    Journal of Renewable Materials, Vol.11, No.11, pp. 3945-3956, 2023, DOI:10.32604/jrm.2023.027544

    Abstract The aim of this study is to enhance the value and utilization of red mud generated in the Bayer process by preparing composite cement mortars. The effects of two different types of Bayer red mud with varying physical and chemical characteristics on the fluidity, mechanical strength, mineral composition, and microstructure of the composite cement mortar were systematically evaluated. The results showed that the optimal addition of red mud A was 10 wt%, while it was 20 wt% for red mud B. The mechanical properties of the composite cement mortar met the standards for P·O42.5 cement.

    Fluidity Influencing Factor Analysis and Ratio Optimization of New Filling Slurry Based on the Response Surface Method

    Guanfeng Chang, Xinzhu Hua*, Xiao Liu, Chen Li, Enqian Wang, Bingjun Sun

    Journal of Renewable Materials, Vol.10, No.5, pp. 1439-1458, 2022, DOI:10.32604/jrm.2022.018607

    Abstract The filling mining method is important in realizing the green mining of mineral resources. Aiming at the problems of land resource occupation, environmental pollution, and rational utilization of coal-based solid wastes such as coal gangue, fly ash, and desulfurization gypsum, a new paste filling material was developed with coal gangue, fly ash, and desulfurization gypsum as raw materials. The microstructure of the raw materials was analyzed by XRD and SEM. Combined with the Box-Behnken experimental design, the effect of each component on the fluidity of the filling slurry was analyzed through the response surface analysis.… More > Graphic Abstract

    Membrane fluidity regulates high shear stress-induced FAK activation at different subcellular compartments


    BIOCELL, Vol.41, No.2-3, pp. 45-54, 2017, DOI:10.32604/biocell.2017.41.045

    Abstract Focal adhesion kinase (FAK) plays a vital role in mediating the adaptability of tumor cells under mechanical stimuli. Previous studies revealed that FAK can locate to different cell compartments, and its regulation is highly dependent on its subcellular localization. However, the local FAK activities and its regulation mechanism in different cell compartments of tumor cells in response to fluid shear stress are still unclear. In this study, 5 dyn/cm2 and 20 dyn/cm2 of shear stress was applied to HeLa cells for 30 min. The activities of FAK targeting different subcellular compartments (lipids rafts, non-rafts, focal adhesions… More >
