多元文化视野下义务教育语文教材之国外文化要素透视——以人教版课程标准实验教材为例

语文是学校教育传承人类文化的主要阵地,具有特殊的思想教育功能,其课程资源的选择事关重要。从多元文化的视角分析,人教版义务教育阶段语文新教材中反映国外文化的作品体裁覆盖面广且重点突出,其所涉及的国外文化内容较丰富,呈现方式灵活多样且图文并茂。这种改革具有重要的导向意义和教育价值,同时也存在国外文化内容在空间与时间上的分布不均,差异性、系统性不够等问题。因此,要多维立体地反映世界各地文化,强化多元文化整合教育;回归"儿童本位"教育观,进一步优化课程设计;秉持多元文化教育理念,构建义务教育语文课程体系。     

无水溶胶凝胶法制备LiFe1-xCoxPO4/C正极材料及其性能研究

在无水溶胶凝胶法基础上,以Fe3+盐为铁源,添加聚乙二醇-400作为表面活性剂,制备了掺杂钴的LiFePO4/C正极材料(LiFe1-xCoxPO4/C,x=0,0.05,0.1)。并通过XRD、SEM、恒流充放电等方法研究了不同钴掺杂量对LiFePO4/C结构、形貌和电化学性能的影响。     

“大连会议”材料的注释

1962年8月中国作协主持召开的农村题材短篇小说创作座谈会（也称大连会议）,是当代文学史的重要事件。＂文革＂开始后,邵荃麟、侯金镜等以＂走资派＂、＂黑帮分子＂或＂修正主义分子＂的身份被审查、批判。他们的＂交代材料＂是巨大压力下的产物,对人、事的性质认定,以及事实的真实性等方面,存在需要细心辨析以判明真伪的问题。文章采取将材料加以简单编排,对某些部分加入批注的方式,是试图＂复现＂事件的某些细节,在＂历史＂的＂必然＂中见识＂偶然＂,以此增加对＂当代＂（＂十七年＂）文学权力机制运作的了解,也进一步认识这个时期文学界纠结并引发冲突的问题的症结。     

高级英语交互式教学模式探究

高级英语为英语专业高年级阶段的基础综合课,对提高英语专业高年级学生的英语综合能力无疑起着至关重要的作用。但其传统的教学模式很难抓住学生的注意力,使学生的英语综合技能得不到提高。交互性教学模式主张给学习者更多的参与机会来实践语言的实际应用,大大提高了学生学习的积极能动性,活跃了课堂气氛,有助于高级英语教学目标的实现。     

区域城市先进制造业现状分析与发展策略研究

粤港澳大湾区先进制造业基地建设对于中国制造业转型升级战略调整具有重要示范意义。通过构建先进制造能力评价体系,并对粤港澳大湾区9市进行对比分析。研究发现9市整体上具有良好产业基础,但仍存在科技创新能力、产业结构优化等问题,且具有产业发展动力不足、核心技术和人才匮乏、发展氛围欠佳和行业标准缺失等瓶颈。故此,基于生命周期理论度量9市先进制造业所处阶段,按照不同发展阶段提出产业协同、技术创新、产业融合和基础发展模式,从政府、企业和高校三方面提出应重视科研创新、产业结构优化、高新技术等问题解决的发展建议。     

Algorithm-improved high-speed and non-invasive confocal Raman imaging of 2D materials

Confocal Raman microscopy is important for characterizing 2D materials, but its low throughput significantly hinders its applications. For metastable materials such as graphene oxide (GO), the low throughput is aggravated by the requirement of extremely low laser dose to avoid sample damage. Here we introduce algorithm-improved confocal Raman microscopy (ai-CRM), which increases the Raman scanning rate by one to two orders of magnitude with respect to state-of-the-art works for a variety of 2D materials. Meanwhile, GO can be imaged at a laser dose that is two to three orders of magnitude lower than previously reported, such that laser-induced variations of the material properties can be avoided. ai-CRM also enables fast and spatially resolved quantitative analysis, and is readily extended to 3D mapping of composite materials. Since ai-CRM is based on general mathematical principles, it is cost-effective, facile to implement and universally applicable to other hyperspectral imaging methods.     

Postsynthetic functionalization of covalent organic frameworks

Covalent organic frameworks (COFs) have been at the forefront of porous-material research in recent years. With predictable structural compositions and controllable functionalities, the structures and properties of COFs could be controlled to achieve targeted materials. On the other hand, the predesigned structure of COFs allows fruitful postsynthetic modifications to introduce new properties and functions. In this review, the postsynthetic functionalizations of COFs are discussed and their impacts towards structural qualities and performances are comparatively elaborated on. The functionalization involves the formation of specific interactions (covalent or coordination/ionic bonds) and chemical reactions (oxidation/reduction reaction) with pendant groups, skeleton and reactive linkages of COFs. The chemical stability and performance of COFs including catalytic activity, storage, sorption and opto-electronic properties might be enhanced by specific postsynthetic functionalization. The generality of these strategies in terms of chemical reactions and the range of suitable COFs places them as a pivotal role for the development of COF-based smart materials.     

Construction of hollow mesoporous silica nanoreactors for enhanced photo-oxidations over Au-Pt catalysts

It is highly desirable to design hollow structures with multi-scale functions by mimicking cells for the construction of micro/nanoreactors. Herein, we report the construction of hollow-structured submicrometer-photoreactors with bimetallic catalysts loaded within mesoporous silicas. The synthesis parameters are optimized to study the evolution of hollow structure through hydrothermal treatment and an ‘adhesive-contraction’ formation mechanism is proposed. AuPt@HMZS catalysts exhibited a broader absorbance region under visible light and the adsorption edge displayed a red-shift, indicating the strong metal–metal interactions at the alloy interface. The reaction performance of the coupled Au-Pt catalysts can be tuned to achieve excellent catalytic activity in cinnamyl alcohol oxidation to cinnamic acid for 3.1 mmol g⁻¹ with 99% selectivity. The proposed strategy to build hollow structures as multifunctional micro/nanoreactors is promising for the design of high-performance and sustainable catalysts for chemical synthesis.
