Headline: Batteries: Modeling tomorrow's materials today

■ Release Date: 2024.5.21

■ Published by: Karlsruher Institut für Technologie (KIT)

■ Keywords: battery, cathode, sodium-ion

■ Abstract:

Which factors determine how quickly a battery can be charged? Microstructural models have helped researchers discover and investigate new electrode materials. When sodium-nickel-manganese oxide is used as cathode material in sodium-ion batteries, simulations reveal modifications of the crystal structure during charging. These modifications lead to an elastic deformation, as a result of which capacity decreases.

Headline: Promethium bound: Rare earth element's secrets exposed

■ Release Date: 2024.5.22

■ Published by: DOE/Oak Ridge National Laboratory

■ Keywords: rare earth, promethium, lanthanide

■ Abstract:

Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.

Headline: Researchers design new metal-free porous framework materials

■ Release Date: 2024.5.22

■ Published by: University of Liverpool

■ Keywords: hydrogen, catalysis, chloride ions

■ Abstract:

Researchers have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.

Headline: Under extreme impacts, metals get stronger when heated, study finds

■ Release Date: 2024.5.22

■ Published by: Massachusetts Institute of Technology

■ Keywords: metal, copper, spacecraft

■ Abstract:

Scientists have discovered that when metal is struck by an object moving at a super high velocity, the heat makes the metal stronger. The finding could lead to new approaches to designing materials for extreme environments, such as shields that protect spacecraft or equipment for high-speed manufacturing.

Headline: Scientists develop new battery-free lactic acid sensor

■ Release Date: 2024.5.22

■ Published by: University of Bath

■ Keywords: chemosensor, battery, graphene

■ Abstract:

Scientists have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power.

Headline: Electromechanical material doesn't get 'clamped' down

■ Release Date: 2024.5.23

■ Published by: Rice University

■ Keywords: electromechanical, antiferroelectric, lead zirconate

■ Abstract:

A new study finds that a class of electromechanically active materials called antiferroelectrics may hold the key to overcoming performance limitations due to clamping in miniaturized electromechanical systems.
