With support from the Chemistry Research Instrumentation and Facilities: Multiuser program (CRIF:MU), the Department of Chemistry at the University of South Dakota will acquire a Cyber-enabled Transmission Electron Microscope (TEM). The microscope will be used by researchers at the University of South Dakota, and other institutions in the Great Plains region, including the members of the Northern Plains Undergraduate Research Center. The projects that acquisition of this instrumentation will enable include: (1) study of the surface sensitization of Ln-doped lanthanum trifluoride nanoparticles; (2) investigation of the potential for metal-surface enhancement of upconversion luminescence from Lanthanide-doped nanoparticles; (3) TEM studies of noble metal containing titanium dioxide aerogels; (4) the synthesis of well-defined nanocrystals for catalysis; (5) exploration of the relationship between morphology of carbonaceous materials and their catalytic activity toward alkylation, benzylic oxidation and phtooxidation; and (6) study of the properties and self-assembly of nanocomposites for surface enhanced Raman scattering in sensing applications. The microscope will be used by large numbers of undergraduate and graduate students, both in instructional settings as well as in research. Access to the instrument will be widened, via cyber-enabling and other means, to student researchers in the Great Plains region, including students at Sinte Gleska University. Transmission electron microscopes, like the one purchased under this award, allow chemists to see atomic-level details of materials that they make in their laboratories. This level of detail is especially needed when probing the chemical properties of nanoscale materials, where chemical heterogeneity changes at precisely these length scales. Without this level of detail, the progress towards new kinds of nanoscale materials will be made much more slowly. The infrastructure made available with this grant will be used in teaching and training a broad range of young scientists, including significant numbers of Native American scientists, in important, cutting-edge, experimental methods.

在化学研究仪器和设施：多用户计划 (CRIF:MU) 的支持下，南达科他大学化学系将购买一台网络驱动的透射电子显微镜 (TEM)。该显微镜将由南达科他大学和大平原地区其他机构的研究人员使用，包括北部平原本科研究中心的成员。 收购该仪器将实现的项目包括：（1）掺Ln三氟化镧纳米粒子的表面敏化研究； (2) 研究稀土掺杂纳米粒子上转换发光的金属表面增强潜力； (3)含贵金属二氧化钛气凝胶的TEM研究； （4）用于催化的明确纳米晶体的合成； （5）探索碳质材料的形貌与其烷基化、苄基氧化和光氧化催化活性之间的关系； (6) 研究用于传感应用中表面增强拉曼散射的纳米复合材料的特性和自组装。该显微镜将被大量本科生和研究生用于教学和研究。通过网络支持和其他方式，该仪器的使用范围将扩大到大平原地区的学生研究人员，包括辛特格莱斯卡大学的学生。透射电子显微镜，就像根据该奖项购买的显微镜一样，可以让化学家看到他们在实验室制造的材料的原子级细节。 在探测纳米级材料的化学性质时，尤其需要这种详细程度，因为化学异质性恰好在这些长度尺度上发生变化。 如果没有这种程度的细节，新型纳米材料的进展将会缓慢得多。这笔赠款提供的基础设施将用于教学和培训广泛的年轻科学家，包括大量的美国原住民科学家，采用重要的、前沿的实验方法。
