Editorial 2006     
Dear Authors and Readers, The year 2005 was a specially remarkable year filled with much excitement, success, joy and sadness. The new format of the Journal proved to meet everybody's satisfaction. It is much easier to read, and the figures and tables are better positioned as there is more space to accommodate them. Not only did we change the appearance, but we have restructured the leading body of the Journal reorganizing the former Editorial Board and assigning Associate Editors according to main subject areas. With this solution proved to be a much more operational and practical one, and contributed to the increase of the scientific level of the Journal. It is a commonplace, that we live in a more and more specialised world. This trend is palpable in thermal analysis and we can experience it as we receive submissions dealing with very specialised topics. In order to strengthen our peer-review system, we hoped that the decision to divide the Associate Editors into main subject areas, will assist them in their work to establish and build a network of support reviewers from that particular field. After a year we can already see the result of this effort and we are very happy to look at the longer-than-ever list of reviewers we acknowledge for their scientific support (find the list of names on the next pages). Here I need to complement you all, as I am convinced that your enthusiastic and conscientious work is the foundation of our success, as it is reflected in the Impact Factor 2004 reaching the unprecedented height of 1.478 compared to 1.094 for 2003. Last but not least the novelty of 2005 was the introduction of the 'Online First' section on the electronic site of JTAC. We have fought for the opportunity to provide better service to our authors in terms of through-over-time for long and this solution finally offered the possibility to achieve it. It was a jubilation when we could publish the first papers in the 'Online First' section at the first time, and we felt that the most appropriate way to share our happiness is to publish the papers of the already finalized 'Celebration Issue' that was a surprise gift to us celebrating the 36th anniversary of the Journal with not less than 36 outstanding communications from the most prestigious scientists. I owe a special thanks to my long time friend and colleague Prof. Shmuel Yariv organising this Issue - this very moving gift - and for the excellence how he executed the collection and preparation of the papers. Last, but not least I need to express my sincere gratitude to all of those contributed with their high standard work to this December issue. We would like to acknowledge all those who had been working with us in the past years, and now giving space to new members in the line of Regional and Associate Editors. Special thanks to Prof. Gavrichev, Prof. Ray and Prof. Walter, Regional Editors, furthermore to Dr. Emmerich, Prof. Jones and Prof. Beezer, Associate Editors for their valuable work, and support. At the same time we have the pleasure to welcome the new Regional Editors: Prof. T. Usacheva for Russia, Prof. P. Thomas and Prof. D. Bessiéres for English and French speaking teritorries respectively. Our new Associate Editors are: Prof. G. Pokol, Prof. S. C. Mojumdar, Prof. E. Boldyreva and Prof. P. Budrugeac. I would like to provide a forum for new ideas and here I would like to call on to all Editors to contribute to this initiation. I am planning to write a mid-year editorial where we would share these new ideas, i.e. the issue of 'Short Communications' and similar topics of wide interest. This year was just as tragic as it was sucessful in losing many of our colleagues.We could hardly recover from the news of the sudden death of Prof. M. Richardson, Prof. Maria Kurzawa and our close friend and Associate Editor Prof. Lisardo Nuñez Reguiera when we had to say our final good bye to our beloved teacher, a world wide acknowledged scientist and inventor Prof. F. Paulik. Finally, I would like to wish a prosperous new year, health and success in every aspect of your life to all of you.  相似文献

Prof. Doug Ruthven and Prof. Jörg Kärger are two giants in the field of zeolite science and engineering. Over their academic careers encompassing almost forty years each, they have contributed significantly to the advancement of fundamental understanding of adsorption and diffusion in zeolites as well as their industrial applications. The author, in the beginning of his academic career, had an opportunity to spend two years as a post-doctoral fellow in Prof. Ruthven’s laboratory at the University of New Brunswick (1975–1977). This experience actually motivated me to spend my academic career in working in the field of zeolite adsorption and diffusion. Nearly thirty years later, I spent a year as a Gast Mercator Professor at the University of Leipzig in the laboratory of Prof. Kärger (2005–2006). These two opportunities at two different ends of my academic career provided me with unique perspectives to reflect on the important contributions made by Professors Ruthven and Kärger to the field of zeolite science and technology. This article summarizes my personal perspectives on the breadth and depth of their contributions.  相似文献

