Title of Speech: Stable and cost effective noble metal colloids (Ag, Au, Pt, Pd, alloys, etc.) formation by nontoxic ecofriendly PVD process
Abstract: Stable, cost effective, high purity noble metal (Ag, Au, Pt, Pd, alloys, etc.) colloid in liquid or solid was fabricated by nontoxic ecofriendly PVD process. The metal colloid were formed on the various solid powder such as functional fine ceramics: Al2O3, TiO2, SiO2, etc., soluble powder in polar or non-polar solvents; glucose, vitamin C, Vitamin B3, NaCl, NaHCO3, etc. and thermoplastics: PC, PE, PP, PTFE, etc. Vaporized metal from bulk raw metal were nucleated on the powder substrate in which the powder in vessel were stirred in a physical vapor deposition system, and the nano sized metal nuclei were fabricated and accumulated on the powder without coarsened and grown to thin films. The fabricated solid state metal colloids were very stable, and easily disperse in polar solvent( water, ethanol ,etc.) to form a liquid colloids and stable colloids in polymer by hot melting process without using any special dispersive agents. Functional colloids (Ag: antibacterial preservative, Au: anti-aging additives and thermotherapy effect, and Pt: antioxidant) were singly or simultaneously added into various cosmetics, and characteristic colors of cosmetic compounds were not changed at high concentrations of 100’s ppm, at high temperature and with long term periods. The colloids were analyzed by TEM, SEM, ICP-AES and UV-Vis spectroscopy, etc. More than 95% of the particles have sized 3-10 nm for Au, 2-3 nm for Pt, 3-5nm for Pd, and 5-15 nm for Ag. Colors of Ag colloid on various powders are changed from yellow to dark yellow with concentration, but colors of Au colloid are varied from violet to red due to surface plasmon resonance of nano size particles with interaction of powder substrate. The characteristic colors of the solid state colloid on the powders were not changed at all at various reservation environments. The SPR peak of Au on the glucose were changed near 550 nm and the peak of Ag 400 nm, respectively, by analyzing UV-Vis spectra. Because of stability, low cost, fine dispersion, high purity, simple process, etc., the process was expanded to synthesize various mineral colloids such as Zn, Fe, Cu, etc. and mixtures with the noble metal colloids have been applied to minerals for livestock and horticulture crop in agriculture products and adopted to produce various bio products of silkworms in entomology. Productivities, taste, residual amount of nanoparticles in the final products, and future directions were discussed in terms of toxicology, efficiency of minerals, comparison with conventional chemicals, etc.

Title of Speech: Formation and Interface Control of Polymer Films by Physical Vapor Deposition
Abstract: Organic materials are drawing attentions to hold the key for developing electronic devices in the next generation. Above all, polymers have advantages in thermal and mechanical stability as well as in flexibility. Thin films of polymers have been conventionally prepared by wet-processes using solutions of polymer materials. However, the wet processes frequently encounter problems in controlling multilayer structures of sub-micron-thick films. In this presentation, we propose several processes to form polymeric thin films by vapor deposition techniques. Normal polymers cannot be vaporized by thermal evaporation. Our strategy is based on synthesizing polymer thin films on the substrate by vapor-depositing small molecules.
On the other hand, it is also important to control the interface at organic/inorganic junctions due to incommensurate nature of these materials. We propose to alleviate the problems of organic/inorganic junctions by tethering the interface via covalent chemical bonds. This was achieved by use of self-assembled monolayers combined with the vapor-deposition polymerization technique. It is also possible to improve the interface with the aid of ion irradiation effect in the film deposition process. The covalent tethering is effective in improving charge injection at the organic/inorganic junction as well as in improving the adhesion strength and morphology of the organic layer. The ion irradiation can also be utilized to form functionally-graded polymer thin films.

Title of Speech: Nanotechnology and Nanoinocculant in Steel Metallurgy
Abstract: The scientific, technological and industrial revolution leads to a strong need for a parallel advanced processes and materials that can satisfy the fast development overall the world. Among the different areas of development come the engineering science and technologies as a tool for manufacturing, processing and a source for producing new and advanced innovated materials. In the recent years much advancements in the field of materials science and technology have been recognized and supported the development plans in most of the sectors and thematic areas, where there is no area without need of specific and special materials .Among these materials that are of great importance for the human been life and a main parameter in the human civilization comes metallic materials in general and steel alloys in particular. From the above mentioned we can conclude that the development strategy and plan depend to large extent on the materials properties and qualifications. Severe working conditions, complicated needs and properties, which are required from the specific materials, forced the researchers and scientists to modify currently used alloys and to invent new alloys and manufacturing techniques to obtain the required materials properties. Overall the world, in Bulgaria and particularly in Egypt the metal and steel industries are growing fast to meetthe technological requirements. Most of the industrial and scientific firms and institutions work hard to produce new innovative and advanced steel materials using multiple alloying techniques. These techniques depend on the alloying of steel using specific alloying elements as chromium, nickel, molybdenum, tungsten etc. to obtain specific properties to the produced alloys. These metals are very expensive and lead to increase of the price of the produced alloys in addition to the technical problem, raised from the difficulty at their further processing as forming and heat treatment. Another technical problem comes from the increased strength of the produced alloys (which is required for the applications) as increasing the strength results in a parallel decrease in the ductility and toughness of the alloys. These problems lead to lowering the quality and productivity of the industrial firms which will be reflected on the future of this industry in Egypt and Bulgaria. Many small and medium foundries face many of these problems especially at production of high alloyed expensive grades of steel (as Mn highchromium high-nickel alloyed steel).A new trend in this field is to improve the properties of steel alloys through grain refinement by receiving of new crystallization centres. This method involvesso-called in-situ formation of crystallization centres as well as introduction of crystallization centres, which are nanosized particles of refractory compounds. In-situ technique uses micro additions of specific alloying elements that have the power to produce fine nitride, carbide and carbonitride precipitates in the nano size as titanium (Ti), vanadium (V) and/ or niobium (Nb). This technique was applied in many steel plants for all production scale; the results were not as expected for steel castings which form the main production of foundries. Large amount of the added alloying elements (Ti, V and/ or Nb) is lost by oxidation or form a sold solution within the metallic matrix. Formation of non metallic inclusions forms one of the expected problems that lead to quality problem in the produced parts.
