Headline: Switching to hydrogen fuel could prolong the methane problem

■ Release Date: 2023.3.13

■ Published by: Princeton University, Engineering School

■ Keywords: hydrogen, fuel, methane

■ Abstract:

Hydrogen is often heralded as the clean fuel of the future, but new research suggests that leaky hydrogen infrastructure could end up increasing atmospheric methane levels, which would cause decades-long climate consequences.

Headline: Scientists transform algae into unique functional perovskites with tunable properties

■ Release Date: 2023.3.13

■ Published by: Technische Universität Dresden

■ Keywords: perovskite, lead halide, electro-optical

■ Abstract:

Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.

Headline: New AI model transforms understanding of metal-organic frameworks

■ Release Date: 2023.3.13

■ Published by: Ecole Polytechnique Fédérale de Lausanne

■ Keywords: hydrogen, metal, transformer

■ Abstract:

Researchers have developed a new AI model that significantly improves the understanding of Metal-Organic Frameworks (MOFs), promising materials for hydrogen storage and other applications.

Headline: 3D internal structure of rechargeable batteries revealed

■ Release Date: 2023.3.13

■ Published by: Lancaster University

■ Keywords: battery, energy storage, lithium-ion

■ Abstract:

Researchers have pioneered a technique to observe the 3D internal structure of rechargeable batteries. This opens up a wide range of areas for the new technique from energy storage and chemical engineering to biomedical applications.

Headline: Game-changing high-performance semiconductor material could help slash heat emissions

■ Release Date: 2023.3.14

■ Published by: West Virginia University

■ Keywords: semiconductor, thermoelectric, ceramics

■ Abstract:

Solar cells made from metal halide perovskites achieve high efficiencies and their production from liquid inks requires only a small amount of energy. Scientists are investigating the production process. At the X-ray source BESSY II, the group has analyzed the optimal composition of precursor inks for the production of high-quality FAPbI3 perovskite thin films by slot-die coating. The solar cells produced with these inks were tested under real life conditions in the field for a year and scaled up to mini-module size.

Headline: Perovskite solar cells from the slot die coater -- a step towards industrial production

■ Release Date: 2023.3.16

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

■ Keywords: solar, cell, perovskite

Headline: Modelling superfast processes in organic solar cell material

■ Release Date: 2023.3.16

■ Published by: University of Groningen

■ Keywords: polymers, solar, cell

■ Abstract:

In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.

Headline: Stalactites and stalagmites in the battery?

■ Release Date: 2023.3.17

■ Published by: Max Planck Institute for Polymer Research

■ Keywords: solid-state battery, lithium, cell

■ Abstract:

They are considered the 'Holy Grail' of battery research: so-called 'solid-state batteries'. They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult to ignite and can also be manufactured on a miniature scale. Scientists have now turned their attention to the life cycle of such batteries and targeted processes that reduce it. With their findings, more durable solid-state batteries could be realized in the future.
