  • Publication number: 20240273454
    Abstract: A system to control the operation of monitoring devices associated with shipments is disclosed. The system comprises multiple monitoring devices installed in container(s) associated with a shipment, where a unique trip-id is assigned to each monitoring device. The monitoring devices are configured to be switched between a first mode, and a second mode. The monitoring device in the first mode transmits a set of beacon signals comprising data pertaining to the trip-id and a status indicative of the first mode. The monitoring device in the second mode detects and extracts the trip-id and the status from the detected beacon signals. The monitoring device in the second mode automatically switches to the first mode upon a negative matching of the extracted status and the status of the corresponding monitoring device and a positive matching of the extracted tri-id and the trip-id of the corresponding monitoring device.

  • Patent number: 11981662
    Abstract: The inventors have used a differential nuclear staining (DNS) assay to discover compounds with cytotoxic activity against the CEM cell line that has been determined to be highly sensitive to a variety of anti-cancer compounds. Compounds were synthesized based on a pyrazole backbone structure. Several newly synthesized compounds have been tested to identify the compounds with highest activity. One compound identified is the SSK-3 compound which has been tested on cancer cell lines and determined that it induced apoptosis via phosphatidylserine membrane exposure and activation of caspase 3 in the CEM lymphoma cell line.

  • Publication number: 20230290925
    Abstract: Silicon oxide based materials, including composites with various electrical conductive compositions, are formulated into desirable anodes. The anodes can be effectively combined into lithium ion batteries with high capacity cathode materials. In some formulations, supplemental lithium can be used to stabilize cycling as well as to reduce effects of first cycle irreversible capacity loss. Batteries are described with surprisingly good cycling properties with good specific capacities with respect to both cathode active weights and anode active weights.

  • Patent number: 11646407
    Abstract: Composite silicon based materials are described that are effective active materials for lithium ion batteries. The composite materials comprise processed, e.g., high energy mechanically milled, silicon suboxide and graphitic carbon in which at least a portion of the graphitic carbon is exfoliated into graphene sheets. The composite materials have a relatively large surface area, a high specific capacity against lithium, and good cycling with lithium metal oxide cathode materials. The composite materials can be effectively formed with a two-step high energy mechanical milling process. In the first milling process, silicon suboxide can be milled to form processed silicon suboxide, which may or may not exhibit crystalline silicon x-ray diffraction. In the second milling step, the processed silicon suboxide is milled with graphitic carbon. Composite materials with a high specific capacity and good cycling can be obtained in particular with balancing of the processing conditions.
