| 1 | New Evidence for Genesis of the Zoige Carbonate-Siliceous-Pelitic Rock Type Uranium Deposit in Southern Qinling:Discovery and Significance of the 64 Ma Intrusions显示文摘在 Zoige 区域的 carbonaceous-siliceous-argillitic 岩石类型铀存款位于西藏的高原的东北边缘,并且由于它的规模,高等级和丰富的联系矿石获得了许多地质学家和矿石存款专家的许多注意。因为恼人的岩石,在矿化作用之间的关系和 magmatic 活动的不够的可靠标明日期仍然是未知的。为了学习这个关键科学问题和 Zoige 铀矿石的形成矿石的过程,回答, magmatic 岩石标明日期的 LA-ICP-MS 锆石 U-Pb 被获得:为 granite-prophyry 的 64.08 ±0.59 妈和为粗玄岩的 ∼200 妈。从 Zoige 铀矿石地标明日期沥青铀矿的结果的 U-Pb 主要被专注于 ∼90 妈和 ∼60 妈。根据 LA-ICP-MS U-Pb 锆石标明日期,为粗玄岩的年龄,斑岩花岗石和 granodiorite 是 200 妈, 64.08 妈近似并且 226.5-200.88 妈分别地。这显示矿化作用与中介酸的岩浆的活动有靠近的关系。花岗石斑岩的年龄与标明日期以前的研究完成的结果的那些沥青铀矿 U-Pb 一致,它在以后的 Yanshanian 期间反映 magmatic 和形成矿石的事件。从以前的研究基于数据, Zoige 铀矿石领域里的矿石身体能被划分成二个范畴:有 polymetal 矿化作用的单个铀类型和铀打字。,在迟了的白垩纪(大约 90 妈) 形成的前者后者,仔细与花岗石斑岩有关,在早 Paleogene (大约 60 妈) 形成了。并且除了矿石形成元素的铀,后者经常与 polymetallic 元素被联系例如铝,镍,锌,等等。 | SONG Hao ZHANG Chengjiang NI Shijun XU Zhengqi HUANG Changhua | 2014 | Acta Geologica Sinica(English Edition)2014，88，6： | 4 |
| 2 | Investigation of the effect of filling level on the wear and vibration of a SAG mill by DEM显示文摘Semi-autogenous grinding(SAG)mill is widely used in the grinding process of coal and ores because of its strong applicability,large capacity and low consumption of grinding media.Therefore,the research of SAG mill is still of great important practical significance.Among those parameters of the SAG mill,the flling level is very important for it is not only directly related to the processing capacity of the mill,but also affects the operation cost and stability of mill.In this paper,combined with shear impact energy model(SIEM)and discrete element method(DEM),the particle collision energy spectrum was applied to analyze the influence of ore flling level and media flling level on the power draw of the mill,the impact energy on ore,and the wear of liner and media in a slice of an industrial SAG mill.It was found that increasing the ore flling level would increase energy consumption and reduce the energy efficiency and the wear of liner and grinding media.Furthermore,the vibration of mill was explored from the collision energy on liner.The results showed that the low frequency but high energy ollision between grinding media and liner was the main reason for liner wear and mill vibration. | Changhua Xie Yuan Zhao Tao Song Yongzhi Zhao | 2022 | Particuology2022，20，4： | 2 |

| 6 | Production of 5-Hydroxymethylfurfural from Fructose in Ionic Liquid Efficiently Catalyzed by Cr(III)-Al_(2)O_(3)Catalyst显示文摘A series of metal-Al_(2)O_(3)catalysts were prepared simply by the conventional impregnation with Al_(2)O_(3)and metal chlorides,which were applied to the dehydration of fructose to 5-hydroxymethylfurfural(HMF).An agreeable HMF yield of 93.1%was achieved from fructose at mild conditions(100℃and 40 min)when employing Cr(III)-Al_(2)O_(3)as catalyst in 1-butyl-3-methylimidazolium chloride([Bmim]Cl).The Cr(III)-Al_(2)O_(3)catalyst was characterized via XRD,DRS and Raman spectra and the results clarified the interaction between the Cr(III)and the alumina support.Meanwhile,the reaction solvents([Bmim]Cl)collected after 1st reaction run and 5th reaction run were analyzed by ICP-OES and LC-ITMS and the results confirmed that no Cr(III)ion was dropped off from the alumina support dur-ing the fructose dehydration.Notably,Cr(III)-Al_(2)O_(3)catalyst had an excellent catalytic performance for glucose and sucrose and the HMF yields were reached to 73.7%and 84.1%at 120℃for 60 min,respectively.Furthermore,the system of Cr(III)-Al_(2)O_(3)and[Bmim]Cl exhibited a constant stability and activity at 100℃for 40 min and a fa-vorable HMF yield was maintained after ten recycles. | Changhua Song Hui Liu Yuan Li Shuai Ge Hongwei Wang Wenshuai Zhu Yonghui Chang Changri Han Huaming Li | 2014 | Chinese Journal of Chemistry2014，32，5： | 1 |

