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.

我们在日常生活中经常遇到软性材料，从软膏和乳液到油漆和墨水。了解这些软材料（通常具有流体和固体性质）以及它们如何流动或变形对于推进许多技术是必要的，包括3D打印，其中墨水或树脂的性质必须精细调整。为了使我们对软材料的科学理解取得进展，这个IRES Track I项目将加强南加州和墨西哥研究人员之间的合作。在为期三年的项目期间，每年将招募6名学生参加这项国际研究经验。来自历史上代表性不足的群体的美国学生以及主要来自本科院校和社区学院的学生将成为招生工作的目标。这些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León进行暑期研究。与墨西哥的研究导师和南加州的导师一起工作，学生将采用各种方法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油墨和树脂的设计和使用。参加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，并成为全球参与科学工作队伍的领导者。这个IRES项目将通过每年支持6名本科生参加受指导的夏季研究经验，加强美国和墨西哥研究人员之间的合作。圣地亚哥大学（University of San Diego）和加州州立大学富勒顿分校（California State University Fullerton）的pi将从历史上代表性不足的群体、以本科院校和社区学院为主的院校中招收本科生。在接受基本研究技能培训后，被选中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León度过大约8周的时间。由学生承担的研究项目将促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，量化各向异性胶体的平移和旋转扩散，以更好地了解复杂环境中的运输和微流变学，以及开发外场中胶体颗粒的计算机模拟。这些项目将导致微流变学和光学显微镜的新分析技术，并将推动3D打印油墨的发展。该项目的具体目标是：(1)在合作和国际环境中培训和指导18名（每年6名学生，为期3年）本科学生进行软物质研究；(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议的期刊上传播研究成果；(5)培养一批来自弱势群体的科学家，他们可以与来自不同背景的其他人建立有效的网络和合作，并可以利用各种各样的导师。IRES参与者将通过实验和计算方法，在从应用到基础的项目中推进科学知识。学生将学习国际团队如何使用这些不同的方法来解决紧迫的科学和工程问题。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
