City and Country: a Narrative Analysis of Partnership in Mediation

SHS Web of Conferences (2022)

Jiamei Yu

In recent years, short video has been popular with the public, and its content has been constantly enriched in the development process to meet the needs of different users. As an important branch of short video field, life short video has been continuously sought after by users[5]. In today’s era of advocating equality between men and women, the relationship between men and women is also the topic most discussed by people with the continuous development of society. In short life videos, one of the main scenes of the relationship between men and women is the daily relationship between partners. In order to analyze the difference of relationship between urban and rural areas, this article adopted literature research and text analysis method to explore and compare the urban and rural lifestyle between partners in a short video in the type of love, love attitude, Partner relationship and get along with atmosphere on the different way of narrative, and summarizes the media partnership narrative differences between urban and rural table to concentrated reflection. It is found that there are indeed differences between urban and rural areas in the above four aspects. In urban media, couples’ life tends to be “happy and happy binary relationship life” while in rural areas, couples’ life tends to be “harmonious and multiple relationship life” and so on. However, the story presented in the media is different from the real life, so the last part of this paper also makes a correct guide to the media partner relationship.

How Impurities Affect CO₂ Capture in Metal–Organic Frameworks Modified with Different Functional Groups

ACS Sustainable Chemistry & Engineering (2014)

Jiamei Yu Perla B. Balbuena

The introduction of functional groups in metal–organic frameworks (MOFs) has been found to be a successful strategy for improving CO2 selective separation from N2. However, little is known regarding how impurities such as H2O and SO2 may interfere with CO2 capture as a function of the properties of the functional groups in MOF adsorbent materials. Here, the effects of water and SO2 on CO2 capture in UiO-66(Zr) MOFs are systematically explored. The basic structure of UiO-66(Zr) is modified in each case with −NH2, −OH, or −Br functional groups, and CO2 capture is investigated using molecular simulations. It is found that for UiO-66(Zr) with −NH2 and −OH groups, due to strong interactions between water and the framework, the presence of water lowers CO2 adsorption significantly. In contrast, due to the water-phobic effects of −Br, and subsequent low binding strength between water and UiO-66-Br, water has much smaller effect on CO2 capture in this MOF. Regarding SO2 effects, the presence of SO2 in the mixtures decreases water adsorption in both UiO-66-NH2 and UiO-66-Br. The lower water adsorption for the CO2/N2/H2O/SO2 mixture in UiO-66-NH2 can be mainly attributed to the strong binding strength between SO2 and the framework. On the other hand, in UiO-66-Br, the lower water adsorption is mainly ascribed to the stronger affinity of water toward SO2 rather than to the framework. The lower water adsorption makes more sites available for CO2 adsorption, and therefore, the CO2 adsorptions are enhanced accordingly in UiO-66-Br.

Building multiple adsorption sites in porous polymer networks for carbon capture applications

Energy & Environmental Science (2013)

Weigang Lu Wolfgang M. Verdegaal Jiamei Yu Perla B. Balbuena Hae‐Kwon Jeong

IAST calculations reveal that sulfonate ammonium salt grafting renders porous polymer networks (PPN-6-SO3NH4) with exceptionally high adsorption selectivity for CO2 over N2 and CO2 over CH4. Breakthrough experiments confirm the high CO2 adsorption capacity (1.7 mmol g−1, 75 mg g−1) by feeding 15% CO2 balanced with N2 at 295 K and 1 bar.

Direct Access to Medium‐Chain α,ω‐Dicarboxylic Acids by Using a Baeyer–Villiger Monooxygenase of Abnormal Regioselectivity

ChemBioChem (2018)

Jiamei Yu Yuanyang Liu Yu‐Cong Zheng Hao Li Xiaoyan Zhang

Baeyer-Villiger monooxygenases (BVMOs) are versatile biocatalysts in organic synthesis that can generate esters or lactones by inserting a single oxygen atom adjacent to a carbonyl moiety. The regioselectivity of BVMOs is essential in determining the ratio of two regioisomers for converting asymmetric ketones. Herein, we report a novel BVMO from Pseudomonas aeruginosa (PaBVMO); this has been exploited for the direct synthesis of medium-chain α,ω-dicarboxylic acids through a Baeyer-Villiger oxidation-hydrolysis cascade. PaBVMO displayed the highest abnormal regioselectivity toward a variety of long-chain aliphatic keto acids (C16 -C20 ) to date, affording dicarboxylic monoesters with a ratio of up to 95 %. Upon chemical hydrolysis, α,ω-dicarboxylic acids and fatty alcohols are readily obtained without further treatment; this significantly reduces the synthetic steps of α,ω-dicarboxylic acids from renewable oils and fats.

