Abstract: A dual phase high entropy boride-carbide composite for extreme environments, comprising dual phases of high entropy boride (HEB) and high entropy carbide (HEC), wherein the high entropy boride comprises (Zr—Hf—Ti—V)B2 and wherein the high entropy carbide comprises (Zr—Hf—Ti—V)C. A method of making a dual phase high entropy boride-carbide composite for extreme environments, comprising the steps of utilizing a pressureless reactive sintering process, providing a Zr—Hf—Ti—V—B4C powder blend, maintaining a low sintering temperature, allowing the Zr—Hf—Ti—V—B4C powder blend to result in HE-Alloy powder and B4C, allowing the B4C to result in 4B and C and heat, reacting the HE-Alloy powder with the B and the C, and forming a HE-boride composite and a HE-carbide composite, wherein the HE-boride composite and HE-carbide composite comprise (Zr—Hf—Ti—V)B2+(Zr—Hf—Ti—V)C.

Abstract: 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.

Abstract: A pressure locking clamp includes a base, a hook arm, and a clasp arm. An imaginary central plane divides the base into a first and second half. The hook arm pivots on the first half of the base around a first axis parallel to the imaginary central plane. The clasp arm pivots on the second half of the base around a second axis parallel to the imaginary central plane. The hook and clasp arms each includes a lock contact area. In a closed state of the pressure locking clamp, the hook and clasp arms and the base together form an eye enclosure. In the closed state, pressure inside the eye enclosure presses the lock contact area of the clasp arm against the lock contact area of the hook arm, and this inhibits the hook and clasp arms from pivoting away from each other, reinforcing the eye enclosure.

Abstract: 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.

Abstract: The embodiments are directed to protecting objects having sensitive electronics from electromagnetic energy radiation. An object with the sensitive electronics has a film applied to the object's outer surface. The film conforms to the object's outer surface contours. The film has a substrate foundation, an array in intimate adjacent contact with the substrate foundation. The array has a plurality of radio frequency (RF) witness films overlain on the substrate foundation. Each RF witness film in the plurality of RF witness films is equally-spaced from adjacent RF witness films.
