Conductance of an antiaromatic molecular circuit measured for the first time21.07.17

A collaboration of Japanese and Czech researchers has realized a molecular circuit involving an antiaromatic molecule for the first time. Antiaromatic molecules have 4n electrons in the π system. They had been predicted decades ago to have remarkable electron transport properties but their instability and difficult synthesis had prevented their study until now. In their paper published in Nature Communications, the authors explain the origin of this high conductance compared to the aromatic counterpart.

EU grant for the research on terahertz magnetic memories20.07.17

European research project coordinated by the Institute of Physics of the Czech Academy of Sciences was selected in a fierce competition within the Future and Emerging Technologies program that is part of the Excellence pillar of the Framework Programme Horizon 2020. The project ASPIN is based on a work published last year in Science which opened a new research and development direction towards ultrafast and energy efficient memories based on so called antiferromagnets.

Prestigious high-impact journal publishes a fundamental Czech study on grain boundary chemistry and material embrittlement10.05.17

Intergranular embrittlement is one of the most dangerous effects responsible for catastrophic failure of construction metallic materials. The reason is that it proceeds very quickly and its occurrence is hardly predictable. However, it is known that this problem is closely connected to chemical composition of intergranular regions – grain boundaries. Solutes and impurities tend to accumulate – segregate – at grain boundaries at enhanced temperatures in such an extent that they can occupy all available atomic positions there.

Scanning microscopes can determine the electronegativity of atoms04.05.17

A new insight into the characterization of chemical properties of the elements has been contributed by a method of Czech and Japanese researchers, published in the prestigious journal Nature Communications. State-of-the-art scanning-probe microscopes already enable scientists to resolve individual atoms on surfaces, but thanks to the new method, they can also measure the ability of these atoms to attract electrons, i.e. their electronegativity.

Livermore meets key milestone for delivery of world’s highest average power petawatt laser system 07.02.17

The High-Repetition-Rate Advanced Petawatt Laser System (HAPLS), being developed at Lawrence Livermore National Laboratory (LLNL), recently completed a significant milestone: demonstration of continuous operation of an all diode-pumped, high-energy femtosecond petawatt laser system.

With completion of this milestone, the system is ready for delivery and integration at the European Extreme Light Infrastructure Beamlines facility project (ELI Beamlines) in the Czech Republic.

Focus on the lightest atoms in the smallest crystals12.01.17

Scientists from the Institute of Physics of the CAS lead an international team, which developed a new method to analyze the scattering of electrons in nanocrystals. The method is so accurate that it can be used to detect the positions of even the lightest of all atoms – the hydrogens. The accuracy and reliability of the method was demonstrated in a publication, where hydrogen positions were determined in two different materials. The work was published in the journal Science in its January 13th, 2017 issue.

Advanced DPSSL laser, "DiPOLE 100", delivers 1kW performance27.12.16

"DiPOLE 100" (alias "Bivoj"), a fully diode pumped solid state laser (DPSSL) designed and constructed at STFC's Central Laser Facility (CLF) at Rutherford Appleton Laboratory, was delivered under contract to the HiLASE Centre in the Czech Republic. In mid-December 2016, it achieved its full design performance, operating at an output energy of 100 J per pulse at 10 Hz (1 kW) for over 1 hour without operator intervention.

EC to fund Czech-British partnership for a "next generation" laser centre for industrial applications24.11.16

The European Commission has officially announced that is to co-fund the creation of a new "Centre of Excellence" (CoE) for the industrial exploitation of new laser technology in partnership with the Czech Ministry of Education, Youth and Sports. Scientists from Czech Institute of Physics and the STFC's Central Laser Facility in Oxfordshire, UK, will work together on the 5.5 year / 45 MEuro project. This is the first time to be funded under the "Widespread Teaming" programme within Horizon 2020 that aims to improve the innovation performance of Member states.

Resolving transformations of molecules and their chirality in the submolecular scale22.11.16

Scientists from the Institute of Physics and the Institute of Organic Chemistry and Biochemistry of Czech Academy of Sciences observed a chemical transformation of individual molecules on silver surface and demonstrated chirality transfer during the reaction. They employed the latest advances of scanning probe microscopy, which allows scientists to determine the chemical bond between individual atoms within molecules and thus determine their molecular structure and the chirality. The results were published in the prestigious journal Nature Chemistry.
