the silver spr chip was modified by alkaline-silane condensation with aminopropyltriethoxysilane (aptes) in naoh aqueous solution at different times. silver sputtered slides coated with aptes were immersed in naoh solution, enabling us to produce silver surfaces homogeneously covered with aptes. the surface properties of grafted aptes on sputtered silver surface as a occasion of time were studi...

Humic acid (HA) impairs water quality due to its reactivity with many substances present in water. During the drinking-water treatment process and distribution via supply system, HA may react chlorine other disinfects <br /> producing harmful disinfection by-products (DBPs), which are categorized by International Agency for Research on Cancer (IARC) groups 2A (probably carcinogenic humans...

In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...

Objective: The aim of the present study was to assess the bond strength of universal cements cured either dually or chemically only. Methods: Three cements were assessed using different types of application: dual activated (DA) or chemically activated (CA). In total 80 dentin blocks were used, obtained through the enamel wear of the lingual and buccal surfaces of bovine incisors. Standard cone-...

glassy carbon (gc) is the most commonly used carbon-based electrode in the analytical laboratory. because of the high background current and low electrode response, modification of this electrode can be done by various materials and techniques. an ionic liquid (il), 1-methyl-3-(3-trimethoxysilyl propyl) imidazoliumbis (trifluoromethylsulfonyl) imide, was covalently cross linked onto the gc surf...
