The invention relates to a method for sensing target molecules in an analyte solution, a sensor for sensing target molecules in an analyte solution and a measurement system for sensing target molecules in an analyte solution. The method comprises providing a capture surface, wherein a plurality of capture molecules are arranged on the capture surface, each of the capture molecules being configured to bind to at least one of said target molecules. The method further comprises exposing the capture surface to the analyte solution to allow target molecules to bind to the capture molecules arranged on the capture surface. The capture surface is then exposed to a solution containing detection molecules, wherein each of the detection molecules contains an electrochemically active nanoparticle and is configured to bind to one of said target molecules bound to a capture molecule, thereby allowing said electrochemically active nanoparticles to bind to the capture surface through formation of a bond between the respective detection molecule comprising said nanoparticle and one of said target molecules bound to one of said capture molecules arranged on the capture surface. The method further comprises releasing nanoparticles that are bound to the capture surface and, after releasing said nanoparticles from the capture surface, determining an electrical signal at a detection electrode caused by electrochemical reactions of said nanoparticles released from the capture surface.

Embodiments relate to a system for predicting thermodynamic phase of a material. The system includes a phase diagram image scanning processing module configured to scan a binary phase diagram for each material to be used as a component of a high-entropy alloy (HEA). The system includes a feature computation processing module configured to generate a primary feature and an adaptive feature. The primary feature is representative of a probability that the HEA will exhibit a solid solution phase and/or an intermetallic phase. The adaptive feature is representative of a factor favoring formation of a desired intermetallic HEA phase. The system includes a prediction module configured to encode the primary feature and/or the adaptive feature with thermodynamic data associated with formation of HEA alloy phases to provide an output representation of the HEA alloy phases for a material under analysis.

An immersion probe with a variable connection length is configured to compensate for longitudinal and/or radial length variations in an immersion sublance connected to the immersion probe. The immersion probe is characterized by an adjustable portion that changes length upon engagement with a coupling end of an immersion sublance. The immersion probe can have a sensor head. An immersion assembly of the immersion probe connected to an immersion sublance can be used to take measurements or samples of molten metal in a converter furnace.

A fixture has a body that connects to a motor, the body having a bore. The body has a piston in the bore, separating the bore into a pressure chamber and a lubricant chamber in fluid communication with lubricant in the motor. A technician applies pressure to the pressure chamber, which causes the piston to increase pressure of the lubricant in the lubricant chamber and in the motor. The technician monitors a distance of movement of the piston, indicating a presence of residual air in the lubricant. If the movement meets a amount, the technician applies a vacuum to the lubricant chamber and bleeds out residual air from the lubricant in the motor.
