Abstract: This disclosure relates to a process for selectively extracting Fe(III) ions from an aqueous feedstock containing Fe(III) ions and non-ferric ions. The process comprises contacting the feedstock with an organic phase comprising a phosphonium salt or ammonium salt ionic liquid under liquid-liquid extraction conditions for a time sufficient to allow transfer of at least some of the Fe(III) ions from the feedstock to the organic phase to provide an Fe(III) ion laden organic phase and an Fe(III) depleted feed-stock, and separating the Fe(III) ion laden organic phase from the Fe(III) depleted feedstock.

Abstract: A rapid autofocus method for a stereo microscope includes steps of: calculating a disparity of each of stereo microscopic images in a stereo microscopic calibration image sequence; extracting a clear stereo microscopic image sequence from the stereo microscopic calibration image sequence; then, finding out a largest disparity and a smallest disparity among the disparities of all the stereo microscopic images in the clear stereo microscopic image sequence; at a chosen magnification, arbitrarily acquiring a stereo microscopic image; finally, determining a disparity range according to the disparity of the acquired stereo microscopic image, the largest disparity and the smallest disparity, and realizing an autofocus of a target object in the acquired stereo microscopic images. The disparity range is obtained via once off-line calibration at the same magnification, and applicable to the autofocus at an arbitrary timing.

Abstract: An X-ray image detection device includes a scintillator, a data integration processing unit and a plurality of X-ray image sensors. The X-ray image sensors are arranged in a matrix form and located on the back of the scintillator and connected to the data integration processing unit. Each X-ray image sensor includes a plurality of pixels, and each pixel has a dual driving pixel structure and includes two thin film transistors and two thin film photodiodes. The source electrodes of the thin film transistors are connected to the cathodes of the thin film photodiodes respectively, and the gate electrodes are connected to an odd row driving line and an even row driving line respectively, and the drain electrodes are connected to a common signal output line. Both anodes of the two thin film photodiodes are connected to a common ground wire of the pixels.
