Year 2016 outputs
Results of the research groups for 2016
Microscopy and Spectroscopy of Surfaces
• It has been demonstrated that scanning electron microscopy with extremely slow electrons can determine the number of graphene layers in both reflection and transmission modes, and the graphite surface can be cleaned.
Microscopy and Microanalysis
• A methodology has been developed to enable the scanning electron microscope to show the growth of composite non-conducting nano-layers in native state without prior coating.
Microscopy for biomedicine
• Developed methodology for the preparation of cryogenically cooled samples of microbial cultures and their biofilms were applied to scanning electron microscopy (eg bacteria-produced polymers, morphological changes in stressed yeast cells)
• The Group is actively involved in the project Research Infrastructures Czech-Bioimaging, which is considered as the national partner of the Euro-Bioimaging project.
• A substantially expanded version of the quantum-mechanical behavioral simulation of bound and relaxation nuclear spin systems NMRScopeB
• MR measurement of diffusion in the transgenic mouse model of Parkinson's disease was performed and processed and evaluation of the multiparametric model has shown that diffuse kurtosis can be used as an alpha-synuclein accumulation indicator accompanying this disease, and is therefore a potential objective marker for this disease in the early stages.
• A rapid MRI measurement method has been developed and validated to quantify the distribution of fat and water concentration, which can be used, for example, in the diagnosis of liver disease.
• Methods and software solutions for medical signal processing were represented by Open SignalPlant, a platform for visualization and analysis of large signals and a cardiac arrhythmia detection program. SignalPlant is expanded in 68 countries and is used primarily for ECG and EEG analysis.
• Enhancement of a full-body impedance monitor designed to monitor blood distribution and pressure wave propagation to allow simultaneous measurement of signals from up to 18 body locations in different hemodynamic states.
• We continued to analyze the functional organization of the epileptic hippocampus.
Environmental Electron Microscopy (EREM)
• We used new equipment and applied developed EREM imaging methods to various live specimens, eg somatic embryos of the fir, and the display of plant biological samples in the native state was compared to low-temperature EREM, Cryo-SEM and optical confocal microscopy. Optical micromanipulation techniques
• We have demonstrated the existence of a hypothetical power contribution from the optical spin.
• Theoretically and experimentally, we analyzed the effect of cubic potential on the behavior of the stochastic system, which leads to an increase in the signal / noise ratio.
• We identified the concentration of polymers in microorganisms by Raman microspectroscopy.
Coherent Lasers and Interferometry
• Analysis of non-classical light from a large set of chilled ions Ca.
• Pilot testing of the automated gauge calibration system at the Metrological Institute.
• Share on the realization of the 306 km long backbone connection of the national photon network of the Czech Republic, which transports the superstatic wavelength of the so-called normal laser from the ÚPT AV ČR laboratories in Brno to CESNET in Prague.
• Utilization of photonic optical fibers filled with absorption gases in metrology of lengths.
Cryogenics and Superconductivity
• Methods for measuring the emissivity and absorbency of highly reflective surfaces in the range of 20–300 K and the radiation properties of materials and coatings for space use have been developed and verified.
• Within the framework of the development of space apparatus, the contracting contracting research body determined the emissivity and absorption of various metal surfaces and metallic layers in the temperature range of 25 K to 320 K
• Participation in COMPASS experiments.
• Planar Au / Fe / Au nanostructures have been designed and prepared to be used as perspective magnetic field sensors.
• The fracture toughness of the nanolaminated coatings was evaluated using the indentation and impact tests
• The deposition technique of deposition of niobium nitride superconducting coatings of hundreds of nanometers strong with a critical temperature Tc comparable to Tc of the bulk material was developed.
• STEM / TOF electron-optical systems have been optimized for very low electron energies Electronic lithography
• The method of detecting the current density in electronic electron beam lithographs has been improved.
• A diffraction imaging device was designed whose individual diffractive elements are arranged in a non-orthogonal coordinate system using a phylotactic model.
• Technology for the preparation of Si3N4 structured Si3N4 thin films on silicon mats usable as SEM electron diffraction masks has been developed.
• Development of brazed and welded joints for special industrial applications, eg electronic nozzles and electron microscope parts, zirconium alloy joints, hermetic bushings for nuclear power plants, parts for the automotive industry.
• Developing a gas flow analysis in the welding process by the Schlier method.
• Application of the method of monitoring the laser welding process by means of a mathematical analysis of radiation behavior induced by laser-induced plasma.
