Neodymium (Nd) was continuously extracted from aqueous solutions by trioctylphosphine oxide (TOPO) dissolved in the ionic liquid 1-Butyl-3-methylimidazolium Bis (trifluoromethanesulfonyl)imide [C4mim][Tf2N] small channel contactors. Kinetic studies confirmed a 1:6 Nd:TOPO extraction mechanism at high initial Nd concentrations of 0.005 and 0.01 M 0.001 nitric acid phase. The continuous flow extr...

BACKGROUND To quantitatively compare in-vitro and in vivo membrane transport studies of targeted delivery, one needs characterization of the magnetically-induced mobility of superparamagnetic iron oxide nanoparticles (SPION). Flux densities, gradients, and nanoparticle properties were measured in order to quantify the magnetic force on the SPION in both an artificial cochlear round window membr...

Hard magnetic films have a broad application area ranging from magnetic recording media to microelectromagnetic devices. A challenge for recording media is the 60% annual increase in areal density, which requires ever smaller magnetic dots. However, for a given magnetic anisotropy the reduction of dot size is limited, since below a critical magnetic volume the magnetisation becomes thermally un...

Neodymium-iron-boron (NdFeB) has become the most prominent permanent magnet alloy, with a wide variety of applications and an ever-increasing demand. Their recycling is important for securing supply critical raw materials used in their manufacturing. The use organic acids such as acetic acid been recent interest waste NdFeB magnets. Despite achieving good leaching efficiencies, published litera...

A high-quality strong-field hybrid undulator has been designed for an infrared FEL project to be performed at UCLA. The primary magnetic flux is provided by C-shaped vanadium-permendur yokes and SmCo5 magnets . An additional magnetic flux is supplied by thin NdFeB magnet blocks placed between the yoke poles . This magnet geometry provides a high saturation limit for the magnetic field in the ga...

To evaluate a number of ideas, which, in principal, can be implemented in the ERL insertion devices design, we built and tested 30cm long pure permanent magnet (PPM) undulator model. The model had 25.4mm undulator period, 5mm fixed gap and ∼ 1.07T maximum peak field on the beam axes. For the field strength control was utilized the phase adjustment scheme in which magnetic arrays are moved longi...

This paper presents design and analysis of torque and flux density in perpendicular magnetic gear with different magnetic materials, dimensions and air gap. The results were compared to each other. This type of gear offers both high gear ratio and high torque. Moreover the low speed side is connected to prime mover and high speed side is connected to load after analysis, which is sui table for ...

This communication describes a density-based method that uses magnetic levitation for monitoring solid-supported reactions and for distinguishing differences in chemical composition of polymers. The method is simple, rapid, and inexpensive and is similar to thin-layer chromatography (TLC; for solution-phase chemistry) in its potential for monitoring reactions in solid-phase chemistry. The techn...
