Abstract: Methods of forming a liquid crystal blue phase from composite materials comprising a chiral nematic liquid crystal host and an azobenzene-based bent-shape molecule are described. The composite materials quickly transfer from the liquid crystal blue phase to an isotropic phase under electromagnetic radiation and transfer from the isotropic phase to the liquid crystal blue phase when electromagnetic radiation is removed.

Abstract: A transcription regulation system based on CRISPRi and CRISPRa, and an establishment method therefor and the use thereof. The system is a new transcription regulation system which has high expression intensity, a low leakage level and is flexible and programmable. Provided is a method for achieving high-intensity and low-leakage expression of a gene by means of the transcription regulation system, wherein a high-intensity transcription level is achieved while suppressing background expression by means of synergistic regulation on downstream signaling effect devices by means of CRISPRi and CRISPRa dev ices. The new transcription regulation system can obtain, by means of loading different input promoters, a new expression system for responding to a specific signal, and has application value in the development and establishment of an efficient heterologous protein expression platform and a microbial cell factory.

Abstract: Disclosed are a fluidized bed separation method and device for methanol-to-olefins quenched water. The method may subject quenched water to liquid-solid separation via a micro-cyclone separator. The method may also subject clear liquid from the micro-cyclone separator to a secondary separation via a fluidized bed separator, then sending the same to an olefin separation device, then recovering some waste heat of the quenched water, and then returning the same to a quenching tower after performing heat exchange. The method may also regenerate a separation medium by reversely feeding stripping tower purified water or quenched water, so as to release catalyst particles absorbed by the separation medium. The method may also send a catalyst slurry concentrated by the micro-cyclone separator and the fluidized bed separator to a filter-press unit for filter-press dehydration, so as to recover a catalyst.
