摘要: The method comprises feeding a second fluid in a porous sample; measuring a resistivity or/and conductivity in a plurality of regions having different second fluid contents in the porous sample; and repeating the following steps. Determining an estimated local volume of first fluid contained in each region from the resistivity or/and conductivity measured in the region and from an estimated value of the representative parameter; calculating an estimated total volume of first fluid in the porous sample from each estimated local volume of first fluid contained in each region; and modifying the value of the estimated representative parameter to minimize the difference between the estimated total volume and a measured total volume of fluid produced from the porous sample, the representative parameter of the porous sample being the estimated representative parameter minimizing said difference.

摘要: A replaceable alcohol sensor module for use with a breathalyzer. The alcohol sensor module requiring calibration can be removed from the body of the breathalyzer and replaced with a new alcohol sensor module. The alcohol sensor module has at least an alcohol sensor and a circuitry mounted on a PCB that removable connects the replaceable alcohol sensor module to the breathalyzer. The circuitry transmits the signal and/or electrical current generated by the alcohol sensor to a processing unit of the breathalyzer for processing.

摘要: This disclosure is a low power plasma system monitor method, which can be used to monitor the uniformity of the low power plasma system. A deposition process is performed on a testing substrate to form a metal film on the testing substrate. The resistance of the metal film on the testing substrate is measured to generate a plurality of first sheet resistance values. A testing pretreatment process is performed on the testing substrate through the low power plasma system to form a testing passivation on the metal film of the testing substrate. The resistance of the testing substrate after the testing pretreatment process is measured to generate a plurality of second sheet resistance values. Then the first sheet resistance values and the second sheet resistance values are analyzed to know the uniformity of the low power plasma system.

摘要: A structure includes an insulating layer on a semiconductor substrate, and a first through-hole and a second through-hole formed in the insulating layer. The second through-hole is formed in the insulating layer at a set distance from the first through-hole. The structure also includes a first electrode portion and a second electrode portion. The first electrode portion is formed by filling the first through-hole. The first electrode portion includes a probing pad on the insulating layer. The probing pad is wider than an opening area of the first through-hole. The second electrode portion is formed by filling the second through-hole. The second electrode portion includes a probing pad on the insulating layer. The probing pad is wider than an opening area of the second through-hole.

摘要: Fabricating a nanopore sensor includes depositing a first and second oxide layers on first and second sides of a sapphire substrate. The second oxide layer is patterned to form an etch mask having a mask opening in the second oxide layer. A crystalline orientation dependent wet anisotropic etch is performed on the second side of the sapphire substrate using the etch mask to form a cavity having sloped side walls through the sapphire substrate to yield an exposed portion of the first oxide layer, each of the sloped side walls being a crystalline facet aligned with a respective crystalline plane of the sapphire substrate. A silicon nitride layer is deposited on the first oxide layer. The exposed portion of the first oxide layer in the cavity is removed, thereby defining a silicon nitride membrane in the cavity. An opening is formed through the silicon nitride membrane.

摘要: A method of detecting a stimulus can include detecting an output from a radio frequency identification tag including a sensor. A smartphone-based sensing strategy can use chemiresponsive nanomaterials integrated into the circuitry of commercial Near Field Communication tags to achieve non-line-of-sight, portable, and inexpensive detection and discrimination of gas phase chemicals (e.g., ammonia, hydrogen peroxide, cyclohexanone, and water) at part-per-thousand and part-per-million concentrations.

摘要: A gas detection device (100) and a process monitor an area for a combustible target gas. A gas sample (G) enters into a measuring chamber (9). A semiconductor sensor (1) including an electrically conductive sensor component (10) has an electrical detection variable that changes with decreasing concentration of the combustible target gas. An oxidation component (2) oxidizes combustible target gas in the measuring chamber. The detection variable is measured at a detection time, and the oxidation component is in a switched-on state or is switched on. The oxidation component oxidizes at least a part of the combustible target gas in the measuring chamber up to a reference time. The detection variable is measured again at the reference time. The difference between the measured value at the reference time and the measured value at the detection time is an indicator for the concentration of combustible target gas.
