| 1 | Electrically Conductive Honeycomb Monolith of Nanolaminated Ti_3AlC_2:Preparation and Characterization显示文摘Nanolaminated Ti_3AlC_2 honeycomb monolith with parallel and uniform holes has been prepared through a facile extrusion route by using Ti_3AlC_2 powder as the main raw material.The fabricated honeycomb monolith has high compressive strength of 133 ± 11 and 59 ± 9 MPa,along and perpendicular to the extrusion direction,respectively.It also has good electrical conductivity,and excellent match of thermal expansion coefficient with the washcoat material of γ-AI_2O_3.These combined properties endow the honeycomb monolith a promising candidate as catalysis substrate for cleaning vehicle exhaust. | X.M.Fang X.H.Wang H.Zhang Y.C.Zhou | 2015 | Journal of Materials Science & Technology2015，31，1： | 5 |

| 3 | Raman Scattering Study of PbSe Grown on(111)BaF_(2) Substrate显示文摘PbSe films were grown on(111)-oriented BaF_(2)substrates by using molecular beam epitaxy.High resolution x-ray diffraction characterization showed good crystalline quality of PbSe films.Both longitudinal optical phonon at 135cm^(-1)and transverse optical phonon at 47.6cm-1 were observed by Raman scattering measurements.The Raman tensor calculation demonstrates that both transverse-optical and longitudinal-optical(LO)phonons in PbSe crystal are Raman active on(111)-oriented surface,Furthermore,2LO phonon at about 270cm^(-1)and polaron at about 800cm^(-1)in PbSe,were also observed.The observed Raman frequencies are in good agreement with theoretical calculations using point ion model. | 杨爱龄 吴惠桢 李志锋 邱东江 常勇 李剑锋 P.J.McCann X.M.Fang | 2000 | Chinese Physics Letters2000，17，8： | 0 |
