  • Publication number: 20250019780
    Abstract: The present invention is directed to a method of determining DNA concentration in a DNA virus. The invention features three basic steps. The initial step is the specific capture of a defined amount of virus capsid particles on a first solid phase. The second step is lysis of the capsid to release the virus DNA from the first solid phase into a lysis solution. After separating the lysis solution from the first solid phase, the third step is contacting the lysis solution with a second solid phase. The second solid phase captures total DNA derived from the captured capsid. The present invention is also directed to a method for measuring the percentage of full virus capsid, comprising first determining the ssDNA concentration in viruses, and then converting the ssDNA concentration to percentage of full virus capsid using a calibration curve having DNA concentration plotted against standards of % of full capsids.

  • Patent number: 12100850
    Abstract: This disclosure relates generally to an apparatus for organizing battery cells. The apparatus includes a block including: sleeves forming chambers, a first sheet configured to locate the sleeves, and a foam structure surrounding the sleeves. Each chamber is configured to accommodate a battery cell. The block is configured to: organize the battery cells into battery cell groups, separate each battery cell group from its adjacent battery cell groups using a thermally insulating material, and prevent gas from entering into each battery cell group from its adjacent battery cell groups. Each battery cell group includes a plurality of the battery cells, each of the battery cells in the battery cell group is adjacent to at least another of the battery cells in the battery cell group. Each battery cell group is adjacent to at least another battery cell group.

  • Patent number: 11936017
    Abstract: A battery pack for an electric vehicle or a hybrid vehicle may include a housing, a stack of battery cells disposed within the housing, and a cooling subassembly. The housing typically holds the cell stack together, and the cooling subassembly typically cools the cell stack to prevent damage to the battery cells and to maintain the performance of the battery cells. The cooling subassembly may include a cold plate defining a liquid flow channel and one or more thermoelectric devices (TEDs) that are operable to cool the cell stack when current is supplied thereto. Heat spreaders may be employed within the battery pack, and exemplary configurations of components to thermally and mechanically couple the cooling subassembly are described.

  • Publication number: 20240075146
    Abstract: The present disclosure provides an integrated target assembly containing a lithium layer attached to a base plate on a support structure made from a low-activation material. The support structure includes flow channels adjacent to the surface of the base plate for effective cooling of the base plate during operation. The integrated target assembly advantageously reduces the amount of easily activatable material, such as copper, leading to increased safety of the handling personnel.
