A method for non-contact analyte detection by selectively exciting one or more analytes of interest using an IR source optionally operated to produce pulses of light and tuned to at least one specific absorption band without significantly decomposing organic analytes and determining if the analyte is present by comparing emitted photons with an IR detector signal collected one or more times before, during, or after, exciting the analyte. Another embodiment of the present invention provides a method for non-contact analyte detection by selectively exciting analytes of interest using one or more IR sources that are optionally operated to produce pulses of light and tuned to at least one specific wavelength without significantly decomposing organic analytes, wherein the analyte is excited sufficiently to increase the amount of analyte in the gas phase, and wherein the content of the gas is examined to detect the presence of the analyte.

Analyte detection with infrared light

The present invention is directed to a method for non-contact or stand off chemical detection by selectively exciting one or more analytes of interest using an IR source tuned to at least one specific absorption band without significantly decomposing the analyte and determining if the analyte is present by comparing emitted photons with an IR detector signal made before and during or shortly after exciting the analyte. Another embodiment provides a method for non-contact or stand off chemical detection by selectively exciting one or more analytes of interest using an IR source tuned to at least one specific absorption band without significantly decomposing the analyte, wherein the analyte is excited sufficiently to generate a vapor plume, and wherein the plume is examined to detect the presence of the analyte. Additionally, the present invention provides for a system for non-contact or stand off chemical detection.

Detection of chemicals with infrared light

A method for fabricating a transducer suitable for a fluidic drive for a miniature acoustic-fluidic pump or mixer that includes an acoustic transducer attached to an exterior or interior of a fluidic circuit or reservoir. The transducer converts radio frequency electrical energy into an ultrasonic acoustic wave in a fluid that in turn generates directed fluid motion through the effect of acoustic streaming. The method includes depositing a piezo-electric thin-film onto a platinum coated silicon wafer or substrate with capping electrodes, defining each separate transducer; and dicing said piezoelectric tin-film to provide individual transducers.

This invention pertains to transfer of a solid target material onto a substrate by vaporizing the material by irradiating it with intense light of a resonant vibrational mode of the material and depositing the vaporized material on a substrate in a solid form.

Deposition of thin films using an infrared laser

The invention relates to the deposition of transparent conducting thin films, such as transparent conducting oxides (TCO) such as tin doped indium oxide (ITO) and aluminum doped zinc oxide (AZO) on flexible substrates by pulsed laser deposition. The coated substrates are used to construct low cost, lightweight, flexible displays based on organic light emitting diodes (OLEDs).

Pulsed laser deposition of transparent conducting thin films on flexible substrates

The fluidic drive for miniature acoustic-fluidic pump and mixer is comprised of an acoustic transducer attached to an exterior or interior of a fluidic circuit or reservoir. The transducer converts radio frequency electrical energy into an ultrasonic acoustic wave in a fluid that in turn generates directed fluid motion through the effect of acoustic streaming. Acoustic streaming results due to the absorption of the acoustic energy in the fluid itself. This absorption results in a radiation pressure and acoustic streaming in the direction of propagation of the acoustic propagation or what is termed &ldquo;quartz wind&rdquo;.

A multicomponent film on a substrate can be annealed at higher temperatures in oxygen by using a specifically designed annealing vessel. The vessel is formed of a multicomponent material which has at least all of the components of the first multicomponent material of the film or, in the case where there are nonvolatile components, then the vessel is formed of a second multicomponent material which has at least the same composition of relatively volatile components as the first multicomponent film. As the multicomponent film is annealed for a sufficient time within the vessel the multicomponent film remains in contact with a vapor of the first multicomponent material and the vessel material. This process called bomb annealing prevents loss of volatile components from the film and roughening of the film surface and leads to films with lower dielectric loss. Preferred thin film materials are ferroelectric materials although any material could be used. The annealing can be done in oxygen at temperatures higher than 900&deg; C.

This invention pertains to a device of a substrate and a ZrO,-based semiconductor disposed thereon and a method for depositing the semiconductor on the substrate. The semiconductor is typically in the form of a film of 1-20 weight % ZrO,and 99-80 weight % In,O,or SnO,. The semiconductor is tunable in terms of optical transmission and electrical conductivity. Its transmission is in excess of about 80% over the wavelength range of 400-900 nm and its resistivity is from about 1.3&times;10,&OHgr;-cm to about 6.5&times;10,&OHgr;-cm. The deposition method is characterized by depositing in a chamber the semiconductor on a substrate by means of a physical vapor deposition whole maintaining a small oxygen pressure in the chamber.

Fluidic drive for miniature acoustic fluidic pumps and mixers

The order parameter of a superconductor is reduced by injecting spin-polarized carriers into the superconductor. The reduction in the order parameter is used to modulate the critical current of the superconductor. In a typical embodiment, a current is caused to flow through a superconductor. Spin polarized electrons are then injected into the path of the current in the superconductor by biasing a magnetic metal with respect to a terminal of the superconductor. The bias current may be varied to modulate the injection and thus the flow of current through the superconductor.
