Opis:: In this paper we present the results of dielectric measurements of liquid crystal (LC) 5*CB arranged in porous matrices with a pore diameter of 100 and 20 nm. We analyse the effect of the surface interactions on the dynamics of the molecules. The results are compared with the results for bulk 5*CB. The most important observation is the blocking of the phase transition of 5*CB into the solid phase in the matrix with pore diameter of 20 nm.

Opis:: In this study, 1.2333 cold work tool steel and cast iron (GG 25) were simultaneously melted in different furnaces to fabricate composite die mold used in sheet metal forming industry. To enhance the metallurgical bond between two components of composite part, the pouring temperature of cast iron was assessed just above the solidus temperature, then metallurgically prepared cast iron was poured on to the cast tool steel. The temperature and casting parameters were monitored and simulated. Experimental and simulation results were compared, finally the optimum parameters and casting route were revealed.

Opis:: We report on the Czochralski method for single silicon crystal growth and discuss heat and mass transfer and defect formation in the crystal. A reflector was used for separation of the heating and cooling areas in the furnace enabling us to speed up crystal growth. The melt flow to stabilize the temperature distribution in a crucible was controlled using transverse magnetic fields in a large-scale silicon Czochralski furnace. The setup allows for changes in important parameters of point defect formation to be made, such as vacancies and interstitials, by changing temperature and flow fields in the furnace. A numerical calculation was developed to predict the tendency for growth of a vacancy rich or interstitial rich crystal by estimating the value of the ratio between the growth rate and temperature gradient in the crystals.
