The magnetic structure of the iron monoarsenide FeAs is studied using rst-principlescalculations. We consider the collinear and non-collinear spin-spiral wave magnetic orderingand magnetic anisotropy. It is analitically shown that a magnetic triaxial anisotropy resultsin a sum of two spin-spiral waves with opposite directions of wave vectors and dierent spinamplitudes, so that the.

HPLC Basics High performance liquid chromatography or commonly known as HPLC is an analytical technique used to separate, identify or quantify each component in a mixture. The mixture is separated using the basic principle of column chromatography and then identified and quantified by spectroscopy. A computer analyzes the data show the output in display.

2009-1-29In this work a microfluidic separation system for magnetic beads was experimentally realized according to theoretical simulations. The manipulation of magnetic beads is achieved by magnetic gradient fields resulting from conduc-ting lines near the microfluidic channel. Experi-mental and calculation results are compared with each other.

Magnetic nanoparticles MNPs which exhibit magnetic and catalytic bifunctionalities have been widely accepted as one of the most promising nanoagents used in water purification processes. However, due to the magnetic dipole-dipole interaction, MNPs can easily lose their colloidal stability and tend to agglomerate. Thus, it is necessary to enhance their colloidal stability in order to maintain.
