Asymmetric breakup of a droplet in an axisymmetric extensional flow

引用

Chinese Journal of Chemical engineering 2016年第1期24卷 63-70页

作者： Dongming Yu Manman Zheng Taoming Jin Jingtao Wang School of Chemical engineering and Technology Tianjin University sinopec shanghai engineering co. Ltd.

The asymmetric breakups of a droplet in an axisymmetric cross-like microfluidic device are investigated by using a three-dimensional volume of fluid(VOF) multiphase numerical model. Two kinds of asymmetries(droplet location deviation from the symmetric geometry center and different flow rates at two symmetric outlets) generate asymmetric flow fields near the droplet, which results in the asymmetric breakup of the latter. Four typical breakup regimes(no breakup, one-side breakup, retraction breakup and direct breakup) have been *** regime maps are plotted to describe the transition from one regime to another for the two types of different asymmetries, respectively. A power law model, which is based on the three critical factors(the capillary number,the asymmetry of flow fields and the initial volume ratio), is employed to predict the volume ratio of the two unequal daughter droplets generated in the direct breakup. The influences of capillary numbers and the asymmetries have been studied systematically in this paper. The larger the asymmetry is, the bigger the oneside breakup zone is. The larger the capillary number is, the more possible the breakup is in the direct breakup zone. When the radius of the initial droplet is 20 μm, the critical capillary numbers are 0.122, 0.128, 0.145,0.165, 0.192 and 0.226 for flow asymmetry factor AS= 0.05, 0.1, 0.2, 0.3, 0.4 and 0.5, respectively, in the flow system whose asymmetry is generated by location deviations. In the flow system whose asymmetry is generated by two different flow rates at two outlets, the critical capillary numbers are 0.121, 0.133, 0.145, 0.156 and 0.167 for AS= 1/21, 3/23, 1/5, 7/27 and 9/29, respectively.

Science China Chemistry 2025年

作者： Youtong Wu Xueting Li Yiwen Li Hao Wang Yuqi Zhang Xihua Lu co.lege of Chemistry and Chemical engineering Donghua University Fujian Nano-Micro Advanced Materials Sci.& Tech.co.Ltd. Jinjiang Innovation Entrepreneurship and Creativity Park shanghai Evanston Advanced Materials Sci.& Tech.co.Ltd.

In recent years, thermochromic smart windows have played an important role in enhancing energy efficiency and co.tributing to carbon neutrality in building energy co.sumption. However, thermal-shielding smart windows with high visible light modulation and structural co.ors are rarely reported. This study focuses on the development of thermochromic smart windows utilizing poly（N-isopropylacrylamide）(PNIPAm)-based nanogels, which exhibit dynamic solar modulation and high visible light transmission without additional energy input. Unlike traditional electrochromic materials such as tungsten trioxide, these smart windows achieve structural co.or states through the self-assembly of nanogels, eliminating the need for inorganic materials. The fabricated hydrogel co.tains thermo-responsive poly（N-isopropylacrylamide-random-acrylic acid-random-N-tert-butyl acrylamide）P（NIPAm-r-AA-r-TBA）(PNTA) nanogels with tunable phase transition temperatures（Tp） that align with ambient *** smart windows demonstrate excellent stability over 100 heating-co.ling cycles and significant temperature regulation,achieving an indoor temperature modulation of 10 °C and energy savings of 14.24 KJ m-3co.pared with normal windows. The production process is simple and scalable, making it feasible for industrial applications. Furthermore, these smart windows offer additional functionalities such as information encryption, adding value to their practical application.

AZD1775 synergizes with SLC7A11 inhibition to promote ferroptosis

Tumor suppressor p53-mediated cell cycle arrest and DNA damage repair may exert cytoprotective effects against cancer therapies, including WEE1 inhibition. co.sidering that p53 activation can also lead to multiple types of cell death, the role of this tumor suppressor in WEE1 inhibitor-based therapies remains disputed. In this study, we reported that nucleolar stress-mediated p53 activation enhanced the WEE1 inhibitor AZD1775-induced ferroptosis to suppress lung cancer growth. Our findings showed that AZD1775 promoted ferroptosis by blocking cystine uptake, an action similar to that of Erastin. Meanwhile, inhibition of WEE1 by the WEE1 inhibitors or si RNAs induced co.pensatory upregulation of SLC7A11, which co.ferred resistance to ferroptosis. Mechanistically, AZD1775 prevented the enrichment of H3K9me3, a histone marker of transcriptional repression, on the SLC7A11 promoter by repressing the expression of the histone methyltransferase SETDB1, thereby enhancing NRF2-mediated SLC7A11 transcription. This finding was also validated using the H3K9me3 inhibitor BRD4770. Remarkably, we found that the nucleolar stress-inducing agent Actinomycin D(Act. D) inhibited SLC7A11 expression by activating p53, thus augmenting AZD1775-induced ferroptosis. Moreover, the co.bination of AZD1775 and Act. D synergistically suppressed wild-type p53-harboring lung cancer cell growth both in vitro and in vivo. Altogether, our study demonstrates that AZD1775 promotes ferroptosis by targeting cystine uptake but also mediates the adaptive activation of SLC7A11 through the WEE1-SETDB1 cascade and NRF2-induced transcription, and inhibition of SLC7A11 by Act. D boosts the anti-tumor efficacy of AZD1775 by enhancing ferroptosis in cancers with wild-type p53.
