Cracking caused by cutting of plasma-sprayed hydroxyapatite coatings and its relation to the structural features of coatings deposited at different initial substrate temperatures
(Hemijska industrija, 2017)
The present study estimated the cracking phenomenon in as-plasma-sprayed hydroxylapatite coatings (HACs) after they were being subjected to the severe cutting conditions in the direction perpendicular to the coating/substrate ...
Decolorization of crystal violet over TiO2 and TiO2 doped with zirconia photocatalysts
(Hemijska industrija, 2017)
Titania based catalyst and TiO2 doped with zirconia were prepared by modified sol-gel method. The synthesized catalysts samples were characterized by BET, XRD, SEM and FTIR techniques. Photocatalytic activity was tested ...
Effects of water pretreatment on properties of pellets made from beech particles
(Hemijska industrija, 2021)
Particles of beech wood were treated with hot water at the temperature of 150oC, during 60 min, prior to the pelleting process. The applied hot water pretreatment affected the chemical composition and heating value of ...
