| 1 | The effect of nanohybrid materials on the pour-point and viscosity depressing of waxy crude oil显示文摘The pipeline transportation of waxy crude oil is a problem both at home and abroad.In this paper,a novel nanohybrid pour-point depressant (PPD) was used to decrease the pour point and viscosity of waxy crude oil.The pour point and apparent viscosity of waxy crude oil was decreased significantly upon addition of the nanohybrid PPD,and the long-term stability of the nanohybrid PPD was superior to that of a conventional ethylene-vinyl acetate copolymer PPD.Polarized optical microscopy and X-ray diffraction were used to study the effect of the nanohybrid PPD on the crystallization of crude oil.Addition of the nanohybrid PPD reduced the amount of wax crystals,prevented their aggregation,and reduced the temperature at which the crude oil started to crystallize.The significant effect of this nanohybrid PPD on the pour point and viscosity depressing of crude oil is of great importance for facilitating the safe,efficient and energy-minimized transportation of waxy crude oil. | WANG Feng ZHANG DongMin DING YanFen ZHANG LiXin YANG MingShu JIANG BaoLiang ZHANG ShiMin AI MuYang LIU GuangWen ZHI ShuJie HUO LianFeng OUYANG Xin LI Li | 2011 | Chinese Science Bulletin2011，56，1： | 9 |
| 2 | Decomposition process of zircon sand concentrate with CaO-NaOH显示文摘The decomposition process for zircon sand concentrate using mixed base of sodium hydroxide partly replaced by calcium oxide was inrestigated.It is found that the decomposition rate of zircon gradually increased with the increase of the reaction temperature and time.The decomposition rate is over 97% with the conditions that CaO/zircon molar ratio is 0.25 ~ 0.75 at 800 ℃ for 1 h.Whereas the decomposition rate decreased when the molar ratio was more than 0.75.Also,thermogravimetry-differential thermal analysis(TG-DTA) and X-ray diffraction(XRD) were used to study the reaction mechanism of zircon decomposition process with CaO-NaOH.The results showed that Na_2O,which was generated by the reaction of CaO and Na_4SiO_4,increased the decomposition rate of zircon owing to its spread to the surface of zircon and played a role in decomposition process. | Zhang, Jiandong Wang, Lijun Jiang, Dongmin | 2012 | Rare Metals2012，31，4： | 3 |
| 3 | Ammonia leaching mechanism and kinetics of LiCoO_(2) material from spent lithium-ion batteries显示文摘In this paper,the ammonia leaching process and high-energy ball milling method were adapted to recover spent LiCoO_(2) material.The ammonia reduction leaching mechanism of LiCoO_(2) material in the ammonia-sodium sulfite-ammonium chloride system was elucidated.Compared with untreated LiCoO_(2) material,the leaching equilibrium time of LiCoO_(2) after ball-milled for 5 h was reduced from 48 h to 4 h,and the leaching efficiency of lithium and cobalt was improved from 69.86%and 70.80%to 89.86%and98.22%,respectively.Importantly,the apparent activation energy and leaching kinetic equation of the reaction was calculated by the shrinking core reaction model,indicating that the reaction was controlled by the chemical reaction. | Dongmin Li Bao Zhang Xing Ou Jiafeng Zhang Kui Meng Guanjun Ji Pengfei Li Jianhui Xu | 2021 | Chinese Chemical Letters2021，32，7： | 2 |

| 10 | Electrochemically prepared coniferous leaf-like nickel black membrane for desalination by solar-thermal energy conversion显示文摘The structures of the solar-thermal membranes always influence the performance of light absorption and salt resistance in desalination.Inspired by the hierarchical structure of the coniferous leaves with excellent sunlight absorption in frigid regions,a coniferous leaf-like nickel black(L-Ni)membrane for desalination by solar-thermal energy conversion was prepared through electroplating method under a constant voltage.The light trapping effect of coniferous leaf-like structure led to the light absorption enhanced to 92%,the evaporation rate improved to 1.38 kg·m^(-2)·h^(-1),and the solar-vapor conversion efficiency of L-Ni membrane reaching up to 89.75%under 1 sun irradiation.The stability of the membrane was still excellent after 20 cycles desalination because the coniferous leaf-like structure could enhance the hydrophobicity(water contact angle:152°)of the L-Ni membrane,and it was beneficial to salt resistance.The promising performance of L-Ni membrane with coniferous leaf-like structure provides a possibility to replace the noble metal solar-thermal conversion materials. | Dongmin Yue Bingbing Li De Sun Hao Zhang Meiling Liu Jingtong Yu | 2023 | Nano Research2023，16，7： | 1 |

| 17 | Association Between Physical Activity and Physical Fitness Among Adults Aged 40 to 79 Years—Beijing,China,2020–2021显示文摘Summary What is already known about this topic?Physical fitness is well documented to be associated with physical activity among adults in the United States.In China,research on this association places a heavier emphasis on the populations of children and adolescents.What is added by this report?Physical fitness was shown to be positively associated with physical activity among adults aged 40 to 79 years in China.In populations with lower levels of physical fitness,this association was stronger.The coefficients of the log-transformed metabolic equivalent value of physical activity(logPA)in quantile regression models at the 25th,50th,75th,and 90th percentile of the physical fitness indicators were 1.14,1.04,0.89,and 0.84,respectively. | Xiaojin Yan Heming Pei Yalu Zhang Ning Kang Gong Chen Dongmin Wang | 2022 | China CDC weekly2022，4，42： | 0 |