Effective Removal of Clenbuterol and Ractopamine from Water with a Stable Al(III)-Based Metal–Organic Framework

Inorganic Chemistry (2021)

Jie Lv Qiang Chen Jing-Hao Liu Haosen Yang Peilong Wang

Clenbuterol (CLE) and ractopamine (RAC) are two kinds of typical β2-adrenergic agonists which pose a serious threat to the health of human beings. In this work, 10 kinds of metal–organic frameworks (MOFs) with high stability and various pore features are screened to assess adsorption performance for CLE and RAC. An Al(III)-MOF (BUT-19) with abundant ethyl groups exhibits exceptional performance in removing CLE and RAC from water. The maximum adsorption capacity for CLE and RAC are up to 294.1 and 366.3 mg/g under the optimum adsorption conditions, respectively. Meanwhile, the adsorption mechanism effects of pH, temperature, and coexisted ions are investigated systematically. It is found that the MOF pore size and weak hydrogen-bond interactions between CLE/RAC molecules and the MOF are the main causes leading to the extraordinary adsorption. This study provides a new idea for the purposeful design and synthesis of MOFs for removing environmental pollutants and sheds light on the depuration of contaminated water.

Simultaneous Trapping of C₂H₂ and C₂H₆ from a Ternary Mixture of C₂H₂/C₂H₄/C₂H₆ in a Robust Metal–Organic Framework for the Purification of C₂H₄

Angewandte Chemie (2018)

Hongguo Hao Yunfeng Zhao Di‐Ming Chen Jiamei Yu Kui Tan

Abstract The removal of C 2 H 2 and C 2 H 6 from C 2 H 4 streams is of great significance for feedstock purification to produce polyethylene and other commodity chemicals but the simultaneous adsorption of C 2 H 6 and C 2 H 2 over C 2 H 4 from a ternary mixture has never been realized. Herein, a robust metal–organic framework, TJT‐100, was designed and synthesized, which demonstrates remarkably selective adsorption of C 2 H 2 and C 2 H 6 over C 2 H 4 . Breakthrough experiments show that TJT‐100 can be used as an adsorbent for high‐performance purification of C 2 H 4 from a ternary mixture of C 2 H 2 /C 2 H 4 /C 2 H 6 (0.5:99:0.5) to afford a C 2 H 4 purity greater than 99.997 %, beyond that required for ethylene polymerization. Computational studies reveal that the uncoordinated carboxylate oxygen atoms and coordinated water molecules pointing towards the pore can trap C 2 H 2 and C 2 H 6 through the formation of multiple C−H⋅⋅⋅O electrostatic interactions, while the corresponding C 2 H 4 –framework interaction is unfavorable.

Abstract BACKGROUND Setting effects are different for each fish species tested. There is no published literature on the response of Amur sturgeon ( Acipenser schrenckii ) to increased setting times. This study investigated the effects of high‐temperature setting (40 °C) for different durations on the gel properties of A. schrenckii surimi. As A. schrenckii is a new surimi material, it is also necessary to conduct a sensory evaluation and to report the surimi yields. RESULTS Increasing setting durations (0.5–1.5 h) significantly improved the gel properties. The best results in terms of molecular forces, gel strength, texture profile analysis (TPA), water holding capacity (WHC), and whiteness were obtained by the gels with setting durations of 1 and 1.5 h. The protein degradation detected as a result of extended setting durations (>2 h) significantly decreased the gel properties. The most inferior gel properties were shown by the gel with setting for 3 h. Protein degradation also resulted in higher cooking loss and poor microstructures. The sensory evaluation indicated that A. schrenckii surimi was generally accepted by the panelists in terms of color, texture, and aroma. The surimi yield obtained in this study was 32.4%, which was similar to commercial surimi and higher than several surimi yields in recent studies. CONCLUSION Setting durations from 0.5 to 1.5 h can be implemented to improve the properties of A. schrenckii surimi. Extended durations (>2 h) must be avoided. Overall, this work provided some necessary information about setting response, gel properties, sensory evaluation, and surimi yield in A. schrenckii , which will be useful for further studies. © 2020 Society of Chemical Industry
