Cu2+ plays an important role in biological and environmental systems and is extensively involved in the regulation of numerous biological processes in the human body. Our project proposes to prepare a multi-band emission fluorescent probe which has a wellseparated dual emission signal and is expected to achieve more accurate detection of Cu2+ ions through changes in the fluorescence ...

The results of research carried out by the authors on cleaning the metal surface of the propeller from corrosion using the technology of reverse-jet cleaning (RJC) using bentonite clay are presented. The presence of a protective film coating, formed in the process of processing according to the RJC technology, was established.

In this project, the blue green fluorescent carbon nanomaterials with rich functional groups will be prepared by hydrothermal synthesis technology, using natural biomolecular bovine serum protein as precursor BSA@CDs . A new type of carbon nano coated silver nanoclustered composite was further prepared by using CDs as template (CDs@AgNCs). The prepared CDs was used as template ...

In this paper, the machinability of cast iron is considered. Cast iron is an alloy of iron with carbon (and other elements), in which the carbon content is at least 2.14 % (the point of ultimate solubility of carbon in austenite in the diagram of states), and alloys with a carbon content of less than 2.14 % are called steel.In our work, special attention is paid to the machinability ...

This paper presents the results of comparative investigations of the efficiency of the process of magnetic-abrasive processing (MAP) of metal using various ferromagnetic abrasive powder materials. It is shown that diffusion-borated iron-based powders provided an increase in the productivity of the MAP processing. In addition, the new powders showed a higher service life compared ...

The article describes the capabilities and advantages of the developed adaptive learning management system "Scorina", which uses artificial intelligence to build a flexible and adaptive educational trajectory, taking into account the individual needs of students. The developed and implemented mathematical models and algorithms are briefly described.

Atherosclerosis is one of the main causes of cardiovascular and cerebrovascular diseases. According to statistics, cardiovascular and cerebrovascular diseases kill as many as 17.9 million people every year. In this paper, a real human blood vessel modeling method is proposed. The blood flow model obtained from this method can be used for vascular surgery training, planning and ...

Porcine respiratory disease（PRDC）is a common but difficult to cure problem in current large-scale pig farms. It is clinically manifested as multi-pathogen mixed infection or secondary infection. The pathogen is mainly viral infections such as Mycoplasma pneumonia (Mpr) and Mycoplasma hyorhinis (Mhr). Combined with other bacteria secondary or mixed infection. This article reviews ...

In this paper, the interface compatibility of ABS fiber is studied by mechanical testing and SEM analyzer. ABS fiber treatment adopts physical and chemical methods. Experiments show that ABS fiber is beneficial to mechanical properties and impermeability.

The problem of a healthy lifestyle in modern society today is one of the most urgent. The culture of a healthy lifestyle acts as one of the main components of the general culture of a person. An important issue of the aspect of studying a healthy lifestyle among young people are bad habits that lead to a decreasing the level of responsibility of young people for conserving their ...
