Ilya Anatolyevich Rodionov, candidate of technical sciences, director of FMN Laboratory based at Bauman Moscow State Technical University, tells about many of the latest developments and scientific areas, such as plasmonics and nanophotonics, SCULL technology, and the "Russian method" of teaching architects of the future.
Role of educational projects in the activities of a modern high-technology company DOI: 10.22184/1993-8578.2020.13.7-8.414.418
MAPPER LLC was founded as a subsidiary of the Dutch company MapperLithography. In 2012, 10 process engineers were hired, graduates of Russian universities, who spent 6 months in Holland to learn how to work with high-tech equipment and acquire skills in developing technological processes for the production of MEMS elements. Some of the employees had many years of experience in Europe and America even before their employment at MAPPER LLC. The production of MAPPER LLC was launched in 2014. Since then, the MEMS foundry has been continuously operating and supplying products to its customers. Simultaneously with production activities, the company is intensively developing internship programs and accepting students of technical schools and universities for practical training. Today we present an interview with Rod Irina Andreevna, Manufacturing Director of MAPPER LLC, dedicated to the discussion of the role of the educational programs in the high-tech company's activities, as well as results of the internship implementation.
Investigation of the side walls roughness effect of the Si3N4 lightguide layer of different thickness on optical losses in an integral waveguide formed on a quartz substrate DOI: 10.22184/1993-8578.2020.13.7-8.450.457
This article presents results of the influence of the side walls roughness of the 100 nm and 200 nm silicon nitride. Calculation of the main parameters of the side walls roughness of the lightguide layer, which have the greatest effect on the optical loss in the waveguide, carried out by finite difference time domain method (FDTD), is presented. Based on this calculation, the optimal thickness of the lightguide layer of nitride was established, allowing the light flow to be retained. Calculation of the model was based on the data obtained during the study of SEM images of manufactured waveguide structures. The results of these calculations are consistent with the data obtained using optical frequency domain reflectometry (OFDR) in the optical backscatter reflectometer (OBR) of manufactured waveguides with a thickness of silicon nitride 200 nm and width of 3 µm and 8 µm.
The structure of the appendages on spores of bacillus cereus DOI: 10.22184/1993-8578.2020.13.7-8.458.464
Bacillus cereus is a ubiquitous bacillus species. B. cerеus is known to cause various diseases, mainly associated with damage to the gastrointestinal tract (GIT) with symptoms of diarrhea and vomiting. B. cerеus can be an etiological agent of meningitis, pericarditis, pneumonia, eye diseases which accompanies wound infections. New data on the structure of outgrowths of B. cerеus bacteria are presented on the basis of the experimental data obtained with the aid of the transmission electron microscopy and computer image analysis.
Biomorphous neuroprocessor – prototype of a new generation computer being a carrier of artificial intelligence. Part 1 DOI: 10.22184/1993-8578.2020.13.7-8.466.475
A biomorphic neuroprocessor implements a hardware impulse neural network for traditional information processing tasks, as well as for reproducing the work of the cortical column of the brain. The key nodes of the hardware neural network are the memory and logic matrices, developed on the basis of a new component of nanoelectronics –
a combined memristor-diode crossbar, which have a high integration of elements and energy efficiency compared to known neuroprocessors and separate matrices. The concept of a biomorphic neuroprocessor, a description of a neural network built on the basis of an original software model of a neuron and adapted to the hardware of the neuroprocessor, as well as nanotechnology for manufacturing a memristor-diode crossbar and the results of a study of its electrophysical properties are presented.

Study of the absorption spectra of fluorocarbon coatings obtained with the aid of a LF-plasmatron at atmospheric pressure DOI: 10.22184/1993-8578.2020.13.7-8.442.448
The paper presents the results of studying the absorption spectra of fluorocarbon coatings obtained with the aid of a low-frequency plasmatron of a low-temperature atmospheric pressure plasma. The amplitudes of the absorption peaks are considered and the chemical composition of the coatings is established. The band gap is determined by the Tauz method.
Structure of the bacillus cereus sporules exosporium DOI: 10.22184/1993-8578.2020.13.7-8.426.432
In the environment B. cereus bacilli are adapted to the saprophytic lifestyle. Under certain conditions, they can become pathogens for humans and animals. The interest in B. cereus bacilli is due to the fact that they cause diseases of the gastrointestinal tract (GIT), and can also cause septicemia, endocarditis, pneumonia, meningitis, etc. An important stage in the life cycle of B. cereus is sporulation. B. cereus sporules have specific structures that are absent in vegetative cells, and are responsible for such sporule properties as thermal stability, resistance to various damaging factors, adhesion to biotic and abiotic surfaces. The data on the fine structure of the B. cerеus exosporium were obtained using transmission electron microscopy and computer image analysis.
Investigation of surface hardening effect on the local mechanical properties of the cutting tools working edge DOI: 10.22184/1993-8578.2020.13.7-8.434.441
In this work the mechanical properties of the punching die cutting edge were investigated by instrumental indentation. The near-surface layer of punching dies is modified in the process of mechanical action with a milling tool and local heating by a laser. Profiles of the hardness on depth have been constructed using the method of automated mapping. It was found that the processing of the tip by local laser heating leads to an increase in the hardness of the alloy by a factor of 1.5 in the region of about 40 μm.
