Researchers from the Institute of Physical Chemistry PAS in Warsaw have removed the main obstacle in the development of SERS - an extremely sensitive laboratory method of chemical composition analysis. Researchers have developed new substrates, onto which samples for analysis are applied.
To crack the nucleus of an atom, you must do what you do when cracking a nut - hit it with something. If you deliver enough energy, the forces binding the components of the nucleus will no longer be sufficient to keep it together, says particle physicist Prof. Grzegorz Wrochna.
A new method of separation of dextrorotatory and levorotary chiral molecules (molecules that are mirror images of each other) has been developed by an international group of scientists, including researchers from the Institute of Physics of the Polish Academy of Sciences. The results of their research have been published in Science.
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.
