3Impact frequency variation of self-excited oscillation pulsed supercritical carbon dioxide jets显示文摘In order to obtain the impact frequency of resonant coal breaking by self-excited oscillation pulsed supercritical carbon dioxide(SC-CO_(2))jet,large eddy simulation was used to analyze the formation and development process of self-excited oscillation pulsed SC-CO_(2)jet,the variation of jet impact frequency in the nozzle and the free flow field,and the variation of jet impact frequency at different positions in the jet axis and under different cavity lengths.The test device of jet impact frequency was developed,and experiments were performed to verify the conclusions of the numerical simulations.The results show that the frequency of the self-excited oscillation pulsed SC-CO_(2)jet is different in the nozzle and the free flow field.In the nozzle,the frequency generated by the fluid disturbance is the same,and the jet frequency at the exit of the nozzle is consistent with that inside the nozzle.In the free flow field,due to the compressibility of CO_(2),the pressure,velocity and other parameters of SC-CO_(2)jets have obvious fluctuation patterns.This feature causes the impact frequency of the self-excited oscillation pulsed SC-CO_(2)jet to decrease gradually in the axis.Changing the cavity length allows the adjustment of the jet impact frequency in the free flow field by affecting the disturbance frequency of the self-excited oscillation pulsed SC-CO_(2)jet inside the nozzle.SHEN Helian LIU Yong WEI Jianping QIU Liming LI Haichao DENG Yujie 2023Petroleum Exploration and Development2023,50,5:0
4Analysis of the Immune Response by Standardized Whole‑Blood Stimulation with Metabolism Modulation显示文摘The immune system defends the body from infection and plays a vital role in a wide range of health conditions.Metabolism afects a series of physiological processes,including those linked to the function of human immune system.Cellular metabolism modulates immune cell activation and cytokine production.Understanding the relationship between metabolism and immune response has important implications for the development of immune-based therapeutics.However,the deployment of large-scale functional assays to investigate the metabolic regulation of immune response has been limited by the lack of standardized procedures.Here,we present a protocol for the analysis of immune response using standardized whole-blood stimulation with metabolism modulation.Diverse immune stimuli including pattern recognition receptor(PRR)ligands and microbial stimuli were incubated with fresh human whole blood.The metabolic inhibitors were used to modulate metabolic status in the immune cells.The variable immune responses after metabolic interventions were evaluated.We described in detail the main steps involved in the whole-blood stimulation and cytokines quantifcation,namely,collection and treatment of whole blood,preparation of samples and controls,cytokines detection,and stimulation with metabolic interventions.The metabolic inhibitors for anabolic pathways and catabolic pathways exert selective efects on the production of cytokines from immune cells.In addition to a robust and accurate assessment of immune response in cohort studies,the standardized whole-blood stimulation with metabolic regulation might provide new insights for modulating immunity.Jialin Zhao Xuling Han Helian Li Yali Luo Yan Fang Yun Wang Jian Gao Yiran Zhao Jingxuan Han Feng Qian 2024Phenomics2024,4,1:0
5Deep Immunophenotyping of Human Whole Blood by Standardized Multi‑parametric Flow Cytometry Analyses显示文摘Immunophenotyping is proving crucial to understanding the role of the immune system in health and disease.High-through-put flow cytometry has been used extensively to reveal changes in immune cell composition and function at the single-cell level.Here,we describe six optimized 11-color flow cytometry panels for deep immunophenotyping of human whole blood.A total of 51 surface antibodies,which are readily available and validated,were selected to identify the key immune cell populations and evaluate their functional state in a single assay.The gating strategies for effective flow cytometry data analysis are included in the protocol.To ensure data reproducibility,we provide detailed procedures in three parts,including(1)instrument characterization and detector gain optimization,(2)antibody titration and sample staining,and(3)data acquisition and quality checks.This standardized approach has been applied to a variety of donors for a better understanding of the complexity of the human immune system.Jian Gao Yali Luo Helian Li Yiran Zhao Jialin Zhao Xuling Han Jingxuan Han Huiqin Lin Feng Qian 2023Phenomics2023,3,3:0
6Strategies and methods for fabricating high quality metal halide perovskite thin films for solar cells显示文摘With the development of human society,the problems of environmental deterioration and energy shortage have become increasingly prominent.In order to solve these problems,metal halide perovskite solar cells(PSCs)stand out because of their excellent properties(i.e.,high optical absorption coefficient,long carrier lifetime and carrier diffusion length,adjustable band gap)and have been widely studied.PSCs with low cost,high power conversion efficiency and high stability are the future development trend.The quality of perovskite film is essential for fabricating PSCs with high performance.To provide a full picture of realizing high performance PSCs,this review focuses on the strategies for preparing high quality perovskite films(including antisolvent,Lewis acid-base,additive engineering,scaleable fabrication,strain engineering and band gap adjustment),and therefore to fabricate high performance PSCs and to accelerate the commercialization.Helian Sun Pengfei Dai Xiaotong Li Jinyan Ning Shenghao Wang Yabing Qi 2021Journal of Energy Chemistry2021,30,9:0
