Abstract: The spontaneous assembly of chiral structures from building blocks that lack chirality is fundamentally important for colloidal chemistry and has implications for the formation of advanced optical materials. Here, we find that purified achiral gold tetrahedron-shaped nanoparticles assemble into two-dimensional superlattices that exhibit planar chirality under a balance of repulsive electrostatic and attractive van der Waals and depletion forces. A model accounting for these interactions shows that the growth of planar structures is kinetically preferred over similar three-dimensional products, explaining their selective formation.

The introducer assembly includes a sheath and a hub assembly interconnected with the proximal end of the sheath, the hub assembly including a body defining an interior passageway in fluid communication with the lumen of the sheath, the body having a proximal end and a distal end. A valve assembly is positioned within the interior passageway of the body, the valve assembly having a valve member, the valve member being at least partially movable from a first position to a second position with respect to the valve collar. A vacuum chamber positioned distal to the valve assembly and in fluid communication with the interior passageway of the body and the lumen of the sheath, the vacuum chamber including a vacuum port.

Abstract: A post-partum hemorrhage monitoring system has a fluid collection funnel having a opening configured to receive post-partum hemorrhaging, an open distal end, a base, an interior configured to receive postpartum hemorrhage, a lip extending exteriorly from the open proximal end, an anterior surface configured to be placed adjacent an anterior vaginal wall of a patient, a posterior surface configured to be placed adjacent a posterior vaginal wall of a patient and a stem having a lumen extending from an open distal end of the funnel. The anterior surface tapers from the lip to and through the base, the posterior surface has substantially no taper from the lip to and through the base to provide a flattened flow path, and the stem is offset from the geometric center of the fluid collection funnel.

Abstract: Absorbent articles having curved elasticized laminates and apparatuses and methods for forming such articles are disclosed. In one embodiment a method of forming an article may comprise moving absorbent assemblies and elasticized laminates in the machine direction. The method may further comprise oscillating the elasticized laminates in the cross-machine direction to impart a curvature, bonding the elasticized laminates to the absorbent assemblies while maintaining the imparted curvature such that at least a portion of the elasticized laminates are disposed outboard of longitudinal side edges of the absorbent assemblies, and finally separating the absorbent assemblies into individual absorbent articles, where the elasticized laminates extend in a curving manner throughout the absorbent articles.

Abstract: Absorbent articles of the present disclosure may be constructed with a secondary liner sheet placed on top of a body facing liner of the articles configured to form a pocket. The pocket provides a barrier, thereby separating a front region of the absorbent articles from a rear region. In this manner, the absorbent articles of the present disclosure may reduce the spread of bodily exudates throughout the articles. The reduced spreading of exudates may help to keep skin healthy by reducing the amount of skin exposed to the skin irritants within the exudates and/or by preventing additional skin irritants from being created by preventing the mixing of BM and urine, at least in proximity to the skin of the wearer.

Abstract: A method includes coupling a radiator panel assembly to a component, and conducting heat from the component via a thermally conductive hinge into at least one base radiator panel in the radiator panel assembly. The method further includes placing the at least one base radiator panel in a position to radiate a fraction of the heat into space through a surface of the at least one base radiator panel, and dynamically varying the position of the at least one base radiator panel to vary an amount of heat loss through the at least one base radiator panel to regulate a temperature of the component.

Abstract: Absorbent articles having curved elasticized laminates and apparatuses and methods for forming such articles are disclosed. In one embodiment, an absorbent article having a front waist region, a crotch region, and a rear waist region may comprise a chassis comprising bodyside liner, an outer cover, an absorbent body. The article may further comprise a pair of elasticized laminates attached to the chassis to form elasticized leg cuffs. Each of the first pair of elasticized laminates may comprise a laminate material forming a fold and an elastomeric member disposed between the laminate material. Each of the first pair of elasticized laminates may be attached to the chassis such that the fold comprises an outermost longitudinal edge of the article throughout the crotch region, and the fold and the elastomeric member of each of the elasticized laminates may extend in a curving manner throughout the crotch region.

Abstract: An aerial camera system including a plurality of main reels, a camera interface/safety reel and a stabilized camera head. The camera head is supported from main cables from the main reels with a safety reel cable providing power, data and video communication between the camera head and a main computer system. Each of the main reels, the camera interface/safety reel and the camera head are in communication with the main computer system, which controls the feeding and reeling in of the main cables. Further, the computer system controls the feeding and reeling in of the safety reel cable, which typically only follows the camera head as it moves in three-dimensional space, but may in emergency mode support the weight of the camera head and be used to slowly pull the camera head up and out of the way so that it does not interfere with any activity below the flight area.

Abstract: Disclosed are nanostructures having nanoprisms and agents, such as diagnostic and/or therapeutic agents. Nanoprisms with a surface plasmon resonance in the near-infrared convert irradiation, such as from a laser into heat selectively to allow the dissociation, such as dehybridization of oligonucleotide duplexes, of agents associated with the nanoprism surface. These nanostructures show morphological, chemical, and functional stability under hours of irradiation. Further disclosed are methods of selectively releasing agents from nanostructures after directed surface plasmon resonance mediated heating of the nanoprisms. Released agents, such as oligonucleotides, are unharmed by this process and can be repeatedly released and sequestered under spatiotemporal control.
