Abstract: The invention provides methods for microbial bioburden reduction of various chromatography matrices, including bioburden reduction in the context of large-scale Protein A-based affinity chromatography columns.

Abstract: A transaction method, a terminal device, a payment system, a merchant system, and a storage medium. The transaction method comprises: generating a payment request (101); sending the payment request in a rich media message format to a payment system (102); and receiving a payment processing result in a rich media message format from the payment system, wherein the payment processing result corresponds to the payment request (104). A user can make payment by sending and receiving rich media messages without needing to install multiple payment applications, thereby enabling convenient operation.

Abstract: Embodiments of the present application provide a payment method, a gateway device, a server and a storage medium. The method is applied to the gateway device, and the method includes: obtaining target identification information and payment amount of a target IoT device connected to the gateway device, wherein the target identification information includes a first device identification of the target IoT device and/or a feature identification of a physical layer between the target IoT device and the gateway device; sending a first payment request to the server, wherein the first payment request includes the target identification information, a second device identification of the gateway device and the payment amount, and the first payment request is configured to instruct the server to search a target payment account associated with the target identification information and the second device identification, and to deduct from the target payment account according to the payment amount.

Abstract: Provided is a prelithiation material, comprising a lithium-containing compound and an inorganic non-metallic reductive agent. Further provided is a method for preparing the prelithiation material of the present invention. Further provided is use of the prelithiation material of the present invention in a lithium ion battery. By mixing the prelithiation material provided by the present invention with a positive electrode material or coating the side of a separator near the positive electrode with the same, a battery is assembled, and during first cycle, active lithium can be released so as to compensate active lithium lost from a negative electrode. The prelithiation material provided by the present invention has a good compatibility with currently commercially available positive and negative electrodes, and is very suitable for current secondary lithium ion batteries.
