A method for producing silicate-containing magnetic particles having a closed and tight silicate layer and high purity. In addition, the novel method prevents an uncontrolled formation of aggregates and clusters of silicates on the magnetite surface, thereby having a positive influence on the properties and biological applications. The method enables depletion of nanoparticulate solid substance particles on the basis of a fractionated centrifugation. The silicate-coated magnetic particles exhibit optimized magnetization and suspension behavior as well as advantageous run-off behavior from plastic surfaces. These highly pure magnetic particles coated with silicon dioxide are preferably used for isolating nucleic acids from cell and tissue samples, whereby the separating out from a sample matrix ensues by means of magnetic fields. The particles are particularly well suited for the automatic purification of nucleic acids, mostly from biological body samples for the purpose of analyzing them with different amplification methods.

In an embodiment, a method of fabricating a working component for magnetic heat exchange comprises arranging at least two articles comprising a magnetocalorically active phase and an elongated form with a long axis having a length 1 and a shortest axis having a length s, wherein 1≥1.5 s, such that the shortest axes of the at least two articles are substantially parallel to one another and securing the at least two articles in a position within the working component such that the shortest axes of the at least two articles are substantially parallel to one another within the working component.

The present invention relates to the formation of a stable dianionic π-dimer-[TCNE].sub.2.sup.2− (TCNE-tetracyanoethylene) at ambient conditions that exhibits unusually intense white emission over the entire visible spectral range (400-800 nm) and has application in designing white light emitting devices. Particularly, the present invention relates to a process for the preparation of stable dimer in an organic solvent upon aging at room temperature, in the presence of anions such as Br−, Cl−, SCN−, which reduces the TCNE to a TCNE anion radical (TCNE..sup.−) which subsequently dimerizes to form the stable dianionic dimer upon aging. More particularly, the dimer formed in this invention opens a new class of materials to design white light emitting devices having high intensity over the entire visible spectral range. The dimer also forms electron transfer salts used to develop new molecule-based metals, superconductors, and magnets.
