Detecting aniline in air in systems based on piezoelectric quartz crystal resonators modified with poly(ethylene glycol succinate) under static and dynamic conditions
(Journal of Analytical Chemistry, 2000)
The optimal conditions have been found for aniline sorption on a film of poly(ethylene glycol succinate) by the piezoelectric quartz crystal microbalance method using bulk acoustic wave sensors based on AT-cut quartz ...
Study of chlorination of nickel silicate by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
The paper presents a thermodynamic analysis and experimental research on the kinetics of the chlorination of nickel silicate (2NiO x SiO2) by gaseous chlorine and calcium chloride without additives and in the presence of ...
Thermal investigation of two FePO materials prepared in the presence of 1,2-diaminoethane
(Elsevier, Amsterdam, 2000)
Two porous iron phosphates were synthesized hydrothermaly from a reaction mixture of FeCl3:H3PO4:1,2-diaminoethane:H2O in the molar ratio 1:3:5:70. The chemical formulas indicate difference only in water content; however, ...
Study of quantitative structure-retention relationships for s-triazine derivatives in different RP HPTLC systems
(Akadémiai KiadóSpringer, 2005)
Quantitative structure-retention relationships (QSRR) have been used to study the chromatographic behavior of some s-triazines. Retention factors, RM0, on C18 layers corresponding to zero percent organic modifier in the ...
Decomposition of methomyl over supported iron catalysts
(Springer, Dordrecht, 2007)
Catalytic wet peroxide oxidation of methomyl over Fe-ZSM-5 and AlFe-pillared montmorillonite was carried out at room temperature, in a glass batch reactor, under constant airflow and halogen lamp light. Both catalysts have ...
Levels of PAHs in the soils of Belgrade and its environs
(Springer, Dordrecht, 2007)
Polycyclic aromatic hydrocarbons (PAHs) were analysed in 39 soil samples (0-10 cm upper layer) collected in Belgrade, the capital of Serbia. The sampling sites were randomly selected from urban, urban/recreational and rural ...
Scaling of network segment dimensions in hyperelastic composites
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The change in elastomer tensile moduli, as formulated in the Gaussian statistical theory of rubber elasticity, with deformation, is considered both experimentally and theoretically. Gum elastomers of different structures ...
Indentation damage detection in thermoplastic composite laminates by using embedded optical fibers
(Journal of Advanced Materials, 2005)
In recent years, optical fibers have received attention as sensors for the purpose of in-service health monitoring in composite materials. Advantages of optical fiber sensors over conventional sensing methods are well-known ...
Investigation on the static and fatigue failure of bi-directional composite pipes
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The process of filament winding is particularly suited to the manufacturing of composite pipes. This paper first describes the overall process and its advantages for composite structures. Particular attention is devoted ...
Electrophoretic deposition of boehmite coatings on titanium from aqueous sols
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The electrophoretic deposition from sots and colloidal suspensions of ceramic powders has many advantages over conventional ceramic powder processing methods. In this way it is possible to control the thickness and ...
