The American Chemical Society&;#39;s Summer Schools in Nuclear and Radiochemistry

Summary Uses of radioisotopes and radiation in medicine, industry, agriculture are amongst the most beneficial applications of atomic energy for peaceful purposes. The International Atomic Energy Agency aims - in accordance with its statute - to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world. The various Technical Divisions of the Agency carry out this mandate and enhance, particularly through 'manpower development activities' the nuclear applications of radiation and isotopes. Staff members of the 'Industrial Applications and Chemistry Section' in the Department of Nuclear Sciences and Applications of the IAEA have supported more than 600 trainees per year for education in nuclear and radiochemistry through fellowships, training courses and workshops. Provision of printed material in various disciplines is supporting our educational efforts.

The United States Department of Energy funded program: Summer schools in nuclear and radio-chemistry

Following several national surveys that clearly indicated both a paucity of universities offering nuclear chemistry courses, and a severe shortage of personnel trained and educated in nuclear sciences, the US Department of Energy (DOE) agreed to fund a special summer program. This program would take 12 undergraduates on a competitive scholarship basis from across the nation, and provide them with an intensive 6 week course in the fundamentals of nuclear science. The first such course was taught in the summer of 1984 at San Jose State University in California, and has met each summer since that time. In this course, the students cover material equivalent to approximately 2 semester units of health physics and radiological safety, 3 semester units of lecture material on nuclear chemistry, radiochemistry, uses of radionuclides, and nuclear instrumentation, and 3 semester units of laboratory work in radiochemistry, radiation chemistry, and associated topics in nuclear science. A second course was opened in 1989, with the same curriculum and intent, and sited at the Brookhaven National Laboratory on Long Island, New York. With regard to intent, both courses are very successful, with a majority of persons going on to complete graduate degrees in some aspect of nuclear science (nuclear chemistry, nuclear physics, health physics, nuclear medicine PhD programs, and synthesis with radio-nuclides or programs such as nuclear pharmacy or pharmacology) or nuclear medicine and oncology via MD programs.Presently a member of the Chemistry Department, formerly Chairman of the Department of Chemistry, and now Dean of the College of Science at SJSU.

The American Chemical Society's Division of Nuclear Chemistry and Technology's summer schools in nuclear and radiochemistry

This successful educational program in nuclear and radiochemistry for advanced undergraduate students is described. Funding from the U.S. Department of Energy supports 24 fellowships for participants in the intensive six-week programs at San Jose State University (CA) and Brookhaven National Laboratory (NY). Students are provided transportation to and from the school site, room and board, books, lab supplies, and six units of college credit. The instructional program consists of lectures and laboratory exercises that cover the fundamentals of nuclear theory, radiochemistry, nuclear instrumentation, radiological safety, and applications in research, midicine, and industry. Guest lectures and field trips broaden the students' exposure to nuclear science. Assistance is provided in the following year to those students who wish to join a research project at a university or national laboratory, and thereafter, in their applications to graduate or professional school.

中美高中化学教科书“化学反应原理”模块微观表征插图的设计分析

微观表征插图是重要的化学教学素材,是学生对三重表征在头脑中加工内化的重要认识媒介。为了能在“化学反应原理”模块教学中更好地发挥微观表征插图的价值,通过内容分析法,对中国人教版高中化学教科书和美国高中化学教科书Chemistry: Concepts and Applications在此模块的微观表征插图设计进行了比较分析。结果显示,2种版本教科书中的微观表征插图在该模块插图总数中的占比较少,呈现最多的主题内容均为过程微观表征;缺少“化学反应的方向、限度和速率”主题的微观表征插图;2者表征的形式水平较高,但美版教材更好地融合了“宏、微、符”3类表征。最后,基于分析结果对教科书“化学反应原理”模块中微观表征插图的设计与使用提出了相关建议。     

中学化学实验教学改革及其反思

从4个方面反思中学化学实验教学改革,指出中学化学实验教学改革的基本思路是:如何更好地发挥教材中各类实验在中学化学教学的作用,从而实现中学化学教学目标;验证是化学实验的最根本功能,实验的验证性与实验在情感领域和能力、方法领域的功能并不矛盾,而是实现这些领域的功能的基础;实验教学若能从学生出发,引发学生的想法并加以验证,则能有效地发挥教材中的各类实验在化学教学中的作用,提高中学化学教学质量.     

On The Potential of Dynamic Nuclear Polarization Enhanced Diamonds in Solid‐State and Dissolution 13C NMR Spectroscopy

Dynamic nuclear polarization (DNP) is a versatile option to improve the sensitivity of NMR and MRI. This versatility has elicited interest for overcoming potential limitations of these techniques, including the achievement of solid‐state polarization enhancement at ambient conditions, and the maximization of ¹³C signal lifetimes for performing in vivo MRI scans. This study explores whether diamond's ¹³C behavior in nano‐ and micro‐particles could be used to achieve these ends. The characteristics of diamond's DNP enhancement were analyzed for different magnetic fields, grain sizes, and sample environments ranging from cryogenic to ambient temperatures, in both solution and solid‐state experiments. It was found that ¹³C NMR signals could be boosted by orders of magnitude in either low‐ or room‐temperature solid‐state DNP experiments by utilizing naturally occurring paramagnetic P₁ substitutional nitrogen defects. We attribute this behavior to the unusually long electronic/nuclear spin‐lattice relaxation times characteristic of diamond, coupled with a time‐independent cross‐effect‐like polarization transfer mechanism facilitated by a matching of the nitrogen‐related hyperfine coupling and the ¹³C Zeeman splitting. The efficiency of this solid‐state polarization process, however, is harder to exploit in dissolution DNP‐enhanced MRI contexts. The prospects for utilizing polarized diamond approaching nanoscale dimensions for both solid and solution applications are briefly discussed.

The University of Surrey&;#39;s new proton microprobe and the feasibility of PIXE-tomography for trace element analysis of biological tissues

Summary The University of Surrey Ion Beam Centre has recently installed a tandem accelerator with a new proton microprobe and the potential for sub-micron beam-spot size. The facilities for Nuclear Microscopy (NM), combining scanning transmission ion microscopy/tomography (STIM-T) and proton induced X-ray emission tomography (PIXE-T) of biological tissues are being developed. This paper will review developments in ion beam tomography of biological samples and methods in accurately producing trace-elemental maps that are meaningful. Cell composition and integrity can be seriously compromized by the preparation of the sample and by beam-induced damage, causing loss of matrix elements as well as a change in cell size. Beam-induced damage, determination of 3-dimensional X-ray attenuation and secondary fluorescence contribute to the complex nature of the reconstruction and interpretation of PIXE-tomographic data. A PIXE, STIM and Rutherford backscatter analysis of leukocytes is presented in part to test the new microprobe but also to identify areas of improvement in facilities at the university and nuclear microscopy in general, in anticipation of producing maps for more direct biological and medical research.
