introduction water is a vital component of animals and the main medium for biochemical reactions. basically, water characteristics have a close relation to its molecular structure and it can be affected by external processing such as magnetic field. some researches indicated that magnetized water resulted in better efficiency in agricultural products compared with the ordinary water. in animal ...

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...

Over the past few decades, glaciers worldwide have been retreating, resulting in changes in water resources with direct socio-environmental impacts. The flow of glaciers is intrinsically linked to the morphology and dynamics of sub-glacial water. However, these sub-glacial processes remain largely mysterious, and current techniques of modeling the glacial flow based on these sub-glacial structu...

A simple and rapid microextraction procedure based on the application of magnetic nanoparticles and hydrophobic 1-Hexylpyridinium hexafluorophosphate [Hpy][PF6] ionic liquid (IL) was applied to trace determination of gatifloxacin. A mixture of [Hpy][PF6] and magnetic nanoparticles was injected into the sample solution containing the analyse of interest and a cloudy solution was forme...

Water pollution by anthropogenic activities is proving to be of critical concern as the heavy metals affect aquatic organisms and can quickly disperse to large distances. This poses a risk to both human health and the aquatic biota. Hence, there is a need to treat the wastewater containing toxic metals before they are discharged into the water bodies. During recent years, magnetic nanoparticles...

We present a novel method to control water drop movement on superhydrophobic surfaces through magnetic fields. Water drops with paramagnetic particles can be moved on fractal Si-nanowire superhydrophobic surfaces at high speeds by displacing a magnet. A drop pinned to a surface defect can be combined with another drop containing paramagnetic particles thus allowing movement of the newly formed ...

Proton nuclear magnetic resonance (NMR) imaging previously has been used to examine structure and pathologies of the eye. The present study investigates the use of a saturation-transfer technique, which exploits water-macromolecular proton magnetic interactions, to enhance image contrast in the rabbit eye in vivo. Upon steady-state saturation of the macromolecular-proton magnetization, the wate...
