Matter exists in different phases. Some of them, such as the solid, liquid or gaseous phase, we can distinguish with the naked eye, while other phases of matter can only be distinguished by cleverly devised experiments. Examples of such phases are the magnetic and non-magnetic phases, or the superconducting and non-superconducting phases. At our site, we will show the different ways we can reach the transitions between phases, and the interesting physical phenomena associated with them, and, during a tour of the laboratory, we will learn how matter and its transformation can be studied using state-of-the-art instruments.

The story of semiconductors, laced with the discovery of the laws of the microworld so different from ordinary human experience, has resulted in a fundamental transformation of our understanding of the world and in an equally fundamental transformation of the world itself. Artificial structures based on semiconductors now make it possible to store and process previously unimaginable amounts of information, but also to retrieve and remotely transmit previously unimaginable amounts of information in the form of various sensors and detectors. It is only thanks to semiconductors that artificial light has ceased to be an energetically expensive rarity.

We can describe the world around us with just a few dozen physical equations. Some of these describe phenomena we experience daily, which might seem somewhat dull. However, there are equations that, even on paper, evoke awe, and their application brings mostly fear. Come and learn more about humanity's encounter with the most terrifying transformation in physics.

Suitable for older children and adults: 12+

Puzzles, quizzes, identification games... As always, you can test your astrophysical knowledge with the help of our students.

A program change from previously planned Mix Your Own Space Drink! – The exact nature of many celestial objects remains a mystery. However, we have simulations that give us a rough idea of what to expect. Come and create your own model of a celestial object—it's up to you whether you follow our suggested recipe or make your own. The only condition is that you must drink your model! The provided ingredients will be non-alcoholic.

A relaxing session with a projection of the most beautiful space images and animations. And who knows, it might just turn into a spontaneous lecture.​

he plasma chemistry laboratory at the Department of Plasma Physics and Technology focuses on innovative plasma technologies and equipment for surface treatment of materials. In the framework of the Night of Scientists 2024 we would therefore like to present several prototypes of plasma sources and examples of their practical use in the laboratory as well as with our industrial partners from all over the world. In addition, we will be happy to explain how plasma surface treatments of various materials are realized and why plasma technologies are attractive to the industry. We will also experiment with several materials and measure the effect of plasma treatment.

How to make an ordinary mobile phone almost unbreakable? How to transform ordinary glasses into anti-reflective and self-darkening? How to turn cheap jewels into gold jewellery? How to reduce fuel consumption and boost car performance? The answer is thin films. How thin are they? Where can you find them? How can they be produced? Visit the scientists at the Institute of Plasma Physics and Technology to find out how they are changing the world.

The electron microscope perfectly displays transformations that are too small for the human eye. The limescale formed in a pipe is different from that in a kettle. A swarf has shapes far more elegant than a machined piece of iron, an eggshell does not resemble a feather, and pollen does not resemble a seed. And what about technological transformations! Thin layers on cutting tools are abraded, plasma-activated surfaces are not entirely smooth, and graphene and graphene oxide are brothers who are as different as siblings can be. Come and see for yourself.

We can view the transformations in detail using an electron microscope. Have you ever seen a 3D image from an electron microscope? Our machine can do it. Come watch and marvel at what nature and skilled human hands can do. Enjoy breathtaking glimpses into the microworld in the comfort of a guided screening.

Screening with live commentary starts at 7PM and 9PM at lecture room F1.
