| 1 | Growth of LaBr_3:Ce^(3+) Single Crystal by Vertical Bridgman Process in Nonvacuum Atmosphere显示文摘The growth of LaBr3:Ce3+ crystal by the vertical Bridgman process in a nonvacuum atmosphere was reported. According to the dehydration procedure of LaBr3·7H2O and CeBr3·7H2O investigated by differential thermal analysis/thermogravimetry (DTA/TG), anhydrous LaBr3 and CeBr3 were prepared by heating LaBr3·7H2O and CeBr3·7H2O at 240–260°C for 5–6 h in dried HBr atmosphere. Using the feed materials prepared from the anhydrous lanthanon bromides, a 0.5 mole fraction Ce3+ doped LaBr3 crystal with size of φ25 mm×50 mm had been grown by vertical Bridgman process successfully. By sealing the feed material in a platinum crucible, the crystal could be grown in a nonvacuum atmosphere as the oxidization and volatilization of the melt could be avoided. The crystal was grown with the optimum conditions such as a growth rate of 0.5–1.0 mm/h and a temperature gradient of around 30°C/cm across solid-liquid interface under a furnace temperature of 850–880°C. The crystal was characterized by DTA/TG, X-ray diffraction (XRD), optical transmission, photoluminescence and X-ray stimulated luminescence measurement. The Bridgman process was confirmed to be promising for growing transparent LaBr3:Ce3+ crystal with high optical quality. | Hongbing Chen Changyong Zhou Peizhi Yang Jinhao Wang | 2009 | Journal of Materials Science & Technology2009，25，6： | 6 |
| 2 | Petrography and chronology of lunar meteorite Northwest Africa 6950显示文摘Northwest Africa(NWA)6950 is an olivine-gabbro lunar meteorite that has a distinctly different petrographic texture from other lunar basalts.In this contribution,we report the petrography,mineralogy,and U-Pb geochronology of baddeleyite and phosphate in this lunar meteorite and make a comparison with other NWA 773 paired meteorites.NWA 6950 consists mainly of coarse-grained olivine,pyroxene,and plagioclase,with minor ilmenite,chromite,troilite,baddeleyite,taenite,and apatite.The abundant rounded to euhedral olivine has a limited Fo ranging from 68 to 69.Pyroxenes include both augite and pigeonite,with a narrow range of Mg#=71–80,and composition,respectively,En46-52Fs12-16Wo32-41 and En58-68Fs19-28Wo7-20.Plagioclase is mainly anhedral,conforming to the crystal margins of olivine and pyroxene.The plagioclase grains are elongated and several hundreds of microns in length.Raman spectra shows that plagioclase has been transformed into maskelynite,which is very calcic(An87-95)with low sodium and very low potassium(Ab4-9Or0.6-3.7).The weighted mean 207Pb/206Pb ages of baddeleyite and phosphate measured using a sensitive high resolution ion micro probe(SHRIMP II)are 3119±16 Ma(n=9,MSWD=2.5)(mean squared weighted deviates,MSWD)and 3119±18 Ma(n=15,MSWD=2.1),respectively,giving the crystallization age of the meteorite.NWA 6950 has similar mineral compositions,geochemical characteristics,and an almost identical age of crystallization to the magnesian gabbro of the NWA 773 clan.We conclude that NWA 6950 and NWA 773 are paired meteorites,which crystallize at ca.3119 Ma,and represent magmatic activities in the KREEP(potassium(K),rare earth elements(REE)and phosphorus(P)rich lunar material)region of the Moon. | Zemin BAO Yuruo SHI JLawford ANDERSON Allen KENNEDY Zuokai KE Xiangping GU Peizhi WANG Xiaochao CHE Yuelan KANG Huiyi SUN Chen WANG | 2020 | Science China(Information Sciences)2020，63，4： | 2 |

| 13 | Construction, photoelectric response and phase transition for new hybrid double perovskites showing narrow band gaps显示文摘To explore the lead-free key scientific issue in perovskite, double perovskite based on Ag Bi and Cu Bi was naturally selected as a competitive candidate due to its fascinating functional features, such as self-powered circularly polarized light detection, X-ray detection, photoluminescence and so on. However, the most challenging point is to simulate the structure and function of traditional lead-based perovskite in new double perovskite. At the same time, there are few suitable double perovskite systems with optical and electrical potential. The above two points greatly limit the competitiveness of double perovskite. In order to solve this problem, firstly, by analyzing and comparing previous studies,we used 2,2-dimethylpropan-1-aminium(abbreviated as 2,2-DPA) as the organic template to assemble materials. Solid-to-solid phase transition materials(2,2-DPA)3Bi2I91 and(2,2-DPA)3Pb2I72 were constructed. Along the path of lead-free and two-dimensional maintenance, we successfully synthesized(2,2-DPA)4AgBiI8.H_(2)O 3 and(2,2-DPA)_(4)CuBiI8.H_(2)O 4. As two typical semiconductors, 3 and 4 with narrower optical band gaps of 1.98 and 1.76 e V show obvious photo-response when the xenon lamp with intensity of 20 m W/cm^(2)is on or off, implying that they may be applied to light-harvesting and light-detecting devices. By referring to the phase transition mechanism of 1 and 2, 3 may be caused by ordered-disordered transition of the organic part, which was proven to be the first solid-to-solid phase transition material with <100>-oriented layered double perovskites with n = 1 by systematic characterization methods after dehydration for all we know. We believed that this work can provide meaningful guidance for the development of lead-free double perovskites. | Changyuan Su Zhixu Zhang Jie Yao Ming Chen Peizhi Huang Yi Zhang Dawei Fu Liyan Xie | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
