Abstract: The present disclosure provides systems and methods for producing a hydrogen storage vessel that is lightweight. The hydrogen storage vessel may comprise an inner body and an outer body structured as concentric rings with a conic interface. The vessel may have four material layers, including a barrier layer, an insulation layer, a fiber knit, and an abrasion layer. The fiber knit may be braided to trap the hydrogen, as the barrier layer may not be completely impermeable. Additionally, the fiber braid may be clamped to the outer body, enabling pressure pushing on the inner body to wedge and seal the storage vessel.

Abstract: A method is provided for biosynthetic production of cannabinoids in microorganisms from a carbon source precursor. This method describes the genetic modifications needed to engineer microorganisms to produce cannabinoids as well as a method for identifying and quantifying cannabinoids from fermentation broth. A system is also provided for tuning the method to produce different cannabinoids of interest by systematically modulating the enzymes encoded by the genetic modifications introduced in the microorganism.

Abstract: A method of imaging an organism includes introducing a composite nanoparticle into a circulating fluid of an organism to form a circulating fluid mixture in the organism is provided. The composite nanoparticle comprises a core comprising at least one of a contrast agent and a magnetic material, and at least one layer of biocompatible material surrounding the core. The method further includes receiving an image of at least a portion of the organism where the circulating fluid has circulated, removing at least a portion of the circulating fluid mixture from the organism at a first rate, applying a magnetic field to the removed portion of the circulating fluid mixture to selectively remove the composite nanoparticle from the circulating fluid mixture and to produce a filtered fluid mixture, and returning the filtered fluid mixture to the circulating fluid of the organism at a second rate.

Abstract: A continuously variable transmission may have a first set of rollers and a second set of rollers that act upon skewed driving and driven surfaces of discs. The input to output ratio of the continuously variable transmission may be changed by pushing either one of the first and second sets of rollers closer to a rotating shaft. To maintain symmetrical loading within the continuously variable transmission, an idler disc assembly may have a strain compensator that deflects to compensate for deflection of outer discs due to elasticity of the main shaft.

Abstract: A spar of a rotor blade having moderate depth transitions to a relatively much deeper shank over a relatively short distance. This rapid transition enables a low-weight blade root that is structurally efficient, offers a high moment capability, and enables high Mach number axial flow. A transition could advantageously reduce section depth by at least 15%, 20%, 30%, or even 40% over at most 5%, 6%, 10%, or 12% of a total length of the rotor blade. Such a transition could advantageously be accomplished using a cuff, which has interfaces with each of the spar and the shank. The rotor blade shank has a generally circular cross-section which allows for a rotary attachment to a hub, where the attachment may advantageously comprise a mechanical or elastomeric bearing. Preferred embodiments have a spar with a generally rectangular cross-section.
