Intellectual MeritThis renewal project provides an opportunity for deaf and hard of hearing studentsto participate in classroom and laboratory research work in the field of polymers. Asmall group of college-age students will perform an internship at Tufts University for sixweeks during the summer. The classroom and laboratory components address thematerials chemistry and physics of polymers and polymer-based nanocomposites,crystallization and melting of polymers, the interaction of X-rays and light withpolymers, mechanical properties of polymers, and the connection between thermalprocessing, structure, and ultimate properties of polymers. To prepare the students forparticipation in the scientific community, a strong component of pre-professional trainingis incorporated, including discussion of ethical issues in the performance of research andin scholarship. The goals of the laboratory research component are to: expose thestudents to the laboratory environment; introduce them to the concepts of formulating andtesting hypotheses; assist students to conduct systematic studies while controllingvariables; illustrate the use of modern analytical equipment; and demonstrate theconnection between processing variables, structure, and properties.The students will make and characterize polymer-based nanocomposite filmscomprising a semicrystalline polymer matrix and an additive, which will be eitherorganically modified silicates (clay) or glass nanospheres. This research will contributeto a fundamental understanding of the effects of nanoparticles on the structure andproperties of semicrystalline polymers. In this renewal, we will emphasize mechanicalproperty measurements, using newly available instrumentation. Broader ImpactThe program is aimed at a disadvantaged minority population, of deaf and hard ofhearing college age students. The unique attributes of this program are its emphasis on:1. Teamwork; 2. Performance of a start-to-finish research project; 3. Materials sciencebasedapproach; and 4. Diversity. Students of all disability levels are candidates for thisprogram, including those students who neither hear nor voice. The broader impact willbe to bring deaf and hard of hearing students into the larger scientific community asprofessionals, by providing positive scientific experiences at a formative time in theireducational lives. The long-range goal of the proposed program is to increaseparticipation of deaf and hard of hearing students in science and engineering, and provideenrichment and mentoring for these students.

智力优点这个更新项目为聋人和听力困难的学生提供了一个机会，让他们参与聚合物领域的课堂和实验室研究工作。一小群大学生将在夏季在塔夫茨大学实习六周。教室和实验室的组成部分解决材料的化学和聚合物和聚合物基纳米复合材料的物理，聚合物的结晶和熔融，X射线和光与聚合物的相互作用，聚合物的机械性能，以及热加工，结构和聚合物的最终性能之间的联系。为了让学生做好参与科学界的准备，我们纳入了专业前培训的一个重要组成部分，包括讨论研究和奖学金中的道德问题。实验室研究部分的目标是：让学生接触实验室环境;向他们介绍制定和检验假设的概念;帮助学生在分析变量时进行系统研究;说明现代分析设备的使用;并展示了加工变量、结构和性能。学生将制作和表征聚合物基纳米复合薄膜，包括半结晶聚合物基体和添加剂，其可以是有机改性的硅酸盐（粘土）或玻璃纳米球。本研究将有助于从根本上了解纳米粒子对半结晶聚合物结构和性能的影响。在这次更新中，我们将强调机械性能测量，使用新的可用仪器。 更广泛的影响该方案的目标是弱势少数群体，聋人和重听大学年龄的学生。该计划的独特属性是它的重点：1。团队合作; 2.一个从开始到结束的研究项目的性能; 3。材料科学为基础的方法;和4.多样性所有残疾程度的学生都是这个项目的候选人，包括那些既听不见也不能说话的学生。更广泛的影响将是通过在他们教育生活的形成时期提供积极的科学经验，将聋人和重听学生作为专业人员带入更大的科学界。该计划的长期目标是增加聋人和重听学生对科学和工程的参与，并为这些学生提供丰富和指导。
