The Research and Fabrication of Silicon-based Light Emitting Materials and Si-MSM-PD with Better Performance

硅是目前世界上矿藏最丰富且微电子工艺最成熟的半导体材料，也是光电集成最理想的半导体材料。但是由于硅具有间接带隙，跃迁几率很低，引起硅的发光效率极低，并且发光不稳定，因此硅基发光一直是硅光电集成中最重要的难题。另外，为实现全硅光电集成，硅探测器在光互连，大容量通讯等领域中具有深远的应用前景。硅MSM结构光电探测器工艺简单，与CMOS等工艺兼容，是硅光电集成研究的一个热点。但是，由于硅本身对光的吸收系数比较低引起对光的吸收长度较长，从而引起硅MSM结构光电探测器响应速率和响应度不高。本文针对以上两个问题进行了研究，并为硅基光电单片集成做准备工作：一．多孔硅发光的制备和钝化研究。硅的发光效率低及不稳...Silicon based optoelectronic devices have been investigated greatly, because of the great advantages afforded by this approach: an available well-developed and widespread technology, monolithic integration with control/driving electronics and low cost.

Advances in Research of Silicon-based Anode Materials for Lithium Ion Batteries

硅作为地球上储量丰富的材料,因为其具有较高的理论比容量和较低的电压平台而成为最有前途的锂离子电池负极材料.但是,硅负极材料具有较大的体积膨胀效应、低电导率、循环性能差等特点,成为阻碍其商业化的最大障碍.研究者们采取了各种方法来克服这些困难.本文总结了近期硅基负极材料通过纳米化、复合化、结构特殊化等方法来提高电池性能的最新进展,并展望硅基负极材料的发展方向.Silicon materials are attractive candidates for the next generation of lithium-ion batteries due to their high capacity, low operation potential, high abundance in the world.The main challenges for the practical implementation of silicon anodes, however, are the huge volume variation during lithiation and delithiation process and the low cycle life.Recently, significant works have been done to overcome the problems.Here, the research progresses in the silicon based anode materials for Li-ion batteries are reviewed; the problems and prospects for these materials are also discussed.国家自然科学基金项目(61176050

The Preparation of Three-dimensional Porous Silicon by Metal-assisted Chemical Etching

以工业级多晶硅粉为原料,采用金属银诱导化学腐蚀的方法制备出三维多孔硅纳米线结构。系统分析了化学腐蚀硅粉的机理,特别是金属银催化剂对制备过程的影响。实验对比了不同腐蚀条件(腐蚀液温度、沉积银溶液浓度、光照条件等)对样品结构形貌和比表面积的影响。研究发现,腐蚀液温度升高有利于腐蚀过程中化学反应的进行;而沉积银溶液中的Ag nO3浓度适中,有利于样品表面形成分布均匀的孔洞;外部光照可增加光生载流子,促进反应进行,加快腐蚀速率,从而提高样品比表面积。通过优化腐蚀条件,得到形貌较优、比表面积较大(530CM2·g-1)的三维多孔硅纳米线结构。Three-dimensional porous silicon was fabricated by metal-assisted chemical etching of commercial polycrystalline silicon particles.The mechanism of etching process especially the effects of Ag catalyst on the formation of porous silicon were systematically investigated.The dependence of the morphologies of the etched structures on the temperature of etching solution, the outside illumination and the metal salt concentration were also discussed.By optimizing the etching conditions, three-dimensional porous silicon-nanowires with best morphology and highest specific surface area( 530 cm2·g-1) was obtained.国家自然科学基金资助项目(61176050); 福建省中青年教师教育科研项目(JA15651

Direct Reductive Cyanation of A 2-Pyrrolidinone Chiral Building Block Bearing An Unprotected Hydroxyl Group: A Stereoselective Synthesis of N-Methyl-2-epi-bulgecinine