| 18 | Functional outcomes of Tai Chi exercise prescription in women with knee osteoarthritis显示文摘Knee Osteoarthritis(KOA)is the most common type of knee joint injury and also a risk factor for multiple health consequences and is prevalent among older women.The updated clinical guidelines for KOA treatment by the American Rheumatism Association recommend Tai Chi exercise.However,a literature review outlined limitations in Tai Chi intervention implementations.This study aimed to address some of the gaps.This study selected thirty female patients to participate in Tai Chi exercises and undergo relevant tests.The subjects were randomly assigned to Tai Chi or education groups.Independent sample t-tests were conducted to compare the difference in health indicators between the two groups after the intervention.The difference-in-differences(DID)regression was performed to assess the difference in the health outcomes between the two groups at baseline and follow-up and the difference in the differences.After the completion of the intervention,the Tai Chi group reported significantly improved KOA symptoms,physical fitness,and health status indicators than the control group.Specifically,the group differences were significantly larger at the baseline than at the follow-up.Our findings provide compelling evidence of the effects of the innovative Tai Chi exercise prescription specifically designed for KOA patients.The empirical evidence on its effectiveness in alleviating KOA symptoms and improving the overall health of middle-aged and elderly women with KOA suggested that Tai Chi intervention exercise has huge prospects for integration in KOA rehabilitation therapy. | Ning Kang Yi Wang Gong Chen Chao Guo Zhanjia Zhang Donghui Mei Nancy Morrow-Howell Dongmin Wang | 2022 | Sports Medicine and Health Science2022，4，4： | 0 |
| 19 | Regioselectivity of Pd-catalyzed o-carboranearylation: a theoretical view显示文摘The mechanism and the regioselectivity of Pd-catalyzed B(4)–H arylation and B(4,5)–H diarylation foro-carborane with bidentate directing groups were investigated. The complete catalytic cycle involves Pdmediated concerted metalation–deprotonation, oxidative addition, counterion exchange, and reductiveelimination, where counterion exchange is critical. The reductive elimination is the rate- and regioselectivity-determining step for the whole catalytic cycle. B(3)-Arylation is unfavorable because the stericrepulsion between the substituent group on C(2) and the metal moiety would lead to significant distortionof o-carborane and would result in a higher activation energy for reductive elimination. The distortion ofo-carborane can be clearly observed from the change of its aromaticity in the corresponding transitionstates by the calculation of nucleus-independent chemical shifts. Moreover, counterion exchange withcarboxylate before reductive elimination significantly increases the positive charge of palladium, whichleads to a lower activation free energy for the sequential step. | Jiying Liu Dongmin Fu Zitong Chen Tiantian Li Ling-Bo Qu Shi-Jun Li Wenjing Zhang Yu Lan | 2022 | Organic Chemistry Frontiers2022，9，6： | 0 |
| 20 | Research on Influence Factors of Pig Farmers' Ecological Farming Behavior: Based on the TPB and SEM显示文摘China's extensive development model of pig industry gives rise to serious resource and environment bottleneck restriction,it is urgent to transform the existing development model into ecological farming model. In this process,farmers' behavior will play a key role. On the basis of summarizing development connotation and characteristics of ecological agriculture,using survey data of 323 pig farmers in 6 provinces,based on the Theory of Planned Behavior( TPB) it introduced individual characteristics and external environment constraint variables,and made an empirical analysis on factors influencing intention and behavior of pig farmers' ecological farming using the Structural Equation Model( SEM). Results indicate:( i) ecological farming intention of pig farmers has the largest direct effect on their ecological farming behavior;( ii)ecological farming cognition of pig farmers has significant positive effect on their ecological farming behavior;( iii) external environment has the largest indirect effect on their ecological farming behavior,followed by the overall effect,and external environment has significant positive effect on ecological farming attitude and cognition of pig farmers;( iv) individual characteristics( educational level and income level) of pig farmers influence ecological farming behavior of pig farmers through their ecological farming attitude and intention,but the degree of influence is limited. | Chengying HAN Zhenhong QI Dongmin ZHANG Xinrui LI | 2016 | Asian Agricultural Research2016，8，2： | 0 |
