摘要： Compositions and mechanisms for the transfer of spin-triplet excitons from a singlet exciton fission material (e.g., tetracene) to an inorganic semiconductor (e.g., n-doped silicon) are provided. The compositions include one or more interlayers, including a charge transfer interlayer (e.g., zinc phthalocyanine), and, optionally, a passivation interlayer (e.g., hafnium oxide, HfO2). The triplet transfer mechanism proceeds via the formation of a charge transfer intermediate state. The transition to the intermediate state is energetically favored by strategically positioned HOMO and/or LUMO levels of the charge transfer interlayer between the singlet fission layer and the inorganic semiconductor. The intermediate state is formed through a transition of either the electron or the hole of the triplet exciton in the charge transfer interlayer (depending, at least in part, on the relative positions of the energy levels) to the conduction or valence band of the inorganic semiconductor, respectively. Methods of forming the compositions are also disclosed.

摘要： Systems and methods for extending the interior cargo bay of fixed-wing cargo aircraft into a replaceable tailcone bay are disclosed. The system includes an aircraft and a removable tailcone configured couple to the aft end of the fuselage. The aircraft fuselage includes a cargo bay and an aft end opening into the cargo bay. The tailcone, when attached, encloses the aft end opening the cargo bay. The tailcone can include an interior volume configured to extend the fuselage cargo bay such that the interior volume defines an aft end of a cargo bay of the cargo aircraft. In some examples, the tailcone includes a plurality of segments, which can be configured to extend from the aft end of the aircraft to adjust a length of the cargo extension provided by the tailcone.

摘要： During landing and rejected-takeoff flight phases, aircraft drag is a useful force to supplement braking and reduce stopping distance. During descents, aircraft drag is a useful force in steepening flight path angle and achieving higher rates of vertical descent speed at a trimmed forward flight speed in unaccelerated flight. A flight control system is detailed herein that deflects opposing flight control components in a symmetric fashion to increase aircraft drag, while maintaining controllability.

摘要： Methods of determining a final space reservation for a new aircraft are disclosed. The methods include using parametric definitions of potential payloads to generate a population of representative payloads for use in creating an initial space reservation. The methods include accounting for and applying a variety of margins on each potential payload and taking the union of potential payloads. Alternatively, the union can be taken first and then the margins applied. A homogenous space reservation can be determined based upon a variety of differently shaped or sized payloads, including a margin build-up to mitigate risk of unknowns associated with future changes in specific payload shapes and sizes, build tolerances, environmental conditions, and/or loading and unloading motions and clearances. Once this space reservation is known, it is possible to design an external shape of a carrying vehicle by staying outside of this space reservation.

摘要： Systems, devices, and methods for monitoring the health of a mechanical system that includes a rotating shaft as disclosed can measure various parameters of the rotating shaft to assess health and performance of the mechanical system. A measuring device can rotate with the rotating shaft and can allow for strain to be measured in tension, which can provide for accurate rotating shaft parameter measurements with low cost and simple installation. The measuring device can include a connector that can couple to the rotating shaft, a bridge that can couple to the connector, and a strain-measuring sensor associated with the bridge such that the strain sensor can measure deformation of a portion of the bridge that can deform with rotation of the rotating shaft. The measuring device can be designed to amplify the strain experienced by the rotating shaft which can reduce noise in the strain measurement.

摘要： Systems and methods for three-dimensionally printing different configurations of a printed fiber using a single nozzle are provided. The provided systems and methods harness deformation, instability, and fracture of viscoelastic materials to adjust dimensionless parameters related to a speed of extrusion and a height of a nozzle to create the different configurations. A controller of the system can operate to create these different configurations using the single nozzle without having to change out hardware during the process. Instead, the dimensionless parameters can be adjusted while the printing is occurring to achieve the different configurations. The disclosure provides various systems for carrying out the printing, and methods of using the same.
