Preparation, modification and electrochemical properties of LiNi 0.8 Co 0.1 Mn 0.1 O 2 cathode material

LiNixCoyMn1-x-yO2作为层状正极材料，同时具有层状钴酸锂、镍酸锂和锰酸锂材料的优点。因其具有的成本低、容量高和环境污染小等特点，已经在某些应用上取代传统的钴酸锂正极材料。尽管如此，让LiNixCoyMn1-x-yO2具有更高的能量密度、循环稳定性和热稳定性仍是亟待解决的需求。 本论文选取Ni含量高的LiNi0.8Co0.1Mn0.1O2为研究对象，对其合成与表面修饰进行研究。本论文首先采用共沉淀法合成前驱体Ni0.8Co0.1Mn0.1(OH)2，然后高温煅烧出产品，通过优化合成条件，以获得类球形、电化学性能良好的LiNi0.8Co0.1Mn0.1O2正极材料；利用Li2MnO...The Ni-baesd layered cathode materials, such as LiNixCoyMn1-x-yO2 (NCM), have been considered as one kind of promising cathode material. They posess the similar advantages of layered LiCoO2, LiNiO2 and LiMnO2. The Ni-based layered cathode materials have replaced LiCoO2 in some fields due to their low cost, high energy density and low toxicity.

Design and Implementation of the Supervision of Investigation Management Information System

侦查机关日常侦查行为需要人民检察院对其行使监督权。包括立案监督、侦查活动监督和审查逮捕，是检察权的重要内容。它与审判监督、刑事判决裁定监督、执行监督共同构成刑事诉讼与法律监督的有机整体。基于侦查监督在惩罚犯罪、保障人权方面的重要性，强化侦查监督工作是推进“依法治国”的重要举措。以规范和约束公权力为重点，加大各级检察院对公安机关立案监督力度，通过侦查监督管理系统的建设，推进法治建设的规范化和科学化，实现数据共享，并建立大数据库，提升政法机关信息化管理水平。 系统采用UML进行面向对象的建模方式，将数据和处理组合起来，将其封装成对象，系统中的任何改变都可以在这些对象中完成，使系统有良好的可维护性...Investigation supervision is the people's procuratorate investigation of the investigation organ activities whether legitimate exercise of supervision, including filing supervision, investigation activities arrest is an important content of procuratorial supervision and examination.

Effects of Biochar Application on Nitrogen and Phosphorus Availability in Soils: aReview

利用生物炭在贫瘠的土壤上培育出肥沃的"黑土"正成为土壤学家研究的热点.氮、磷等大量养分是衡量土壤肥力高低的重要指标,生物炭对其有效性影响表现出极大的复杂性.不同研究得出的结论不尽相同,关键是缺乏对其机制的深入研究.由于氮和磷的不合理利用还可能造成非点源污染而带来环境风险,再加之生物炭施用的不可逆性,必须确保生物炭在任何情况下都不会对土壤和环境带来不利的影响.为此,本文综述了生物炭添加对氮肥和磷肥在土壤-植物系统迁移转化过程中的作用,重点讨论了不同生物炭处理方式对土壤磷素吸附解吸和形态转化的影响,生物炭对土壤氮素转化的关键过程(矿化作用、硝化作用和固持作用)的影响,以及生物炭C/N比值对土壤氮素..

Studies on Nano Cerium Oxides Catalyzed-oxidation of Lignin into Aromatic Compounds

基于木质纤维素的生物炼制，不仅能可持续地提供能源和化学品，也可以有效减少温室气体的净排放，为巨量的农业废弃物的高附加值转化提供最佳解决方案。然而，由于木质素是一种结构复杂、性质稳定、难溶、难解聚的芳香高分子，且与纤维素通过物理-化学作用紧密伴生，分离成本昂贵，转化利用困难，成为生物炼制的瓶颈之一。通过对木质素氧化解聚策略和机理的研究，使木质素定向氧化解聚为高附加值的芳香醛/酮/酸等化合物，是提高生物炼制经济性的根本途径。以二氧化铈为代表的部分稀土纳米氧化物在木质素的定向催化氧化反应中表现出优异性能，然而目前对它们的构效关系和催化机理的认识不足。基于此，本报告通过研究催化剂的设计，首先以纳米Ce...Biorefinery of lignocellulose not only provides the sustainable energy and chemicals, but also reduces the net emissions of greenhouse gases, and provides the best solution for high-value utilization of a huge amount of agricultural waste. However, lignin is a stable and recalcitrant aromatic polymer with complex structure, and closely associated with cellulose through physical-chemical interactio...学位：博士后院系专业：化学化工学院_化学工程学号：201317004

Research on facial spectrum and color characteristics of five-zang disease status

目的:观察疾病状态人群面色光谱色度情况,为疾病状态五脏病评价提供可供依据。方法:采用日产柯尼卡美能达CM-2600d分光测色仪,观测健康组(183例)、疾病组(370例)额部、眉间部、鼻部、下颏、左右颧部、左右眼胞8处明亮度l、红光度A、黄光度b、饱和度C值及波长段(400~700nM)下的面色反射率值等指标,并据中医理论对疾病状态进行五脏病位分析。结果:疾病组l值显著低于健康组,b、C值均显著高于健康组;疾病组各波长段下反射率显著低于健康状态组(P<0.05)。疾病组除左右眼胞外的6个位点间的l、A、b、C值有显著性差异(P<0.05),不同点位有其特异性的色度变化特征。疾病组五脏病各组光谱色度特征比较有显著差异(P<0.05),结果与中医面部脏腑五色理论在一定程度上相符合。结论:运用光谱色度测定方法,可以作为诊断疾病状态五脏病的重要指标。Objective: To observe disease status facial spectrum and color,providing good quantitative basis for disease assessment.Methods: We gathered the facial color information in health(183) and disease groups(370) including L,a,b,C values and reflection of different wavelengths in 400-700nm with CM-2600D spectral photometric color measuring instrument on 8 points including frontal part,glabellas nose,mandible two cheeks and eye cells and analysized disease status five-zang positioning according to the principle of TCM syndrome differentiation.Results: L value of Disease group was lower than health status group and b,C values were higher than health status group,reflection of different wavelengths of disease group were lower than health group(P<0.05).6 points in disease group between loci L,a,b,C values with varying degrees of significant differences(P<0.05).Different point had its own specificity facial complexion variation characteristics.Facial spectrum and color of each five-zang disease group had significant difference through comparion of facial complexion.To a certain extent the result was consistent with TCM facial organs Five-color theory.Conclusion: There existed diagnostic value in distinguishing five-zang disease status in some degree by spectral photometric color measuring technique.国家科技支撑计划(No.2012BAI37B06);国家高技术研究发展计划(863计划)资助项目(No.2008AA02Z407);国家自然科学基金资助项目(No.30873463;No.81173200);国家自然基金青年项目(No.81102558);上海市重点学科(第三期)建设项目(No.S30302;No.S30303)---