Prof. H. A. Laitinen (Urbana):We have used double layer capacity measurements to measure adsorption as a function of time during the life of slowly forming mercury drops. For many substances that are not extremely surface active, so that the solution concentration is 1 to 10 mM, the double layer capacity per unit area is essentially constant during the time interval of 5 to 15 sec of drop life. It appears, therefore, that adsorption equilibrium has essentially been attained during the later portions of drop life.Prof. P. Delahay:We have also used a similar method of following the differential capacity during drop life. I would agree that one can achieve conditions for which adsorption equilibrium with respect to bulk concentration is practically reached (high enough concentration and long drop time). But this is quite often not the case (drop time of 3–4 sec in polarography).Mr. G.C. Whitnack (China Lake, U.S.A.);In determination of nitrate esters in presence of phthalate esters we have observed considerable dropping of current height of nitrate ester wave before start of phthalate ester wave. Is this due to an adsorption process occurring at the DME?Prof. P. Delahay:It might well be, but I would hesitate to comment any further on this point because more information would be required. You probably have quite a complicated situation. Perhaps we can discuss the matter later?Prof. Dr. H. Fischer (Ettingen):Ich möchte hinzufügen, class es Fälle geben kann, in denen mcht allem der Blockierungseffekt don Grenzstrom verringert, sondern eine Veränderung des Diffusionsfilmes durch Sekundärreaktion des Inhibitors. Dies ist z.B. bei der Abscheidung von Wasserstoff an einer festen Elektrode (Fe) der Fall, wenn der Inhibitor sich spaltet in eine schwerlösliche Verbindung und ein Proton (RNH+ → [RN] + H+). Dies beobachtet man z.B, bei den Kationen von heterozyklischen Aminen (Acridin). Offentlich bildet sich eine diffusionshindernde Barriere aus.Prof. P. Delahay:The case of the hydrogen electrode is complicated, and I shall attempt to answer your question only in the case of an ideally smooth electrode. Then, diffusion toward the electrode (partially covered with an adsorbed substance) is little affected by adsorption because the size of “the holes” in the film is very small in comparison with the diffusion layer thickness. Of course, there is no diffusion where there is complete blocking.Prof. B. Breyer (Sydney):The importance of the chemical nature of the film adsorbed at the interface, which has been mentioned by Prof. delahay, seems to me to play a major part in the type of processes discussed. Thus it must be kept in mind that complex formation between the diachargeable ion and the adsorbed film might occur (cf. e.g. heyrovsky? and matyas, 1941). The fact that T1+ ion is little influenced by the presence of an adsorbed film at the electrode solution interface could then be partly explained by the notoriously low co-ordination tendency of that ion.Prof. P. Delahay:The difficulty involved in the “blocking” of the limiting current for thallium is due, I think, to the small size of this ion (large diffusion coefficient of Tl+ in comparison with other ions). Of course, complex ions can be relatively very bulky and this enhances “blocking”.Prof. E. Lange (Erlangen):I agree with prof. delahay that it is very important to investigate the connections between the adsorption and electrode reaction.This is easy for a steady state, e.g., each heterogeneous reaction between two phases that is accompanied by a transfer of ions or electrons, i.e. of electrical charges, from one phase to the other. In such a case, the Galvani tension does not change and the transfer between the two phases must be compensated by a corresponding transfer of charges within the phases.But in the non-steady state, also, an adsorption process may behave as an “electrode reaction” for instance, even an adsorption of a dipole molecule may cause a “transfer of charge” accompanied by a corresponding change of the Galvani tension. In this manner, it seems to me that for the non-steady state it is necessary to define precisely what one means by “electrode reaction”.Prof. P. Delahay:I entirely agree with Prof. i.ange about the necessity of clear definitions. I think that the fact that a steady state with respect to diffusion of the reductible or oxidizable substance has not been reached is not too serious because this scarcely affects the Galvani potential (large excess of supporting electrolyte).Variations in the amount of adsorbed organic substances indeed affect the Galvani potential (dipole orientation), but this effect is included in the dependence of the rate constant ks (at the standard potential) on the electrode coverage.Prof. N. Tanaka (Sendai, Japan).I am very grateful to Prof. delahay for his beautiful work on adsorption kinetics. I should like to make one comment in connection with the rotated dropping mercury electrode. The relation between log i and log t on the