Role of water chemistry on estrone removal by nanofiltration with the presence of hydrophobic acids

Xue JIN,Jiangyong HU

《环境科学与工程前沿（英文）》 2015年 第9卷 第1期   页码 164-170 doi: 10.1007/s11783-014-0747-9

摘要： Hydrophobic acid organic matter (HpoA) extracted from treated effluent has been known to improve the rejection of steroid hormone estrone by reverse osmosis (RO) and nanofiltration (NF) membranes. In this study, the effects of solution chemistry (solution pH and ionic strength) on the estrone rejection by NF membrane with the presence of HpoA were systematically investigated. Crossflow nanofiltration experiments show that the presence of HpoA significantly improved estrone rejection at all pH and ionic strength levels investigated. It is consistently shown that the “enhancement effect” of HpoA on estrone rejection at neutral and alkaline pH is attributed to the binding of estrone by HpoA macromolecules via hydrogen bonding between phenolic functional groups in feed solutions, which leads to an increase in molecular weight and appearance of negative charge. The membrane exhibited the best performance in terms of estrone rejection at pH 10.4 (compared to pH 4 and pH 7) as a result of strengthening the electrostatic repulsion between estrone and membrane with the presence of HpoA. At neutral pH level, the ability of HpoA macromolecules to promote estrone rejection became stronger with increasing ionic strength due to their more extended conformation, which created more chances for the association between estrone and HpoA. The important conclusion of this study is that increasing solution pH and salinity can greatly intensify the “enhancement effect” of HpoA. These results can be important for NF application in direct/indirect potable water reuse.

Hexavalent chromium in drinking water: Chemistry, challenges and future outlook on Sn(II)- and photocatalyst-based

Haizhou Liu, Xuejun Yu

《环境科学与工程前沿（英文）》 2020年 第14卷 第5期 doi: 10.1007/s11783-020-1267-4

摘要： Abstract • Wide occurrence of Cr(VI) in US source drinking water. • A strong dependence of occurrence on groundwater sources. • Elucidate Redox and equilibrium chemistry of Cr(VI). • Sn(II)-based and TiO2-based reductive treatments hold extreme promise. • Key challenges include residual waste, Cr(VI) re-generation and socioeconomic drivers. Chromium (Cr) typically exists in either trivalent and hexavalent oxidation states in drinking water, i.e., Cr(III) and Cr(VI), with Cr(VI) of particular concern in recent years due to its high toxicity and new regulatory standards. This Account presented a critical analysis of the sources and occurrence of Cr(VI) in drinking water in the United States, analyzed the equilibrium chemistry of Cr(VI) species, summarized important redox reaction relevant to the fate of Cr(VI) in drinking water, and critically reviewed emerging Cr(VI) treatment technologies. There is a wide occurrence of Cr(VI) in US source drinking water, with a strong dependence on groundwater sources, mainly due to naturally weathering of chromium-containing aquifers. Challenges regarding traditional Cr(VI) treatment include chemical cost, generation of secondary waste and inadvertent re-generation of Cr(VI) after treatment. To overcome these challenges, reductive Cr(VI) treatment technologies based on the application of stannous tin or electron-releasing titanium dioxide photocatalyst hold extreme promise in the future. To moving forward in the right direction, three key questions need further exploration for the technology implementation, including effective management of residual waste, minimizing the risks of Cr(VI) re-occurrence downstream of drinking water treatment plant, and promote the socioeconomic drivers for Cr(VI) control in the future.

Where physics meets chemistry: Thin film deposition from reactive plasmas

Andrew Michelmore, Jason D. Whittle, James W. Bradley, Robert D. Short

《化学科学与工程前沿（英文）》 2016年 第10卷 第4期   页码 441-458 doi: 10.1007/s11705-016-1598-7

摘要： Functionalising surfaces using polymeric thin films is an industrially important field. One technique for achieving nanoscale, controlled surface functionalization is plasma deposition. Plasma deposition has advantages over other surface engineering processes, including that it is solvent free, substrate and geometry independent, and the surface properties of the film can be designed by judicious choice of precursor and plasma conditions. Despite the utility of this method, the mechanisms of plasma polymer growth are generally unknown, and are usually described by chemical (i.e., radical) pathways. In this review, we aim to show that plasma physics drives the chemistry of the plasma phase, and surface-plasma interactions. For example, we show that ionic species can react in the plasma to form larger ions, and also arrive at surfaces with energies greater than 1000 kJ?mol (>10 eV) and thus facilitate surface reactions that have not been taken into account previously. Thus, improving thin film deposition processes requires an understanding of both physical and chemical processes in plasma.

摘要： Benefiting from the advantage of taking place in biological environments without interfering with an innate biochemical process, the bioorthogonal reaction that commonly contains the “bond formation” and “bond cleavage” system has been widely used in targeted therapy for a variety of tumors. Herein, several prominent cases based on the bioorthogonal reaction that tailoring the metabolic glycoengineering tactics to modified cells for cancer immunotherapy, and the innovative tactics for reducing the metal ions’ toxic and side effects with microneedle patches will be highlighted. Based on these applications, the complexities, potential pitfalls, and opportunities of bioorthogonal chemistry in future cancer therapy will be evaluated.

