In an interview with Benjamin List, winner of the 2021 Nobel Prize in Chemistry, members of the Young Chemists’ Network (JCF) of the German Chemical Society (GDCh) asked him about his science, his career, and the academic system. Benjamin List, Director at the Max-Planck-Institut für Kohlenforschung in Germany, was awarded the Nobel Prize together with David W. C. MacMillan (Princeton University, USA) for the development of asymmetric organocatalysis. After studying chemistry at the Free University of Berlin, he received his doctorate from Goethe University in Frankfurt. He discovered the amino acid proline to be an efficient catalyst and thus co-founded the field of organocatalysis. In 2016, he received the Gottfried Wilhelm Leibniz Prize, which is considered the most important research award in Germany. 相似文献

The progress of macrolide chemistry and biochemistry over the past several years has indeed been remarkable. This review attempts to cover the important contributions which have been made in the fields of structural and synthetic chemistry as well as in the biosynthesis and mode of antimicrobial activity of the “polyoxo” macrolide antibiotics. Emphasis has been placed on the recent synthetic achievements in this field. 相似文献

The emerging field of supramolecular chemistry, which involves “chemistry beyond the molecule” and which emphasizes non-covalent intermolecular bonding and structures, also provides an intellectual basis for a new vision of photochemistry, namely supramolecular photochemistry. Supramolecular photochemistry embraces not only the principles of supramolecular chemistry, but also the principles of supramolecular physics which deal with the influence of static and fluctuating electric and magnetic fields on photochemical reactions. Thus, the combination of intermolecular forces, sometimes quite weak individually but strong cooperatively, and electrical and magnetic forces “beyond the molecule” provide exciting opportunities to control the course of new photochemical reactions and to investigate important examplar reactions in novel ways. 相似文献

Advances in instrumentation and technology now provide the ability to perform many quantitative determinations in the field. Additionally, the potential for sample degradation and analyte decomposition make it necessary to determine certain analytes (e.g., dissolved oxygen) in the field when conducting environmental analyses. Unfortunately, field environmental—analytical chemistry is not a substantial portion of the analytical chemistry curriculum at many institutions. Students in lower-level analytical chemistry courses are often non-chemistry science majors, particularly at institutions with small chemistry departments. We report here on an experiment in which field environmental-analytical chemistry is introduced in the quantitative analysis laboratory. In the context of a water quality assessment of a local river, students determine temperature, pH, ORP, nitrate nitrogen, and ammonia nitrogen at several points in the river. The experimental objective is to determine the potential effects local agricultural practices and treated wastewater discharge may be having on the water composition. The pedagogical objective is to expose these students to the difficulties involved in making analytical determinations in unfamiliar and/or disruptive settings. 相似文献

Among recent progress in the field of macromolecular chemistry, of considerable interest has been the synthesis of α, ω-ordifunctional polymers. These polymers, called “telechelic” polymers, are interesting because many reactions are possible on their functional end-groups: 相似文献

The objective of this paper is to examine the challenges and opportunities in high throughput screening of atomic scale chemistry via a technique known as atom probe tomography. While there are numerous methods that exist in the field of throughput screening, even at the nanoscale, most of the effort is on screening properties , rather than chemistry and/or structure. In this overview, we discuss the role atom probe tomography can have as a high throughput screening tool of atomic scale chemistry. Particular emphasis on the study of organic/ biological materials is given along with the needs and challenges to make atom probe tomography more widespread in the field of combinatorial chemistry. 相似文献

We describe the field of supramolecular chemistry as a consequence of the progress of chemistry from its premises to recent achievements. Supramolecular chemistry has been claimed to be an emergent field of research taking its roots in chemistry. According to the definitions of emergences related to hierarchy or more recently to scope, supramolecular chemistry is shown to have bottom-up or top-down emergences. The bottom-up emergence, directly related to hierarchy by definition, opens up the world of nanochemistry and nanomaterials while the top-down one, attributable to scope due to the implication of supramolecular chemistry in other fields of research, open the world of supramolecular biochemistry. Both emergences lead supramolecular chemistry to become a supramolecular science. Combining supramolecular chemistry with biology opens new direction in the study of life and it origin. 相似文献

A novel technique enabling selective bead trapping in microfluidic devices without the use of physical barriers is presented in this paper. It is a fast, convenient and simple method, involving microcontact printing and self-assembly, that can be applied to silicon, quartz or plastic substrates. In the first step, channels are etched in the substrate. The surface chemistry of the internal walls of the channels is then modified by microcontact printing. The chip is submerged in a bead slurry where beads self-assemble based on surface chemistry and immobilize on the internal walls of the channels. Silicon channels (100 microm wide and 50 microm deep) have been covered with monolayers of streptavidin-, amino- and hydroxy-functionalized microspheres and resulted in good surface coverage of beads on the channel walls. A high-resolution pattern of lines of self-assembled streptavidin beads, as narrow as 5 microm, has also been generated on the bottom of a 500 microm wide and 50 microm deep channel. Flow tests were performed in sealed channels with the different immobilized beads to confirm that the immobilized beads could withstand the forces generated by water flowing in the channels. The presented results indicate that single beads can be precisely positioned within microfluidic devices based on self-assembly which is useful as screening and analysis tools within the field of biochemistry and organic chemistry. 相似文献

简述了分析化学的发展历史。分析化学的"昨天",从基于物理化学的溶液理论,以目视可见为工具的"化学分析",进入以物理方法为基础的仪器分析,因此有人提出"化学正在走出分析化学";分析化学的"今天",因为它的主体任务是解决物质的分子原子结构和成分,所以又回归化学领域;对分析化学的"明天"寄厚望,分析化学走出历来仅仅以"为他人报告提供数据"的技术支持者的角色,成为"实际问题解决者",利用分析化学中综合分析的"剖析技术",为新产品开发创制的"反工艺研究"做出独特的贡献。 相似文献

This paper emphasizes the wide possibilities open to organometallic chemistry by the bottom-up approach for nanosciences. In this new field of research, organometallic chemistry and coordination chemistry are in position to play a very important role in the development of nanomaterials. At first, organometallic and coordination chemistries will be the mothers of plenty of nanotools, which are the elemental bricks of nanosciences. The nanomaterials are obtained from them either by inclusion in a matrix (Nanocomposites) or by grafting methods (grafted nanomaterials). However, the most exciting field of investigation are the nanostructured hybrid materials which permit to open new fields of investigation such as self-organization of organic moieties or the coordination chemistry in the solid. Some examples are given. Moreover, the organometallic chemistry performed on both the framework and the pores of the nanoporous solids obtained by sol-gel chemistry in the presence of structure directing agents is opening the way to smart materials. These materials will have the ability to couple interactively two different properties. 相似文献

Nowadays, the environment protection and the personal health and safety are given more consideration in the field of chemistry, thus resulting in an increased number of published researches about how to work according to green instructions, to follow up the recommendations of environmental agencies and to obtain better clean handling of chemistry. In this review, green chemistry definition, importance, principles, and some recent applications in the field of green chemistry were discussed. In addition, the review summarizes the evolution of green analytical chemistry (GAC) with its specific principles and how to make the analytical process more environmentally benign with special emphasis on recent applications of GAC. Moreover, the green chromatography, its methods, and some of its applications were outlined. Finally, different techniques available up till now for the assessment of greening of the methods were also presented. 相似文献
