Surface of metallic and polymeric materials often needs to be engineered in order to meet some specific requirements. Surface properties are important because they determine the use of materials in their life cycle.
The most frequently engineered surface properties are hardness, wear and corrosion resistance, ductility, toughness, as well as some sophisticated ones, as e.g. self cleaning ability, antimicrobial and biocompatible properties etc But big problem is when many of these properties are needed to be in the same time, in the same part and in the same exploitation conditions.

In case when the treated tool/part should satisfy only one peculiar characteristics, the engineering procedure is not so complex. But, in general cases the machine parts/tools should satisfy more than one specific property, and this makes the surface engineering a real challenge.
How to do that?
With combination of more new technologies.  Usually, surface modification is applied to valuable (expensive) materials. Such materials are applied for the whole product, or only for its surface, while the bulk material should satisfy only a limited criteria and is not necessarily expensive one. Surface engineering on polymers

In the last decades, the most frequently used materials are different types of steel, but polymers are well make a progress as materials for industrial applications for tools, parts etc. Modification of the surface of polymeric materials has attracted particular scientific interest. In doing so, one can better take advantage of polymer materials attractive bulk properties (e.g. strength to weight ratio, transparency, thermal stability, easy processing). Modifying the surface of polymers can improve a number of their properties, as e.g. chemical, wear and abrasive resistance, hardness, etc. Plasma nit riding, also called ion nitrating or glow discharge nitriding, and PVD coatings, individually, or in combination are some of the new advanced surface treatment processes for improving the surface properties of the materials.
These plasma technologies, among the other, are one of the best technologies for improving the surface properties and contribute to the significant increasing of the hardness, wear resistance, corrosion resistance, abrasive resistance, and reduction of the coefficient of friction – resulting in prolonged use of the tools and spare parts for many times.The process is not toxic and responds to all modern requirements of environmental control. Tools of deep extraction, pressing, cutting and tinning Medical tools and instruments, tools for metal pipes, welding pipes and etc. Tools and parts for products of ceramics, bricks, roof tiles, and non-metal materials, plastic.

Tools for plastic deformation of metals, and more other none mentioned parts and tools.
Automobile parts Machine parts Molds of casting of Aluminum and other, non-ferrous metals or alloys under pressure, tools for extrusion Al, Cu and the other non-ferrous metals, Principal reasons for nitriding: to obtain high surface hardnessto increase wear resistance to improve fatigue life to improve corrosion resistance (except for stainless steel where corrosion resistance is the same) to obtain a surface that is resistant to the softening effect of heat at temperatures up to the nitriding temperature

Lowcost solar cells

Challenge
Power supply in the whole region of South ­East Europe is insufficient and this problem is foreseen to come at a critical point in the next period for developing countries, especially for Balkan’s countries. There are not enough possibilities for energy supply from neighboring countries, so all the efforts should focus on reinforcement of domestic energy resources and implementation of renewable energy sources (RES), especially increasing the exploitation of environmental compatible low­cost domestic RES like the photovoltaics

Solution
A possible alternative on silicone solar cells are 3D nanostructured solid­state solar cells, the low­cost photovoltaics, which are considered as a promising technology having the potential to significantly decrease the costs of solar energy. They have attracted considerable interest of the scientific and production community due to their low­energetic production cost and low­cost of the raw materials, which offer the perspective of very low­cost fabrication. Also, their deposition does not ask application of sophisticated technologies, as in the case of silicon solar cells, and they can be integrated in present industrial processes. These solar cells are comprised of an interpenetrating network of n­type and p­type semiconductors on a nanometric scale. In this type of solar cells, CuInS2 (CIS) is used both as light absorber and hole transport layer, and is deposited inside the pores of mesoporous film of TiO2. Performances of the solar cells should be sensitive by the size of used TiO2 particles, the thickness of the nanostructured TiO2 and CIS layers and effectiveness of the buffer In2S3 layer.

Applications (existing / potential)
The aim is deposition, characterization and parametric study of nanostructured solar cells based on TiO2/CIS, obtaining more efficient photovoltaic systems. Strengthening the knowledge for nanostructured solar cells and new technologies for their application, as well as improving collaboration between industrial companies and the research team for development of new technological processes.

Technical feasibility of product deriving from R&D
The experimental development of the production procedure and the characterization of nanostructured solar cells in laboratory conditions will allow introducing new and unconventional photovoltaic technologies that can find direct application in existing industrial processes. The research will allow direct cooperation between the research centre and industrial companies and enable partnership in the implementation of these technologies. This will directly grant application of the scientific research in the manufacturing process and it will provide a connection of the scientific institutions, on one hand, and the industrial subjects, on the other hand, which can be potential users of the results of the research.
