We encounter soft materials frequently in our everyday lives from ointments and lotions to paints and inks. Understanding these soft materials, which often possess both fluid-like and solid-like properties, and how they flow or deform is necessary for advancing many technologies, including 3D printing where the properties of the ink or resin must be finely tuned. To make progress on our scientific understanding of soft materials, this IRES Track I project will strengthen collaborations between researchers in Southern California and in Mexico. Each year over the 3-year duration of this project, 6 students will be recruited to take part in this international research experience. U.S. students from historically underrepresented groups and from predominantly undergraduate colleges and community colleges will be targeted in the recruitment effort. Those students will conduct research over the summer at either the Center for Research in Advanced Materials (Centro de Investigación en Materiales Avanzados, CIMAV) in Monterrey, Mexico or the University of Guanajuato in León, Mexico. Working with research mentors in Mexico and the mentors in Southern California, students will take various approaches to study the physics and chemistry of soft materials. Such approaches include using computer simulations to study fundamental aspects of soft materials and using 3D printers to apply our scientific understanding of soft materials to the design and use of new inks and resins. Students taking part in this research and receiving mentorship from U.S. and Mexican scientists will be prepared to cooperate with diverse teams across borders and to become leaders of a globally engaged scientific workforce. This IRES project will strengthen collaborations between researchers in the U.S. and Mexico by supporting the participation of 6 undergraduates per year in mentored summer research experiences. The PIs at the University of San Diego and California State University Fullerton will recruit undergraduate students from historically underrepresented groups and from predominantly undergraduate institutions and community colleges. After receiving training on basic research skills, selected students will spend approximately 8 weeks at either the Center for Research in Advanced Materials (Centro de Investigación en Materiales Avanzados, CIMAV) in Monterrey, Mexico or the University of Guanajuato in León, Mexico. Research projects undertaken by students will advance our understanding of soft matter, particularly in the areas of colloid science and rheology. Projects will include investigating the rheology of nanocellulose and cellulose composites for use in 3D printing applications, quantifying the translational and rotational diffusion of anisotropic colloids to better understand transport and microrheology in complex environments, and developing computer simulations of colloidal particles in external fields. These projects will lead to new analysis techniques in microrheology and optical microscopy and will advance the development of inks for 3D printing. The specific objectives of this project are to (1) train and mentor 18 (6 students per year for 3 years) undergraduate students on soft matter research in a collaborative and international environment, (2) develop and foster research collaborations among institutions in the U.S. and Mexico, (3) characterize and harness the rheological properties of complex fluids and gels for enhancing our fundamental knowledge of soft matter and for applying such materials to 3D printing applications, (4) disseminate research outcomes at scientific conferences and in peer-reviewed journals, and (5) develop a cohort of scientists from predominantly underrepresented groups who can network and collaborate effectively with others from various backgrounds and who can draw upon a diverse set of mentors. IRES participants will advance scientific knowledge in projects that range from applied to fundamental using experimental and computational approaches. Students will learn how these diverse approaches used by an international team can address pressing scientific and engineering problems.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.

我们在日常生活中会遇到软质材料，从软膏和乳液到油漆和油墨，了解这些软质材料通常同时具有类流体和类固体的特性，以及它们如何流动或变形对于推进包括 3D 在内的许多技术是必要的。为了加深我们对软材料的理解，IRES Track I 项目将在三年内每年加强南加州和墨西哥的科研人员之间的合作。这个的该项目将招募 6 名来自历史上代表性不足的群体和主要是本科院校和社区学院的学生来参加这项国际研究体验，这些学生将在夏季在该中心进行研究。墨西哥蒙特雷的先进材料研究中心（Centro de Investigación en Materiales Avanzados，CIMAV）或墨西哥莱昂的瓜纳华托大学与墨西哥的研究导师和南部的导师合作。在加利福尼亚州，学生将采用各种方法来研究软材料的物理和化学，这些方法包括使用计算机模拟来研究软材料的基本方面，以及使用 3D 打印机将我们对软材料的科学理解应用于新墨水的设计和使用。参与这项研究并接受美国和墨西哥科学家指导的学生将准备好与跨国界的不同团​​队合作，并成为全球参与的科学队伍的领导者。和墨西哥通过支持每年有 6 名本科生参加受指导的暑期研究体验。 圣地亚哥大学和加州州立大学富勒顿分校的 PI 将从历史上代表性不足的群体以及主要是本科院校和社区学院招收本科生。 ，选定的学生将在墨西哥蒙特雷的先进材料研究中心 (Centro de Investigación en Materiales Avanzados, CIMAV) 或墨西哥瓜纳华托大学度过大约 8 周的时间墨西哥莱昂，学生开展的研究项目将增进我们对软物质的理解，特别是在胶体科学和流变学领域。项目将包括研究用于 3D 打印应用的纳米纤维素和纤维素复合材料的流变学，量化平移和旋转。各向异性胶体的扩散，以更好地了解复杂环境中的传输和微流变学，以及开发外部领域中胶体颗粒的计算机模拟，这些项目将带来新的分析技术。该项目的具体目标是（1）以合作和国际方式培训和指导 18 名（每年 6 名学生，为期 3 年）本科生进行软物质研究。环境，(2) 发展和促进美国和墨西哥机构之间的研究合作，(3) 表征和利用复杂流体和凝胶的流变特性，以增强我们对软物质的基础知识，并将此类材料应用于3D 打印应用，(4) 在科学会议和同行评审期刊上传播研究成果，(5) 培养一批来自代表性不足的群体的科学家，他们可以与来自不同背景的其他人有效地建立联系和协作，并可以利用IRES 参与者将使用实验和计算方法在从应用到基础的项目中推进科学知识，学生将了解国际团队使用的这些不同方法如何解决紧迫的科学和工程问题。该奖项反映了 NSF 的法定奖项。使命通过使用基金会的智力优点和更广泛的影响审查标准进行评估，并被认为值得支持。
