This award is supported by the Major Research Instrumentation and the Chemistry Instrumentation Programs. Professor Madalyn Radlauer from San Jose State University and colleagues Melanie McNeil, Chester Simocko and Eric Tillman are acquiring a gel permeation chromatograph (GPC) equipped with refractive index, ultrviolet and multiangle light scattering detectors. In general, gel permeation chromatography is used to separate compounds based on molecular weight, size, and shape. The technique is commonly employed for the analysis or purification of polymers. The award support collaborations in polymer science between San Jose State University and Santa Clara University which promote research experiences for their large and diverse undergraduate student bodies. Summer research students are recruited from nearby community colleges thus expanding research training. The instrument gives students experience using vital instrumentation that they carry with them into their careers.The award provides gel permeation chromatograph instrumentation useful for examining polymers used as catalyst scaffolds as well as for studies of precision polymers used for ion transport and energy storage. The GPC is employed in evaluating the effect of additives on the morphology and performance of polysulfone water purification membranes and for studying post-polymerization reactions leading to topological architectures such as cyclic polymers, star polymers, and branched polymers. The instrument is helpful for investigations of redox-active polymers used in organic batteries and other charge storage devices. Other uses of the GPC are for determining structure-property relationships of recycled polymers and composites. Finally, the instrument is used for studies of the effects of irradiation-based sterilization techniques on the properties of polymers used in implantable devices.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项得到了主要研究仪器和化学仪器项目的​​支持。圣何塞州立大学的 Madalyn Radlauer 教授及其同事 Melanie McNeil、Chester Simocko 和 Eric Tillman 正在购买一台配备折射率、紫外线和多角度光散射检测器的凝胶渗透色谱仪 (GPC)。通常，凝胶渗透色谱用于根据分子量、大小和形状分离化合物。 该技术通常用于聚合物的分析或纯化。该奖项支持圣何塞州立大学和圣克拉拉大学之间在聚合物科学领域的合作，促进其庞大而多样化的本科生群体的研究经验。从附近的社区学院招募暑期研究生，从而扩大研究培训。该仪器为学生提供了使用他们在职业生涯中随身携带的重要仪器的经验。该奖项提供凝胶渗透色谱仪器，可用于检查用作催化剂支架的聚合物以及用于离子传输和能量存储的精密聚合物的研究。 GPC 用于评估添加剂对聚砜水净化膜的形态和性能的影响，并用于研究导致环状聚合物、星形聚合物和支化聚合物等拓扑结构的后聚合反应。该仪器有助于研究有机电池和其他电荷存储装置中使用的氧化还原活性聚合物。 GPC 的其他用途是确定回收聚合物和复合材料的结构-性能关系。最后，该仪器用于研究基于辐射的灭菌技术对植入式设备中使用的聚合物性能的影响。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响进行评估，被认为值得支持审查标准。
