    Novel Micromixer with Complex 3D-Shape Inner Units: Design, Simulation and Additive Manufacturing

    Di Wang1, Guangzhao Ye1, Jingming Mai2, Xiaomin Chen1, Yongqiang Yang1,*, Yang Li1,*, Xiaojun Chen1, Jie Chen1

    CMES-Computer Modeling in Engineering & Sciences, Vol.123, No.3, pp. 1061-1077, 2020, DOI:10.32604/cmes.2020.09842

    Abstract In this paper, a novel micromixer with complex 3D-shape inner units was put forward and fabricated by metal Additive Manufacturing (AM). The design of the micromixer combined the constraints of selective laser melting technology and the factors to improve mixing efficiency. Villermaux-Dushman reaction system and Compute Fluid Design (CFD) simulation were conducted to investigate the performance and the mechanism of this novel micromixer to improve mixing efficiency. The research found that the best mixing efficiency of this novel micromixer could be gained when the inner units divided fluid into five pieces with a uniform volume. Compared with a conventional micromixer… More >

    Localization and compartmentation of Al in the leaves and roots of tea plants

    Hajiboland R1,2, C Poschenrieder3

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 86-100, 2015, DOI:10.32604/phyton.2015.84.086

    Abstract Under acid soil conditions, solubility of aluminum (Al) increases leading to toxicity for plants. Al accumulator species such as tea, however, accumulate high levels of Al in tissues without toxicity symptoms. In this work, Al localization and compartmentation were studied in tea [Camellia sinensis (L.) O. Kuntze] grown hydroponically at 0 or 100 µM Al for eight weeks. Plant dry matter production was significantly higher in the presence of Al and accumulated up to 1.21 and 6.18 mg Al/g DW in the leaves and roots, respectively. About 40-50% of Al was partitioned into cell wall (CW)-bound fraction without any difference… More >
