The invention provides a peripheral blood mononuclear cell cryopreservation solution, a preparation method and application of the peripheral blood mononuclear cell cryopreservation solution and a peripheral blood mononuclear cell cryopreservation method, and relates to the technical field of cells. The peripheral blood mononuclear cell cryopreservation liquid comprises the following components: a permeable protective agent, a non-permeable protective agent, human serum albumin, a 1640 basal culture medium, glutathione, autologous plasma, vitamin C and heparin sodium, wherein the autologous plasma is plasma of the peripheral blood mononuclear cells. According to the technical scheme, the permeable protective agent and the non-permeable protective agent are combined, and meanwhile, the human serum albumin, the 1640 basic culture medium, the heparin sodium, the glutathione, the autologous plasma and the vitamin C are added, so that a metabolic environment in the cell cryopreservation process is provided, and the motility rate and the proliferation activity of the recovered cells are ensured.

The present invention provides a composite aerogel fiber for adaptive thermal management and dynamic display, and a preparation method and application thereof, which belongs to the field of aerogel fiber preparation. The method comprises the following steps: S1, dispersing the washed and crushed cellulose raw material and thermochromic material in a non-derivatized aqueous phase solvent, and then obtaining a cellulose spinning solution after defoaming and filtering; S2, extruding the cellulose spinning solution described in S1 into a coagulation bath through a spinneret for solvent phase separation and replacement aging to obtain a one-dimensional composite cellulose gel fiber; S3, drying the composite cellulose gel fiber obtained in S2 to obtain a composite aerogel fiber. This method can not only omit the step of water replacement of conventional gel fibers, but also the prepared composite aerogel fibers have stronger mechanical properties. At the same time, this method can also adjust the size and uniformity of micropores in the prepared aerogel.

The defoaming device comprises a headbox, the headbox comprises a lip lower plate located at the bottom of a lip of the headbox and a lip upper plate located at the top of the lip, and a pulp flowing channel is formed between the lip lower plate and the lip upper plate; a through defoaming hole is formed in the lip upper plate; the upper surface of the lip lower plate is covered with a C12 or above higher fatty alcohol defoaming agent coating with the preset thickness; and a cooling device is arranged on the lower surface of the lip lower plate and is used for cooling the higher fatty alcohol defoaming agent. The upper surface of the lip lower plate is covered with a layer of C12 or above higher fatty alcohol defoaming agent with the preset thickness, tiny bubbles in slurry firstly make contact with the upper surface of the lip lower plate, and due to the existence of the defoaming agent coating, the small bubbles are rapidly combined into large bubbles, so that the bubbles in the lip lower plate are separated from the upper surface of the lip lower plate. And bubbles are discharged from the top end by utilizing the defoaming holes of the lip upper plate, so that the aim of simply and continuously defoaming is fulfilled on the premise of not influencing other structures of the headbox and not adding an additional defoaming agent.

This invention discloses an IoT chip module encapsulation conveying device, including a CNC guide rail and a carrier block. A laterally movable mounting plate is installed on the CNC guide rail, and a rack is fixedly connected to one side of the CNC guide rail. An air supply mechanism is installed on the mounting plate, and the rack is drivenly connected to the air supply mechanism. A first sliding groove is formed on the mounting plate, and a locking block is provided on the carrier block. This IoT chip module encapsulation conveying device, through the setting of a buffer mechanism, allows the carrier block to slide along the first sliding groove due to inertia the instant the mounting plate stops. The buffer mechanism can buffer the carrier block, thereby reducing the possibility of the encapsulant on the chip flowing out or deforming due to inertia. Through the coordinated arrangement of the rack, air supply mechanism, and buffer damping adjustment mechanism, the buffer mechanism can automatically adjust the damping magnitude according to the speed of the carrier block's movement, further improving the practicality of the device.
