Abstract: Apparatus and associated methods relate to measuring temperature of a fluid within a hydraulic vessel using a temperature probe that has an annular recess circumscribing a projecting sensor tip. The annular recess is configured to permit fluid flow into an aperture region of a vessel wall through which the temperature probe contacts the fluid within the hydraulic vessel. Because the temperature probe projects from the annular recess within the aperture, a net projection dimension, as measured in a projection direction from an interior surface of the vessel wall proximate the aperture to a sensor, is less than a gross projection dimension, as measured in the projection direction from a bottom of the annular recess to the sensor tip. In some embodiments, this configuration advantageously improves a ratio of thermal conductivity between the fluid and the temperature probe and thermal conductivity between the temperature probe and a sensor housing.

Abstract: Apparatus and associated methods relate to generating a temperature measurement signal based upon a weighted average of signals generated by a resistive temperature detector (RTD) and a thermocouple device. The thermocouple device includes first and second thermocouple junctions. The first thermocouple junction is thermally coupled to the RTD, and the second thermocouple junction is thermally isolated from the RTD. The thermocouple is configured to generate a signal indicative of a difference between first and second thermocouple junctions, which is substantially equal to the difference between the RTD and the second thermocouple junction due to the thermal coupling configuration. The RTD generates a signal indicative of a temperature of the RTD. A weighted sum of the first and second signals is indicative of a temperature of the second thermocouple junction, which responds rapidly to temperature fluctuations, due to its having a relatively small thermal mass compared with the RTD.

Abstract: A method for fabricating nanostructured polymeric materials based on a combination of inkjet printing and template synthesis. Layer-by-layer assembled nanotubes can be synthesized in a polycarbonate track-etched (PCTE) membrane by printing poly(allylamine hydrochloride) (PAH) and poly(styrenesulfonate) (PSS) sequentially. By changing the printing conditions, polymeric nanotubes or nanowires can be prepared by printing poly(vinyl alcohol) (PVA) in a PCTE template. Inkjet printing paired with template synthesis can be used to generate patterns comprised of chemically distinct nanomaterials. Thin polymeric films of layer-by-layer assembled PAH and PSS can be printed on a PCTE membrane. Inkjet printing paired with template synthesis can also be used to prepare functional mosaic membranes, such as charge mosaic membranes comprising polyelectrolytes of different charges to pattern positively charged or negatively-charged domains, respectively, on the surface of the template.
