Abstract: A storage device for data encryption and self-destruction includes a controller, an interface module, a storage module, an encryption and authentication module, a positioning module, a power supply module, and a communication and self-destruction module. The interface module, the storage module, the encryption and authentication module, the positioning module and the communication and self-destruction module are electrically connected to the controller, respectively. The encryption and authentication module is configured to encrypt and protect data stored in the storage module, and authenticate a request for remote access to the storage device. The communication and self-destruction module is configured to send position information acquired by the positioning module to a storage device management system, receive and execute a data destruction instruction issued by the storage device management system, and destruct the data stored in the storage module.

Abstract: The present disclosure provides an epoxidized natural rubber composite and a preparation process thereof, and relates to the technical field of rubber materials. The epoxidized natural rubber composite provided by the present disclosure comprises the following preparation raw materials in parts by weight: 100 parts of epoxidized natural rubber, 1˜30 parts of peanut meal, 0.05˜0.8 parts of surfactants, 0.1˜4 parts of coagulant and 0.2˜12 parts of vulcanization processing aids. The present disclosure utilizes essential amino acids and non-essential amino acids contained in peanut meal to improve the aging resistance of the epoxidized natural rubber. After hot air aging, ozone aging and ultraviolet aging treatments, both the tensile strength retention rate and the elongation at break retention rate of the epoxidized natural rubber composites of the present disclosure can be kept above 83%.
Abstract: The present invention pertains to fields of biochemistry and molecular biology, relates to an ?O-superfamily conotoxin peptide, pharmaceutical composition thereof, preparation method and use thereof. The present invention further relates to a propeptide of the conotoxin peptide, nucleic acid construct thereof, expression vector and transformed cell thereof, and fusion protein thereof. The present invention further relates to a method for blocking acetylcholine receptors as well as a use of the conotoxin peptide in the manufacture of a medicament. The new ?O-superfamily conotoxin peptide of the present invention is capable of specifically blocking acetylcholine receptor (nAChRs) (e.g., ?9?10 nAChR), and NMDA receptor (e.g.
