Many antimicrobial coatings deliver a peak release of antimicrobial agent at an early age, after which they lost antimicrobial activity over time. In the present study a novel geopolymer paints with long term antimicrobial activity were developed bas

Heat treatment of flint and other knappable materials has been recognized among prehistoric archaeological lithics, leading to a wide range of experiments and archaeometric analyses. The aim of these analyses was to shed light on the mechanical and c

The present study focuses on the adsorption of Pb(II) by the H-form of titanosilicates (ETS-4, GTS-1) and clinoptilolite. The H-forms were prepared by first exchanging the extra-framework cations—Na+, K+, Ca2+, etc.—with NH4+, and by subsequent t

Geopolymers based on Bulgarian natural zeolite (clinoptilolite) were synthesized using alkaline activators in order to prepare plaster/render mortar. The influence of the alkali concentrations of the activator solution was examined in regard to tensi

Coal-combusting power plants are simultaneously among the main emitters of carbon dioxide and the main generator of solid by-products, such as fly ash (FA). An attempt to find a common solution for these environmental problems is reported in the pres
