Material substitution: artificial intelligence helps in the search for alternatives

Intelligent system searches scientific publications for substitutes for critical raw materials, e.g. in batteries

11-Jun-2025 - Lack of security of supply, excessively high prices, technical optimization, bans: There are many reasons why companies have to replace individual raw materials or materials with others. The search for alternatives is time-consuming and often ends in failure. A research team from Fraunhofer IPA ...

Fresh iron from old mining sludge

Great interest in pilot plant

06-Dec-2024 - It sounds like utopia: mining sludge is transformed into valuable metals and new building materials. Over the past three years, researchers at TU Bergakademie Freiberg have successfully trialled this innovative process in a pilot plant. The team succeeded in extracting iron and zinc from mining ...

Surprise at the grain boundary

For the first time, an international research team has been able to observe how solute elements introduce new grain boundary phases using state-of-the-art microscopy and simulation techniques

31-Oct-2024 - Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium. They were in for a surprise: “Iron atoms not only segregate to the interface, but they form entirely unexpected ...

Researchers unlock the “silicate magic” for safer, cheaper, and more efficient batteries

Xiaowei Teng leads team eyeing new way of using iron to create high-performance energy storage

22-Oct-2024 - The world is rapidly transitioning to renewable power, but there are shortcomings. Solar power falls at night, and wind power recedes and ascends irregularly. New technologies need to be developed that can store energy from the electrical grid when there’s a surplus and deploy it when there’s not ...

How catalysts remove dangerous nitrogen oxides

”If we know exactly where the reaction takes place, the production of catalysts can be controlled accordingly”

11-Oct-2024 - Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual iron atoms sitting in certain neighbouring ...

Iron as an inexpensive storage medium for hydrogen

Chemical process is similar to charging a battery

02-Sep-2024 - Researchers at ETH Zurich are using iron to store hydrogen safely and for long periods. In the future, this technology could be used for seasonal energy storage. Photovoltaics are set to meet over 40 percent of Switzerland’s electricity needs by 2050. But solar power isn’t always available when ...

On the way to sustainable chemistry? Iron makes it possible

Hydroformylation of olefins using iron catalysis and light

22-Jul-2024 - The hydroformylation of olefins, also known as oxosynthesis, is one of the most important industrial processes in chemistry. Developed in 1938 by Otto Roehlen (Ruhrchemie), more than 10 million tons per year of so-called oxo products are now produced using this process. The main catalysts used ...

Unravelling the secrets of artificial photosynthesis

Junior research group led by Dr Jacob Schneidewind launches new project on hydrogen production

05-Jul-2024 - "Our common goal is to develop artificial chloroplasts and use them to perform photosynthesis in order to produce hydrogen," says Dr Jacob Schneidewind from Friedrich Schiller University Jena. The idea is to utilize as broad a light spectrum as possible and to use inexpensive starting materials. ...

Will the climate transition be a battle of materials?

Heavy additional demand for commodities like cobalt, lithium, copper, aluminium and iron: Countermeasures include behavioural changes in mobility, housing and nutritin

06-Jun-2024 - As things stand today, global demand for cobalt and lithium for e-car batteries will increase almost twenty-fold by 2050. By then, the development of a fossil-free power supply will require a lot of copper, aluminium and iron, and the respective demand is likely to roughly double. Rare earth ...

What if a common element rather than scarce, expensive ones was a key component in electric car batteries?

Iron could be key to less expensive, greener lithium-ion batteries

28-May-2024 - A collaboration co-led by an Oregon State University chemistry researcher is hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries. The findings, published in Science Advances, are important for ...
