in this study, we synthesized herceptin conjugated magnetic nanoparticles (hmns) as an alternative probe to discover the levels of her2 (human epidermal growth factor receptor-2) in the surface of cells. these nanoparticles can be used by magnetic resonance imaging (mri) (non-invasive methods) for screening the patients with her2 positive or negative tumors. dextran coated iron oxide nanopartic...

results the maximum si was obtained at the highest applied flip angle (45°). the linear relationship between si and nanoparticle concentration was seen up to 112.21 and 98.83 μmol fe/l for the short (10°) and the long (45°) flip angles, respectively (r2 = 0.95). these values were reduced up to 48.54 and 42.73 μmol fe/l for these flip angles with r2 of 0.99. conclusions the maximum si will be in...

background: increased impervious surfaces in urban areas not only increase runoff volume and peak flow, but also worsen urban storm water pollution. the polluted runoff has many adverse impacts on human life and environment. the purpose of this study was to investigate and compare the efficiency of sand columns coated with nanoparticles of iron oxide in the presence and absence of a magnetic fi...

Recent work has indicated that iron (oxyhydr-)oxides are capable of structurally incorporating and releasing metals and nutrients as a result of Fe2+-induced iron oxide recrystallization. In the present paper, we briefly review the current literature examining the mechanisms by which iron oxides recrystallize and summarize how recrystallization affects metal incorporation and release. We also p...

Iron (III) oxide (Fe2O3) is an excellent material for absorbing visible light from the solar spectrum because of its suitable band gap. However, due to low mobility and high bulk carrier recombination, the photoconversion efficiency of iron (III) oxide has been proven to be very poor. Fabrication of nanostructured iron oxide can potentially compensate for the material’s poor properties. In this...

Graham Jones, J., and Warner, C. G. (1972). Brit. J. industr. Med., 29, 169-177. Chronic exposure to iron oxide, chromium oxide, and nickel oxide fumes of metal dressers in a steelworks. Occupational and medical histories, smoking habits, respiratory symptoms, chest radiographs, and ventilatory capacities were studied in 14 steelworkers employed as deseamers of steel ingots for periods of up to...

Introduction The current interest in iron/iron oxide nanoparticles for remediation applications can be partly attributed to their presumed ease of injection and faster reactivity. However, several processes can limit their effectiveness for degrading contaminants in groundwater include aging, aggregation and deposition. Under environmental conditions, nanoparticles with Fe(0) cores persist beca...

The main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (SOM) and lowavailability of macro and micro-nutrients. The effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (USWCS) on the chemical properties of a saline-sodic soil was investigated. The experimentwas conducted using a randomized complete block des...

Concretions cemented by iron oxide are abundant and diverse in the Jurassic Navajo Sandstone of southern Utah. Some of these structures are considered terrestrial analogs for concretions imaged on Mars. The Navajo concretions can be spheroidal, pipelike, or tabular with multicompartmented boxworks. These iron oxide concretions typically display a rinded structure: dense sandstone rinds cemented...
