This is a small equipment proposal to purchase a rheometer (Discovery Series HR-2). Obtaining this instrument will advance emerging and established research at New Mexico State University (NMSU). The availability of a high-end instrument that can give accurate measurements for fluids that are more complex than water (e.g., polymers, pastes, biological fluids, suspensions etc.) will foster a rheology-centered community among the materials engineering research strengths at NMSU, and form the core of a multidisciplinary "Viscoelastic Measurement Laboratory?. Using the instrument will also support a number of research faculty who are working between the disciplines of fluid dynamics of complex fluids, chemistry, biological sciences, and engineering. NMSU is a Hispanic-serving Institution; therefore, the number of underrepresented minorities in STEM is quite large. Upon installing the instrument for use in research, the co-PIs will implement educational activities for undergraduates and graduate students with particular engagement of underrepresented minorities. The rheometer will be used in a variety of undergraduate and graduate classes. The equipment will also be used to provide technical workshops for graduate students through the NMSU NIH RISE program, reach out to the New Mexico Farm and Ranch Heritage Museum, and to improve the interaction of faculty members with local industries in food processing, petrochemicals, refinery, plastics, and composites manufacturing - all of which impact regional economy. The departments to be directly influenced include chemical engineering, food science and technology, chemistry and biochemistry, and biology. The research projects to be studied with the rheometer include (i) the dynamics of polymer chains during asymmetric phase separation, which is controlled by viscoelasticity, (ii) rheology of cells sorted through flow cytometry, (iii) the rheology of healthy and cancerous laboratory-cultured cells, (iv) rheology of mechanosensory organs and engineered neural cultures, and (v) interfacial rheology of a new emulsifier for food products derived from cotton seed meal.

这是购买流变仪（Discovery系列HR-2）的小型设备提案。获得这一工具将推动新兴和既定的研究在新墨西哥州州立大学（NMSU）。高端仪器的可用性，可以对比水更复杂的流体（例如，聚合物、糊剂、生物流体、悬浮液等）将在NMSU的材料工程研究力量中培养以流变学为中心的社区，并形成多学科“粘弹性测量实验室”的核心。使用该仪器还将支持一些研究人员，他们正在复杂流体的流体动力学，化学，生物科学和工程等学科之间工作。NMSU是一个西班牙裔服务机构;因此，在STEM中代表性不足的少数民族数量相当大。在安装用于研究的仪器后，共同研究所将为本科生和研究生开展教育活动，特别是代表性不足的少数民族的参与。该流变仪将用于各种本科生和研究生课程。这些设备还将用于通过NMSU NIH RISE计划为研究生提供技术研讨会，接触新墨西哥州农场和牧场遗产博物馆，并改善教师与当地食品加工，石化，炼油厂，塑料和复合材料制造行业的互动-所有这些都影响区域经济。直接受影响的部门包括化学工程、食品科学与技术、化学与生物化学和生物学。使用流变仪研究的研究项目包括：（i）非对称相分离过程中聚合物链的动力学，这是由粘弹性控制的;（ii）通过流式细胞术分选的细胞的流变学;（iii）健康和癌性实验室培养细胞的流变学;（iv）机械感觉器官和工程神经培养物的流变学;和（v）一种用于棉籽粕衍生食品的新型乳化剂的界面流变学。
