摘要： Chemical functionalization of solid-state nanopores and nanopore arrays and applications thereof. Nanopores are extremely sensitive single-molecule sensors. Recently, electron beams have been used to fabricate synthetic nanopores in thin solid-state membranes with sub-nanometer resolution. A new class of chemically modified nanopore sensors are provided with two approaches for monolayer coating of nanopores by: (1) self-assembly from solution, in which nanopores −10 nm diameter can be reproducibly ceased, and (2) self-assembly under voltage driven electrolyte flow, in which 5 nm nanopore may be coated. Applications of chemically modified nanopore are provided including, the detection of biopolymers such as DNA and RNA, immobilizing enzymes or other proteins for detection or for generating chemical gradients; and localized pH sensing.

摘要： A process fluid temperature calculation system includes a first temperature sensor disposed to measure an external temperature of a process fluid conduit. The process fluid temperature calculation system has a stem portion having a known thermal impedance. A second temperature sensor is spaced from the first temperature sensor by the stem portion. Measurement circuitry is coupled to the first and second temperature sensors. A microprocessor is coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to provide an estimate of temperature of process fluid within the process fluid conduit using a heat flux calculation.

摘要： A first bridge fixed resistor (211) of a combustible gas detection apparatus (1) is composed of a resistor element which is less likely to deteriorate as compared with a second bridge fixed resistor (212) and a variable resistor section (213). The combustible gas detection apparatus (1) can judge a deteriorated state of at least one of the second bridge fixed resistor (212) and the variable resistor section (213) on the basis of the absolute value of a difference temperature ΔT which is the difference between a detection-time judgment temperature T1 and a reference judgment temperature T0. The combustible gas detection apparatus (1) obtains a corrected high-temperature-time voltage VH′ and a corrected low-temperature-time voltage VL′ through use of a voltage error ΔV1. Thus, a decrease in the accuracy in detecting the hydrogen concentration can be suppressed even when the resistance of the resistor section changes.
