Abstract: The present disclosure discloses a Pichia kudriavzevii and a multifunctional complex microbial inoculant and use thereof, and belongs to the technical field of bioengineering. The Pichia kudriavzevii of the present disclosure has a degrading ability of lactic acid as high as 12.69 g·L?1, which is 2.04 times that of a type strain. At the same time, the strain can also metabolize ethanol and has an OD600 of 4.48 after fermentation in a sorghum juice medium at 30° C. and 200 rpm for 3 d. The Pichia kudriavzevii could completely consume 58 g·L?1 of glucose in the sorghum juice medium after 60 h of fermentation and produce 13.06 g·L?1 of ethanol. The Pichia kudriavzevii degrades lactic acid and can relieve a lactic acid pressure of a fermentation system and enable Saccharomyces cerevisiae to grow and metabolize to produce wine.

Abstract: Systems and methods for navigating a user to a destination are provided. An exemplary indoor navigation method uses a terminal device. The method includes capturing, by the terminal device, image data of an indoor scene, and determining a current position of the user based on the captured image data. The method also includes determining a navigation path and a navigation sign for navigating the user from the current position to the destination, and rendering, by the terminal device, a three-dimensional representation of the indoor scene with the navigation sign placed therein based on the image data and the navigation path. The navigation sign signals the navigation path in the three-dimensional representation. The method further includes displaying, on the terminal device, the three-dimensional representation to the user.

Abstract: Apparatus for making atomic layer deposition on powdered materials is provided. Inside a vacuum deposition chamber, a stationary but tilted pan-shaped vessel, or non-stationary pan-shaped vessel that is doing tilting movement continuously or intermittently, is used to accommodate powdered samples. A plowing device with teeth or blades is positioned above the pan-shaped vessel, configured to make rotary or sliding movement so as to make plowing actions to the powdered samples, thereby agitate the powdered samples on the pan-shaped vessel. A flattening structure is positioned above the pan-shaped vessel, configured to make rotary or sliding movement, thereby even out the distribution of the powdered samples. The apparatus may comprise multiple pan-shaped vessels or multiple vacuum chambers.

Abstract: Method and apparatus for making atomic layer deposition on powdered materials are provided. A rotary vessel with tilted rotation axis can be used as the deposition chamber. The rotary vessel can be directly used as the deposition chamber, or the rotary vessel is positioned inside a vacuum chamber that serves as the deposition chamber. A hallow shaft can be used to deliver rotary motion and facilitate pumping. A tube can be inserted into the hollow shaft or the rotary vessel to introduce precursors. Gas diffuser and slowly increased pumping speed can be used to reduce the agitation caused by gas flow. Intermittent rotation, variable rotary speed, extruding structures on inner surface of the rotary vessel, and the addition of easy-to-agitate powder or beads of other materials can be used to enhance the powder agitation caused by rotation.
