| 1 | Structural and photoluminescent properties of ZnO films deposited by radio frequency reactive sputtering显示文摘Zinc oxide films with c-axis preferred orientation were deposited on silicon (100) substrates by radio frequency (RF) reactive sputtering. The properties of the sam- ples were characterized by X-ray diffractometer, X-ray photoelectron spectroscopy and fluorescent-spectrophotometer. The effect of sputtering power and substrate temperature on the structural and photoluminescent (PL) properties of the ZnO films was investigated. The results indicated that when the sputtering power is 100 W and the substrate temperature is 300-400℃, it is suitable for the growth of high c-axis orientation and small strain ZnO films. A violet peak at about 380 nm and a blue band at about 430 nm were observed in the room temperature photolumines- cence spectra, and the origin of blue emission was investigated. | PENG XingPing WANG ZhiGuang SONG Yin JI Tao ZANG Hang YANG YingHu JIN YunFan | 2007 | Science China(Physics,Mechanics & Astronomy)2007，50，3： | 1 |

| 3 | Microscopic pore-fracture configuration and gas-filled mechanism of shale reservoirs in the western Chongqing area,Sichuan Basin,China显示文摘Taking the Upper Ordovician Wufeng Formation to Lower Silurian Longmaxi Formation shale reservoirs in western Chongqing area as the study target,the argon ion polishing scanning electron microscope and nuclear magnetic resonance(NMR)experiments of different saturated wetting media were carried out.Based on the image processing technology and the results of gas desorption,the pore-fracture configuration of the shale reservoirs and its influence on gas-filled mechanism were analyzed.(1)The reservoir space includes organic pores,inorganic pores and micro-fractures and there are obvious differences between wells in the development characteristics of micro-fractures;the organic pores adjacent to the micro-fractures are poorly developed,while the inorganic pores are well preserved.(2)According to the type,development degree and contact relationship of organic pore and micro-fracture,the pore-fracture configuration of the shale reservoir is divided into four types.(3)Based on the differences in NMR T_(2) spectra of shale samples saturated with oil and water,an evaluation parameter of pore-fracture configuration was constructed and calculated.The smaller the parameter,the better the pore-fracture configuration is.(4)The shale reservoir with good pore-fracture configuration has well-developed organic pores,high porosity,high permeability and high gas content,while the shale reservoir with poor pore-fracture configuration has micro-fractures developed,which improves the natural gas conductivity and leads to low porosity and gas content of the reservoir.(5)Based on pore-fracture configuration,from the perspective of organic matter generating hydrocarbon,micro-fracture providing migration channel,three types of micro gas-filled models of shale gas were established. | FU Yonghong JIANG Yuqiang DONG Dazhong HU Qinhong LEI Zhi'an PENG Hao GU Yifan MA Shaoguang WANG Zimeng YIN Xingping WANG Zhanlei | 2021 | Petroleum Exploration and Development2021，48，5： | 0 |
| 4 | Characterization of ZnO:In Film Prepared by Radio Frequency Sputtering显示文摘Wide band-gap semi-conducting compounds are very attractive in recent years because of the intense commercial interest in developing practical short wavelength semiconductor diode lasers for the huge market needs. ZnO has a wide band gap (3. 37 eV) and a large binding energy (60 meV) that allows efficient UV emission from excitation and makes it suitable for UV laser-emitting devices. Indium-doped ZnO (ZnO:In) films have been investigated by many researchers. It has lower electrical conductivity and bet- | Peng Xingping, Wang Zhiguang, Zang Hang, Song yin, Zhang Liqing Sheng Yanbing and Jin Yunfan | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |

| 6 | A novel strategy for the construction of silk fibroin–SiO_(2)composite aerogel with enhanced mechanical property and thermal insulation performance显示文摘The practical application of silica aerogels is an enormous challenge due to the difficulties in improving both mechanical property and thermal insulation performance.In this work,silk fibroin was used as scaffold to improve the mechanical property and thermal insulation performance of silica aerogels.The ungelled SiO_(2)precursor solution was impregnated into silk fibroin to prepare silk fibroin-SiO_(2)composite aerogels via sol−gel method followed by freeze-drying.By virtue of the interfacial hydrogen-bonding interactions and chemical reactions between silk fibroin and silica nanoparticles,SiO_(2)was well-dispersed in the silk fibroin aerogel and composite aerogels exhibited enhanced mechanical property.By increasing the loading of silk fibroin from 15 wt%to 21 wt%,the maximum compressive stress was enhanced from 0.266 to 0.508 MPa when the strain reached 50%.The thermal insulation performance of the composite aerogels was improved compared with pure silica aerogel,as evidenced that the thermal conductivity was decreased from 0.0668 to 0.0341 W∙m‒1∙K‒1.Moreover,the composite aerogels exhibited better hydrophobicity and fire retardancy compared to pure silica aerogel.Our work provides a novel approach to preparing silk fibroin-SiO_(2)composite aerogels with enhanced mechanical property and thermal insulation performance,which has potential application as thermal insulation material. | Weixin Liu Bo Yin Jie Zhang Xingping Liu Wenxian Lian Shaokun Tang | 2023 | Frontiers of Chemical Science and Engineering2023，17，3： | 0 |
