If antimatter is like a mirror image of matter, why is the Universe full of matter, and not antimatter? Scientists in their experiments find only slight differences between matter and antimatter. The biggest differences still elude them. Prof. Mariusz Witek from the Institute of Nuclear Physics PAS talks about this with PAP.
We do not have to look for dark matter here and now, for example in particle detectors. Traces of interaction of dark matter with ordinary matter can survive in millions of years old geological samples. You just need to know how to look for them, researchers including a Polish scientist suggest.
The Polish concept of time crystals will be realized in Australia for the first time in the world. A method of creating such crystals was developed in Kraków by Prof. Krzysztof Sacha. Thanks to particles reflected by atomic mirrors, scientists will study solid state physics from a completely new perspective.
5, 10, or maybe 15? How many nanometers should nanoparticles of a catalyst measure to optimise the course of reaction? Researchers usually perform laborious tests to find the answer. Scientists at the Institute of Physical Chemistry PAS a new technique to improve the process of such optimisation in microfluidic systems. The size of catalyst nanoparticles can now be changed as needed during a continuous flow through the catalyst bed.
When chemists from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw were starting work on yet another material designed for the efficient production of nanocrystalline zinc oxide, they didn't expect any surprises. They were greatly astonished when the electrical properties of the changing material turned out to be extremely exotic.
Some isomeric states of superheavy elements may have half-lives measured in seconds, tens of thousands of times longer than the half-lives of their very unstable ground states. If such exotic nuclear states are experimentally produced, they will be stable enough to study their chemical properties.
Researchers from the Institute of Physics of the Polish Academy of Sciences demonstrated a new physical phenomenon: routing the emission of light using transverse magnetic field. This is a step towards avoiding the "bottleneck" that limits the development of fast information processing devices.
