  • Publication number: 20240382877
    Abstract: The present disclosure is directed to at least one embodiment of a filter that is configured to remove contaminants utilizing a first conductive mesh (e.g., first electrode) and a second conductive mesh (e.g., second electrode) that extends around the first conductive mesh. For example, the first conductive mesh may receive a first electrical signal and the second conductive mesh may receive a second electrical signal such that the first and second conductive meshes are oppositely charged from each other (e.g., the first conductive mesh is positively charged and the second conductive mesh is negatively charged). Anions that are present within the fluid or generated by an electrical field between the first and second conductive meshes may interact with the contaminants such that the contaminants are attracted to at least one of the first and second conductive meshes, respectively.

  • Publication number: 20240141537
    Abstract: The present disclosure provides a superhydrophobic and self-cleaning anticoagulant composite coating material and a preparation method and use thereof, and relates to the technical field of biomedical materials. In the coating material provided by the present disclosure, a titanium dioxide nanotube-based structure increases microscopic roughness of a surface of a titanium-based metal substrate, and a hydrophobic modification layer reduces surface energy of the material. The rough structure and the hydrophobic modification layer have a synergistic effect to construct a superhydrophobic surface, making the surface of the material have self-cleaning characteristics and low adhesion. Air can be retained on the surface of the material to form an air layer, thereby reducing the contact area between the material and bacteria and platelets in the blood, and inhibiting adhesion of the bacteria, platelets, and plasma proteins to the material.

  • Publication number: 20240027411
    Abstract: A method for determining the concentration of a compound in ultrapure water is provided. The method includes dividing the ultrapure water into a first part and a second part and decomposing the compound in the first part, so that the first part includes a characteristic substance. The method also includes measuring a first concentration of the characteristic substance in the first part and a second concentration of the characteristic substance in the second part and calculating the difference between the first concentration and the second concentration. The method further includes obtaining the concentration of the compound in the ultrapure water based on the difference.

  • Publication number: 20230408393
    Abstract: The present disclosure is directed to various methods and systems for monitoring real time efficiency of filters as well as testing the filters with tests that are similar to real world use of the filters to update technical specifications of the filters. The methods and systems monitoring the real time efficiency of the filters may utilize one or more particle counters to monitor their efficiency in real time. The data collected by the particle counters may be utilized to determine whether respective ones of the filters need to be replaced or regenerated by a backwash regeneration process. The updated technical specifications from the real world testing of the filters may be utilized in determining whether respective ones of the filters need to be replaced or regenerated. These real world testing and real time monitoring reduces the likelihood that workpieces are exposed to contaminant particles reducing scrap costs.
