Abstract: Methods and systems are provided for cyclical enrichment, especially of rare earth elements and isotopes. A tube, or ampule, optionally with one crucible, or with two coaxially opposite crucibles in fluid communication, is used to hold a source material in vacuum and irradiate the source material to enrich it with product material. Following the irradiation of the source substance (e.g., Yb, enriched with 176Yb) to yield the product substance (e.g., 177Lu), the mixture may be sublimated to remove most of the source substance and concentrate the product material, e.g., by heating the lower part and cooling the upper part of the tube, to condense sublimated source material at the top of the tube. Consecutively, the concentrated product substance may be purified, while the solidified source structure may be reused in irradiation/sublimation cycles to further enrich and concentrate the product material.

Abstract: A novel technology to create 3D-printed objects that are extremely temperature resistant, mechanically robust, ultra-low-wear, and exhibit self-healing behavior. The material can be manufactured in a wide variety of process conditions and even used as a high-strength adhesive, enabling hybrid fabrication strategies. The gel precursor for this material is formed from two solids that react to create a high-performance polymer when heated. Unlike similar materials, these are solid at room temperature and form a printable gel when dissolved in a solvent. Addition of a secondary solvent to this gel modifies the solubility and creates a super-saturated fluid with tunable rheology. Once the gel material has been printed, it is allowed to dry via forced convection. This removes the solvent and leaves only the uncured polymer precursors. After the majority of the solvent has been removed, the material is heated to its cure temperature, at which point it melts, cures, and re-hardens.

Abstract: Discharge heads with bent supporting legs for vertical pumps are described. A discharge head, according to examples, with bent supporting legs for vertical pump systems allows substantially reduced footprint (i.e., bottom plate size) and weight of discharge head without compromising torsional rigidity and structural integrity. The bent supporting legs coupling the mounting interface and the bottom plate and further connected through orthogonal stabilizers create a monocoque type frame. The reduction in the size of the bottom plate and (and thereby, the weight) allows utilization of valuable space in rig applications for other systems while preserving structural resonance, torsional rigidity performances.

The channel further an overarching wing on both sides of the channel under which an inner mounting plate of the mounting assembly can be constrained in the channel in at least an outward second direction. The mounting assembly further includes an outer mounting plate that overlaps the overarching wings on both sides of the channel. The wings are thus slidably engaged with the mounting assembly but restrained in a wing opening between the inner and outer mounting plates. A large force that would otherwise bend the wing outwardly is countered by a resulting force from the overarching outer mounting plate of the mounting assembly to keep the portable device coupled with the mounting system.
