引用

Progress in Natural Science:Materials International 2018年第2期28卷 183-188页

作者： Xiangdong kang Yuyang kang Xingxing hong Zhenhua Sun Chao Zhen Chaohao Hu Gang liu Huiming Cheng Shenyang National Laboratory for Materials Science Institute of Metal Research Chinese Academy of Sciences Guangxi key Laboratory of Information Materials Guilin University of Electronic Technology School of Materials Science and Engineering University of Science and Technology of China Low-Dimensional Material and Device Laboratory Tsinghua-Berkeley Shenzhen Institute Tsinghua University Center of Excellence in Environmental Studies King Abdulaziz University

Extending visible light absorption range and suppressing the recombination of photogenerated charge carriers are always important topics in developing efficient solar-driven photocatalysts. In this study, the thermal treatment process at 400 °C in a high-pressure hydrogen atmosphere was applied to modify graphitic carbon nitride. Compared to the normal atmospheric hydrogen treatment process, this process has the merit of producing nitrogen deficient graphitic carbon nitride in high-yield. The optimal photocatalytic activity of modified graphitic carbon nitride was demonstrated by controlling the treatment duration in the hydrogen *** changes in the crystal structure, microstructure and optical properties of carbon nitrides were investigated by several characterizations. The relationship between the photocatalytic activity and structures of graphitic carbon nitride was preliminarily established. The results obtained in this study could provide some new ways of improving the activity of graphitic carbon nitride based photocatalyst.

作者： Bo Ren Rui-Feng Zhao Zhong-Xia liu Shao-kang Guan hong-Song Zhang School of Materials Science and Engineering Zhengzhou University School of Mechanical Engineering Henan Institute of Engineering

In this article, the microstructure, hardness, and corrosion resistance of the Al0.3CrFe1.5MnNi0.5Tixand Al0.3CrFe1.5MnNi0.5Six（x = 0, 0.2, 0.5, 1.0） high-entropy alloys were investigated via X-ray diffraction（XRD）scanning electron microscopy（SEM）, digital display Vickers hardness tester, and electrochemical technique These alloys are mainly composed of BCC solid-solution structure. When adding high content of Ti or Si elemen（x C 0.5）, some intermetallic compounds are found in the microstructure, which makes the alloys have a high hardness, high brittleness, and easy cracking. While the alloys with low content of Ti or Si（x = 0.2） have a hardness of HV 420–HV 430, and its hardness increases about 14 %compared with that of Al0.3CrFe1.5MnNi0.5. Electrochemical results in 3.5 % NaCl solution show that the alloying elements Ti and Si have a negative influence on the corrosion resistance of the Al0.3CrFe1.5MnNi0.5alloys.

Preparation and Unimolecular-Micellization Behavior of Homopolymer of Surface-Active Monomer AMC14AB

引用

Chinese Journal of Chemical Physics 2008年第5期21卷 469-475页

作者： kang-kai liu Lei Li Institute of Coal Chemistry Chinese Academy of Sciences Taiyuan 030001 China Economy and Commerce Committee of Shanxi Province Taiyuan 030001 China

（2-acrylamido） ethyl tetradecyl dimethylammonium bromide （AMC14AB） was polymerized in aqueous solu- tion to form the homopolymer P（AMC14AB）. The physicochemical properties of P（AMC14AB） in aqueous solution were mainly studied with fluorescent probe method, surface tension measurement and conductom- etry. The experimental results show that the aggregation morphology of P（AMC14AB） in aqueous solution is unimolecular micelle as expected. Being different from conventional multimolecular micelle systems, the unimolecular micelle system of P（AMC14AB） not only shows critical micellar concentration （CMC=0）, （i.e. once added to pure water, the surface tension decreases immediately in spite how small the density is）, but also the surface tension stays almost the same with the concentration increasing. That is to say, there is no mutational point on the relationship curve between surface tension and concentration. Furthermore, the unimolecular micelle system of P（AMC14AB） has no Krafft temperature, i.e. at any temperature, so long as it is dissolved in water, the unimolecular micelles will form. Besides this, for the solubilization of hydrophobic organic substances, the unimolecular micelle system of P（AMC14AB） is obviously different from the common multimolecular micelle system, having no turning point on the relationship curve between toluene solubi- lizaion amount and P（AMC14AB） concentration, and the solubilizing ability of the unimolecular-micelle system of P（AMC14AB） for hydrophobic organic substances is much higher than that of the conventional multimolecular micelle solutions of common surfactants, such as centyl trimethyl ammonium bromide.
