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

A method of forming a metalized polymeric bubble in a space, microgravity environment is described. A liquid polymer bubble having a predetermined diameter is formed from a mixture comprising a liquid polymer and at least one of a UV curing material, a stabilizer, a UV absorber, or a surfactant. The liquid polymer bubble is cured with radiation to form a rigid polymer bubble. The rigid polymer bubble is then metalized with a metal to form the metalized polymeric bubble.

A laser device includes an optical resonator, a microwave driven discharge device, and a source for a second gas. The microwave driven discharge device is disposed relative to the optical resonator. The microwave driven discharge device operates at a discharge power and gas flow rate to produce a selected amount of energetic singlet oxygen metastables flowing in the direction of the optical resonator. The second source for the second gas is disposed between the optical resonator and the microwave driven discharge device. The second gas reacts with the selected amount of energetic singlet oxygen metastables to form an excited species in an amount sufficient to support lasing of the excited species in the optical resonator.
