Self-decontaminating materials are defined as substances or objects designed and fabricated to deactivate pathogenic microorganisms or chemical warfare agents. Self-decontamination makes it possible for continuous protection against toxic materials. In order to develop destructive barriers against biological and chemical air pollutants, protective clothing and membranes using catalytic or enzym...

This paper is focused on microstructure of protective layers created by co-deposition of Al and Si on nickel base superalloys INCO 713 LC and INCO 738 LC after thermal and thermal-stress exposition and on microstructure of basic materials (substrates). The contribution also shows creep tests results for both superalloys with and without a protective layer.

The process of dental caries is determined by a delicate balance between pathological factors (bacteria and carbohydrates) that lead do demineralization and protective factors (saliva, calcium, phosphate and fluoride) that lead to remineralization. Contemporary approach to the treatment of dental caries includes preventive and prophylactic measures based on the notion of “demineralization and r...

This study aims to examine the performance of the rock materials in the protective layer of rubble-mound breakwaters in southern Iran, from Rostami Port in Bushehr Province to Beris Port in Sistan and Baluchestan Province. Field inspections were carried out on a great number of rubble-mound breakwaters built in the Persian Gulf and Oman Sea coastal regions to study the protective layer of these...
