A catalyst free method of igniting an ionic liquid is provided. The method can include mixing a liquid hypergol with a HAN-based ionic liquid to ignite the HAN-based ionic liquid in the absence of a catalyst. The HAN-based ionic liquid and the liquid hypergol can be injected into a combustion chamber. The HAN-based ionic liquid and the liquid hypergol can impinge upon a stagnation plate positioned at top portion of the combustion chamber.

Fast ignition and sustained combustion of ionic liquids

Methods and systems of providing a source of hydrogen and oxygen with high volumetric energy density, as well as a power systems useful in non-air breathing engines such as those in, for example, submersible vehicles, is disclosed. A hydride reactor may be utilized in forming hydrogen from a metal hydride and a peroxide reactor may be utilized in forming oxygen from hydrogen peroxide. The high temperature hydrogen and oxygen may be converted to water using a solid oxide fuel cell, which serves as a power source. The power generation system may have an increased energy density in comparison to conventional batteries. Heat produced by exothermic reactions in the hydride reactor and the peroxide reactor may be transferred and utilized in other aspects of the power generation system. High temperature water produced during by the peroxide reactor may be used to fuel the hydride reactor.

The invention relates to high power, spark induced breakdown spectroscopy (SIBS) detectors with controllable delay time and to spark induced breakdown spectroscopy plasma generators with dual electrodes with specific electrode material, both for use in methods and apparatuses for detecting spectral signatures of atomic emissions, (e.g., from heavy metals such as lead, mercury, chromium, cadmium, arsenic, antimony and beryllium and radioactive materials such as uranium, plutonium, thorium and technetium) for measuring, for example, atomic concentrations of samples such as vapors and airborne particulates.
