Controlling microbiological interfacial behaviors of hydrophobic organic compounds by surfactants in

ZHANG Dong,ZHU Lizhong

《环境科学与工程前沿（英文）》 2014年第8卷第3期页码 305-315 doi: 10.1007/s11783-014-0647-z

摘要： Bioremediation of hydrophobic organic compounds (HOCs) contaminated soils involves several physicochemical and microbiological interfacial processes among the soil-water-microorganism interfaces. The participation of surfactants facilitates the mass transport of HOCs in both the physicochemical and microbiological interfaces by reducing the interfacial tension. The effects and underlying mechanisms of surfactants on the physicochemical desorption of soil-sorbed HOCs have been widely studied. This paper reviewed the progress made in understanding the effects of surfactant on microbiological interfacial transport of HOCs and the underlying mechanisms, which is vital for a better understanding and control of the mass transfer of HOCs in the biodegradation process. In summary, surfactants affect the microbiological interfacial behaviors of HOCs during three consecutive processes: the soil solution-microorganism sorption, the transmembrane process, and the intracellular metabolism. Surfactant could promote cell sorption of HOCs depending on the compatibility of surfactant hydrophile hydrophilic balance (HLB) with cell surface properties; while the dose ratio between surfactant and biologic mass (membrane lipids) determined the transmembrane processes. Although surfactants cannot easily directly affect the intracellular enzymatic metabolism of HOCs due to the steric hindrace, the presence of surfactants can indirectly enhanced the metabolism by increasing the substrate concentrations.

Generating native user interfaces formultiple devices by means ofmodel transformation

Ignacio MARIN,Francisco ORTIN,German PEDROSA,Javier RODRIGUEZ

《信息与电子工程前沿（英文）》 2015年第16卷第12期页码 995-1017 doi: 10.1631/FITEE.1500083

摘要： In the last years, the types of devices used to access information systems have notably increased using different operating systems, screen sizes, interaction mechanisms, and software features. This device fragmentation is an important issue to tackle when developing native mobile service front-end applications. To address this issue, we propose the generation of native user interfaces (UIs) by means of model transformations, following the modelbased user interface (MBUI) paradigm. The resulting MBUI framework, called LIZARD, generates applications for multiple target platforms. LIZARD allows the definition of applications at a high level of abstraction, and applies model transformations to generate the target native UI considering the specific features of target platforms. The generated applications follow the UI design guidelines and the architectural and design patterns specified by the corresponding operating system manufacturer. The objective is not to generate generic applications following the lowest-common-denominator approach, but to follow the particular guidelines specified for each target device. We present an example application modeled in LIZARD, generating different UIs for Windows Phone and two types of Android devices (smartphones and tablets).

《化学科学与工程前沿（英文）》 2016年第10卷第2期页码 294-300 doi: 10.1007/s11705-016-1564-4

摘要： Two-dimensional self-assembly of melem at pH-controlled aqueous solution-Au(111) interfaces has been investigated by electrochemical scanning tunneling microscopy. In the solutions with pH>p of melem, two ordered self-assembled structures (honeycomb and close-packed structures) and one disordered fibrillar structure were observed as a function of the surface coverage of melem controlled by the electrode potential. In contrast, in the acidic solution with pH

Gas marbles: ultra-long-lasting and ultra-robust bubbles formed by particle stabilization

《化学科学与工程前沿（英文）》页码 1681-1687 doi: 10.1007/s11705-022-2180-0

摘要： Bubbles and foams are ubiquitous in daily life and industrial processes. Studying their dynamic behaviors is of key importance for foam manufacturing processes in food packaging, cosmetics and pharmaceuticals. Bare bubbles are inherently fragile and transient; enhancing their robustness and shelf lives is an ongoing challenge. Their rupture can be attributed to liquid evaporation, thin film drainage and the nuclei of environmental dust. Inspired by particle-stabilized interfaces in Pickering emulsions, armored bubbles and liquid marble, bubbles are protected by an enclosed particle-entrapping liquid thin film, and the resultant soft object is termed gas marble. The gas marble exhibits mechanical strength orders of magnitude higher than that of soap bubbles when subjected to overpressure and underpressure, owing to the compact particle monolayer straddling the surface liquid film. By using a water-absorbent glycerol solution, the resulting gas marble can persist for 465 d in normal atmospheric settings. This particle-stabilizing approach not only has practical implications for foam manufacturing processes but also can inspire the new design and fabrication of functional biomaterials and biomedicines.

