本文主要探讨通过一些生动有趣、贴近生活的化学实验教学,调动学生学习化学实验知识的积极性和主动性,提高学生的学习效率,从而增强对学生创新能力的培养.
微波消解技术是一种新兴的样品前处理技术,具有消解速度快、试剂用量少和环保等优点,在生物、环境和医药等多个领域有着广泛的应用.根据微波消解技术的特点,结合高校化学分析实验样品的理化性质,井通过铁矿石样品、水泥样品和开放设计性实验项目中样品的消解,将微波消解技术引入到化学分析实验中,并取得了良好的教学效果.
现代教育理论指导下,充分发挥现代信息先进实验手段优势,深化高等院校教育改革,结合本院科研特色和化学实验教学特点,打破传统验证型、演示型实验模式,引导学生开展研究性学习和创造性实验研究.提出化学实验教学中培养创新能力的途径和方法,造就具有创新能力的人才.
"仪器分析实验"是化学类专业本科生的必修基础课.本文结合笔者多年的教学实践,从优化教师队伍、重视基础理论讲授、加强学生在实验过程中的自主性、加强实验内容的实用性,提高学生学习兴趣和和重视复杂样品分析,引入样品前处理教学环节等多个方面对如何提升"仪器分析实验"课程教学质量进行了探讨.
X-ray absorption spectroscopy (XAS) is a unique and powerful technique for probing local structures which doesnt require long-range order materials.
Novel Pd/Cu catalyzed chemo-selective N-dealkylation / aerobic oxidative carbonylations to access amides have been developed.
Pd nanoparticles would formed from Pd(dba)2, which process would promoted by halide ion.The results was confirmed via XAS (X-ray absorption spectra) and TEM.XANES (X-ray absorption near edge structure
氧气参与的氧化反应在生物及化学领域扮演着重要角色,而铜元素广泛存在于生物酶氧化系统中承担氧气活化的作用,其氧化物种结构及氧化活化机制备受大家关注.各种配体的引入有效地帮助科学家们表征结构[2]、研究机理[3]、提高反应效率[4],然而在金属盐前体中常常包含的卤素配体作用[5]往往被忽略.我们运用在线红外技术、X-射线吸收谱研究了在TMEDA存在下铜(Ⅰ)空气氧化形成铜(Ⅱ)过程,揭示了卤素效应在铜
