abstract background: fisheries safety control and considering heavy metal accumulation is one of the most important factors in maintaining health society and assuring the safety of this valuable food. the purpose of this study is evaluating the potential of bioaccumulation and exposure to lead and cadmium due to consumption of penaeus semisulcatus in tehran city 2012.. methods: samples were col...

Due to the unique optical properties like high brightness and narrow emission bands of Quantum dots, it is used as simple fluorescence materials in bio-imaging, immunoassays, microarrays, and other applications. To easy invistigate cell lines that overexpressed somtostatin receptors, somatostatin (SST) was conjugated with Quantum dots carrying PEG amine (Qdots-PEG-NH2). The conjugation of SST t...

Zn-Al layered double hydroxide (LDH) nanoparticles with carbonate as the charge balancing anion in the interlayer space were synthesized using co-precipitation method. Then, the carbonate base Zn-Al LDH nanoparticles were doped with phosphate ion via anion-exchange reaction to synthesize Zn-Al-[PO43-]-[CO32-]. The structure and composition were characterized by X-ray diffraction (XRD), Fourier ...

Introduction: This study was carried out to determine elements (Li, Na, K, Mg, Ca, Ba, B, Al, Si, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Ag and P) in the Suaeda vermiculata (S. vermiculata) and Suaeda aegyptiaca (S. aegyptiaca) in three different regions of Southern Iran using inductively coupled plasma optical emission spectrometry (ICP-OES) after microwave-assisted acid digestion. Materials and ...

A magnetically recoverable catalyst consisting of Mn (III) salophen complex was prepared. The synthesized catalyst was characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometry (VSM), inductively coupled plasma atomic emission spectroscopy (ICP-AES) and Fourier transform infrared (FT-IR). The immobilized catalyst was shown to be an ef...
