An allotrope-specific reagent includes a hydride molecule in complex with a specified elemental allotrope. The elemental allotrope included in the complex substantially retains a specified allotropic structure of the bulk element. For example, the reagent can contain a specified allotrope of carbon, such as amorphous carbon, diamond, or graphite. The allotrope-specific reagent can be useful for the synthesis of allotropic nanoparticles. A method for synthesizing the allotrope-specific reagent includes a step of ball-milling a mixture that includes a bulk hydride molecule, such as lithium borohydride powder, and a powder of a specified elemental allotrope.

A method of controlling molten metal flow and an electromagnetic brake system for a metal-making process, including: a first magnetic core arrangement having a first and second long sides with N.sub.c teeth, and arranged to be mounted to opposite longitudinal sides of an upper portion of a mould, a first set of coils, each being wound around a respective tooth of the first magnetic core arrangement, and N.sub.p power converters, with N.sub.p being an integer that is at least two and N.sub.c is an integer that is at least four and evenly divisible with N.sub.p, wherein each power converter is configured to feed a DC current to its respective group of 2N.sub.c/N.sub.p series-connected coils.

An electromagnetic actuating device includes a pole tube that is substantially cylindrical overall, an armature situated radially inside the pole tube, and an electromagnetic coil situated radially outside the pole tube, the pole tube having a first axial end and a second axial end. The pole tube is configured as a sleeve that is stamped and is brought into its shape by reshaping, the sleeve having, close to its first axial end, openings that extend in the circumferential direction.

A dry-type transformer core has an iron core with a number of limbs designed to be wrapped with a winding and interconnected by a number of magnetic yokes. The object is to produce a transformer of this type in a simple manner, which is especially well protected against corrosion. For that purpose, the dry-type transformer core includes a casing that is formed onto the iron core. The casing surrounds the iron core in a substantially flush manner.

Soft magnetic core, in which permeabilities that occur at least two different locations of the core are different.

Soft magnetic core, in which permeabilities that occur at least two different locations of the core are different.

Providing a high-density two-terminal memory architecture(s) having performance benefits of two-terminal memory and relatively low fabrication cost, is described herein. By way of example, the two-terminal memory architecture(s) can be constructed on a substrate, in various embodiments, and comprise two-terminal memory cells formed within conductive layer recess structures of the memory architecture. In one embodiment, a conductive layer recess can be created as a horizontal etch in conjunction with a vertical via etch. In another embodiment, the conductive layer recess can be patterned for respective conductive layers of the two-terminal memory architecture.

A dry-type transformer for mobile applications includes a transformer core, at least one radially inner first winding segment, and at least one radially outer, second hollow cylindrical winding segment. The segments are wound around a common winding axis and the transformer core passes therethrough. The segments are nested inside one another and radially spaced apart from one another, such that a hollow cylindrical cooling duct is formed therebetween. Spacing is achieved by spacer elements arranged such that the cooling duct allows a passage of coolant in an axial direction. The spacer elements are formed and arranged along the radial circumference of the cooling duct over the axial length thereof such that the proportionate weight of the horizontal transformer can be borne on at least one contact surface of the at least second winding segment without causing deformation to the cooling duct.
