  • Publication number: 20210163525
    Abstract: The disclosure discloses an ultrasonic-assisted pretreatment method for extraction of multiple steroid hormones in a sediment, including the following steps: (1) lyophilizing the sediment, grinding the sediment, and passing the ground sediment through a 40-60-mesh sieve; (2) placing the sample obtained in step (1) in a container; (3) adding an extractant to the container in step (2), shaking the mixture for 15 s-30 s, centrifuging the mixture to collect an supernatant after ultrasonication, and repeating extraction three times; where the extractants used in the three times of extraction are two of methanol, acetonitrile and acetone; and (4) after mixing the supernatants of the three times of extraction obtained in step (3), concentrating the mixture under a nitrogen flow at 20-30° C., passing the concentrated mixture through a filter, and performing detection. By using the method of the disclosure, the maximum recovery can be up to 100%.

  • Patent number: 8471087
    Abstract: Disclosed is a process for separating an acidic contaminant and light hydrocarbon of a light hydrocarbon feed having a large contaminating acidic contaminant content. Among other features, the process uses a combination of distillation and membrane separation arranged in a unique way to yield a high-purity light hydrocarbon product and a high-purity acidic contaminant product.

  • Publication number: 20120056753
    Abstract: A meter receives a new communication frame from a power line, and determines whether the new communication frame is used to read power consumption of the meter. If the new communication frame is used to read power consumption of the meter, the meter generates a response frame of the new communication frame, and broadcasts the response frame to the concentrator via the power line to report the power consumption of the meter. If the new communication frame is not used to read power consumption of the meter, the meter broadcasts the new communication frame to the at least one other meter and the concentrator via the power line.

  • Patent number: 7427552
    Abstract: A method for fabricating integrated circuit devices, e.g., Flash memory devices, embedded Flash memory devices. The method includes providing a semiconductor substrate, e.g., silicon, silicon on insulator, epitaxial silicon. In a specific embodiment, the semiconductor substrate has a peripheral region and a cell region. The method includes forming a first dielectric layer (e.g., silicon dioxide) having a first thickness overlying a cell region and a second dielectric layer (e.g., silicon dixode) having a second thickness overlying the peripheral region. In a specific embodiment, the cell region is for Flash memory devices and/or other like structures. The method forms a pad oxide layer overlying the first dielectric layer and forms a nitride layer overlying the pad oxide layer.
