Abstract: A method for making barium titanate nanopowders, includes mixing barium salt, titanium source, carbohydrate, and urea in a container according to a first ratio, stirring the barium salt, the titanium source, the carbohydrate, and the urea in the container under a heating condition approximately from 60° C. to 120° C. to obtain a molten mixture, heating the molten mixture to dehydrate and carbonize the carbohydrate to obtain a dark brown solid, and performing a heat treatment on the dark brown solid to obtain the barium titanate nanopowders.

Abstract: A fully homomorphic encryption method based on modular operation, the method including: acquiring a plaintext of any numerical value data type in an encryption process and converting the plaintext to a corresponding plaintext system plaintext according to an encryption requirement; performing an encryption operation on each number in the system plaintext, and combining ciphertexts acquired by the encryption operation to obtain a corresponding ciphertext combination; performing a ciphertext operation on the ciphertext combination using a ciphertext source code, a ciphertext radix-minus-one complement, and a ciphertext complement code based on modular encryption; and using modular division to decrypt a result of the ciphertext operation to obtain a decrypted plaintext.

Abstract: Aralkyl diamine derivative of the following formula, pharmaceutically acceptable salts or uses thereof as antidepressants. The derivatives have triplex inhibiting activities of the reuptake of 5-HT, dopamine and noradrenalin, which can be administered to the patients in need of such treatment in the form of compositions orally or injectedly et al.
