Multistage-batch bipolar membrane electrodialysis for base production from high-salinity wastewater

《化学科学与工程前沿（英文）》 2022年第16卷第5期页码 764-773 doi: 10.1007/s11705-021-2114-2

摘要： Bipolar membrane electrodialysis (BMED) is considered a state-of-the-art technology for the conversion of salts into acids and bases. However, the low concentration of base generated from a traditional BMED process may limit the viability of this technology for a large-scale application. Herein, we report an especially designed multistage-batch (two/three-stage-batch) BMED process to increase the base concentration by adjusting different volume ratios in the acid (V_acid), base (V_base), and salt compartments (V_salt). The findings indicated that performance of the two-stage-batch with a volume ratio of V_acid:V_base:V_salt = 1:1:5 was superior in comparison to the three-stage-batch with a volume ratio of V_acid:V_base:V_salt = 1:1:2. Besides, the base concentration could be further increased by exchanging the acid produced in the acid compartment with fresh water in the second stage-batch process. With the two-stage-batch BMED, the maximum concentration of the base can be obtained up to 3.40 mol∙L^–1, which was higher than the most reported base production by BMED. The low energy consumption and high current efficiency further authenticate that the designed process is reliable, cost-effective, and more productive to convert saline water into valuable industrial commodities.

Aerodynamic design by jointly applying S2 flow surface calculation and modern optimization methods on multistage

ZHAO Honglei, WANG Songtao, HAN Wanjin, FENG Guotai

《能源前沿（英文）》 2008年第2卷第1期页码 93-98 doi: 10.1007/s11708-008-0007-4

摘要： A three-stage axial turbine was redesigned by jointly applying S2 flow surface direct problem calculation methods and multistage local optimization methods. A genetic algorithm and artificial neural network were jointly adopted during optimization. A three-dimensional viscosity Navier–Stokes equation solver was applied for flow computation. H-O-H-topology grid was adopted as computation grid, that is, an H-topology grid was adopted for inlet and outlet segment, whereas an O-topology grid was adopted for stator zone and rotor zone. Through the optimization design, the total efficiency increases 1.1%, thus indicating that the total performance is improved and the design objective is achieved.

Multistage analysis method for detection of effective herb prescription from clinical data

null

《医学前沿（英文）》 2018年第12卷第2期页码 206-217 doi: 10.1007/s11684-017-0525-8

摘要：

Determining effective traditional Chinese medicine (TCM) treatments for specific disease conditions or particular patient groups is a difficult issue that necessitates investigation because of the complicated personalized manifestations in real-world patients and the individualized combination therapies prescribed in clinical settings. In this study, a multistage analysis method that integrates propensity case matching, complex network analysis, and herb set enrichment analysis was proposed to identify effective herb prescriptions for particular diseases (e.g., insomnia). First, propensity case matching was applied to match clinical cases. Then, core network extraction and herb set enrichment were combined to detect core effective herb prescriptions. Effectiveness-based mutual information was used to detect strong herb–symptom relationships. This method was applied on a TCM clinical data set with 955 patients collected from well-designed observational studies. Results revealed that groups of herb prescriptions with higher effectiveness rates (76.9% vs. 42.8% for matched samples; 94.2% vs. 84.9% for all samples) compared with the original prescriptions were found. Particular patient groups with symptom manifestations were also identified to help investigate the indications of the effective herb prescriptions.

具有聚集诱导发光活性的抗冻水凝胶用于低温环境下多级信息的加密和解密 Article

睢晓洁, 汪晓东, 蔡诚诚, 马君怡, 杨静, 张雷

《工程（英文）》 2023年第23卷第4期页码 82-89 doi: 10.1016/j.eng.2022.03.021

摘要：

抗冻水凝胶可以在零下温度环境中调节内部水分子的冻结行为，从而保持其优异特性（如智能响应性和液体运输）以及拓展其在寒冷条件下的应用。本文开发了一系列具有聚集诱导发光（AIE）活性的抗冻水凝胶，可实现在零下温度的信息加密和解密。通过改变水凝胶内的甜菜碱含量，该水凝胶可呈现出不同的冻结温度（T_f）。当温度高于/低于T_f时，编码于水凝胶内的AIE荧光分子不发射/发射荧光，从而可以实现信息的加密和解密。此外，通过调控水凝胶的冻结程序或者在水凝胶内原位引入具有光热效应的硫化铜纳米颗粒并结合特定的照射条件，可以实现信息的多级加密和解密，从而增强信息的安全性。最后，由于解密的信息图案对温度波动具有不可逆性，因此该具有AIE活性的抗冻水凝胶可作为无需外界供能的防伪标签，用于实时和可视化监测冷冻运输（−80 ℃）过程中生物样本（如间充质干细胞和红细胞）的活性。
