An international team of scientists, including Polish researchers, has presented a new model of rapid quark-gluon plasma hydrodynamic expansion. This is the first description to take into account that the particles creating the plasma carry spin, that is, quantum rotation.
Non-locality, Einstein’s „spooky action at a distance”, has already been observed between quantum objects separated by more than one kilometer. This achievement is not a surprise – recent years have seen a major advancement in the quest for non-local systems. In their „Physical Review Letters” publication, researchers from the Faculty of Physics, University of Warsaw present a novel and versatile method for creating and detecting such correlations in a many-body system of ultra-cold atoms.
Researchers at the Faculty of Physics, University of Warsaw have developed a new cosmological model of the evolution of the Universe, in which rapid expansion of dark matter and dark energy plays a key role. The model predicts that we should soon register the original gravitational waves created in the first moments after the Big Bang.
Depending on the lighting, the surface of appropriately crafted nanoparticles can change its topography. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have shown that the molecular mechanism they have designed makes it possible, by the use of light, to effectively uncover or hide catalyst molecules. The technique they present leads to qualitatively new possibilities to control the course of chemical reactions.
There is no doubt: the immediate future of photovoltaics will be decided by materials from the perovskite group. An improved version of a perovskite, containing in the crystal structure a relatively large organic ion, a guanidinium cation, has been developed by chemists from the Institute of Physical Chemistry of the Polish Academy of Sciences and the Faculty of Chemistry of Warsaw University of Technology. Laboratory tests at the École Polytechnique Fédérale de Lausanne have shown that photovoltaic cells made of the new perovskite work more efficiently than the cells prepared using its original form.
It would seem that the structure of the human eye does not allow us to see infrared light. This is not entirely true! It turns out that we are able to see short laser flashes in the infrared range. Polish scientists were among the scientists who explained this phenomenon. Now they are looking for possible applications of this discovery.
Polymer for the production of aircraft fuselage covering, protecting airplanes against the effects of lightning strikes and cheaper than currently used solutions, has been developed by scientists from the Silesian University of Technology in Gliwice. Statistically, every airliner gets struck by lightning 2-3 times a year.
