New solution for bionanoscopy based on the optical microlens technology DOI: 10.22184/1993-8578.2021.14.5.292.297
The microlens microscopy is a relatively new and promising solution to overcome the optical microscopy diffraction limit. It is possible to obtain the optical images with a resolution of tens nanometers using the spheres made of barium titanate. Moreover, combining the probe and microlens microscopy makes it possible to register a wide range of physical and biochemical parameters of the studied samples spectra. The great advantage of this method is a possibility to study a biomaterial either using labels and markers or not, which is essential. This is unattainable by many other conventional research methods. The use of a copper-vapour laser in an optical scheme, makes it possible to study biological objects at low light intensity.
Evolution of radiation effects in sub-microelectronic devices and test facilities DOI: 10.22184/1993-8578.2021.14.5.298.310
We provide a brief evolution trends overview of the modern sub-microelectronic devices and its radiation behavior, focusing on new structures and materials. Evolution of test facilities is also considered.
Recording holographic diffraction grids using a pulse laser DOI: 10.22184/1993-8578.2021.14.5.312.319
This paper deals with a device for holographic diffraction gratings (HDG) recording using a pulse laser, which makes it possible to increase the accuracy of grating and its diffraction efficiency. For this purpose use was made of the interferometer for recording gratings and an optically connected second source of coherent radiation located at the input. Such configuration eliminates the need to track corrections during illumination due to a short exposure period. A synchronization unit was introduced into the optoelectronic circuit which output was connected to the second source of pulsed coherent radiation, and the input – to the AC voltage source of the optoelectronic circuit.
Analysis of the mechanical properties of the materials for dental structures after artificial ageing DOI: 10.22184/1993-8578.2021.14.5.260.269
The study of the dental structures mechanical properties behaviour after simulated ageing processing at long-term use is the main feature of the presented paper. The paper contains the test results for 3D printed materials and for the other ones manufactured by milling of workpieces. The hardness and elastic modulus were measured by the nanoindentation method, the linear wear and friction coefficients were measured by the abrasion resistance method, and the elastic modulus, strength and deformation were determined by three-point bending method.
The world’s first scanning probe microscope as a satellite a new stage of the scientific satellite laboratories DOI: 10.22184/1993-8578.2021.14.5.270.274
In this paper we proposed a new stage of the experimental methods for various sciences as exemplified by the world’s first scanning probe microscope (SPM) designed as a satellite, i.e., taking out experiments out of the Earth laboratories directly in space to make them satellites complete with instrumentation and a set of objects to be studied.
Automated search for nanoparticles in the probe microscope images using a neural network DOI: 10.22184/1993-8578.2021.14.5.276.280
There are a number of important advantages that can be obtained by using automated search for objects detected by the probe microscopy, such as a high rate of data processing, minimization of experimentalist’s influence on the measurement process and a possibility to enlarge the data volume to be processed. It has been shown in this work that for the search for nanoparticles, which dimensions are comparable to a noise level, the more accurate result is achieved by a neural network algorithm based on protein nanoparticles data processing which was obtained using the atomic force microscopy while the larger nanoparticles are more precisely distinguishable by the threshold algorithm.