Computational design of heterogeneous catalysts and gas separation materials for advanced chemical processing

Huaiwei Shi, Teng Zhou

《化学科学与工程前沿（英文）》 2021年 第15卷 第1期   页码 49-59 doi: 10.1007/s11705-020-1959-0

摘要： Functional materials are widely used in chemical industry in order to reduce the process cost while simultaneously increase the product quality. Considering their significant effects, systematic methods for the optimal selection and design of materials are essential. The conventional synthesis-and-test method for materials development is inefficient and costly. Additionally, the performance of the resulting materials is usually limited by the designer’s expertise. During the past few decades, computational methods have been significantly developed and they now become a very important tool for the optimal design of functional materials for various chemical processes. This article selectively focuses on two important process functional materials, namely heterogeneous catalyst and gas separation agent. Theoretical methods and representative works for computational screening and design of these materials are reviewed.

Regulating surface chemistry of separator with LiF for advanced Li-S batteries

《能源前沿（英文）》 2022年 第16卷 第4期   页码 601-606 doi: 10.1007/s11708-021-0759-7

摘要： Lithium-sulfur (Li-S) batteries have attracted intensive attention owing to their ultrahigh theoretical energy density. Nevertheless, the practical application of Li-S batteries is prevented by uncontrollable shuttle effect and retarded reaction kinetics. To address the above issues, lithium fluoride (LiF) was employed to regulate the surface chemistry of routine separator. The functional separator demonstrates a great ability to suppress active S loss and protect lithium anode. This work provides a facile strategy for the development of advanced Li-S batteries.

Undrained seismic bearing capacity of strip footing adjacent to a heterogeneous excavation

《结构与土木工程前沿（英文）》 2023年 第17卷 第4期   页码 566-583 doi: 10.1007/s11709-023-0905-x

摘要： The analysis of the bearing capacity of strip footings sited near an excavation is critical in geotechnics. In this study, the effects of the geometrical features of the excavation and the soil strength properties on the seismic bearing capacity of a strip footing resting on an excavation were evaluated using the lower and upper bounds of the finite element limit analysis method. The effects of the setback distance ratio (L/B), excavation height ratio (H/B), soil strength heterogeneity (kB/cu), and horizontal earthquake coefficient (kh) were analyzed. Design charts and tables were produced to clarify the relationship between the undrained seismic bearing capacity and the selected parameters.

Precursor-driven structural tailoring of iron oxychloride for enhanced heterogeneous Fenton activity

《化学科学与工程前沿（英文）》 2023年 第17卷 第10期   页码 1533-1543 doi: 10.1007/s11705-023-2330-z

摘要： Iron oxychloride (FeOCl) is a unique layered material with tunable electronic properties. The conventional synthetic route of chemical vapor transition involves a thermodynamics-driven gas–solid interfacial reaction which often generates macroscopic crystals with stable facets. In this study, through analyzing the effects of the synthetic parameters on the FeOCl synthesis, we discovered the dominant contribution of the α-Fe2O3 precursors on the chemical property of the FeOCl product, and subsequently developed a highly-controllable synthetic route of tailoring the FeOCl structures into small sizes and exposed high-energy facets via a facile and scalable mechanical-chemical approach. The synthesized products could be systematically tuned by the ball-milling conditions of the α-Fe2O3 precursors. With increased milling time, the FeOCl crystallites demonstrated reduced sizes and more exposed (110) facets. Intriguingly, these small-sized FeOCl catalysts exhibited much faster Fenton-like kinetics than the pristine macroscopic FeOCl materials. Specifically, FeOCl catalysts with a 12-hour milling time showed nearly 39 times higher efficiency toward phenol degradation than the pristine FeOCl. The structure-reactivity relationship was further elucidated using the combinatory analysis via density functional theory calculation, electron paramagnetic resonance and radical quenching probe experiments. This work provides a rationale for tailoring the surface structures of FeOCl crystallites for potential applications in environmental catalysis.

of herding behavior of tradable green certificate market players on market efficiency: Insights from heterogeneous

《能源前沿（英文）》 2023年 第17卷 第2期   页码 266-285 doi: 10.1007/s11708-021-0752-1

摘要： Tradable green certificate (TGC) scheme promotes the development of renewable energy industry which currently has a dual effect on economy and environment. TGC market efficiency is reflected in stimulating renewable energy investment, but may be reduced by the herding behavior of market players. This paper proposes and simulates an artificial TGC market model which contains heterogeneous agents, communication structure, and regulatory rules to explore the characteristics of herding behavior and its effects on market efficiency. The results show that the evolution of herding behavior reduces information asymmetry and improves market efficiency, especially when the borrowing is allowed. In addition, the fundamental strategy is diffused by herding evolution, but TGC market efficiency may be remarkably reduced by herding with borrowing mechanism. Moreover, the herding behavior may evolve to an equilibrium where the revenue of market players is comparable, thus the fairness in TGC market is improved.
