摘要： Described herein are ultra-thin nanocellulose flexible electronic device on which SU-8, an epoxy material which can become highly stressed upon UV exposure, is printed on desired areas. Upon UV exposure and then release from the surface it is anchored on, the nanocellulose device will spontaneously self-mold into a desired form due to stress differences between the SU-8 and the nanocellulose sheet. The flexible electronics can be manufactured using standard printed circuit board processing techniques, including electroless metallization and soldering of surface mount components.

摘要： A method of thermally protecting a leading edge of a hypersonic system includes saturating an annular primary wick in contact with an evaporator and having a first pore size with a phase change material by means of an annularly-inward secondary wick having a second pore size and being coupled to a liquid line, the second pore size being larger than the first, where a first end of the secondary wick extends into a reservoir and a second end of the secondary wick extends into the evaporator, the second end of the secondary wick having a terminal end. The method includes terminating the liquid line inside of the evaporator, transferring thermal energy from the leading edge into the phase change material, raising the temperature of the phase change material to a phase-change temperature, changing phase of the phase change material, and carrying away heat from the leading edge.

摘要： A benthic microbial fuel cell device (BMFC), namely an anode in contact with organic matter on the seafloor and a cathode in contact with overlying seawater, creates a closed path through which electric current can flow. In a conventional such device, it is used solely as a power source. However the application of a reverse voltage (for example, via solar power) results in storage of energy associated with the BMFC.

摘要： A method of measuring millisecond-scale blast and impact characterization in soft materials includes embedding one or more sensors in soft material, wherein the one or more sensors have mechanical properties approximately matching the soft material; applying a constant current to the one or more sensors; subjecting the soft material to a shock or impact event; measuring a response as a change in voltage; and converting the measured voltage to strain or pressure.

摘要： Methods and systems for determining extracellular concentration data of an analyte are disclosed. A method for determining extracellular concentration data of an analyte includes receiving sensor data from one or more arrays of functionalized plasmonic nanostructures on a localized surface plasmon resonance imaging chip in contact with a fluid containing at least one living cell for a plurality of times, determining intensity data for the one or more arrays, determining fractional occupancy based on the intensity data, and determining extracellular concentration data based on the fractional occupancy data. A system for determining extracellular concentration data of an analyte includes a LSPRi chip, a sensor component, an intensity component, a fractional occupancy component, a concentration component, and a processor to implement the components.
