2010 WILEY-VCH Verlag Gmb The synthesis of colloidal nanoparticles (NPs) possessing hollow or core/shell structures has attracted a great deal of attention because these materials exhibit unique physical and chemical properties that allow them to be used in catalysis and drug delivery. These particles are typically produced using sacrificial templates, such as polystyrene or silica. Nevertheles...

This paper deals with propionic acid extraction by Aliquat 336, a quaternary amine dissolved in ndodecane and 1-decanol. Chemical equilibrium experiments have been carried out to investigate the effect of modifier, 1-decanol on the extraction efficiency of Aliquat 336 in ndodecane at fixed initial acid concentration of 0.27 gmol/l. Extraction efficiency is determined in terms of distribution co...

An analog of adenosine triphosphate, adenylyl imidodiphosphate (AMP-PNP), in which a "-grouping replaces the terminal bridge oxygen of the triphosphate chain has been synthesized by the reaction of imidodiphosphate with PI-adenosine P2-diphenyl pyrophosphate (Michelson, A. (1964), Biochim. Biophys. Acta 9/, 1). AMP-PNP is stable (<3z hydrolysis) for months at -20" as the tetrasodium salt and in...

A critical part of thin-film composite solar cells is conduction through the transparent electrode. Currently the material of choice for the window electrode is indium tin oxide (ITO). The natural abundance of indium however is insufficient for highvolume production of solar cells. Moreover, good quality ITO is made by expensive vapor-deposition processes. We propose to develop nanostructured d...

5-Fluorouracil (FUra) and 5-fluoro-2’ -deoxyuridine (FdUrd) are common chemotherapeutic drugs for the treatment of advanced colorectal cancer. Two recognized mechanisms of action of these agents are inhibition of thymidylate synthase (TS) and incorporation of fluorinated UTP into cellular RNA. In previous studies on drug scheduling of both fluoropyrimidines, we observed the highest therapeutic ...

Computational Fluid Dynamic (CFD) modeling of a continuous countercurrent hydrolysis process was performed using ANSYS-CFX. The liquid properties and flow behavior such as density, specific heats, dynamic viscosity, thermal conductivity, and thermal expansivity as well as water solubility of the hydrolysis components triglyceride, diglyceride, monoglyceride, free fatty acid, and glycerol were c...
