培养创新型人才要重视基础 抓好“五基”教学

自20世纪80年代以来,化学类专业教学改革迈出了较大的步伐,并正在逐步深入,培养创新型人才已成为新世纪教学改革的中心议题.众所周知,重视"三基"(基础理论、基础知识和基本技能)是我国高等教育的优良传统,实践证明,"三基"教学造就了大批"服务型人才",从培养"创新型人才"的要求来说,我们认为应强调"五基"(即在"三基"的基础上,加入"基本思维和基本能力")使我们在传统的基础上有所前进.     

浅议工科化学教材的习题设置

实现专业对口教育向素质教育的转变，是当前高等教育改革的重点。素质教育不是对教育的分类，而是一种指导思想，一种教育观，它强调的是一种基础，一种素养，是一种做人和做学问的功底。以此来反思我国以往的高等教育，会发现诸多与之不相适应之处。本文拟从素质教育出发...     

应用化学的历史及其意义

应用化学的概念源于１９ 世纪中叶，１９１９ 年ＩＵＰＡＣ的成立确立了其基本含义。应用化学作为培养化学工程人才的高等教育专业的名称出现在日本和我国，虽曾一度转化为化学工程系，但随着时代对新产品、新材料、新能源的要求不断提高和扩展，应用化学又成为我国高等教育的一个热门专业。本文探讨了应用化学的发展过程和特点。

“三维”立体化保障体系为化学学科教书育人做好核心支撑——吉林大学化学学院人才培养保障工作实践探索

目前,我国高等教育发展已经进入“深水区”和“无人区”,校、院层面围绕人才培养建立的管理机制、服务机制需要广大教育工作者的探索与实践。吉林大学化学学院充分利用职称评聘、教师能力发展、学生活动、教学改革和课程建设等方面的政策导向,健全奖励激励制度,加强配套经费支持,探索构筑了以教师和学生为主体,涉及教学、管理和服务的“三维”立体化保障体系,有效地促进和保障了学院高质量拔尖创新人才培养。     

微量元素与心血管病

心血管病是当前各国人群的主要死亡原因之一。1998年我国心脏病居全国居民病伤死亡的第三位（城市）和第四位（农村）、其死亡率逐年增加，我国每年死于心脏病的人数约为273万人。最常见的心血管疾病分为：     

师范院校物理化学课程虚拟教研室建设的探索与实践

加强基层教学组织建设,构建立德树人体系,是推动我国高等教育高质量发展的重要保障。虚拟教研室是信息化时代高校基层教学组织的探索,是高等教育数字化发展战略的重要组成部分。本文回顾了师范院校物理化学课程虚拟教研室试点建设一年多时间里,利用信息化智慧教学手段开展线上线下、虚实结合的教学研究活动及课堂教学实践,并总结了虚拟教研室在国际化教学团队领域的探索,以及坚持师范引领面向中学教师开展教学研究等特色活动,进一步以华南师范大学物理化学课程建设为例,突出虚拟教研室共建共享在促进高校基层教学组织建设方面的贡献。     

微量元素与癫痫(2)

癫痫是神经系统疾病中仅次于脑血管病的第二大病症。我国目前约有850万癫痫患者,每年新发40万人,给个人、家庭和社会带来了严重的负面影响。从癫痫流行病学、危险因素、微量元素失衡、微量元素再分布及微量元素脑影像学五个方面阐述了微量元素与癫痫的关系。     

化“材”为“筑”

Chemistry is a central, practical and creative discipline. The development of chemistry plays an important role in the progress of science and society, as well as the improvement of the quality of human life. This paper introduces the chemical knowledge of stone, concrete, glass and other inorganic nonmetallic building materials by the anthropomorphically story. Taking nanomaterials as an example, the prospect of building materials development in the future is put forward.     

"Alpha"-, "beta"- and "delta"-anhydrodigitoxigenin

The syntheses of 3β-hydroxy-5β-carda-14, 20:22-dienolide (= «β»-anhydro-), 3β-hydroxy-5β-carda-8:14, 20:22-dienolide (= «α»-anhydro-) and «δ»-anhydro-digitoxigenin (= probably 3β-hydroxy-5β, 14β-carda-8, 20:22-dienolide) by the best ways known to date, have been described. «δ»-Anhydro-digitoxigenin represents the thermodynamically most stable isomer. In this isomer the double bond in position 8 is unaffected by hydrogenation with Pt in acetic acid; with perbenzoic acid an epoxide results from which, on hydrogenation, the double bond can be regenerated in its original position. Analogous reactions are known to occur in the 8:14-epoxides.     

Making "wheels" and "cubes" from triangles

[Mn(IV)Mn(II)3] triangular units directed by the presence of tripodal alcohols self-assemble in the presence of azide and acetate ligands to form either a [Mn24] "wheel" or a [Mn32] "cube".     

"Turn-on" fluorescent sensing with "reactive" probes

Chemical probes are valuable tools for the investigation of biochemical processes, diagnosis of disease markers, detection of hazardous compounds, and other purposes. Therefore, the development of chemical probes continues to grow through various approaches with different disciplines and design strategies. Fluorescent probes have received much attention because they are sensitive and easy-to-operate, in general. To realize desired selectivity toward a given analyte, the recognition site of a fluorescent probe is designed in such a way to maximize the binding interactions, usually through weak molecular forces such as hydrogen bonding, toward the analyte over other competing ones. In addition to such a supramolecular approach, the development of fluorescent probes that sense analytes through chemical reactions has witnessed its usefulness for achieving high selectivity, in many cases, superior to that obtainable by the supramolecular approach. Creative incorporations of the reactive groups to latent fluorophores have provided novel chemical probes for various analytes. In this feature article, we overview the recent progress in the development of turn-on fluorescent probes that are operating through chemical reactions triggered by target analytes. Various chemical reactions have been implemented in the development of many reactive probes with very high selectivity and sensitivity toward target analytes. A major emphasis has been focused on the type of chemical reactions utilized, with the hope that further explorations can be made with new chemical reactions to develop reactive probes useful for various applications.
