摘要： This invention relates to producing aluminum by electrolysis of a melt and can be used in the process control of an electrolyte composition by quantitative X-ray phase analysis (XRD) of potassium-containing electrolyte with calcium or calcium and magnesium additives. A quantitative XRD method is employed for analyzing doped samples of crystallized bath samples taken from baths. A weighted ground bath sample is mixed with a weighted quantity of sodium fluoride at a ratio, for example, 1:2 by weight. The weighted quantities are mixed and placed in a furnace (650-750° C. for 20-40 minutes) to dissolve sodium fluoride in the sample and recrystallize the sample with the desired phase composition. The doped sample is placed in a furnace (420-450° C) and held for 15-30 minutes. The doped sample is removed from the furnace and allowed to air cool. The phase composition of the doped sample is analyzed by any quantitative X-ray phase method.

摘要： A method, an apparatus and a system are provided for determining if a piece of luggage contains a liquid product comprised of a container holding a body of liquid. The piece of luggage is scanned with an X-ray scanner to generate X-ray image data conveying an image of the piece of luggage and contents thereof. The X-ray image data is processed with a computer to detect a liquid product signature in the X-ray image data and determine if a liquid product is present in the piece of luggage. A detection signal is released at an output of the computer conveying whether a liquid product was identified in the piece of luggage. The detection signal may, for example, be used in rendering a visual representation of the piece of luggage on a display device to convey information to an operator as to the presence of a liquid product in the piece of luggage.

摘要： A flow cell is provided for the analysis and/or microscopy of liquid or gas samples on the nanometer to micron scale. The flow cell preferably includes a thin membrane that is transparent to electrons and/or photons, thereby enabling the penetration of electrons or photons into a liquid flowing through the cell. Trenches are provided on either side of the membrane, which advantageously minimize fluidic resistance outside of the window area of the cell and also enable a faster response time in response to changes in external fluidic pressure. This feature enables active feedback using pathlength sensitive probes to stabilize the fluid flow to thin streams from nanometer to micron scale thicknesses with nanometer precision.

摘要： A method to perform security screening at an airport on hand-carried baggage. The method includes requesting passengers with hand carried baggage to remove from the baggage a container that holds a liquid and perform an x-ray inspection on the hand carried baggage and on the container while the container remains outside the baggage. According to the method, the results of the x-ray inspection are used to determine if the baggage contains illegal objects and if the liquid is a security threat.

摘要： Disclosed are a method and a device for security-inspection of liquid articles with dual-energy CT imaging. The method comprises the steps of obtaining one or more CT images including physical attributes of liquid article to be inspected by CT scanning and a dual-energy reconstruction method; acquiring the physical attributes of each liquid article from the CT image; and determining whether there are drugs concealed in the inspected liquid article based on the difference between the acquired physical attributes and reference physical attributes of the inspected liquid article. The CT scanning can be implemented by a normal CT scanning technique, or a spiral CT scanning technique. In the normal CT scanning technique, the scan position can be preset, or set by the operator with a DR image, or set by automatic analysis of the DR image.
