Non-technical descriptionThis Research Infrastructure Improvement Track-2 Focused EPSCoR Collaboration (RII Track-2 FEC) award is a collaboration among three institutions in LA and KY -- Louisiana State University Agricultural Center, Louisiana State University A&M College, and the University of Kentucky. The research is focused on lignin chemistry - lignin is a class of complex organic polymers found in plants, particularly wood. The project will prepare synthetic lignin and deconstruct synthetic and native lignin into value-added products and functional materials. This fundamental research will provide the foundation for future technologies that would enable sustainable food, energy, and water systems. This multidisciplinary project supports sixteen faculty at early, middle, and advanced career levels, thirty graduate and 16 undergraduate students at all three participating institutions. Participants will develop curricular modules for rural high schools on sustainability science topics and implement through the involvement of vocational agriculture teachers and 4-H curricula. Project activities include public outreach to promote awareness of the connection between agriculture and science. Technical descriptionThe project seeks to synthesize model lignin compounds via biomimetic polymerization, deconstruct both the synthetic and native lignin by thermo or biochemical breakdown, and study the interfacial chemistry of lignin products using advanced experimental techniques and molecular simulations. Research tasks include: (1) Development of solid-phase lignin synthesis chemistry to build synthetic models composed of specific monolignol sequences; (2) Deconstruction of model lignin oligomers in ionic liquids with the end goal of developing a novel biocatalysis route for effective fractionation and deconstruction of natural lignin in ionic liquid medium; (3) Deconstruction of model lignin using ultrafast cooling of lignin products obtained by flash pyrolysis and low temperature matrix isolation Electron Paramagnetic Resonance techniques; and (4) Manipulation of the interfacial surface properties using thin film technology, nanoparticles, and molecular simulation to gain insight into interactions, properties, and applications of lignin derivatives at advanced materials interfaces. This interdisciplinary project will provide graduate student training, and undergraduate research experience and leverage and expand ongoing LA, KY EPSCoR initiatives in technology transfer to industry. The research and educational collaborations will lead to long-lasting impacts in both LA and KY. The project's workforce development plan includes modular curriculum development for rural high school students implemented through vocational agriculture teachers and 4-H curricula.

非技术支持这项研究基础设施改进轨道-2重点EPSCoR合作（RII轨道-2 FEC）奖是在洛杉矶和肯塔基州的三个机构之间的合作-路易斯安那州州立大学农业中心，路易斯安那州州立大学A M学院，和肯塔基州的大学。 该研究的重点是木质素化学-木质素是一类在植物，特别是木材中发现的复杂有机聚合物。 该项目将制备合成木质素，并将合成和天然木质素分解为增值产品和功能材料。 这项基础研究将为未来的技术提供基础，使可持续的粮食，能源和水系统。这个多学科项目支持16名教师在早期，中期和高级职业水平，30名研究生和16名本科生在所有三个参与机构。参与者将为农村高中制定关于可持续性科学主题的课程模块，并通过职业农业教师和4-H课程的参与实施。项目活动包括向公众宣传，以提高对农业与科学之间联系的认识。 技术支持该项目旨在通过仿生聚合合成模型木质素化合物，通过热分解或生物化学分解来解构合成和天然木质素，并使用先进的实验技术和分子模拟来研究木质素产品的界面化学。研究任务包括：（2）在离子液体中对木质素低聚物模型进行解构，最终目标是开发一种新的生物催化途径，用于在离子液体介质中有效地分离和解构天然木质素;（3）使用通过闪速热解和低温基质隔离电子顺磁共振技术获得的木质素产物的超快速冷却来解构模型木质素;以及（4）使用薄膜技术、纳米颗粒和分子模拟来操纵界面表面性质，以深入了解木质素衍生物在先进材料界面处的相互作用、性质和应用。这个跨学科的项目将提供研究生培训，本科生的研究经验，并利用和扩大正在进行的LA，KY EPSCoR计划在技术转移到行业。研究和教育合作将在洛杉矶和肯塔基州产生长期影响。该项目的劳动力发展计划包括通过职业农业教师和4-H课程为农村高中学生编制模块课程。
