Abstract: A pet litter scoop assembly and a litter sieve are related, the pet litter scoop assembly including the litter sieve for collecting used litter. The litter sieve includes a base part and a handle extending from the base part, the base part including a bottom wall and a sidewall extending upwardly from the bottom wall, with a sieving cavity formed by the sidewall and the bottom wall, the handle connected to the sidewall. The litter sieve includes holes penetrating the bottom wall and sized such that the used litter cannot pass through the holes, and at least one guiding rib(s) protruding from the bottom wall to the sieving cavity and positioned adjacent to the holes to guide unused litter pellets in the sieving cavity to pass through the holes. The litter sieve and litter scoop assembly can help to avoid blocking of the holes.

Abstract: A method for preparing Mg-RE alloys with high strength and ductility using selective laser melting (SLM) additive manufacturing technology includes the following steps of: A. preparing Mg-RE-(Zn)—Zr pre-alloyed spherical powder by gas atomization; B. molding the Mg-RE-(Zn)—Zr pre-alloyed spherical powder using SLM to obtain the Mg-RE alloys with high strength and ductility; and C. conducting heat treatment on the Mg-RE alloys prepared in step B: solid solution+aging treatment or only aging treatment The method adjusts and controls microstructure and mechanical properties of the alloys by adjusting and controlling process parameters of SLM (laser power, scanning speed, hatch spacing, spot diameter, layer thickness, interlayer rotation angle, substrate preheating temperature, partition width and overlapping area width) and process parameters of subsequent heat treatment (temperature and time) to prepare the Mg-RE-(Zn)—Zr alloys with high strength and ductility using SLM process for the first time.

Abstract: A Pseudomonas monteilii strain with salinity-alkalinity tolerance is provided. The strain is Pseudomonas monteilii 9-2, which has been deposited in China General Microbiological Culture Collection Center (CGMCC) on Oct. 25, 2021, with an accession number of CGMCC No. 23666; and an internal transcribed spacer (ITS) sequence is shown in SEQ ID NO: 1. This application further provides an application of the Pseudomonas monteilii strain in the degradation of petroleum hydrocarbons in a saline-alkali environment.
