The red sand which is known as Teri sand in Tamil Nadu consists of 5.5% Total Heavy Minerals (THM) out of which 3.7% is ilmenite. The other minerals, zircon, sillimanite and garnet are in the order of abundance identified. On processing this feed to recover ilmenite by using spirals followed by dry high intensity magnetic separator and high tension separator, the ilmenite concentrate obtained c...

Abstract Background Ilmenite and rutile are naturally occurring titanium-bearing heavy minerals. Sri Lanka consists of ilmenite in placer deposits mainly along the northeast coast. The commercial value is higher than ilmenite. Therefore, current study focuses to upgrade Lankan ores using commercially available activated carbon as a reducing agent. fraction was initially separated from raw beach...

The first complete magnetic recorder (wire on a drum) was constructed in 1898 by Poulsen (Denmark). In 1938 the first recorders using plastic tape with an iron oxide layer were used. Since then, magnetic sound recording has become the most popular way of storing broadcast programmes for transmission at any time. Early attempts with temporary disc recording and photographic recording proved unsu...

In recent years magnetic nanoparticles (MNPs) are widely used in different scientific field. In magnetic resonance imaging (MRI), MNPs increase the contrast and quality of the images. In addition, magnetic nanoparticles, as separator, can break up some pathogenesis from human body. On the other hand, under DC magnetic field, MNPs can carry and release drug into the target tissue. In this approa...

We report the utilization of microfluidic technology to phage selection and demonstrate that accurate control of washing stringency in our microfluidic magnetic separator (MMS) directly impacts the diversity of isolated peptide sequences. Reproducible generation of magnetic and fluidic forces allows controlled washing conditions that enable rapid convergence of selected peptide sequences. These...

A new ultrahigh-resolution photoemission electron microscope called PEEM3 is being developed at the advanced light source (ALS). An electron mirror combined with a sophisticated magnetic beam separator is used to provide simultaneous correction of spherical and chromatic aberrations. Installed on an elliptically polarized undulator beamline, PEEM3 will be operated with very high spatial resolut...
