三十而立 三世其昌——恭贺《化学教育》30周年刊庆

回顾过去,记忆犹新。“文化大革命”使得教育战线遭到严重摧残,当时,几乎所有的教学杂志都停刊了,粉碎“四人帮”后,教育迎来了春天。在理科教学期刊方面,北京师范大学率先创办了《中学理科教学》,发表有关数学、物理、化学等方面的文章,着力介绍新编教材等情况。后随着《数学通报》等学科类刊物复刊或创办,《中学理科教学》停刊了。在改革开放的春天,北京师范大学陈光旭教授等人在中国化学会的领导下,积极筹办化学教育类期刊,于1979年5月开始组稿等工作,《化学教育》在1980年4月创刊了。

国内化学教育领域调查研究的内容分析与品质考察

选取化学教育领域核心期刊《化学教育》和《化学教学》2011-2016年的180篇调查研究类文献为样本,分析了研究的现状和趋势,并运用“调查类文献品质考察工具”对调查类文献品质进行了考察。研究发现,调查类研究数量呈下降趋势;研究主题以化学学习、教师教育、化学教学为主;调查对象主要是中学生和在职教师;作者群体约半数来自高等学校。研究品质方面,虽然研究品质逐年提高,但整体研究品质仍不容乐观,主要问题在于缺乏信度和效度的直接证据,数据分析处理方式单一,以及文献探讨不足。

化学学科的新视角及其在化学教育中的反映

传统化学以研究变化,关注变化前后的结果而著称。化学与其他学科,特别是生命科学的相互渗透使得化学的动态特征更加突出,化学学科格局也因之发生了变化。因此,化学需要新认识。     

Dual zinc catalysts for L‐lactide polymerization and reaction of CO2 with cyclohexene oxide

A series of zinc complexes, [ L ^X ZnEt] ( 1–5 ) and [ L ^X Zn ₂ (OAc) ₃ ] (6–9) , associated with NNO‐tridentate Schiff base ligands (2‐(((2‐((cyclohexyl[methyl]amino)methyl)phenyl)imino)methyl)phenolate (CAP) derivatives), were synthesized, and their activity toward ring‐opening polymerization (ROP) of L‐lactide (LA) and the reaction of CO₂ with cyclohexene oxide were also investigated. All of [ L ^X ZnEt] revealed excellent catalytic activity to ring‐opening polymerization (ROP) of LA in the presence of benzyl alcohol. Among them, [ L ^H ZnEt] (1) showed the highest activity with 82% conversation within 45 s. In contrast, [L ^X Zn ₂ (OAc) ₃ ] (6–9) were inactive in ROP of L‐lactide. In addition, all of these Zn complexes demonstrated moderate activity in the reaction of CO₂ with cyclohexene oxide in the presence of Bu₄NCl.     

Exploring recent developments on 1,2,4-triazole: Synthesis and biological applications

Triazoles are nitrogen-bearing heterocycles. In the last few decades, researchers have focused on fused heterocycles, as they have better pharmacological effect compared to triazoles alone. Among the two isomers of triazole, this article aims to explore the work carried out on 1,2,4-triazole and N-bridged heterocycles derived from 1,2,4-triazole in last 18 years, highlight different synthetic pathways, and present a brief summary of the different biological activities possessed by 1,2,4-triazole derivatives. The information collected in this article is expected to help researchers to discover novel therapeutic agents for better applications in the field of pharmaceutical science.     

Novel arylpyridine‐based 1,3,4‐oxadiazoles: Synthesis,antibacterial, and anti‐inflammatory evaluation

In view of developing novel bioactive compounds, a series of 2‐(5‐[2‐methyl‐6‐arylpyridin‐3‐yl]‐1,3,4‐oxadiazol‐2‐ylthio)‐1‐arylethanones (6a–n) were designed and synthesized in good yield. Novel compounds were evaluated for their antibacterial and anti‐inflammatory activities. All synthesized compounds were screened for their antibacterial activity against Staphylococcus aureus, Bascillus subtilis, Eschericia coli, and Pseudomonas aeruginosa strains. Compounds 6a , 6b , 6c , 6h , and 6i displayed the highest antibacterial activity with minimal inhibitory concentration (MIC) values ranging from 6.25–12.5 μg/mL in comparison with the standard Ciprofloxacin. The results of anti‐inflammatory activity of carrageenan‐induced footpad edema assay indicated that tested compounds exhibited remarkable anti‐inflammatory activity with percentage of inhibition of 63.9–70.1% (potency 96.8–106.20% of indomethacin activity) after 3 hr. Particularly, 6c – e and 6j – l were found to be excellent inhibitors of inflammation, with potential higher than that of the standard, Indomethacin.     

Synthesis of symmetrically and unsymmetrically substituted S,S-dialkyl phosphonodithioates

Herein, we report the synthesis of a range of S,S-dialkyl phosphonodithioates. Symmetrically substituted analogues were readily prepared from the corresponding phosphonic dichlorides in good to moderate yields, while unsymmetrically substituted variants were obtained by a sequential alkylation-deprotection-alkylation strategy.     

Chemistry of the Positron and of Positronium

In this progress report, the properties and behavior of the positron (“positive electron”, anti-electron) and of the positronium, a “hydrogen atom” containing a positron instead of a proton, are considered from the chemist's viewpoint. Examples are given to demonstrate the development of positronium chemistry, in aqueous solution and in the gaseous, liquid, and solid phases, with its problems and possibilities.     

Methods and Applications of Quantum Chemistry. Part I: Physical and Mathematical Basis

After an introduction to the fundamental concepts of quantum mechanics it is shown how to describe a chemical system in the language of theoretical physics. The equations which one obtains can not, in general, be solved in closed form. Approximate numerical methods that furnish sufficiently accurate solutions for many problems of interest are, however, available. The most important of these are presented briefly, and are given physically visualizable interpretations as far as this is possible. Special attention is devoted to more modern methods of quantum chemistry, to the basis assumptions underlying them, their scope, and their limitations. Treatment of the theory of the chemical bond is reserved for Part II.
