| 1 | 沸石咪唑酯骨架结构材料ZIF-8催化Friedel-Crafts酰基化反应(英文)显示文摘A zeolite imidazolate framework,ZIF-8,was synthesized and characterized by dynamic laser light scattering,X-ray powder diffraction,scanning electron microscopy,transmission electron microscopy,thermogravimetric analysis,Fourier transform infrared,atomic absorption spectrophotometry,and nitrogen adsorption measurements.The ZIF-8 was highly crystalline and porous with a surface area of over 1600 m2 /g.Friedel-Crafts acylation of anisole and benzoyl chloride proceeded well in the presence of ZIF-8(2-6 mol%) without the need for an inert atmosphere.The reaction afforded a selectivity of 93%-95% to the p-isomer.The solid catalyst can be separated from the reaction mixture by simple centrifugation and reused without significant degradation in catalytic activity.There was no leaching of active acid species into the reaction solution. | Lien T.

| 2 | Friction characteristics of mechanically exfoliated and CVD-grown single-layer MoS_2显示文摘In this work, the friction characteristics of single-layer MoS_2 prepared with chemical vapor deposition(CVD) at three different temperatures were quantitatively investigated and compared to those of single-layer MoS_2 prepared using mechanical exfoliation. The surface and crystalline qualities of the MoS_2 specimens were characterized using an optical microscope, atomic force microscope(AFM), and Raman spectroscopy. The surfaces of the MoS2 specimens were generally flat and smooth. However, the Raman data showed that the crystalline qualities of CVD-grown single-layer MoS2 at 800 °C and 850 °C were relatively similar to those of mechanically exfoliated MoS2 whereas the crystalline quality of the CVD-grown single-layer MoS_2 at 900 °C was lower. The CVD-grown single-layer MoS_2 exhibited higher friction than mechanically exfoliated single-layer MoS_2, which might be related to the crystalline imperfections in the CVD-grown MoS_2. In addition, the friction of CVD-grown single-layer MoS_2 increased as the CVD growth temperature increased. In terms of tribological properties, 800 °C was the optimal temperature for the CVD process used in this work. Furthermore, it was observed that the friction at the grain boundary was significantly larger than that at the grain, potentially due to defects at the grain boundary. This result indicates that the temperature used during CVD should be optimized considering the grain size to achieve low friction characteristics. The outcomes of this work will be useful for understanding the intrinsic friction characteristics of single-layer MoS2 and elucidating the feasibility of single-layer MoS_2 as protective or lubricant layers for micro- and nano-devices. | Dinh Le Cao KY Bien-Cuong TRAN KHAC Chinh Tam LE Yong Soo KIM Koo-Hyun CHUNG | 2018 | Friction2018，6，4： | 9 |