| 14 | Multi-functional stainless steel composite frames stabilize the sodium metal battery显示文摘The sodium(Na)metal battery has the prospect of promising high energy density and sustainable tech-nology for low-cost energy storage.However,the soft texture and high reactivity of Na cause it easy to structure collapse and produce side reactions with organic electrolytes.Inspired by ancient Chinese ar-chitecture,a structural engineering strategy is introduced to conquer the above issues.PVDF film-covered stainless steel mesh(SMPF)embedded in the obverse of Na metal to form a“self-limiting”Na/electrolyte interface and bare stainless steel mesh(SM)with high electronic conductivity embedded in the reverse of Na metal to form a uniformly electronic distributed Na/collector interface.Based on the electric field simulation and in-situ optical tests,the well-designed structure of the SM@Na@SMPF electrode can re-strict the dendrite growth and slow down the bubbles release.The above strategies provide important technical support for the large-scale application of flexible Na metal batteries. | Laiping Li Yusheng Luo Wenlu Yuan Peizhi Mou Qi Wu Lin Zhang Yong Chen Jie Shu Liyuan Zhang | 2023 | Journal of Materials Science & Technology2023，，18： | 0 |
| 15 | Determination of Earthquake Fracture Feature by Using the Directional Function显示文摘In this paper,a new method for determining the earthquake fracture feature is put forward.The generalized directional function DG is defined as the ratio of P waveamplitude spectrums recorded at station 1 and station 2 by comparisonof the recorded DG curve and the theoretical curve,the ratio of fracture lengths of a bilateral fracture in two opposite directions and the angle between station 1 and the main rupture propagating direction can be determined simultaneously.Theoretically speaking,only records of three stations distributed homogeneously are needed to determine the fracture feature of an earthquake.The main rupturing propagating direction of a strong aftershock(ML5.4)of the Tangshan earthquake(Ms7.8)has been obtained by using the new method and has been compared with the result of the earthquake source mechanism.This shows that this new method is effective. | Liu Wenlong,Wu Peizhi,and Chen YuweiSeismological Bureau of Annul Province,Hefei 230031,China | 1996 | Earthquake Research in China1996，10，3： | 0 |
| 16 | Clinicopathological characteristics and genetic alterations in clear cell carcinoma cells derived from Mullerian duct epithelium of the prostate显示文摘Müllerian duct cysts of the prostate,which are common in young men,are relatively rare clinical complications.Moderately large cysts present with urinary obstruction,urinary tract irritation,subsequent frequent urination,urgency,and dysuria.Larger cysts can compress the seminal vesicles or ejaculatory ducts and cause intractable bloody sperms or obstructive azoospermia.Malignant transformation of Müllerian duct cysts is even rarer.Only 10 cases of Müllerian duct malignancies have been reported in previous studies.[1–9]We reported a case of one patient admitted to our center and discussed the clinicopathologic features,diagnosis. | Shaoan Chen Fengyun Cui Peizhi Zhang Li Chen Wei Song Qingchao Meng Xiude Chen Qinghua Xia Weiting Kang | 2022 | Chinese Medical Journal2022，135，20： | 0 |
| 17 | Hybrid Optical-Electrical Perovskite Can Be a Ferroelastic Semiconductor显示文摘Organic–inorganic hybrid perovskites(OIHPs)have been a hot research topic due to their advanced structural and functional features that cover almost all the research fields of intelligent materials including ferroelectric,photovoltaic,fluorescent,and dielectric.However,the development of the construction of an OIHP ferroelastic semiconductor with optical-electrical response has been a huge challenge and infrequently reported.In this work,a rare and interesting hybrid perovskite ferroelastic semiconductor,[BFDA]PbBr_(3)(BFDA=benzyl-(2-fluoro-ethyl)-dimethyl-ammonium),was synthesized,which benefits from the structural advantage of a long tail BFDA to be balanced by the suitable inorganic framework.[BFDA]PbBr_(3) shows a high-temperature ferroelastic phase transition at 365 K and a direct band gap of 3.33 eV.In addition,it can emit charming orange-pink light under a 365 nm UV lamp.To combine this with the ferroelastic,optical,and dielectric properties,[BFDA]PbBr_(3) can be identified as a very rarely reported ferroelastic semiconductor.The above-mentioned synthesis strategy is also helpful for the enrichment and development of the hybrid perovskite family. | Changyuan Su Mengmeng Lun Yidan Chen Yichen Zhou Zhixu Zhang Ming Chen Peizhi Huang Dawei Fu Yi Zhang | 2022 | CCS Chemistry2022，4，6： | 0 |
