Project summary

The present level of scientific and technological progress is closely connected to a wide application of a new class of materials – that is nanosized systems. This fact is driven by a variety of new properties demonstrated by these materials in their various characteristics –– electrical, magnetic, optical, thermal, bactericidal, antiseptic, and others.

There are quite a few methods for producing this type of materials. But none of them allows to control the growth of the particles to the extent where nanoparticles of exact properties and compositions would be produced. Furthermore, most methods of obtaining nanosystems require special complex equipment, they are labor intense, and use earlier produced powders of required composition or mechanical mixes of inpidual components as raw materials for the synthesis.

This project seeks to develop an improved version of chemical precipitation method, referred to in the literature as the sol-gel method. Unlike the known method, which allows to produce ceramic materials, introduction of different variants of the reduction stage to the sol-gel method, significantly extends capabilities of the method allowing to produce metallic nanopowders of simple and complex composition with particular properties; allowing to produce salts, metal-ceramic and composite materials.

Presently, copper-based nanosystems have attracted attention of material engineers, because their application in many areas of technology is highly effective.

Purpose of the project: Develop optimal conditions for obtaining copper-based nanosystems with iron, tungsten, and cobalt additives from industrial wastes. Determine the relative impact of production process conditions on the properties of the final materials. Carry out a comprehensive study of the structure and properties of nanosystems. Determine the effectiveness of their application in inorganic materials and organic compounds. Select the elements to be included in the alloys and determine the optimal compositions according to the results of preliminary studies for specific applications: metal organic compositions of bactericides and antiseptics and high technology welding practice.

The following primary studies will be performed while the project is being carried out: study of several sources of raw materials; sequencing of the physical and chemical processes of obtaining copper-based nanopowders by the method of chemical dispergation for different sources of raw materials.

These studies are labor intensive and require a large number of experiments to: determine the optimum process parameters for preparing secondary raw materials containing copper used in the chemical dispergation processes; determine the parameters for the preparation of the elements in the alloys; determine the influence of the process under different conditions on the properties of nanopowders containing copper; study the influence of the concentration of the second component on the properties of nanopowders containing copper; as well as several other potentially important process parameters.

This project will work out the method for obtaining copper-based nanosized compounds by means of chemical dispergation. It will determine the physical and chemical regularities in obtaining nanosized compounds by the synthesis of organometallic compounds, complex compounds, which show pesticidal activity, and a whole array of compounds with other purposes.

The ability of industrial wastes to serve as raw material for the methods developed to obtain nanomaterials will be a significant result of the project. One of the project’s aims is to develop a solution for present, severe ecological problems.

The project includes implementation of following tasks:

· Establishment of the possibility to use the secondary raw material containing metal for obtaining the research intensive copper based nanopowders.

· Establishment of physical and chemical regularities of obtaining the copper based nanosized compounds by the chemical dispergation methods from industrial wastes.

· Establishment of physical chemical regularities of obtaining the nanosized metallic powders containing copper with different ratio of components during their obtaining by the improved sol- gel method

· Development of the method for obtaining the copper chloride nanosized powder.

· Development of the control over properties of copper based nanosized materials during production by the chemical dispergation methods.

· Obtaining the complex compounds, which possess pesticidal activity from the nanosized compounds containing metal.

· Establishing the efficiency of the copper based nanosized powdered materials application in the synthesis of organometallic preparations.

The main expected results are following:

· Developing a method for obtaining copper-based nanosized compounds using methods of chemical dispergation. Toxic industrial wastes such as the wastes from electrolytic production, pickling solutions, and wastes from metal products will be the source of raw material. The project, among other things, is directed towards the solution of ecological problems.

· Determining physical and chemical regularities of obtaining copper-based nanosized compounds using chemical dispergation methods.

· Determining physical and chemical regularities of obtaining copper-based nanopowders with particular properties and different ratios of components using chemical precipitation methods.

· Developing control over properties of copper-based nanostructured materials as they are obtained by chemical dispergation methods.

· Developing ways of using copper-based nanosized powdered materials in the processes of synthesizing organometallic compounds.

· Developing ways of obtaining complex compounds, which possess pesticidal activity, using nanosized components that contain metal.

· Creating a database of properties of copper-based nanomaterials.

Group of scientists for implementation of this project includes high quality specialists: professors and doctors.

The experience of those who have carried out the project in a particular field gives confidence that the project will be completed in a timely manner at a high scientific and professional level.

The project fully meets ISTC goals of redirecting the talents of military scientists toward peaceful aims in science.
