Abstract: The application provides an air purifier comprising a shell assembly having air inlets and air outlets, and a filter assembly, an air inflow guide assembly, a fan and a diffusion air outflow assembly sequentially arranged from back to front. The filter assembly can purify air entering the filter assembly via the air inlets and flowing through the filter assembly. The air inflow guide assembly defines a guide channel between the filter assembly and the fan. The fan generates an air flow that flows into a first receiving cavity via the air inlets and sequentially flows through each assembly. The diffusion air outflow assembly can rotate to guide the air flow to the air outlets, enable the air flow to diffuse outwards and decrease the flow velocity of the air flow. The air purifier expands the purification range of the air purifier and improves the purification effect of the air purifier.

Abstract: Metal oxide gel particles, may be prepared with a desired particle size, by preparing a low-temperature aqueous metal nitrate solution containing hexamethylene tetramine as a feed solution; and causing the feed solution to flow through a first tube and exit the first tube as a first stream at a first flow rate, so as to contact a high-temperature nonaqueous drive fluid. The drive fluid flows through a second tube at a second flow rate. Shear between the first stream and the drive fluid breaks the first stream into particles of the metal nitrate solution, and decomposition of hexamethylene tetramine converts metal nitrate solution particles into metal oxide gel particles. A metal oxide gel particle size is measured optically, using a sensor device directed at a flow of metal oxide gel particles within the stream of drive fluid.
