A new Schiff base 2-aminothiophenol furfural self assembled monolayer (SAM) has been fabricated on a bare gold electrode as a novel sensor for determination of dopamine. Electrochemical impedance spectroscopywas utilized to investigate the properties of the Au 2-aminothiophenol furfural self assembled monolayermodified electrode (Au ATF SAM-ME) using the [Fe(CN)6]3-/4- redox couple. The electro...
Detailed studies are done in order to investigate the ore body in Sangan mine. Analyses results showed very low amount of gold in mineralized zone, (max 32 ppb). It is indicated that there is a positive relation between Au, S and As whereas there was no special relation between Au and Cu. Therefore Au can not be found along with Cu sulfides such as chalcopyrite. The LREE elements are higher tha...
We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr e...
le xvii siècle en france a véritablement été celui dun changement dans la production dramatique: il a vu lexplosion des productions variées et complémentaires nées des progrès de la technique et des transformations de toute une société en pleine mutation. aussi loin que remontent ses origines, la comédie nest pas à proprement parler un genre littéraire. il faut attendre le siècle dor du théâtr...
نانو ذرات، به خصوص نانو ذرات فلزی، خواص شگرفی از خود نشان می دهند که با خواصشان در حالت حجمی متفاوت هستند. این خواص به علت ساختار و سطح نانو مقیاس آنها ظاهر می شوند. یکی از روش های ساخت نانو ذرات فلزی ، حل کردن نمک فلزات در حلال های مختلف و سپس احیای آنها توسط عوامل احیاگر است. در این تحقیق نانو ذرات طلا از طریق احیای اسید کلروآئورات (haucl4) توسط تری سدیم سیترات ساخته شدند. همچنین به منظور جمع...
the conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. a novel nano-au/poly (4-aminobenzoicacid) (paba) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. the paba film and nano-au/paba film were characterized by scanning...

BACKGROUND Skull-stripping is the procedure of removing non-brain tissue from anatomical MRI data. This procedure can be useful for calculating brain volume and for improving the quality of other image processing steps. Developing new skull-stripping algorithms and evaluating their performance requires gold standard data from a variety of different scanners and acquisition methods. We complemen...
In a Relativistic Diffusion Model (RDM), the evolution of netproton rapidity spectra with √ sNN in heavy systems is proposed as an indicator for local equilibration and longitudinal expansion. The broad midrapidity valley recently discovered at RHIC in central Au + Au collisions at √ sNN= 200 GeV suggests rapid local equilibration which is most likely due to deconfinement, and fast longitudinal...
The reaction of [Ru(L)2(H2biim)](ClO4)2 [L1 = 2,2¢-bipyridine (bpy) or L2 = 2-(phenylazo)pyridine (pap) and H2biim = 2,2¢-biimidazole] with Au(tht)Cl (tht = tetrahydrothiophene) in presence of base in methanol produced a terametallic cationic complex [{Ru(L)2(biim)}<s...
