Abstract: Techniques for providing a method of barcode-based mobile payment are described. One example method includes data indicative of a barcode is received from a barcode device in response to the barcode device scanning the barcode on a first client device requesting a service. Authentication information is determined from the received data indicative of the barcode that indicates whether the first client device corresponds to an account; in response to determining that the first client device corresponds to the account from the authentication information. An account limit is determined for the first client device from the account. A service requested amount is determined in the authentication information from the first client device and does not exceed the account limit. In response to determining the service requested amount does not exceed the account limit, data indicative of an acceptance of the requested service is transmitted to the first client device.

Abstract: An atomic layer deposition device for massively coating micro-nano particles, includes a reaction chamber and a particle container, in which an inlet port is provided at a lower end of the reaction chamber, and an inlet pipe for introducing a precursor or a carrier gas is provided in the inlet port; a chamber door is provided at an upper end of the reaction chamber, so that the particle container can be freely placed in or removed out of the reaction chamber; an air inlet hole is provided at a lower end of the particle container, and the inlet pipe enters the particle container through the air inlet hole.

Abstract: Apparatus and methods for binding a wearable device for use with the wearable device, a terminal, and a server are presented. The method executed by the wearable device includes providing device information to the terminal, receiving a device certificate from the server, and storing the device certificate for performing payment using the corresponding user account. The method executed by the server includes receiving a binding request from the wearable device via the terminal, generating a device certificate of the wearable device based on the device identification, and providing the device certificate to the wearable device. The method executed by the payee device includes acquiring a transaction certificate of a wearable device and sending a payment collection request to a server including the transaction certificate of the wearable device and payment sum information.

Abstract: A modular injector includes a precursor channel assembly and a seal assembly; the precursor channel assembly includes a plate-shaped base, a precursor channel and a gas pipeline; the precursor channel is disposed on a front surface of the plate-shaped base and extends from top to bottom, and a top end of the precursor channel is communicated with the gas pipeline; the seal assembly is disposed on the front surface of the plate-shaped base. The modular injector includes a plurality of components to form an integral module, and shunts and buffers the introduced gas through the precursor channel to achieve uniform deposition. A device includes multiple modular injectors arranged at an interval, into which the oxidant precursor source and the organo-metallic source are respectively introduced, so that multiple stages of film are deposited on the substrate after the substrate moves for a round trip.

Abstract: A liposomal paclitaxel palmitate formulation, including: 0.1-1% (w/v) of a paclitaxel palmitate; 1-10% (w/v) of a lecithin; 0.05-1.0% (w/v) of distearoyl phosphoethanolamine-polyethylene glycol 2000 (DSPE-PEG2000); and water. A method for preparing the formulation includes: mixing the paclitaxel palmitate, lecithin, cholesterol, DSPE-PEG2000, and an organic solvent, and heating the resulting mixture at 25-75° C. to yield an organic phase; heating an aqueous phase to 25-75° C., and stirring and adding the organic phase to the aqueous phase, to yield a crude liposome; emulsifying the crude liposome, to yield a liposome solution; adding a cryoprotector to the liposome solution, adding water to the liposome solution to reach a preset calibration, adding a pH modifier, filtering the liposome solution, and packaging.
