量子点电化学发光研究进展及展望

电化学发光因具有低背景、高灵敏度的优势已成为当前最先进的体外诊断技术之一.以三联吡啶钌为代表的分子型电化学发光体系虽然实现了商业化应用,但其光学性质已无法满足电化学发光分析的发展需求.量子点作为新一代的理想发光材料在电化学发光领域表现出巨大的应用前景.然而,由于对量子点电化学发光的过程和机理研究尚不充分,目前量子点电化学发光的各项性能均有待提升.本文聚焦于量子点电化学发光领域的关键科学问题,在总结该领域重要研究进展的基础上,指出光谱学、合成化学及电分析化学等多领域学科交叉是未来量子点电化学发光研究的重要发展方向.

Development of electrochemistry in Serbia-challenges and perspectives

In this review, the development of electrochemistry in Serbia is presented, with an accent on historical moments from the beginning up to contemporary research directions. The pioneer in the establishment of electrochemical science was Professor Panta S. Tutundzic, who was elected Assistant Professor in Physical Chemistry and Electrochemistry in 1925, when the Department of Technology, previously integrated within the Technical Faculty in Belgrade, was established as a separate department. From the time of Professor Tutundzic′s group to today, a community of many eminent researchers has been involved in electrochemistry development, creating the world-renowned Belgrade School of Electrochemistry. It was not actually a formal school of electrochemistry but rather a variety of research directions, and first of all people doing excellent electrochemical science recognized at the international level. As one of the members of the contemporary active electrochemistry community from Serbia, and successors of the Belgrade School of Electrochemistry, I have both the special honor and the responsibility of presenting the historical contribution of such outstanding and internationally recognized scientists in the most appropriate way. Having in mind that any school and research area is predominantly determined by human resources, I will focus on the great contribution of the most prominent electrochemists, from the founders up to those active today. The main research directions were and still are electrodeposition, electrochemical reaction kinetics, electrocatalysis, energy production and storage, and corrosion and corrosion protection.

     

Characterization of cobalt- and copper hexacyanoferrate-modified carbon film electrodes for redox-mediated biosensors

Cobalt and copper hexacyanoferrate films (CoHCF and CuHCF) were formed at carbon film electrodes by three different one-step processes: cycling the applied potential, application of a constant current, and chemically. All hexacyanoferrate films obtained were characterized electrochemically by cyclic voltammetry and electrochemical impedance spectroscopy. To evaluate their possible use as redox mediators for biosensors, they were applied to the determination of hydrogen peroxide in neutral phosphate buffer saline electrolyte. Chemically deposited CuHCF was found to be generally the most suitable as a mediator, although CoHCF made by potential cycling is the most useful when a very low detection limit is necessary.Dedicated to Professor George Horanyi on the occasion of his 70th birthday, in recognition of his outstanding contributions to electrochemistry.

Honda’s thermobalance

Kotaro Honda (2/23/1870–2/12/1954) graduated from the Department of Physics, Tokyo Imperial University in 1897. Between 1907 and 1911, he stayed in Europe, and spent the majority of his time at Göttingen University to study physical metallurgy under Professor Gustav Tammann. In 1911, he returned to Japan and was nominated professor of physics at Tohoku Imperial University, Sendai. An university-affiliated institute for research on iron and steel was established on a permanent basis in 1919, and the institute developed to the Research Institute for Iron, Steel, and Other Metals (RIISOM, KINKEN in Japanese) in 1922. Professor Honda served as the Director of the Institute until 1933. The RIISOM was reorganized as a national collaborative research institute named Institute for Materials Research in 2001. Professor Honda and his colleagues achieved distinguished research works of physical metallurgy, in which thermoanalytical techniques such as differential thermal analysis (DTA), thermodilatometry and thermomagnetometry were utilized effectively. Professor Honda also played an important role in the field of thermogravimetry (TG) by means of the first development of the thermobalance. In the present paper, Honda’s original thermobalance, various modifications carried out by his school, the commercialized Honda’s thermobalance and other related matters are briefly summarized.     

Gold polycarbonate microchannels for electrochemical applications

In this paper, we present gold-plating polycarbonate (PC) microchannels. The fabrication of the gold microfluidic channels is achieved by tuning the sequence of reagent insertion into milled and closed submillimeter PC system channels. The resulting gold surface can be utilized in many applications where the benefits of microfluidics, (bio)chemistry of surfaces, and electrochemistry can be combined. Here, we combine the advantages of electrochemistry with microfluidics by mixing the gold sensor with microfluidics. This approach differs from the classic one – the sensor will undergo modifications (e. g., shape and size) depending on the specific scientific problem and will be designed individually; hence its characteristics will be changed. Our goal in this work is to indicate new possibilities for combining two methodologies – electrochemistry and microfluidics. In our work, we emphasize that it confirms the validity of our chosen concept (proof-of-concept). In this work, we present one such application, the use of a gold microfluidic channel as a working electrode (WE). We describe the microchip‘s construction and electrochemical characterization, including the gold flow-through WE, the Ag/AgCl wire pseudo-reference, and the Pt auxiliary electrode. The measured current is the result of the flow through a rectangular duct of the gold microchannel electrode embedded in the four walls of the chip.     

On the effect of tungsten on CO oxidation at Pt electrodes

The co-catalytic effect of W on the oxidation of CO and methanol is investigated by using differential electrochemical mass spectrometry (DEMS). DEMS reveals that CO oxidation starts at 120 mV, overlapping with W oxidation. The action of W consists in shifting the pre-peak from 450 mV (as observed on pure Pt) to 200 mV. In this shifted pre-peak only 2% of the total adsorbed CO is oxidized independently from the W coverage, as compared to 10% on pure Pt. A correlation between the surface coverage of W as determined by XPS with the W oxidation peak charge in cyclic voltammetry suggests that the oxidation is a six-electron process.Dedicated to Prof. Wolf Vielstich on the occasion of his 80th birthday in recognition of his numerous contributions to interfacial electrochemistry.

Charge attachment–induced transport: toward new paradigms in solid state electrochemistry

Modern applications in solid state electrochemistry, e.g. in the field of energy storage and conversion, involve the transport of charge carriers through surfaces or interfaces as a key aspect. Many of the electrochemical concepts in fact originate from the field of liquid state electrochemistry. The transfer of concepts from the liquid to the solid state causes some problem which are addressed in this review. Topics covered include (i) electrode potentials and half-cell potentials, (ii) charge carrier blocking and dielectric breakdown, and (iii) activities versus particle densities. Many of these topics can be addressed by the charge attachment–induced transport technique developed in the authors group. The discussion involves modifying some of the paradigms we became acquainted to in the liquid state.
