Abstract: Example specimen holders for X-ray diffractometer are disclosed. One example specimen holder includes an angle plate. The angle plate includes a first side and a second side. The first side and the second side are configured to join each other at an angle. The first side is configured to couple to a flange of an X-ray diffractometer, where the X-ray diffractometer includes a goniometer. The second side is configured to position a specimen in a measurement position for the X-ray diffractometer, where a rotation axis of the goniometer passes through a surface of the specimen.

Abstract: The present disclosure provides a method for trapping corrosion products in a plant, the method comprising: installing, at the plant where a fluid is being processed, a trap system having one or more magnetic elements, at least one entry port, and at least one exit port; configuring the trap system such that the fluid flows in a prescribed pattern through the trap system; and activating the one or more magnetic elements of the trap system such that the corrosion products in the fluid are retained by the one or more magnetic elements and limited to portions of the plant while the fluid flows from the at least one entry port to the at least one exit port.

Abstract: Systems and methods include a method for determining the purity of a sample. An image capture is performed of a reference material having a known purity and an unknown material having an unknown purity for which a priori information is known, including that the reference material and the unknown material have a same material type. An image comparison of the reference material and the unknown material is performed to determine a color difference vector between an image of the reference material and an image of the unknown material. A purity of the unknown material is determined using the color difference vector.

Abstract: The present invention regards a fin for a finned pack for heat exchangers, including a plate in which a plurality of through holes is formed for the positioning of tubes intended to convey a first heat exchange fluid, the plate having an edge as well as two main faces, each intended to be licked by a second heat exchange fluid in a crossing direction (A-A) from an inlet portion to an outlet portion of the edge of the plate.
