  • Patent number: 10519076
    Abstract: The present invention generally concerns isolated nanoparticles via the decomposition of a ternary metal hydride. More specifically, the present invention harnesses increased energy densities from two distinct nanoparticles isolated by a precise decomposition of LiAlH4. The singular material is air stable and is a nanocomposite of Li3AlH6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer, which we call nMx. The nanocomposite protects and preserves the high energy densities of the core metals isolated from the controlled reaction and makes the nanoparticles safe to handle in air. The final composite is devoid of byproducts or phase transitions that will decrease the energy output of the nanocomposite. The method of the present invention creates a narrow distribution of nanoparticles that have unique burning characteristics useful for many applications.

  • Patent number: 10501385
    Abstract: The present invention generally concerns decomposing a ternary metal hydride to isolate nanoparticles to use in a fuel grain. More specifically, the present invention harnesses increased energy densities from two distinct nanoparticles isolated by a precise decomposition of LiAlH4. The singular material is air stable and is a nanocomposite of Li3AlH6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer. We call this nanocomposite nMx, which protects and preserves the high energy densities of the core metals isolated from the controlled reaction, making the nanoparticles safe to handle in air. The narrow distribution of nanoparticles has no byproducts or phase transitions that decrease energy output. The unique burning characteristics of nMx enhance the combustion of solid propellant formulations compatible with solid or hybrid rocket motors, where fuel grains are cast, pressed, or 3D printed with nMx powder, a polymeric binder, or optional additives.

  • Publication number: 20180321220
    Abstract: A method for monitoring the metabolic state of an organism, cell, tissue, group of cells, organelles or organelle with or without a metabolic modulating agent or with or without a genetic alteration capable of modulating metabolism is disclosed. The biological material of interest is placed in a conductive solution in close proximity to a first electrode that is electrically coupled to a second electrode. A potential is applied to the electrodes sufficient enough to create a potential gradient between the two. If the biological material of interest is undergoing oxidation reactions, reduction reactions, or producing electrochemically active compounds as a result of metabolism, these will react at the first electrode, and in some cases, achieve direct electron transfer to the first electrode and generate a detectable electrical current. This current is directly proportional to the metabolic rate of the biological material of interest.
