Nanoporous materials have been widely used in many fields. However, their synthesis with uniform particle shapes, pore sizes, volumes, and surface areas remains a considerable challenge. Thus, choosing suitable controllable method for synthesizing nanoporous is crucial to obtain appropriate properties. Herein, titania particles (NPTPs) were prepared via the hydrothermal method. This study inves...

AIM Autism is a developmental disability characterized by severe deficits in social interaction and communication. The definite cause of autism is still unknown. The aim of this study is to find out the relation between exposure to Lead and/or mercury as heavy metals and autistic symptoms, dealing with the heavy metals with chelating agents can improve the autististic symptoms. METHOD Blood a...

Rechargeable aqueous Zn-ion battery has been considered as a key complement to the existing technologies due its intrinsic merits such operational safety and cost saving. However, issues of dendrite growth accompanied water consumption hinder further development. In this work, we utilize chelating agent, 2-Bis(2-hydroxyethyl) amino-2-(hydroxymethyl)-1,3-propanediol (BIS-TRIS), regulate solvatio...

Mercury occurs in various chemical forms, and it is different to health effects according to chemical forms. In consideration of the point, the evaluation of the mercury exposure to human distinguished from occupational and environmental exposure. With strict to manage occupational exposure in factory, it is declined mercury intoxication cases by metallic and inorganic mercury inhalation to occ...

Ion pair dispersive liquid- liquid microextraction (IP-DLLME) method combined with flame atomic absorption spectrometry was proposed for the determination of trace amounts of copper(II). By using pyrocatechol violet as chelating agent and cetyltrimethyl ammonium bromide as an ion pairing agent, the trace amount of copper(II) was extracted in chloroform. The factors influencing the formation cop...

The aim of this work was to develop a new and simple coacervative extraction method for the preconcentration and spectrophotometric determination of Cu(II) in water samples. Dithizone was used as the chelating agent while an anionic surfactant, namely sodium dodecyl sulfate (SDS), was used as extracting agent at room temperature. Central composite design (CCD) based on response surface methodol...

somatostatin analoges labeled with different radionuclides are able used for imaging and treatment of somatostatin receptor positive tumors. in this study tyr³-octreotide protected at lysine as an analoge of somatostatin was conjugated with bifunctional chelating agent 6-boc-hydrazinopyridine-3-carboxylic acid (boc-hynic) and after deprotecting of conjugate, purification was performed with prep...