current — time curve was found to be 0.5 only in the absence of the surface-active substance. In the presence of surface-active substance, the slope of log i vs. log t changed at a certain point of the current — time curve. This can be explained when the slow adsorption of the surface-active substance on the surface of the electrode is taken into consideration.Prof. P. Delahay:Even for stirred solutions, adsorption equilibrium is not reached very rapidly. A simple calculation based on a model of the Nernst diffusion layer shows that perhaps 1–5 sec are required. Your conclusion is, therefore, quite correct.Prof. W. Kemula (Warsaw):We have recently published that, in several cases, the addition of extremely small concentrations of organic surface-active substances provokes at first a rise of the diffusion current, this current then being suppressed by additional quantities of the substance.  相似文献

This article has been retracted at the request of the Editors-in-Chief. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). REASON: Considerable concern was raised about the research purportedly conducted at Sri Venkateswara University, India with the alleged involvement of Prof. P. Chiranjeevi. Questions were raised as to the volume of publications, the actual capacity (equipment, orientation and chemicals) of the laboratory in which Prof. Chiranjeevi worked, the validity of certain of the research data identified in the articles, the fact that a number of papers appear to have been plagiarized from other previously published papers, and some aspects of authorship. Professor Chiranjeevi was given the opportunity to respond to these allegations. Thereafter, a committee was constituted by the University to look into these allegations. Based on the enquiry committee report, we have been informed by the head of the Department of Chemistry at Sri Venkateswara University that the university authorities have taken disciplinary action against Prof. Chiranjeevi, as the university considers that there are grounds for such action. Therefore, based on the results of this investigation, the Editor is retracting this article.  相似文献

Preface     
The fifth CBRATEC (V Congresso Brasileiro de Análise Térmica e Calorimetria) conference was held in April 02–05, 2006 in Poços de Caldas, MG. One third of the 370 participants was graduates and Ph.D. students well representing the continuous interest in thermal analysis among Brazilian researchers. The structure of conference was characteristic and refreshing, since every morning one of the leading Brazil thermoanalysts held an opened teaching course especially for the representatives of the young generation. After then plenary lecturers and keynote speakers (J. Rouquerol, Cs. Novák, D. Burlett, M. Suchyta and A. Riga) occupied the podium. The afternoon sessions consisted of mainly short lectures and poster exhibitions; both provided excellent possibility for the Ph.D. students to introduce their scientific work. The scope of conference covered practically all aspects of thermal analysis. Since 1998, when the first CBRATEC conference was held, the participation of young scientists and the organization of teaching courses played essential role for them. As an effort to increase international experiences, the universities pay continuous attention to foreign language education (first of all English), so the communication between the invited international researchers, the representatives of the instrument companies and the domestic conference attendants became much more efficient in recent years. During the conference the new Executive Committee was elected. Prof. Valter José Fernandes Junior was elected as President of ABRATEC supported by the members of the Executive (Jivaldo do Rosário Matos (Vice-President), Massao Ionashiro, Lázaro Moscardini D’Assunção, Clóvis Augusto Ribeiro, Elias Yuki Ionashiro, Carlos Isidoro Braga, Manoel Luiz Cunha Rodrigues, Rodrigo Maciel). In recognition of his continuous cooperation for the development of thermoanalytical researches in Brazil and its scientific divulgation in Thermal Analysis, the ‘Special Award’ of ABRATEC (Brazilian Association for Thermal Analysis and Calorimetry) was presented to Prof. Csaba Novák. For their outstanding achievements in developing the international relation of ABRATEC, Honourable Membership of the Thermoanalytical Sub-Branch of the Hungarian Chemical Society was presented to Prof. Jivaldo do Rosário Matos, Massao Ionashiro, Prof. Valter José Fernandes Junior and Prof. Éder Tadeu Gomes Cavalheiro at the opening ceremony. At last but not least, according to the decision of ICTAC Council during the 13th ICTAC (2004, Chia Laguna, Italy) Brazil was elected as the host of ICTAC 14 in 2008. The Brazilian thermoanalytical community feels extremely honored to be entrusted with the organization of the 14thICTAC Conference that will take place in São Pedro, SP, in September 14–19, 2008, where the scientists, researchers and students, who are acting in the field of thermal analysis and calorimetry are cordially invited. The link to the conference site is www.ictac14.com.br.  相似文献
