Magnetic storage, specifically in hard drives has advanced significantly since the first disk drive built in 1956 [1]. Interestingly enough, most of the changes thus far have been realized by scaling the components of a disk drive [1]. In recent years, the superparamagnetic limit has been seen as a possible limit to the rapid increase in hard drive capacities. Antiferromagnetically coupled (AFC...

(Nuclear) Magnetic Resonance ((N)MR) is a non-invasive technique that has been used to acquire spatially resolved images of living organisms. Another application of clinical MR is MR Spectroscopy (MRS) in which chemical information can be extracted from a well-defined region (e.g. a voxel) in for example the human brain [de Graaf, 1998]. Brain tumors [Nelson, 1999], multiple sclerosis, epilepsy...

This reaserch aims at functionalizing magnetic mesoporous silica with methacrylic acid-3-aminopropyltriethoxysilane (Fe3O4@MCM-41@MAA-APTES) applied for removal of methylene blue from aqueous solution. Several variables (such as pH, dye concentration, adsorbent amount and contact time) have been investigated. Under optimum conditions, maximum capacity of 87.71 mg g-1 of MB was obtained for the ...

gravity and magnetic data are usually processed and interpreted separately, and fully integrated results basically are created in the mind of the interpreter. data interpretation in such a manner requires an interpreter experienced both on topics concerning potential field theory and the geology of the study area. to simplify the joint interpretation of data, the automatic production of auxilia...

iron oxide nanoparticles were synthesized by coprecipitation method using ammonia as precipitation agent. most researchers usually add ammonia into the iron salt solution but in this work the salt solution drop wise has been added to the ammonia and the new obtained results were compared with those of other researches. magnetic properties of nanoparticles were measured by vsm. the effect of rea...

In the present study, new multi-components spinel ferrite Zinc doped metallic ferrites are investigated. The synthesized compounds consisting of Zinc copper ferrite nanostructures were developed using the Co-precipitation technique. Powder X-ray diffraction pattern (XRD) confirms the formation of the spinel phase for all the samples. The lattice constant was studied through powder X-ray diffrac...
