我于 1 95 6年考取南京大学研究生 ,从师戴安邦教授。他指定我参加“硅酸及其盐的研究”课题小组。 1 960年研究生毕业后 ,留在南京大学化学系工作。在教学上 ,我是戴先生的助教 ;在科研上 ,我是他的主要助手和他的研究生的副导师。在以后 ,即使我本人晋升了副、正教授 ,并且自己也招了研究生 ,仍一直在他的指导和关怀下工作着。从 1 95 6年 8月第一次见到先生 ,到 1 999年 4月他逝世 ,我和他有 40多年的朝夕相处 ,亲身领受到他在教学、科研、做人等各方面的言传身教 ,他为我们树立了光彩永存的榜样。1 治学态度戴先生的治学态度可用“勤奋… 相似文献

Note from the Editor: It is with great pleasure and enthusiasm that I introduce this essay which accompanies the publication of the fourth segment of the Tetsuo Nozoe Autograph Books. In the conceptualization stages of this project—which shall appear in 15 consecutive issues of The Chemical Record as well as have a significant internet presence—I proposed to my colleagues Eva Wille and Brian Johnson that each segment be accompanied with a specially invited essay or perspective. This proposal was immediately and enthusiastically accepted. To both celebrate the life and warmth of Tetsuo Nozoe, I can hardly imagine a more appropriate essay than one written by two of his grandchildren and one of his own children! I thank the Masamune Family for their touching contribution to this project. The Nozoe Autograph Books and all the accompanying essays, including this essay, are open access for at least a three‐year period at: http://www.tcr.wiley‐vch.de/nozoe . Jeffrey I.

Ab initio molecular orbital theory is used to study carbon-beryllium binding in the lowest singlet and triplet states of CH2Be. When electron correlation is included, both singlet and triplet states are significantly bound relative to the ground states of CH2 and Be fragments. 相似文献

The path of chemistry in the future will be determined both by its participation in solving large-scale societal problems and by its generation of new ideas through basic research. This article sketches four of the areas of societal “pull” in which chemistry will play a role in solving applied problems—national security, health care, the environment, and energy—and four areas in which basic research will be especially fruitful—materials chemistry, biological chemistry, computational chemistry, and chemistry exploring the limits of size and speed in chemical phenomena. 相似文献

Atmospheric fallout of7Be was measured over a 2 year period (January 1995–January 1997) at Damascus city (33 No, 727 m above sea level). The annual total deposition of7Be was found to be 420 and 634 Bq·m−2 for 1995 and 1996, respectively, reflecting a Mediterranean climate where two well recognized periods are dominant (wet and
dry). The depositions in the wet periods were 303 Bq·m−2 and 517 Bq·m−2 for 1995 and 1996, respectively, while unexpected equal deposition rates in the two dry periods were found to be about 117
Bq·m−2. In addition, monthly deposition rate of7Be showed a maxima in February in 1995 and January for 1996. Moreover, a comparison has been set for our measurements and
other data obtained at different locations in the world. 相似文献

In the course of preparing the Special Issue of Macromolecular Rapid Communications on High‐Throughput and Combinatorial Methods in Polymer Science, the question arose of how a global company such as Bayer coordinates its activities in high‐throughput experimentation (HTE). Being usually confronted with research results in the form of publications as in this issue, Macromolecular Rapid Communications was interested in the earlier stages of management and development, and wished to provide a look behind the scenes. Georg Wiessmeier made this possible by taking the time to answer a lot of questions with respect to the Bayer way of pursuing HTE, as well as the general development and future perspectives of this technology. 相似文献

Near-surface air concentrations of7Be and its deposition rates were measured in the atmosphere in Bratislava from 1977 to 1994. Late spring and summer maxima were observed in the near-surface air concentrations on an annual basis. Using measured deposition rates and the calculated average tropospheric content of7Be atoms, their mean tropospheric residence time (27–48 days) was determined. An anticorrelation between the measured7Be concentration and the sunspot number with correlation factor of 0.55 was observed. 相似文献
