With support from the Chemistry Research Instrumentation and Facilities: Multiuser program (CRIF:MU), the Department of Chemistry at the University of California will acquire a Cyber-enabled X-Ray Photoelectron Spectrometer (XPS) System. The spectrometer will be used by researchers at UCLA, neighboring comprehensive universities and colleagues in South America to study a number of problems in the chemical sciences. These include: (1) the electronic properties in periodic surfactant-templated semiconductors; (2) potential electrode and capacitive energy storage materials; (3) the synthesis of new types of conducting polymer nanofiber-metal nanocomposites; (4) new methods to pattern and array proteins in the nano- to micro-scale range; (5) studies of laser-assisted chemical vapor deposition of metals and binary compounds; and (6) potential methods for generating nanometer resolution patterns. The spectrometer 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 students at Cal Poly Pomona and California State University Los Angeles. In addition, a research group at CNEA, Buenos Aires will use the instrumentation, remotely, in their studies of functionalized mesoporous thin films. The x-ray photoelectron spectrometers, like the one purchased under this award, allow chemists to probe the atom-by-atom structure of materials with extraordinarily high resolution and with depth profiling up to tens of nanometers. This level of detail is especially needed when probing the chemical properties of nanoscale materials, where the 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 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，加州大学化学系将获得一个网络支持的X射线光电子能谱仪（XPS）系统。该光谱仪将由加州大学洛杉矶分校的研究人员，邻近的综合性大学和南美的同事使用，以研究化学科学中的一些问题。 其中包括：（1）周期性表面模板半导体的电子性质;（2）电势电极和电容储能材料;（3）新型导电聚合物纳米纤维-金属纳米复合材料的合成;（4）在纳米到微米尺度范围内图案化和排列蛋白质的新方法;（5）金属和二元化合物的激光辅助化学气相沉积的研究;和（6）产生纳米分辨率图案的潜在方法。光谱仪将被大量的本科生和研究生使用，无论是在教学环境中，以及在研究中。通过网络和其他手段，加州理工大学波莫纳分校和加州州立大学洛杉矶的学生将能够更广泛地使用该仪器。 此外，布宜诺斯艾利斯CNEA的一个研究小组将远程使用该仪器进行功能化介孔薄膜的研究。X射线光电子能谱仪，就像在这个奖项下购买的，允许化学家探测材料的原子结构，具有非常高的分辨率和高达几十纳米的深度分布。 当探测纳米材料的化学性质时，这种细节水平是特别需要的，其中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的重要，尖端，实验方法。
