4A novel pathway for the preparation of Mg metal from magnesia显示文摘High-purity anhydrous magnesium chloride was prepared from magnesia and ammonium chloride.The chlorination process was analyzed and then the critical stages affecting the purity of anhydrous magnesium chloride were pinpointed.The effect of sample dimension on the above critical stages was investigated respectively.The purity guarantee mechanism of anhydrous magnesium chloride was proposed.After that,magnesium metal was obtained via electrolyzing the anhydrous magnesium chloride-containing molten salt.The new process for the continuous production of magnesium metal from magnesia was proposed and discussed.The incomplete chlorination reaction and the hydrolysis of anhydrous magnesium chloride are the two critical stages affecting the purity of the anhydrous magnesium chloride.The dimension of the sample can influence reaction process and reaction mechanism,and thus the problems of incomplete chlorination reaction and hydrolysis can be solved together.The magnesia content in anhydrous magnesium chloride was below 0.1 wt.%when the ratio of height to diameter of the sample was over 2.43.The content of impurities in the magnesium metal obtained met the specifications of the product Mg9980.The current efficiency was(94.7±1.8)%and the electricity consumption was(9107±97)kW h/t.Zhimin Zhang Xuchen Lu Yan Yan 2022Journal of Magnesium and Alloys2022,10,10:1

7Preparation characterization of LaNiO3 A/F ratio-sensitive thin film by sol-gel process based on amorphous citrate precursors显示文摘Lu Xuchen Xu Tingxian Dong Xianghong 2000Sensors and Actuators B2000,67,12:1
8Synthesis of SAPO-34 using metakaolin in the presence of β-cyclodextrin显示文摘SAPO-34 molecular sieves were synthesized by the addition of β-cyclodextrin(β-CD) as crystal growth inhibitor using metakaolin as silicon and aluminum sources. Properties of the obtained samples were characterized by XRD,SEM,N2adsorption–desorption,FTIR,XRF,EDX,NH293-TPD andSi MAS NMR. When β-CD was added,crystal size of the SAPO-34 crystals decreased. Variation of Si content from the crystal center to surface decreased while total Si content hardly changed.29 Si MAS NMR results showed that β-CD contributed to better Si dispersion and decreased the size of Si(4Si) patches. Moreover,the MTO(methanol-to-olefin) process was conducted to investigate the influence of β-CD on catalytic performance. The synthesized sample with molar ratio of β-CD/Al2O3 equaling 0.055 remained active for 610 min while the sample synthesized without β-CD for only 280 min,which indicates that the lifetime of catalyst synthesized with β-CD is greatly prolonged.Chen Zhang Xuchen Lu Tizhuang Wang 2015Journal of Energy Chemistry2015,24,4:1

10PREPARATION AND SEPARATING PROPERTIES OF MoS_2/γ-Al_2O_3 CERAMIC COMPOSITE MEMBRANE FOR H_2S-H_2 MIXTURE显示文摘MoS2/γ-Al2O3 ceramic composite membrane is successfully synthesized by the sol-gel method based on the inorganic salt route. The aluminum hydrate sol derived from the inorganic salt Al(NO3)3, whose transparence and viscosity are 97% and 1.2 × 10-3 Pa. s, respectively, can be formed through adjusting the ratio of the peptizing agent H+ to Al3+ to 0.3. The aluminum hydrate gel at 110℃ is amorphous in structure and is heat-treated in air at 800℃ to form γ-Al2O3. The precursor derived from the mixture solution of ammonium molybdate, thioacetamide and a reducing agent, can be transformed into crystal MoS2 under reducing condition at 800℃. MoS2/γ-Al2O3 composite membrane is an organic whole and bps no gradation from MoS2 layer to γ-Al2O3 Iayer. The separation factor a H2/H2S through the MoS2/γ-Al2O3 composite membrane increase with rising temperature and a H2/H2S at 600℃ is 4.45 higher than the theoretical separation factor produced by the ideal Knudsen diffusion.Lu Xuchen, Li Youchu, Huang Changxiong and Qing Xiangdong (Institute of Chemical Metallurgy, Chinese Academy of Sciences, P.O Box 353 , Beijing 100080, China) 2000化工学报2000,51,S1:0
