Abstract: A device and method that creates linear motion or acceleration of fine particles and molecules are described. The device includes a plurality of ring electrodes arranged along an axis so that a cylindrical harmonic field is formed when electrical voltage is applied separately to each ring of the plurality of rings cylindrical harmonic field. A method of driving gaseous molecules and nanoparticles in linear motion by operating a device that includes a plurality of ring electrodes arranged along an axis. The method includes providing gaseous molecules or nanoparticles in a high vacuum environment, applying an electrical voltage to each ring of the plurality of rings to form a cylindrical harmonic field that includes a drift axis, and aligning and accelerating the gaseous molecules or nanoparticles along the drift axis for storage, pumping out, or separation of the gaseous molecules or nanoparticles.

Abstract: A tiny and portable micro-spectrometer deployable in a bullet-like form that is inexpensive to the point that it can even be disposable is described. The device is based on the micro-spectrometer that uses the Fresnel diffraction principle that allows a tiny implementation with a nanometer resolving power of spectral signal. A bullet-like micro-spectrometer has an integration of a super capacitor as a power source, a charging coil for the super capacitor, an LED or laser diode light source and driver, an analog to digital converter (ADC) circuit, and a telemetry system with antenna string. An LED or laser diode runs in a burst mode to generate deep or vacuum UV to excite target material. When the excited state of target material undergoes a singlet or triplet transition, this transition process yields fluorescence or luminescence which is a material-dependent. The micro-spectrometer senses and uses this spectral emission from material to identify the spectral signature of the targeted material.

Abstract: A photo-catalyst (Ep) is regarded as an alternate method to replace the plasma chemical process and as an additional catalytic processing scheme on top of a micro- or nano-structured catalyst (Ec) and electro-catalyst (Ev). The potential energy reduction that results from the effect of photo-enhanced electro-catalyst (PEEC) is significant.
