“…RSM is a widely used optimization tool in the scientific community for studying the parameters that influence the process of MICP. By employing an appropriate experimental design, the number of required experiments can be reduced, allowing for the prediction of optimal performance conditions (Kumar and Kumar, 2021;Wang et al, 2021;Wang R. S. et al, 2022). To establish the relationship between the parameters and the quantity of CaCO 3 precipitation, the variation of factor levels was tested using RSM.…”

In this study, a highly promising bacterium was isolated from sandstone oil in the Ordos Basin, named strain NS-6 which exhibited exceptional urease production ability and demonstrated superior efficiency in inducing the deposition of calcium carbonate (CaCO3). Through morphological and physiochemical characteristics analysis, as well as 16S rRNA sequencing, strain NS-6 was identified as Neobacillus mesonae. The activity of urease and the formation of CaCO3 increased over time, reaching a maximum of 7.9 mmol/L/min and 184 mg (4.60 mg/mL) respectively at 32 h of incubation. Scanning Electron Microscopy (SEM) revealed CaCO3 crystals ranging in size from 5 to 6 μm, and Energy Dispersive X-ray (EDX) analysis verified the presence of calcium, carbon, and oxygen within the crystals. X-ray Diffraction (XRD) analysis further confirmed the composition of these CaCO3 crystals as calcite and vaterite. Furthermore, the maximum deposition of CaCO3 by strain NS-6 was achieved using response surface methodology (RSM), amounting to 193.8 mg (4.845 mg/mL) when the concentration of calcium ions was 0.5 mmol/L supplemented with 0.9 mmol/L of urea at pH 8.0. Genome-wide analysis revealed that strain NS-6 possesses a chromosome of 5,736,360 base pairs, containing 5,442 predicted genes, including 3,966 predicted functional genes and 1,476 functionally unknown genes. Genes like ureA, ureB, and ureC related to urea catabolism were identified by gene annotation, indicating that strain NS-6 is a typical urease-producing bacterium and possesses a serial of genes involved in metabolic pathways that mediated the deposition of CaCO3 at genetic level.

In order to obtain better quality workpiece in the process of reciprocating magnetorheological polishing. In this paper, the analysis method of abrasive particle trajectory was adopted. The effect of abrasive particle trajectory on machining quality under two reciprocating working conditions of constant speed and variable speed was studied by simulation analysis of abrasive particle trajectory under different parameters. Then the processing uniformity of workpiece under the working condition of variable speed reciprocating motion is tested by experiment. The results showed that under the condition of variable speed reciprocating motion, theabrasive particle trajectory is more complicated, and it was easier to obtain the uniforml workpiece. The experimental results of the height difference of workpiece measuring points were between 4 and 11 μm, and the height difference of equal radial measuring points is not more than 1.5 μm by experimental verification.

“…Magnetorheological polishing (MRP) is a kind of ultraprecision machining technology to remove materials on the workpiece surface by using the magnetorheological effect (MR effect) of MRP fluids in a magnetic field (Wang et al , 2022a; Kim et al , 2018; Xiu et al , 2018). It is different from the traditional polishing technologies, such as high-quality polishing, no subsurface damage and good processing adaptability of complex surfaces (Zhang et al , 2020; Iqbal and Jha, 2019).…”

Purpose This paper aims to study the effects of the processing parameters in the reciprocating magnetorheological polishing (RMRP) on abrasive particle trajectory by the simulation analysis, which provides a basis for the machining uniformity of the workpiece. Design/methodology/approach The principle of the RMRP method is discussed, and a series of simulation analysis of the abrasive particle trajectory are performed to evaluate the effects of the workpiece’s rotational speed, the eccentric wheel’s rotational speed, the eccentricity and the frame gap on abrasive particle trajectory by using the RMRP method. Findings The processing parameters have a significant influence on the abrasive particle trajectory, and then the machining uniformity of the workpiece is affected. Under certain experimental conditions, the height difference of workpiece measuring points varies between 4 and 11 µm, and the height difference of equal radial measuring points is less than 1.5 µm by optimizing processing parameters. Originality/value In this study, the optimal processing parameters can be obtained by the simulation analysis of abrasive particle trajectory, which can replace the experimental methods to obtain the reasonable processing parameters for the machining uniformity of the workpiece. It provides references for the selection of processing parameter values in magnetorheological polishing process.
