Do you have a problem finding out how much you really weigh, because the bathroom scale shows a slightly different result every time you step on it? Scientists from the ALICE experiment at CERN determined the mass of the charm quark - an elementary particle that weighs about half a million billion billionth part of gram and is released only for a fraction of a second at huge temperatures in the collisions of particles inside the Large Hadron Collider.
Water is a fantastic liquid that has inspired scientists for centuries, and despite intensive studies of its complex nature, it still evades full understanding. When two droplets are brought together, they eventually settle into each other, merging and forming a larger, yet simpler, structure—a bigger droplet, while uniformly mixing. The same happens in foams, where tiny bubbles connect and eventually form larger bubbles. These phenomena occur because water tends to minimize its surface energy. A new study conducted by researchers from the Institute of the Physical Chemistry, Polish Academy of Sciences, led by dr. Guzowski shows how droplets, instead of merging, unexpectedly form increasingly complex structures. Let's take a closer look at their discovery.
They are everywhere, around us and within us. Phenomena lasting trillionths of a second form the core of chemistry and biology. It is only recently that we have begun to try to accurately record their actual course, with moderate success. However, physicists from Cracow have proven that the new window to the world of attophysics can be built, offering a very promising view.
How many nanometers should nanoparticles have to exhibit antibacterial properties, or be used in cancer treatment? Scientists from the Jagiellonian University and the Polish Academy of Sciences showed that the parameters of newly synthesized silver nanoparticles allow to tune their biological activity.
Scientists from the University of Warsaw, the Military University of Technology and the University of Southampton presented a new type of tuneable microlaser emitting two beams. The precisely tunable laser can be used in many fields of physics, chemistry, medicine and communication.
A group of scientists from the United States and Professor Krzysztof Sacha from the Jagiellonian University have just presented groundbreaking achievements in the work on time crystals, as reported by Nature Communications. Time crystals are structures that have only been studied for 10 years, which, like space crystals, have atoms arranged in repeating, predictable patterns, but in time. They can probably be used to recreate various components, such as superconductors or transistors.
Fragments of the interior of a proton have been shown by scientists from Mexico and Poland to exhibit maximum quantum entanglement. The discovery, already confronted with experimental data, allows us to suppose that in some respects the physics of the inside of a proton may have much in common not only with wellknown thermodynamic phenomena, but even with the physics of... black holes.
