    摘要： A technique is provided for controlling biomolecules in a nanodevice. A membrane has two reservoirs at opposing ends of the membrane. A nanochannel is formed in the membrane connecting the two reservoirs. A gate electrode is formed on the membrane such that the gate electrode extends laterally in a region of the nanochannel. A biomolecule is trapped in the nanochannel by applying a first voltage to the gate electrode. In response to trapping the biomolecule, the biomolecule is stretched in the nanochannel by applying a second voltage to the gate electrode. The biomolecule is stretched based on changing from the first voltage to the second voltage applied to the gate electrode.

    摘要： The ionophore and polymer membrane selective for aluminum (III) ion provide an ionophore that is selective for aluminum (III) ion [Al3+]. The ionophore is diethyl (2-azobenzoic acid) malonate, which has the structure: The ionophore may be used as a dopant in a polymer membrane formed from a polymer matrix, e.g., poly (vinyl chloride) (PVC), and that may also include a plasticizer, such as dioctylphthalate (DOP) and o-nitrophenylloctyl ether (o-NPOE). The polymer membrane may be incorporated into an ion selective electrode (ISE) that can be used as a potentiometric sensor for the detection of Al3+ ions in wastewater.

    摘要： A gas sensor having first and second electrodes, an ion conducting solid electrolyte membrane positioned therebetween, first and second electrically conductive gas diffusion layers, first and second electrode contact members for electrically coupling said first and second electrodes to an external circuit, a water reservoir, a gas entry passageway and a water permeation barrier for controlling the transport of water vapor to the ion conducting solid electrolyte membrane. The water permeation barrier is a thin walled member which allows water vapor to diffuse therethrough and evaporate from an exit surface, the thickness of the water permeation barrier controlling the internal relative humidity of the sensor. A method for adjusting the present sensor in-situ due to changes in the current humidity conditions of the sensor so as to keep the gas sensitivity loss within a predetermined range is also disclosed.
