With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the New Mexico Institute of Mining and Technology will acquire an Electron Spin Resonance (ESR) Spectrometer. Faculty from the Departments of Physics, Chemistry, and Earth and Environmental Sciences will use this ESR instrument to carry out their research, including adsorption studies on carbon nanotubes; in situ heterogeneous catalysis investigations related to lean-burn engines; the application of zeolites in ground-water remediation; and the modification of the electronic properties of single walled carbon nanotubes (SWNT) due to chemical introduction of defects. An electron spin resonance (ESR) spectrometer is especially valuable as it provides information on short-lived free radicals. Free radicals play a major role in the initiation of tumor growth and are intermediates in many important chemical reactions. These studies should have a strong impact in the environmental arena, as they may lead to a reduction in automotive emissions and cleaner groundwater. In addition, the ESR instrument will be used in a variety of undergraduate laboratory courses in the Chemistry and Physics departments.

在主要研究仪器（MRI）项目的支持下，新墨西哥矿业与技术学院化学系将获得一台电子自旋共振（ESR）光谱仪。物理系、化学系和地球与环境科学系的教师将使用该ESR仪器进行他们的研究，包括碳纳米管的吸附研究；稀燃发动机的原位非均相催化研究沸石在地下水修复中的应用单壁碳纳米管（SWNT）的电子性能由于化学缺陷的引入而发生改变。电子自旋共振（ESR）谱仪特别有价值，因为它提供了短寿命自由基的信息。自由基在肿瘤生长过程中起着重要作用，是许多重要化学反应的中间产物。这些研究应该在环境领域产生强烈的影响，因为它们可能导致减少汽车排放和清洁地下水。此外，ESR仪器将用于化学和物理系的各种本科实验课程。
