What do atomic nuclei really look like? Are the protons and neutrons they contain distributed chaotically, or do they bind into clumps made up of two protons and two neutrons? Polish physicists from Kraków and Kielce present predictions for several light nuclei.
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.
Smartphone-sized devices capable of purifying water for one person using sunlight; desktop modules producing substances valuable for the pharmaceutical industry from chemical waste. The construction of such innovative instruments, providing the product not in batches but continuously, is becoming possible thanks to an ultrasonic technique of depositing titanium dioxide layers onto the inner walls of tubes with diameters of even micrometre dimensions.
