  • Patent number: 11664500
    Abstract: The present invention relates to a range of halide organic salts and their use in a cathode of an electrical cell and in batteries. Elemental halides have attracted intense interest as promising electrodes for energy storage. However, they suffer from a number of inherent physicochemical drawbacks, including the volatility of iodine, the corrosiveness of liquid bromine. The salts of the present invention may serve as a cathode matched with a zinc anode avoiding these issues.

  • Publication number: 20230126413
    Abstract: A method of assessing the brain lymphatic or glymphatic system and the glucose transporter function on blood-cerebrospinal fluid barrier (BCSFB) of a subject using D-glucose or a D-glucose analog. A spatial map is generated of water MR signals that are sensitized to changes in D-glucose or a D-glucose analog in cerebrospinal fluid (CSF) of the subject. The spatial map is observed at one or more time points before, one or more time points during, and one or more time points after, raising the blood level of the D-glucose or a D-glucose analog in the subject CSF. A difference is detected between the MR signals of the spatial map before, during, and after raising the blood level of D-glucose or a D-glucose analog. A physiological parameter associated with the brain lymphatic or glymphatic system and the glucose transporter function on BCSFB of the subject is ascertained based on the detected difference.
