Abstract: A chemical-electromagnetic hybrid propeller with variable specific impulse. Fuel gas ejected out from a spraying tube of the chemical propeller through chemical propulsion enters an ionization chamber through a first magnetic mirror tube for ionization. The fuel gas after ionization is heated up by radio-frequency ion cyclotron waves in an ion cyclotron wave heating chamber so as to improve the kinetic energy. Then a second magnetic mirror tube is used, so that ions in the fuel gas after the ionization are heated up many times in a reciprocating manner between the magnetic mirror tubes, and ejected to generate forward propulsion force. By means of the propeller, the propulsion force and the specific impulse are greatly increased.

Abstract: The present invention relates to an antimicrobial filter adopting optical fibers and to an air cleaner comprising the same. More particularly, the present invention relates to an antimicrobial filter using optical fibers and to an air cleaner comprising the same, in which ultraviolet rays, visible light or natural light is emitted directly through the surface of optical fibers contained in a filtering material, thus effectively killing, in a short time, microorganisms collected in the filtering material, such as bacteria, fungi, or viruses, which are harmful to the human body. Furthermore, a photocatalyst may be coated on the surface of the filtering material to achieve an improved sterilization effect. Thus, the deterioration of the sterilization effect caused by dust particles being continuously collected at the surface of filter fiber, which are disadvantages of existing antimicrobial filters, can be overcome.

Abstract: Actuation systems and methods for varying the angle of small turbine engine inlet guide vanes (IGV) and/or compressor stator vanes (CSV). Such systems and methods may employ a piezoelectric inchworm actuator (or a piezo stack actuator or magnetostrictive actuator, depending upon actuation requirements) to actively modify the angle of attack of a single or a cascade of inlet guide vanes or compressor stator vanes. The change in angle of attack is necessary due to large variations in engine operating envelope including but not limited to air density, velocity, temperature, and the like. The present invention is especially suitable to actuate small inlet guide vanes and compressor stator vanes found in small turbine jet engines including but not limited to those under ten (10) inches in diameter.

Abstract: The present invention relates to the formation and processing of nanostructures including nanotubes. Some embodiments provide processes for nanostructure growth using relatively mild conditions (e.g., low temperatures).

Such methods can both reduce the costs associated with nanostructure formation, as well as reduce the harmful effects of nanostructure fabrication on environmental and public health and safety.
