The Effects of Internal Electron Donors on MgCl2-Supported Ziegler–Natta Catalysts for Isotactic PP
Autor: Bin Li, Huashu Li, Hongfan Hu, Yi Zhou, Guoliang Mao, Shixuan Xin
Publikováno v: Polymers, Vol 16, Iss 19, p 2687 (2024)
The electron donors (ED) in Ziegler–Natta (Z-N) catalysis are classified as internal electron donors (IED) and external electron donors (EED), and both IED and EED are indispensable components for enhancing the catalytic reactivity and regulating t

PNP-Ligated Rare-Earth Metal Catalysts for Efficient Polymerization of Isoprene
Autor: Rongqing Ma, Hongfan Hu, Xinle Li, Yi Zhou, Huashu Li, Xin Sun, Xueqin Zhang, Guoliang Mao, Shixuan Xin
Publikováno v: Catalysts, Vol 12, Iss 10, p 1131 (2022)
The tridentate PNP ligand-supported rare-earth metal complexes, i.e., bis[o-diphenylphosphinophenyl]amido-Re-bis[o-dimethylaminobenzyl], [(Ph2P-o-C6H4)2N]Re[(CH2-o-Me2N(C6H4))2]: (Re = Y, 1; Nd, 2; Gd, 3) were applied to isoprene polymerization. When

Vegetation and climate changes since the middle MIS 3 inferred from a Wulagai Lake pollen record, Inner Mongolia, Northeastern China
Autor: Ulrike Herzschuh, Xingqi Liu, Yong Wang, Huashu Li, Zhitong Yu, Xianyong Cao
Publikováno v: Review of Palaeobotany and Palynology. 262:44-51
The climate conditions during Marine Isotope Stage (MIS) 3 were similar to present-day conditions, but whether humidity then exceeded present levels is debated, and the driving mechanisms of palaeoclimate evolution since MIS 3 remain unclear. Here, w

Mass 47 clumped isotope signatures in modern lacustrine authigenic carbonates in Western China and other regions and implications for paleotemperature and paleoelevation reconstructions
Autor: Aradhna Tripati, Huashu Li, Ben Elliott, Xingqi Liu, Anne Marie Kelley, Alexandrea Arnold, Randy Flores
Publikováno v: Earth And Planetary Science Letters (0012-821X) (Elsevier BV), 2021-05, Vol. 562, P. 116840 (12p.)
With the development of the carbonate clumped isotope () geothermometer, many –temperature calibrations based on biogenic and abiogenic carbonates have been generated in recent years. However, there is still not a robust empirical calibration relat

Factors controlling the oxygen isotopic composition of lacustrine authigenic carbonates in Western China: implications for paleoclimate reconstructions
Autor: C. Whicker, Xingqi Liu, Anne Marie Kelley, Alexandrea Arnold, Huashu Li, Shengnan Feng, Aradhna Tripati, Ben Elliott
Publikováno v: Scientific Reports (2045-2322) (Springer Science and Business Media LLC), 2020-10, Vol. 10, N. 1, P. 16370 (17p.)
Scientific Reports, Vol 10, Iss 1, Pp 1-17 (2020)
In the carbonate-water system, at equilibrium, the oxygen isotopic composition of carbonate is dependent not only on the temperature but also on the isotopic composition of host water in which the carbonate is formed. In this study, lake surface sedi

Impact of hydrological conditions on the radiocarbon reservoir effect in lake sediment 14C dating: the case of Kusai Lake on the northern Qinghai-Tibet Plateau
Autor: Qi Zhang, Huashu Li, Xingqi Liu
Publikováno v: Quaternary Geochronology. 62:101149
The hydrological conditions of a lake system strongly influence the reservoir effect in the radiocarbon dating of endogenic organic and inorganic carbon in lake sediments. In this paper, we compare 14C dating with varve counting results for cores fro
