Scientists from the Institute of Physics of the Czech Academy of Sciences in collaboration with their Korean colleagues successfully demonstrated an experiment to create and destroy solitons with non-integer charge. They achieved this by using electrical pulses from the tip of a scanning microscope. The new procedure is an important step in the development of quantum computers based on solitons. The result was published in the Nature Nanotechnology journal.
Until now, observing subatomic structures was beyond the resolution capabilities of direct imaging methods, and this seemed unlikely to change. Czech scientists, however, have presented a method with which they became the first in the world to observe an inhomogeneous electron charge distribution around a halogen atom, thus confirming the existence of a phenomenon that had been theoretically predicted but never directly observed.
This year’s Rudolf Lukeš Prize awarded by the Czech Chemical Society goes to physicist Pavel Jelínek
An international independent committee has awarded the Rudolf Lukeš Prize for 2020 to Pavel Jelínek for his research of chemical properties of molecular structures on solid surfaces. It was the scanning microscopy techniques being developed with the potential to find application in organic chemistry that captured attention of the assessors.
Czech scientists in collaboration with their colleagues from Spain introduced a new type of polymers which have been unavailable by means of traditional methods applied so far. This polymer type could play an important part in the design of new components for nanoelectronics, such as new displays.
Czech scientists have contributed to the development of a new class of single-dimensional organic conductors
A joint work by Czech, Spanish and Swiss scientists published by Nature Nanotechnology this week, introduces a new approach to the development of non-metallic conductors which could be used in solar energy, optical technologies or nanoelectronics.
Czech Researchers Discovered a New Way of Controlling Magnetic and Electronic Properties of Molecules
This may open new doors for developing novel optical sensors, photoluminescent materials, catalysts, and pharmaceuticals.
Hydration of ions on surfaces is of great importance, for example, in corrosion, electrochemistry, or transport of ions in living organisms.
A collaboration of scientists has made significant progress in imagining water molecules. This work opens the way for studying the internal structure and dynamics of ice or water on the surface of solids.
A new microscopic method concerning the probe with the flexible terminal atom/molecule enables for the first time direct observation of the chemical structure of individual molecules.
New measuring method overcomes the insufficiency of previous Kelvin Probe Force Microscopy (KPFM). Thus it significantly advances our current possibilities to study the charge transfer at the atomic level.
Recent developments in scanning microscopy enable us to resolve the chemical structure of individual molecules deposited on surfaces.
Scientists from the Institute of Physics of the ASCR, together with colleagues from Spain and France, presented in the journal Nature Communications new theory of the origin of polyaromatic hydrocarbon molecules in the universe. According to the new theory, these molecules are formed by hydrogen etching of the graphitic surface of the stardust particles.
