Thermal stabilisation of poly(vinyl chloride) by organotin compounds
The effect of LSN 117 (dioctyl tin bis isooctyl thioglycollate, an organotin compound) on the heat stability of plasticised PVC was investigated in this study. The organotin stabiliser had carbonyl and carboxylate groups ...
CO2 and N2 adsorption on the acid (HCl, HNO 3, H2SO4 and H3PO4) treated zeolites
CO2 and N2 adsorption on the acid treated natural and synthetic zeolites at 5◦C and 25◦C was studied. The system heterogeneity was higher for CO2 than N2 adsorption and decreased with acid treatment.
Investigation of HA cement preparation and properties by using central composite design
(Trans Tech Publications, 2012)
The goal of the present work was to investigate the effects of several cement preparation parameters on setting and hardening reaction mechanisms and hydroxyapatite (HA) cement properties. A central composite experimental ...
Effects of surface functional groups on the aggregation stability of magnetite nanoparticles in biological media containing serum
Size stability of magnetite nanoparticles (MNP) with different surface functional groups in biological media was achieved by the addition of fetal bovine serum (FBS). The stability of the particles was attributed to the ...
