In the present work, a novel magnesium based scaffold with a specific two-layer structure was prepared for powder metallurgical process.
The inner compact structure reinforced by the salt particles can increase the strength of the material.
Therefore, it is suggested here that the magnesium-based scaffold with a specific two-layer structure, namely, a porous structure in the outer layer and a compact reinforced structure in the inner layer, might be one of promising substitute materials for bone transplantation.

On the Defect Structure and Transport Properties of NiS2 Z.
Mrowecc AGH University of Science and Technology, Faculty of Materials Science and Ceramics, Department of Solid State Chemistry, al.
Because of considerable experimental difficulties, the defect structure of NiS2 has not been elucidated so far.
The lack of information, concerning defect structure and transport properties of disulphides of iron, cobalt and nickel, results from extremely low rates of their formation.
The aim of the present paper is an attempt to utilize this apparatus in studying the sulphidation kinetics of NiS to NiS2 as a function of temperature and sulphur vapor pressure, in order to get preliminary information on the defect structure and transport properties of NiS2.

Application of the electrochemical microcell technique in solid state surface analysis Halina Krawiec AGH-University of Science and Technology, Faculty of Foundry Engineering, Department of Chemistry and Corrosion of Metals, ul.
Glass capillaries with an extremely small diameter were used in biology [5], analytical chemistry [6, 7], electrochemistry and corrosion [1, 8, 9].
The use of small capillaries (diameter below 10 mm) has revealed that the most active place in AZ91 alloy is the eutectic structure.
