Harvesting fresh water and marine algae by magnetic separation: screening of separation parameters and high gradient magnetic filtration.
In this study, the focus is on magnetic separation of fresh water algae Chlamydomonas reinhardtii and Chlorella vulgaris as well as marine algae Phaeodactylum tricornutum and Nannochloropsis salina by means of silica-coated magnetic particles. Due to their small size and low biomass concentrations, harvesting algae by conventional methods is often inefficient and cost-consuming. Magnetic separa...
متن کاملThe magnetic response of paramagnetic Fe at high energy transfers
2014 Previous measurements in paramagnetic iron using polarized neutrons with polarization analysis revealed strong forward magnetic scattering. By contrast, the scattering at large wavevectors, was observed to be very weak. We report on additional measurements near the zone boundary, which extend to energy transfers of about 2 Tc (~ 200 meV). A value of 1.7 03BC2B is obtained, and the resultin...
متن کاملMagnetic study of some nanoferrite materials
The Mössbauer spectra of nanoferrite materials such as Ni0.25Mn0.75Fe2O4, Co0.5Mn0.5Fe2O4 and Ni0.4Co0.6Fe2O4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and Polyvinyl alcohol(PVA) as...
متن کاملMagnetic Separation of Giardia Cysts from Water
Background: Giardia is one of the infectious agents that can be transmitted by surface water and cause a disease. We designed and fabricated a magnetic system to separate the giardia cysts from water. Materials and Methods: In this study, giardia cysts were concentrated by sucrose floatation method. The cysts were mixed with physiological saline and their concentration was adjusted to 100,000 c...
متن کاملConfinement of paramagnetic ions under magnetic field influence: Lorentz- versus concentration gradient force based explanations
Concentration variations observed at circular electrodes with their axis parallel to a magnetic and normal to the gravitational field have previously been attributed elsewhere to the concentration gradient force only. The present paper aims to show that Lorentz force driven convection is a more likely explanation. preprint, finally published in Electrochemistry Communications 9 (2007), 2479–248...