| 10 | A robust ethane-trapping metal-organic framework for efficient purification of ethylene显示文摘Owing to the similar physicochemical properties between ethane(C_(2)H_(6))and ethylene(C_(2)H_(4)),obtaining polymerization-grade C_(2)H_(4)(≥99.95%pure)is still a tricky problem in the petrochemical industry.Here,we report a robust scandium-based metalorganic framework(Sc BPDC),which is connected by oxygen-rich phenyl ligand with exceptionally high thermal stability(up to873 K)and capacity of C_(2)H_(6)(4.94 mmol/g at 100 k Pa and 283 K),exhibiting superior separation performance of C_(2)H_(6)/C_(2)H_(4) mixture(the IAST selectivity is up to 1.7 at 283 K).Importantly,Sc BPDC can produce 8.96 L/kg C_(2)H_(4) with≥99.99%purity while the C_(2)H_(4)/C_(2)H_(6)(50:50,v/v)as the mixture injection and the low isosteric heat of Sc BPDC(16.4 k J/mol for C_(2)H_(6))validates the facility of adsorbent regeneration.Furthermore,theoretical calculations demonstrate the C_(2)H_(6) molecules are trapped in the nonpolar pore surface via C–H···πand C–H···O interactions between multiple hydrogen atoms of C_(2)H_(6) and the host framework. | Sisi Jiang Liangying Li Lidong Guo Changhua Song Qiwei Yang Zhiguo Zhang Yiwen Yang Qilong Ren Zongbi Bao | 2021 | Science China Chemistry2021，64，4： | 1 |

As of April 15, 2022, more than 500 million cases of COVID-19 had been reported, with more than 6 million deaths. The ultimate arsenal to fight against this pandemic is highly effective vaccines (Bok et al.,2021;Sadarangani et al., 2021). | Zhiliang Hu Yi Yin Kai Wang Miaomiao Xu Chengyuan Ding Yan Song Changhua Yi Junwei Li Yongxiang Yi Zhihang Peng | 2022 | Science China(Life Sciences)2022，65，12： | 0 |
| 15 | Hydrogen-bonded metal-nucleobase frameworks for highly selective capture of ethane/propane from methane and methane/nitrogen separation显示文摘The separation of light hydrocarbons,including C_(2)H_(6)and C_(3)H_(8),is essential to natural gas upgrading.Meanwhile,N_(2)removal from CH_(4)is also crucial to concentrating low-quality coalbed methane,but the adsorption process is challenging because of the close kinetic diameter.This work reports two hydrogen-bonded metal-nucleobase frameworks(HOF-ZJU-201 and HOF-ZJU202)capable of efficiently separating C_(3)H_(8)/CH_(4),C_(2)H_(6)/CH_(4),and CH_(4)/N_(2).Due to strong affinity for C_(3)H_(8)and C_(2)H_(6),the lowpressure capacity for C_(3)H_(8)(5 kPa)and C_(2)H_(6)(10 kPa)of HOF-ZJU-201a exceeds most adsorbents.The ideal adsorbed solution theory(IAST)selectivity of C_(3)H_(8)/CH_(4)and C_(2)H_(6)/CH_(4)is 119 and 45 at ambient conditions.According to density functional theory calculations,surface polarization environments formed by electron-rich anions and electron-deficient purine heterocyclic rings contribute to the selective capture of C_(3)H_(8)and C_(2)H_(6)with greater polarizability.Furthermore,the high CH_(4)adsorption capacity(1.73 mmol/g for HOF-ZJU-201a and 1.50 mmol/g for HOF-ZJU-202a at 298 K and 1.0 bar)and excellent CH_(4)/N_(2)selectivity(6.0 for HOF-ZJU-201 at 298 K),as well as dynamic breakthrough experiments of binary CH_(4)/N_(2)gas mixture implied their efficacy in the concentration of low-quality coalbed methane. | Ying Liu Qianqian Xu Lihang Chen Changhua Song Qiwei Yang Zhiguo Zhang Dan Lu Yiwen Yang Qilong Ren Zongbi Bao | 2022 | Nano Research2022，15，8： | 0 |
