Abstract: Heat exchanger assemblies are provided that can include: a heat exchanger housing; at least one primary conduit operably coupled to the heat exchanger housing and configured to convey a primary heat exchange fluid; at least one secondary conduit operably coupled to the heat exchanger housing and configured to convey a secondary heat exchange fluid; at least one thermal interface between the primary and secondary fluids; and at least one sensor operably engaged with the thermal interface. Heat exchanger assemblies including molten salt, liquid metal, or water/steam as part of the heat exchange fluids of the heat exchanger assembly are provided. The heat exchanger assemblies can include: at least one thermal interface between primary and secondary heat exchange fluids of the heat exchanger assembly; and a sensor operably engaged with the at least one interface. The sensor must be installed in conjunction with the heat exchanger fabrication process as an embedded sensor.

Abstract: Biological material fouling assessment systems and methods are described. According to one aspect, a biological material fouling assessment system includes processing circuitry configured to access image data of an image of a surface of a substrate which has been fouled with biological material, wherein the image data comprises intensity information regarding a plurality of pixels of the image, and wherein the processing circuitry is further configured to process the intensity information regarding the pixels of the image to generate information which is indicative of an amount of the fouling of the biological material upon the surface of the substrate.
