  • Patent number: 8796634
    Abstract: A tube-style neutron detector, a panel-style neutron detector incorporating a plurality of tube-style neutron detectors, and a panel-style neutron detector including a plurality of anode wires are provided. A plurality of channels is provided in a neutron detector such that each channel has an inner surface of a coating layer including a neutron-absorbing material. A wire anode is provided at end of each channel so that electrons generated by a charged daughter particle generated by a neutron are collected to detect a neutron-matter interaction. Moderator units can be incorporated into a neutron detector to provide improved detection efficiencies and/or to determine neutron energy spectrum. Gas-based proportional response from the neutron detectors can be employed for special nuclear material (SNM) detection. This neutron detector can provide similar performance to 3He-based detectors without requiring 3He and without containing toxic, flammable, or high-pressure materials.

  • Patent number: 8194246
    Abstract: A system generates a photoacoustic spectrum in an open or closed environment with reduced noise. A source focuses a beam on a target substance disposed on a base. The base supports a cantilever that measures acoustic waves generated as light is absorbed by the target substance. By focusing a chopped/pulsed light beam on the target substance, a range of optical absorbance may be measured as the wavelength of light changes. An identifying spectrum of the target may detected by monitoring the vibration intensity variation of the cantilever as a function of illuminating wavelength or color.

  • Patent number: 7716965
    Abstract: An electrochemical suspended element-based sensor system includes a solution cell for holding an electrolyte comprising solution including at least one electrochemically reducible or oxidizable species. A working electrode (WE), reference electrode (RE) and a counter electrode (CE) are disposed in the solution.

  • Patent number: 7579052
    Abstract: Highly sensitive sensor platforms for the detection of specific reagents, such as chromate, gasoline and biological species, using microcantilevers and other microelectromechanical systems (MEMS) whose surfaces have been modified with photochemically attached organic monolayers, such as self-assembled monolayers (SAM), or gold-thiol surface linkage are taught. The microcantilever sensors use photochemical hydrosilylation to modify silicon surfaces and gold-thiol chemistry to modify metallic surfaces thereby enabling individual microcantilevers in multicantilever array chips to be modified separately. Terminal vinyl substituted hydrocarbons with a variety of molecular recognition sites can be attached to the surface of silicon via the photochemical hydrosilylation process.

  • Publication number: 20080206103
    Abstract: Methods for the preparation of a stable, self-assembled monolayer on the silicon surface or metallic coating of a microcantilever are disclosed. The methods produce a microcantilever suitable as a chemical sensor. In a microcantilever produced using one version of the method, a metallic coating is disposed on a side of the microcantilever, a bridging atom is bonded to the metallic coating, a first spacer group is bonded to the bridging atom, a second spacer group is bonded to the bridging atom, and a chemical recognition agent is bonded to the first spacer group. In another version of the method, a silicon surface of a microcantilever is hydrogen terminated, and a calixarene chemical recognition agent is carbon linked to the silicon surface using photochemical hydrosilylation. Among other things, the calixarene may be bonded to a crown ether for ion detection or bonded to a area for the recognition of explosives by hydrogen bonding to nitro groups.
