Slim steel - strong and safe

A material made from a few readily available components is very strong in tension and is nevertheless highly formable

31-Jan-2023

Until now, developers of steels have had to make a choice: Either they increase the tensile strength of the material and usually accept that their material becomes relatively brittle. Or they rely on the fact that the steel can be strongly stretched and thus absorb a lot of energy in the event of ...

Elegant experiments with light

Researchers find a new way to make use of Photoredox Catalysis

27-Jan-2023

Scientists of the department of Homogeneous Catalysis have found a new elegant way to make use of photoredox catalysis. Researchers of the Max-Planck-Institut für Kohlenforschung have expanded the molecular toolbox for efficient, targeted syntheses: To do so, they use a very special catalyst - ...

Quantum simulator enables first microscopic observation of charge carriers pairing

Research results could be key to understanding high-temperature superconductors

23-Jan-2023

A team of researchers at the MPQ has for the first time monitored in an experiment how holes (positive charge carriers) in a solid-state model combined to form pairs. This process could play an important role in understanding high-temperature superconductivity. Using a quantum simulator, ...

Researchers cast new light on magnons to verify topological phases in magnetic materials

“Raman scattering is a standard experimental technique available in many labs, which is one of the strengths of this proposal”

19-Jan-2023

Much recent research has focused on ‘topological’ materials – an intriguing type of solids which fall outside the standard classification into insulators and conductors. While their bulk is insulating, these phases are characterized by electrically conducting channels which appear at their edges. ...

Why optical cavities curb the rate of chemical reactions

“This works puts the controversial field of polaritonic chemistry onto a different level”

23-Dec-2022

Chemical processes are all around us. From novel materials to more effective medicines or plastic products – chemical reactions play a key role in the design of the things we use every day. Scientists constantly search for better ways to control these reactions, for example to develop new ...

With light into the nanoworld: How optical microscopes allow detailed investigations of nanoparticles

The goal: the development of novel nanoparticles for biomedical applications.

21-Dec-2022

It sounds like trying to scan a vinyl record with a hammer: Light is actually too "coarse" to image small particles on the nanometer scale. However, in their project "Supercol"- funded by the European Union - scientists want to achieve just that: The investigation of nanoparticles with light. To ...

New aspects of surface wetting revealed

Findings may thus enable developing new strategies for surface processing

16-Nov-2022

When a surface is getting wet, also the composition of the liquid plays a role in the wetting process. Researchers from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) found that phase separation within the wetting liquid directly affects the dynamics of spreading. Their ...

Max Planck spin-off develops more efficient batteries

Batene starts with ten million euros in seed financing

16-Nov-2022

An invention by researchers at the Max Planck Institute for Medical Research could make batteries much more energy dense, efficient and safer. The research team has found a way to produce very fine metal fleeces, the batene fleece, that can serve as current collectors in batteries and make them ...

Battery research - First online database on photocharged materials developed

Data was extracted from scientific articles published in the past 40 years and now is available in the form of interactive graphs online

31-Oct-2022

Dr. Aleksandr Savateev, group leader at the Max Planck Institute of Colloids and Interfaces, has developed a unique online database. To do so, he has analyzed and standardized research data from 300 papers published over the past forty years in the field of photocharged semiconductors. The ...

Discovering new materials with the help of machine learning

International research team publishes universal framework in the journal Science

12-Oct-2022

Novel materials are the key for our transition to a more sustainable economy. However, the search for and design of new materials matching specific technology requirements are time and cost-intensive. Especially for high-entropy alloys that are solid solutions of multiple principal elements, the ...