Effects of preparation methods on the activity of CuO/CeO

Huanhuan Shang, Xiaoman Zhang, Jing Xu, Yifan Han

《化学科学与工程前沿（英文）》 2017年第11卷第4期页码 603-612 doi: 10.1007/s11705-017-1661-z

摘要： CO oxidation has been investigated on three CuO/CeO catalysts prepared by impregnation, co-precipitation and mechanical mixing. The origin of active sites was explored by the multiple techniques. The catalyst prepared by impregnation has more highly dispersed CuO and stronger interactions between CuO and CeO to promote the reduction of CuO to Cu species at the Cu-Ce interface, leading to its highest catalytic activity. For the catalyst prepared by co-precipitation, solid solution structures observed in Raman spectra suppress the formation of the Cu-Ce interface, where the adsorbed CO will react with active lattice oxygen to form CO , and thus it displays a lower catalytic performance. No Cu-Ce interface exists in the catalyst prepared by the mechanical mixing method due to the separate phases of CuO and CeO , resulting in its lowest activity among the three catalysts.

Influence of surface modified mixed metal oxide nanoparticles on the electrochemical and mechanical properties of polyurethane matrix

《化学科学与工程前沿（英文）》 2023年第17卷第1期页码 1-14 doi: 10.1007/s11705-022-2176-9

摘要： Newly synthesized functional nanoparticles, 3-amino-1,2,4-triazole (ATA)/SiO₂–TiO₂ were introduced to the polyurethane (PU) matrix. Electrochemical techniques were used to investigate the barrier properties of the synthesized PU–ATA/SiO₂–TiO₂ nanocomposite coated steel specimen. In natural seawater, electrochemical impedance spectroscopy experiments indicated outstanding protective behaviour for the PU–ATA/SiO₂–TiO₂ coated steel. The coating resistance (R_coat) of PU–ATA/SiO₂–TiO₂ was determined to be 2956.90 kΩ·cm^–2. The R_coat of the PU–ATA/SiO₂–TiO₂ nanocomposite coating was found to be over 50% higher than the PU coating. The current measured along the scratched surface of the PU–ATA/SiO₂–TiO₂ coating was found to be very low (1.65 nA). The enhanced ATA/SiO₂–TiO₂ nanoparticles inhibited the entry of electrolytes into the coating interface, as revealed by scanning electron microscopy/energy dispersive X-ray spectroscopy and X-ray diffraction analysis of the degradation products. Water contact angle testing validated the hydrophobic nature of the PU–ATA/SiO₂–TiO₂ coating (θ = 115.4°). When the concentration of ATA/SiO₂−TiO₂ nanoparticles was 2 wt %, dynamic mechanical analysis revealed better mechanical properties. Therefore, the newly synthesised PU–ATA/SiO₂–TiO₂ nanocomposite provided excellent barrier and mechanical properties due to the addition of ATA/SiO₂–TiO₂ nanoparticles to the polyurethane, which inhibited material degradation and aided in the prolongation of the coated steel’s life.

Recent development and application of thin-film thermoelectric cooler

Yuedong Yu, Wei Zhu, Xixia Kong, Yaling Wang, Pengcheng Zhu, Yuan Deng

《化学科学与工程前沿（英文）》 2020年第14卷第4期页码 492-503 doi: 10.1007/s11705-019-1829-9

摘要： Recently, the performance and fabrication of thin-film thermoelectric materials have been largely enhanced. Based on this enhancement, the thin-film thermoelectric cooler (TEC) is becoming a research hot topic, due to its high cooling flux and microchip level size. To fulfill a thin-film TEC, interfacial problems are unavoidable, as they may largely reduce the properties of a thin-film TEC. Moreover, the architecture of a thin-film TEC should also be properly designed. In this review, we introduced the enhancement of thermoelectric properties of (Bi,Sb) (Te,Se) solid solution materials by chemical vapor deposition, physical vapor deposition and electrodeposition. Then, the interfacial problems, including contact resistance, interfacial diffusion and thermal contact resistance, were discussed. Furthermore, the design, fabrication, as well as the performance of thin-film TECs were summarized.

氯化水与地表水导致的膜污染对比解析——生物污染特性和微生物探究 Article

张莉, 徐磊, Nigel Graham, 俞文正

《工程（英文）》 2022年第15卷第8期页码 154-164 doi: 10.1016/j.eng.2021.03.016

摘要：

氯在城市水处理过程中通常用于灭活病原体和预防水媒疾病，但是目前尚不清楚其作为一种预处理技术是否能够有效地缓解超滤过程中产生的膜污染。在本研究中，我们探究了自来水在重力驱动膜过滤系统中对生物膜的形成及生物污染的影响。同时，未处理的地表水（湖水）所形成的生物膜/生物污染也进行了对比研究。研究表明，自来水过滤系统产生了比湖水更严重的膜污染，而且多糖和eDNA的含量更高。其生物膜形态致密，但是湖水形成的生物膜是多孔、类似蜘蛛网状的结构，猜测可能与生物膜中的细菌有关。16S rRNA测序结果表明，Xanthobacter在自来水形成的生物膜中占据优势地位。此外，研究发现膜的亲、疏水性对膜污染特性和微生物群落的影响较小。本研究揭示了耐氯细菌在膜污染形成中的重要作用，更深入地认识了膜污染，可为寻求有效的膜污染控制方法提供帮助。
