This paper reviews some of the major and most recent advances in nanoscale-magnetic resonance imaging (nano-MRI) for personalized medicine (PM). Nano-MRI may drastically expand the capabilities of the traditional magnetic resonance images (MRI), down to the nanometer scale and possibly, in the near future, at the atomic scale. Nano-MRI is potentially able to observe structures which cannot be s...

in this work, we report on the synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, ctab as cationic surfactant and butanol as a cosurfactant. surface modification have been carried out by using poly(ethyleneglycol) (peg). the structure,morphology, and magnetic properties of the products were characteriz...

lithium disilicate nano-powders were synthesized via a mild condition hydrothermal reaction at 180 ºc for 48 and 72 h with a non stoichiometric1:2 li:si molar ratio in naoh aqueous solution using li2co3 and sio2.h2o as raw materials. the synthesized materials were characterized by powder x-ray diffraction (pxrd) technique and fourier transform infrared (ftir) spectroscopy. the xrd data showed t...

Recently the applications of functionalized magnetic nano particles are increased in a linear fashion. This is due to the ease of synthesis and controlled growth of magnetic nano particles. In the present investigation gentamicin drug functionalized Fe3O4 nanoparticles were synthesized by co-precipitation method. Thus obtained nano hybrid was characterized by Fourier transform infrared (FTIR) s...

In this work, a bench-scale process was developed using mineral-processing methods to recover iron from a placer deposit located in Bardaskan, Khorasan-e-Razavi, Iran. The mineralogical studies were performed by X-ray Diffraction (XRD), X-ray Fluorescence (XRF), Electron Probe Micro-Analyzer (EPMA), and an optical microscope. These studies indicated that titanomagnetite, magnetite, and hematite...

The metal sulfi des exhibit a great diversity of electrical and magnetic properties with both scientifi c interest and practical applications. These properties apply major constraints on models of the electronic structure (or chemical bonding) in sulfi des (Vaughan and Rosso 2006, this volume). The pure and doped synthetic equivalents of certain sulfi de minerals have actual or potential applic...

Background and Objectives : Ethylbenzene (EB) is a dangerously organic compound which the presence of this pollutant in water solutions can be considered as an environmental and public health hazard. In this study, nano magnetic particles (Fe 3 O 4 ) were used as an adsorbent to remove ethylbenzene from aqueous solutions. Methods : The specification of the adsorbent was investigated by transmis...

Methods for imaging of nanocomposites based on X-ray, electron, tunneling or force microscopy provide information about the shapes of nanoparticles; however, all of these methods fail on chemical recognition. Neither do they allow local identification of mineral type. We demonstrate that infrared near-field microscopy solves these requirements at 20 nm spatial resolution, highlighting, in its f...

Surface, interface and bulk properties of artificially structured, new magnetic materials play a fundamental role in modern science and technology. From thin films to patterned magnetic nano-structures, these magnetic materials and systems can be utilized in many electrical and electronic devices. Using highly surface sensitive techniques, electron capture spectroscopy (ECS), angleand energy-re...
