have power even when the wind isn't blowing or the sun isn't shining.

Headline: In step toward solar fuels, durable artificial photosynthesis setup chains two carbons together

■ Release Date: 2024.9.17

■ Published by: University of Michigan

■ Keywords: photosynthesis, ethylene, gallium

■ Abstract:

A key step toward reusing CO2 to make sustainable fuels is chaining carbon atoms together, and an artificial photosynthesis system can bind two of them into hydrocarbons with field-leading performance.

Headline: A smoother way to study 'twistronics'

■ Release Date: 2024.9.17

■ Published by: Harvard University

■ Keywords: graphene, twistronics, boron nitride

■ Abstract:

A new article describes a fingernail-sized machine that can twist thin materials at will, replacing the need to fabricate twisted devices one by one.

Headline: Flexible circuits made with silk and graphene on the horizon

■ Release Date: 2024.9.18

■ Published by: DOE/Pacific Northwest National Laboratory

■ Keywords: graphene, protein, silk

■ Abstract:

Ultra-thin layers of silk deposited on graphene in perfect alignment represent a key advance for the control needed in microelectronics and advanced neural network development.

Headline: Breakthrough in hydrogen research

■ Release Date: 2024.9.19

■ Published by: Universität Leipzig

■ Keywords: hydrogen, energy, isotope

■ Abstract:

Hydrogen is in great demand due to its promising role as a sustainable resource in the energy transition. Researchers have made an important breakthrough in the efficient and cost-effective provision of isotopes. These are the three forms in which hydrogen occurs in nature -- as protium, deuterium or tritium. The team has taken a big step towards realizing its dream of separating hydrogen isotopes at room temperature at low cost.

Headline: Low-carbon ammonia offers green alternative for agriculture and hydrogen transport

■ Release Date: 2024.9.19

■ Published by: RMIT University

■ Keywords: ammonia, hydrogen, energy

■ Abstract:

A new way of making ammonia by harnessing the unique power of liquid metal could lead to significant cuts in carbon emissions caused by production of the widely-used chemical. Ammonia is used in fertilizer to grow much of our food, but also plays a role in clean energy as a carrier to safely transport hydrogen.

Headline: Innovating alloy production: A single step from ores to sustainable metals

■ Release Date: 2024.9.19

■ Published by: Max-Planck-Gesellschaft

■ Keywords: alloy, metal, ore

■ Abstract:

Scientists design a process that merges metal extraction, alloying and processing into one single, eco-friendly step.

Headline: Revolutionary visible-light-antenna ligand enhances samarium-catalyzed reactions

■ Release Date: 2024.9.19

■ Published by: Chiba University

■ Keywords: samarium, antenna, catalyst

■ Abstract:

Divalent samarium compounds are important reagents for reductive transformations in organic chemistry. However, currently, a high amount of this reagent is required in most reactions, and it also necessitates the use of harmful chemicals. To address this issue, researchers have developed a visible-light-antenna ligand that coordinates with stable trivalent samarium compounds, which, upon exposure to visible light, are reduced to divalent samarium, enabling milder conditions and smaller amounts of samarium for reactions.

Headline: BESSY II: Heterostructures for spintronics

■ Release Date: 2024.9.20

■ Published by: Helmholtz-Zentrum Berlin für Materialien und Energie

■ Keywords: graphene, cobalt, iridium

■ Abstract:

Spintronic devices work with spin textures caused by quantum-physical interactions. Scientists have now studied graphene-cobalt-iridium heterostructures at BESSY II. The results show how two desired quantum-physical effects reinforce each other in these heterostructures. This could lead to new spintronic devices based on these materials.
