The junction is the key: Researchers decrypt transport dynamics of porous media
What laws govern how chemicals pass through filters? How do droplets of oil move through layers of stone? How do blood cells travel through a living organism?
02-Dec-2022
A team of researchers led by the Technical University of Munich (TUM) and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) has discovered how pore space geometry impacts transport of substances through fluids. Concentration takes energy. As you read this article, the blood ...
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 ...
The memory of folds
What happens when soft materials are compressed strongly?
28-Jul-2021
Researchers from the Max Planck Institute for Dynamic and Self-Organization, the University of Twente and Cornell University now revealed the morphology of creases created upon folding at micrometer scale. They revealed a dual folding mechanism driven by capillary forces, similar to wetting ...
Soft matter on new ways to self-organization
The groove of the self-organized active nematic ribbon
29-Sep-2020
Nematic materials, such as the liquid crystals in our displays, contain molecules that align themselves in parallel. When they are constructed from microtubules and kinesins, materials found in our cells, they become active and move and deform without the supply of energy from the outside. In a ...
Attraction or Repulsion?
Interactions of chemically active particles can be as complex as human relationships
24-Apr-2020
Researchers at the Max Planck Institute for Dynamics and Self-Organization show that two microscopic non-equilibrium chemically active particles, such as enzymes or catalytically active colloids, can have a vast range of complex interactions reminiscent of human relationships, instead of just ...
How living matter self-organizes through chemical signals
Scientists show new mechanism of self-organization of living matter
08-Jul-2019
Cells and microorganisms produce and consume all sorts of chemicals, from nutrients to signaling molecules. The same happens at the nanoscale inside cells themselves, where enzymes catalyze the production and consumption of the chemicals needed for life. In new work published in Physical Review ...
Small droplets grow differently
Initially, there is an unexpected growth spurt when droplets grow from moisture condensing on a surface
03-Sep-2012
Fine dew drops on spider webs, blades of grass, and even insects can lend them breathtaking beauty. And, examining them very closely, one recognises that the drops themselves form astonishingly regular and aesthetic patterns. For the first time, scientists at the Max Planck Institute for Dynamics ...
Turbulence around heat transport
07-Dec-2009
Not only in the Earth's mantle, in the atmosphere and in the outer layers of the Sun, but also in a chemical reactor, the exchange of heat may not be as effective as originally thought. There, because warm fluid rises and hence induces movement, the turbulent convection can be 100 billion times ...