报道手性合成砌块(4S,5R)-N-芐氧基-5-羟甲基-2-吡咯烷酮(3a)的直接还原氰基化及产物的立体化学与转化研究.含未保护羟基的内酰胺用L; iAlH_4/KCN体系直接还原氰基化,生成比例为69:; 31的2,5-反式/顺式非对映立体异构体.与文献类似结果对比显示,氰基负离子对5-羟甲基-△-1-吡咯啉鎗中间体的加成主要受立体电子效应和C(5; )位取代基(羟甲基)与进攻试剂间烯丙型1,3-位阻控制.该混合物在碱性条件下水解,生成比例为10:; 90的2,5-反式/2,5-顺式-bulgecinine衍生物.这一结果表明氰基水解反应伴随着在C(2)位发生了有合成价值的串联差向异构化.由此; 建立了立体选择性地合成2,5-顺式(-)-N-甲基-2-别-bulgecinine的简便方法.The direct reductive cyanation of N-benzyl-4-benzyloxy-5-hydroxymethyl-2-pyrrolidinone (3a), a lactam bearing a free hydroxyl group, has been achieved with the LiAlH4/KCN combination. The reaction afforded 2,5-trans-2-cyano-5hydroxylmethyl-4-benzyloxy-pyrrolidine (5a) and its cis-diastereomer 5b in a ratio of 69: 31 with a combined yield of 63%. The observed 2,5-trans-stereoselectivity is suggested to be resulted from both stereoelectronic effect and allylic 1,3-strain between the hydroxymethyl group at C(5) and the incoming cyanide anion on the presumed Delta-1 pyrrolinium ion intermediate. The subsequent hydrolysis of the cyano group of the diastereomeric mixture 5a/5b (trans: cis=69: 31) under basic conditions afforded the corresponding 5-hydroxymethyl-4-benzyloxyproline with 2,5-cis-diastereomer as the major diastereomer (trans: cis= 10: 90). This result implies that a synthetically useful epimerization at C(2) has occurred concomitantly. This unexpected result afforded a concise and highly stereoselective synthesis of 2,5-cis-(-)-N-methyl-2-epi-bulgecinine.National Natural Science Foundation of China [21332007]; Program for; Changjiang Scholars and Innovative Research Team in University of; Ministry of Educatio

Assessment of impact of intensive livestock cultivation on water environment in mountain and hilly areas of South China

[摘要]选择南方山地丘陵区典型规模畜禽养殖集中地为研究区域, 通过对该研究区域周边地表水及地下水的 调查采样, 分析主要污染物时空变异及污染物形态之间的变化, 并对周边水环境进行初步评价。结果表明: 规模化畜禽养殖区域的浅层地下水和地表水已经受到严重污染; 养殖场的环保处理设施与养殖规模不配套 造成大量污染物进入地表水环境; 生物氧化塘的护堤和塘底未经防渗处理, 造成下游地下水污染; 养殖场排 放的污水经厌氧和好氧生物处理后富含有机质、氨氮、可溶态有机磷, 利于作物吸收和生长, 应尽量循环使 用。指出由于养殖污水变化较大, 为避免二次环境污染, 必须处理达标后结合配方施肥技术按需回用农田。[Abstract]By selecting a typical site of intensive livestock cultivation in a mountain area of South China as the study area, and investigating and sampling surface and groundwater in the study area, the spatial and temporal variat ions of the main pollutants and changes among pollutant forms were analyzed. The environmental effects of intensive livestock cultivation on surrounding water environments were evaluated. The results indicated that the shallow groundwater and surfacewater were heavily contaminated in the intensive livestock cultivation area. Large amounts of the pollutants entered the surface water, due to the fact that the wastewater treatment facility did not match the scale of livestock cult ivation. The lack of liner treatment of the bank and liner of the lagoon resulted in groundwater pollution. The effluent wastewater from the culturing farm after anaerobic and aerobic biologic treatment was full of organic matter, ammonia nitrogen, and dissolved organic phosphorus, which aided the growth of plants and should be recycled. Because of the significant change of the wastewater component, and in order to avoid secondary pollution, the wastewater should be recycled to land combined with precision fertilizer formula technology after treatment to bring it to the standard.福建省重大科技项目(2002H009)；福州大学人才基金项目(XRC-0611
