Terahertz radiation still cannot be used practically, although it could find applications in medical diagnostics, communication or security. Research conducted with the participation of Polish scientists gives a chance for building new radiation sources.
If it were possible to observe neutrinoless double beta decay, it would be tantamount to the discovery of a new elementary particle - a Majorana-type particle. Such a finding would be as momentous as the discovery of the Higgs boson. Researchers are getting closer to this discovery, as reported in Science.
Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications. Using silicon carbide as an example, physicists from Cracow and Warsaw have shown that even such computationally demanding defects can be successfully examined with atomic accuracy by means of a cleverly constructed, small in size, model.
Lithium fluoride crystals have recently been used to register the tracks of nuclear particles. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have just demonstrated that these crystals are also ideal for detecting tracks of high-energy ions of elements even as heavy as iron.
Materials as lightweight and resistant as plastic, yet fully biodegradable and... created from waste? Scientists from the Institute of Physical Chemistry PAS are working on an ecological, waste-free and economical method of obtaining organic monomers.
Textbooks need an update? Diamond, graphene, graphite, fullerenes (and nanotubes) are no longer the only known forms of carbon! Carbon was observed in another form: cyclocarbon, an atomic size carbon ring. A Polish researcher has contributed to the discovery described in "Science".
The mass of particles is not given once and for all! It depends on the environment and can change, even in conditions such as those that prevail in collisions of neutron stars, researchers confirmed in the HADES experiment. The study sheds new light on where particles get mass.
A fractal is an object, a fragment of which looks similar to the whole when enlarged. Fractal structures have already been discovered in proteins, mountain ridges, signal from the stock exchange, sunspots and even Jackson Pollock`s paintings. Prof. Paweł Oświęcimka talks about what physicists are looking for in fractals.
