In this study, pure ZnO, CeO2 and ZnO/CeO2 nanocomposites were synthesized using a thermal decomposition method and subsequently characterized using different standard techniques. High-resolution X-ray photoelectron spectroscopy measurements confirmed the oxidation states and presence of Zn(2+), Ce(4+), Ce(3+) and different bonded oxygen species in the nanocomposites. The prepared pure ZnO and ...

A simple method for organically modifying a natural acid clay (Japanese clay) rapidly with alkylamine has been developed. Japanese mainly consists of acidic montmorillonite and was successfully modified decylamine in water at room temperature short time period (10 min) using an ultrasonic bath without any pretreatments. The structure the changed from exterior surface modification to intercalati...

Chemical modifications of clay to remove methylene blue (MB) from aqueous solutions at room temperature were compared. Natural bentonite (NC) was modified by cation exchange with hexadecyltrimethylammonium chloride (HC), bencyltriethylammonium chloride (BC), and tetramethylammonium chloride (TC) to reverse the surface polarity of the hydrophilic bentonite. The adsorption of MB was studied and f...

The morphological identification of Trypanosoma cruzi is currently considered to have a high specificity, but its sensitivity, which depends on the volume of the sample examined, is rather low. Trypanosome developmental stages suspended in blood, reduviid feces, and culture media are routinely searched for by means of fresh film examination (about 2 microL). High speed centrifugation of blood s...

Abstract The objective of this study is to explore the preparation and application sludge produced in plants drinking water treatment, remove methylene blue (MB) dye from polluted water. Adsorbate (methylene blue) prepared lab. as a stock solution. To create new adsorbents, chemical activation used has been carried out. performed by HCl H 2 O mixture . experiments were out under different bound...

Dyes such as batik dyes and the textile industry can pollute enviroment, especially receiving water bodies. The use of pineapple biomass waste an adsorbent for removal (methylene blue). Adsorption experiment using were varied in dose, contact time stirring speed. In this study, used consisted pure activated biomass. experimental result showed that masses into 0,5,1,2,5,3, dan 3,5 gr 250 mg/L gl...

Endodontically treated teeth are known to present a higher risk of biomechanical failure than vital teeth. Complete obturation of the root canal system to the cementodentinal junction is assumed to be an important goal in endodontic treatment. The microleakage is determined today by many in vivo and in vitro techniques such as; staining, measurement by scanning electron microscope, bacterial ac...