11CACA Guidelines for Holistic Integrative Management of Breast Cancer显示文摘Purpose:Breast cancer is now the most common malignant tumor worldwide.About one-fourth of female cancer patients all over the world sufer from breast cancer.And about one in six female cancer deaths worldwide is caused by breast cancer.In terms of absolute numbers of cases and deaths,China ranks frst in the world.The CACA Guidelines for Holistic Integrative Management of Breast Cancer were edited to help improve the diagnosis and comprehensive treatment in China.Methods:The Grading of Recommendations Assessment,Development and Evaluation(GRADE)was used to classify evidence and consensus.Results:The CACA Guidelines for Holistic Integrative Management of Breast Cancer include the epidemiology of breast cancer,breast cancer screening,breast cancer diagnosis,early breast cancer treatment,advanced breast cancer treatment,follow-up,rehabilitation,and traditional Chinese medicine treatment of breast cancer patients.Conclusion:We to standardize the diagnosis and treatment of breast cancer in China through the formulation of the CACA Guidelines.Jiong Wu Daiming Fan Zhimin Shao Binghe Xu Guosheng Ren Zefei Jiang Yongsheng Wang Feng Jin Jin Zhang Qingyuan Zhang Fei Ma Jinli Ma Zhonghua Wang Shusen Wang Xiaojia Wang Shu Wang Haibo Wang Tao Wang Xiang Wang Jing Wang Jia Wang Biyun Wang Li Fu Hongyuan Li Yehui Shi Lu Gan Yunjiang Liu Jian Liu Zhenzhen Liu Qiang Liu Qiang Sun Wenwu Cheng Keda Yu Zhongsheng Tong Xinhong Wu Chuangui Song Jianguo Zhang Jian Zhang Junjie Li Bin Li Man Li Huiping Li Wentao Yang Hongjian Yang Benlong Yang Hong Bu Juping Shen Zhenzhou Shen Yiding Chen Ceshi Chen Da Pang Zhimin Fan Ying Zheng Xiaoli Yu Guangyu Liu Xichun Hu Yiqun Ling Jinhai Tang Yongmei Yin Cuizhi Geng Peng Yuan Yajia Gu Cai Chang Xuchen Cao Yuan Sheng Yuanxi Huang Jian Huang Weijun Peng Xiaohua Zeng Yuntao Xie Ning Liao Committee of Breast Cancer Society,Chinese Anti-Cancer Association 2022Holistic Integrative Oncology2022,1,1:0
12Assessment of causal effects of physical activity on neurodegenerative diseases:A Mendelian randomization study显示文摘Background:Physical activity has been hypothesized to play a protective role in neurodegenerative diseases.However,effect estimates previously derived from observational studies were prone to confounding or reverse causation.Methods:We performed a two-sample Mendelian randomization(MR)analysis to explore the causal association of accelerometer-measured physical activity with 3 common neurodegenerative diseases:Alzheimer’s disease(AD),Parkinson’s disease(PD),and amyotrophic lateral sclerosis(ALS).We selected genetic instrumental variants reaching genome-wide significance(p<5×10^(-8))from 2 largest meta-analyses of about 91,100 UK Biobank participants.Summary statistics for AD,PD,and ALS were retrieved from the up-to-date studies in European ancestry led by the international consortia.The random-effect,inverse-variance weighted MR was employed as the primary method,while MR pleiotropy residual sum and outlier(MR-PRESSO),weighted median,and MR-Egger were implemented as sensitivity tests.All statistical analyses were performed using the R programming language(Version 3.6.1;R Foundation for Statistical Computing,Vienna,Austria).Results:Primary MR analysis and replication analysis utilized 5 and 8 instrumental variables,which explained 0.2%and 0.4%variance in physical activity,respectively.In each set,one variant at 17q21 was significantly associated with PD,and MR sensitivity analyses indicated them it as an outlier and source of heterogeneity and pleiotropy.Primary results with the removal of outlier variants suggested odds ratios(ORs)of neurodegenerative diseases per unit increase in objectively measured physical activity were 1.52 for AD(95%confidence interval(95%CI):0.88-2.63,p=0.13)and 3.35 for PD(95%CI:1.32-8.48,p=0.01),while inconsistent results were shown in the replication set for AD(OR=1.06,95%CI:1.01-1.12,p=0.02)and PD(OR=0.99,95%CI:0.88-0.12,p=0.97).Similarly,the beneficial effect of physical activity on ALS(OR=0.51,95%CI:0.29-0.91,p=0.02)was not confirmed in the replication analysis(OR=0.96,95%CI:0.91-1.02,p=0.22).Conclusion:Genetically predicted physical activity was not robustly associated with risk of neurodegenerative disorders.Triangulating evidence across other studies is necessary in order to elucidate whether enhancing physical activity is an effective approach in preventing the onset of AD,PD,or ALS.Peng-Fei Wu Hui Lu Xiaoting Zhou Xuchen Liang Ruizhuo Li Wan Zhang Danyang Li Kun Xia 2021Journal of Sport and Health Science2021,10,4:0
