The invention a fluorinated dendrimer and a preparation method thereof. The preparation method of the fluorinated dendrimer include the following steps: S1, obtaining an intermediate product by addition reaction of 4-fluoroaniline and methyl acrylate at room temperature; S2, stirring the intermediate product with 1,3-diamino-2-propanol and methyl acrylate at room temperature to obtain a mixture; S3, performing a stage heating reaction of the mixture under a reduced pressure condition to obtain the fluorinated dendrimer. The fluorinated dendrimer can solve the problems of high demulsification temperature, large dosage, and low demulsification efficiency of existing demulsifiers.

PAMAM dendrimer based CEST imaging agents, pharmaceutical compositions comprising the same and methods of uses thereof are disclosed.

A method of providing spatial diversity for critical data delivery in a beamformed mmWave small cell is proposed. The proposed spatial diversity scheme offers duplicate or incremental data/signal transmission and reception by using multiple different beams for the same source and destination. The proposed spatial diversity scheme can be combined with other diversity schemes in time, frequency, and code, etc. for the same purpose. In addition, the proposed spatial diversity scheme combines the physical-layer resources associated with the beams with other resources of the same or different protocol layers. By spatial signaling repetition to avoid Radio Link Failure (RLF) and Handover Failure (HOF), mobility robustness can be enhanced. Mission-critical and/or time-critical data delivery can also be achieved without relying on retransmission.
