| 1 | MoS_(2) on topological insulator Bi_(2)Te_(3) thin films:Activation of the basal plane for hydrogen reduction显示文摘2H-MoS_(2) is a well-studied and promising non-noble metal electrocatalyst for heterogeneous reactions,such as the hydrogen evolution reaction(HER).The performance is largely limited by the chemically inert basal plane,which is unfavorable for surface adsorption and reactions.Herein,we report a facile method to boost the HER activities of 2H-MoS_(2) by coupling with epitaxial Bi2Te3 topological insulator films.The as-obtained MoS_(2)/Bi2Te3/SrTiO3 catalyst exhibits prominent HER catalytic activities compared to that of pure MoS_(2) structures,with a 189 mV decrease in the overpotential required to reach a current density of 10 mA cm^(−2) and a low Tafel slope of 58 mV dec−1.Theoretical investigations suggest that the enhanced catalytic activity originates from the charge redistribution at the interface between the Bi2Te3topological insulator films and the MoS_(2) layer.The delocalized sp-derived topological surface states could denote electrons to the MoS_(2) layer and activate the basal plane for hydrogen adsorption.This study demonstrates the potential of manipulating topological surface states to design high-performance electrocatalysts. | Guowei Lia Jue Huang Qun Yang Liguo Zhang Qingge Mu Yan Sun Stuart Parkin Kai Chang Claudia Felser | 2021 | Journal of Energy Chemistry2021，30，11： | 1 |
| 2 | A method for Absolute Protein Expression Quantity Measurement Employing Insulator RiboJ显示文摘Measuring the absolute protein expression quantity for a specific promoter is necessary in the fields of both molecular biology and synthetic biology.The strength of a promoter is traditionally characterized by measuring the fluorescent intensity of the fluorescent protein downstream of the promoter.Until now,measurement of the absolute protein expression quantity for a promoter,however,has been unsuccessful in synthetic biology.The fact that the protein coding sequence influences the expression level for different proteins,and the inconvenience of measuring the absolute protein expression level,present a challenge to absolute quantitative measurement.Here,we introduce a new method that combines the insulator RiboJ with the standard fluorescence curve in order to measure the absolute protein expression quantity quickly;this method has been validated by modeling verification.Using this method,we successfully measured nine constitutive promoters in the Anderson promoter family.Our method provides data with higher accuracy for pathway design and is a straightforward way to standardize the strength of different promoters. | Hongbin Yu Zheng Wang Hanyue Xu Jiusi Guo Qingge Ma Xiangxu Mu Yunzi Luo | 2018 | Engineering2018，4，6： | 1 |
| 3 | Superconductivity in LaPd2Bi2 with CaBe2Ge2-type structure显示文摘Since the discovery of superconductivity in LaFeAsO1-xFx, the high-Tc iron-based superconductors have been extensively studied from both experimental and theoretical viewpoints [1-8].However,the mechanism of the unconventional superconductivity is still to be resolved.To address such issues,numerous 3d,4d,5d transition metal pnietide,silicide,germanide,chalcogenide materials crystalizing in the similar crystal structure with iron pnictide/ selenide suoerconductors were studied [9-24]. | QingGe Mu BoJin Pan BinBin Ruan Tong Liu Kang Zhao Lei Shan GenFu Chen ZhiAn Ren | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，12： | 0 |
| 4 | Magnetocatalysis:The Interplay between the Magnetic Field and Electrocatalysis显示文摘Magnetic fields are known as clean,economic,and effective tools to modify band and magnetic structures of materials.When coupled with catalytic processes such as the hydrogen evolution reaction(HER),they have the potential to control catalytic efficiency.Herein,we studied the magnetic response of a series of materials as HER catalysts,specifically ferromagnetic Co_(2)VGa,Co_(2)MnGa,and Ni,ferrimagnetic Mn_(2)CoGa,and paramagnetic Pt. | Guowei Li Qun Yang Kaustuv Manna Qingge Mu Chenguang Fu Yan Sun Claudia Felser | 2021 | CCS Chemistry2021，3，10： | 0 |
