摘要： In an example, an engine includes a thermal expansion unit comprising expansion material that expands in response to a temperature increase of the expansion material and contracts in response to a temperature decrease of the expansion material. The engine includes a structure comprising a heat receiving region, wherein at least a portion of the thermal expansion unit is disposed within the structure. The heat receiving region is configured to transfer thermal energy from a source of thermal energy to the expansion material through a first thermal energy transference path. The transfer of thermal energy to the thermal expansion unit causes expansion of the expansion material within the thermal expansion unit. The expansion of the expansion material causes an increase in length of the thermal expansion unit. The increase in length of the thermal expansion unit causes establishment of a second thermal energy transference path through which thermal energy is transferred from the expansion material to outside the thermal expansion unit.

摘要： A method for operating the liquid air energy storage (LAES) includes production of the storable liquid air through consumption of a low-demand power and recovery the liquid air for co-production of an on-demand power and a high-grade saleable cold thermal energy which may be used, say, for liquefaction of the delivered natural gas; in so doing zero carbon footprint is provided both for fueled augmentation of the LAES power output and for LNG co-production at the LAES facility.

摘要： An actuation device may include a plurality of actuation units disposed about an axis. Each actuation unit of the plurality of actuation units may include a shape memory alloy component, an auxetic material component operationally coupled to the shape memory alloy component, and a power source operationally coupled to the shape memory alloy component. Additionally, the actuation device may include a control system operationally coupled to the power source, the control system is configured to actuate the shape memory alloy component through the power source. Further, when actuated, the shape memory alloy component moves in a direction outward from the axis to pull the auxetic material component, and the auxetic material component expands in a direction perpendicular to the movement direction of the shape memory alloy component.

摘要： A system and methods for base excitation of moderately high vibration of micro-cantilevers are disclosed. A micro-cantilever may be coupled to one or more actuators adjacent its base. The actuators may comprise bulk materials, bridges, or formed wires that expand and contract by application of electric currents, due to, for example, the effect of electro-thermal heating or piezoelectric effects. Single actuators or an array of actuators may be placed around the micro-cantilever to oscillate it and apply actuation pulses. The system and methods, and adjustments of the geometrical parameters, may be performed to yield a nominal natural frequency in the system. The excitation of actuators with signals corresponding to the natural frequency may induce resonance in the system and may result in high amplitude vibrations and displacement of the cantilever tip of the micro-cantilever. Various architectures of the actuators may be implemented to stimulate different frequencies of the beam and induce displacement in different direction and amplitudes.
