Superglass Dynamics Of Solid Helium
… acquisition and temperature control, and used a high-dynamic range DC-SQUID-based displacement sensor to detect its rotational susceptibility. We observed ultra-slow evolution towards equilibrium of the relaxation dynamics in the resonance frequency f ( T ) and dissipation D ( T ) of the …

Evaluation of Novel Fine Coal Dewatering Aids
The costs of cleaning fine coal are substantially higher than those of cleaning coarse coal. Therefore, many many coal companies in the U.S. choose to discard fine coal (150 micron x 0) by means of 6-inch diameter hydrocyclones. The cyclone overflows are stored in fine coal impoundments, which …

Processing of Low Rank Coal and Ultrafine Particle Processing by Hydrophobic-Hydrophilic Separation (HHS)
… hydrophilic. The slurry was subjected to a high-shear agitation to selectively agglomerate the chalcopyrite and to leave the siliceous gangue dispersed in aqueous phase. The agglomerates were then separated from dispersed gangue minerals by screening and the agglomerates dispersed in a …

Concentration and Recovery of Rare Earth Elements from Eastern US Coal Refuse
… and dispersive liberation steps. In these tests, high-shear agitation in the presence of a polyelectrolyte, followed by sedimentation was able to isolate the REE-enriched fine clay particles from siliceous gangue minerals. Following the dispersive liberation step, all samples were found to have an …

Hydrophobic-Hydrophilic Separation Process for the Recovery of Ultrafine Particles
… over the past five years due to the depletion of high-grade ore deposits. The situation for REEs is worse; there is no domestic supply chain of REEs in the U.S. since the demise of Molycorp, Inc. in 2016. Studies have shown that the rejected materials from copper and coal processing plants contain …

Protein stability: Impact of formulation excipients and manufacturing processes in protein-based pharmaceuticals
… and drying. In addition to these stresses, the agitation processes used during reconstitution may also destabilize the protein’s native structure. Two key processes used in preparation of protein based formulations were studied in this work; mechanical agitation and freeze drying. The aim of …
