Telescoping boom systems, devices, and methods are provided in accordance with various embodiments. For example, some embodiments include zero dead band telescoping boom systems, devices, and methods. Embodiments in general include hard stop preloading mechanisms for telescoping booms with multiple tube segments. Some embodiments provide components that facilitate the deployment sequencing of the multiple tube segments along with facilitating preloading of the multiple tube segments of a telescoping boom. The tools and techniques provided may be integrated into the multiple tube segments rather than being provided as a separate system. Some embodiments allow for precise deployment of the multiple tube segments of the telescoping boom systems, devices, and methods.

Furlable sail devices, systems, and methods are provided in accordance with various embodiments. For example, some embodiments include a system and/or device that may include: a furlable boom; a furlable sail coupled with a distal end of the furlable boom; and/or a shear take-up mechanism coupled with a root end of the furlable sail. In some embodiments, the shear take-up mechanism applies tension to the furlable sail. The shear-take up mechanism may include one or more springs coupled with the root end of the furlable sail. In some embodiments, the furlable sheet includes a structural sheet. The structural sheet may include one or more areas with bending stiffness. The structural sheet may be fabricated to be self-supporting. In some embodiments, the furlable boom includes a slit-tube boom. Some embodiments may be configured as deorbit sails.

Methods, systems, and devices for furlable antenna blade components are provided in accordance with various embodiments. For example, some embodiments include a device that may include one or more furlable antenna blade components; each of the one or more furlable antenna blade components may include one or more conductive elements. In some embodiments, each of the one or more furlable antenna blade components include one or more laminate layers. Some embodiments include a method that may include: furling one or more furlable antenna blade components around a central axis; and/or securing the one or more furlable antennae blade components when in a furled state.

Nanophononic metamaterials and methods for reducing thermal conductivity in at least partially crystalline base material are provided, such as for thermoelectric energy conversion. In one implementation, a method for reducing thermal conductivity through an at least partially crystalline base material is provided. In another implementation, a nanophononic metamaterial structure is provided. The nanophononic metamaterial structure in this implementation includes: an at least partially crystalline base material configured to allow a plurality of phonons to move to provide thermal conduction through the base material; and at least one nanoscale locally resonant oscillator coupled to the at least partially crystalline base material. The at least one nanoscale locally resonant oscillator is configured to generate at least one vibration mode to interact with the plurality of phonons moving within the base material and slowing group velocities of at least a portion of the interacting phonons and reduce thermal conductivity through the base material.
