| 1 | Synthesis, structure and luminescent properties of yellow phosphor La3Si6N11 :Ce^3+ for high power white-LEDs显示文摘A series of high phase purity blue light excitable yellow-emitting La_(3-x)Si_6 N_(11):xCe^(3+) phosphors were synthesized by the high temperature solid state reactions method. The structure and luminescent properties were investigated. The phase structure was studied by means of X-ray diffraction, structures refinements and energy dispersive X-ray spectroscopy. The phosphors effectively excited by the light of450 nm and show intense yellow emission at 535 nm with FWHM of 115 nm corresponding to the5 d →~2 F_(5/2) and 5 d →~2 F_(7/2) transitions of Ce^(3+). In addition,the optimized La_(2.86)Si_6 N_(11):0.14 Ce^(3+) exhibits a weak thermal quenching, which remains 98.2% of the initial emission intensity when heated to 200 ℃,the thermal quenching properties exhibit a modest decline when the temperature returned to room temperature. The above results indicate that La_3 Si_6 N_(11):Ce^(3+) can be regarded as a high promising phosphor for applications in high power white-light LED. | Fu Du Weidong Zhuang Ronghui Liu Yuanhong Liu Wei Gao Xia Zhang Yuan Xue Hongrui Hao | 2017 | Journal of Rare Earths2017，35，11： | 8 |
| 2 | The Influence of Paraffinic Base Oil on Low-temperature Viscosity of Naphthenic Base Oil显示文摘与底油和 naphthenic 底在不同集体比率上油的 paraffinic 混合的润滑剂油的低温度的粘性被实验测试了。naphthenic 库油的性能上的 paraffinic 库油的影响被学习测试的油的低温度的粘性调查。润滑剂油的粘性在油混合与高粘性的 paraffinic 底油的一个增加的内容增加了。并且当在混合的 paraffinic 底油的内容是不足道的时,低温度的粘性少些被影响。为了为提出润滑减少费用,上油,根据润滑油的性质能遇见说明, paraffinic 底油的小部分能被增加进 naphthenic 底油。根据与 paraffinic 底油混合的油和 naphthenic 底油的低温度的粘性上的学习,一条基本规则为润滑油限制的准备被得出。 | Liu Shuzhen Fu Hongrui | 2010 | China Petroleum Processing & Petrochemical Technology2010，12，1： | 2 |

| 4 | Development of a new hydrophobic magnetic biochar for removing oil spills on the water surface显示文摘More technologies are urgently needed for combined use to effectively eliminate the effect of oil spills,an environmental problem of widespread concern.Among these technologies,sorption methods are available to remove residual oil and prevent the further spread on the water surface.In this study,biochars,prepared from different feed-stock materials and pyrolysis temperatures,were screened and further modified to improve their application in the water environment.Among cornstalk biochar(CSBC),corncob biochar(CCBC),Sophora sawdust biochar(SSBC),and rice husk biochar(RHBC),the CSBC had excellent oil sorption capacity,especially prepared at 350℃(CSBC350),which has a complete and full pore structure.Furthermore,magnetic and silane agent modifications of CSBC350(OMBC)were performed to enhance the properties of the magnetic field controllability and hydrophobicity to increase oil sorption.The OMBC exhibited satisfactory oil sorption capacities to crude oil,diesel oil,and engine oil in the water-oil system of 8.77 g g^(−1),4.01 g g^(−1),and 4.44 g g^(−1),respectively.The sorption process of CSBC350 and OMBC complied with the pseudo-second-order kinetics(R^(2)>0.97)and the Langmuir isotherm models(R^(2)>0.80)based on the highest regression coefficients.The sorption mechanisms are dominated by hydrophobic forces,pore intercepts,and hydrogenbond interactions.The biochar adsorbent can availably cooperate with other physical methods to eliminate oil contaminants,which can be an outstanding fuel source for producing heat. | Xiaojun Sun Hongrui Fu Mutai Bao Wei Liu Chengyi Luo Yang Li Yiming Li Jinren Lu | 2022 | Biochar2022，4，1： | 0 |
