Environmental stewardship and sustainability are major considerations for future manufacturing. Renewable, biocompatible, degradable, and nature-derived biomaterials are beginning to show great promise in a wide range of energy- and electronics-related areas. Among many material candidates, amino acids, the most basic building blocks of life, have shown intriguing properties which could make them suitable for application in semiconductor devices, energy conversion, and sustainable electronics. To realize these promises, new methods are needed to enable continuous growth of amino acid films in a manufacturing-ready system. A recent breakthrough by the team suggests that high-quality amino acid biocrystal films may be continuously produced when guided by a special interface between a polymer and a water solution. Therefore, this Future Manufacturing Seed Grant (FMSG) project seeks fundamental understanding of the interactions of the mixed materials in order to understand what controls the polymer-water interfaces in a continuous polymer extrusion system, and how the mixture in turn controls amino acid crystal formation and its properties. Knowledge obtained from this project may be transformative to the manufacturing of biocrystal thin films from amino acids and their derivatives and allow creation of structures which are otherwise unachievable by existing manufacturing techniques. Discoveries and innovations from this project will catalyze a new interface-guided manufacturing technique for biocrystal thin films, enabling a novel material paradigm for eco-friendly and biocompatible electronics and energy devices.The objective of this project is to obtain fundamental knowledge that enables transition from a static interface-guided crystallization of amino acids to a dynamic and continuous precipitation process in a manufacturing-ready system. To achieve this objective, the team will develop a new apparatus for continuously producing polymer-water bi-phase films. Experimental and computational methods will be combined to understand and predict the dynamic conditions of the water-polymer system during continuous cooling. These conditions will be used to study the continuous crystallization kinetics of amino acid crystals and explain the role of the water-polymer interface as a key controlling factor. In addition, the piezoelectric properties of amino acid crystal films, which allow conversion of mechanical energy into electricity, will be quantified as a benchmark for film quality evaluation.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.

环境管理和可持续性是未来制造业的主要考虑因素。可再生的、生物相容的、可降解的和自然衍生的生物材料开始在广泛的能源和电子相关领域显示出巨大的希望。在许多候选材料中，氨基酸，生命最基本的组成部分，已经显示出有趣的特性，可以使它们适用于半导体器件，能量转换和可持续电子产品。为了实现这些承诺，需要新的方法来使氨基酸膜在生产就绪的系统中连续生长。该团队最近的一项突破表明，在聚合物和水溶液之间的特殊界面的引导下，可以连续生产高质量的氨基酸生物晶体膜。因此，这个未来制造种子基金（FMSG）项目寻求对混合材料相互作用的基本理解，以了解是什么控制了连续聚合物挤出系统中的聚合物-水界面，以及混合物如何反过来控制氨基酸晶体的形成及其性质。从这个项目中获得的知识可能会对氨基酸及其衍生物的生物晶体薄膜的制造产生革命性的影响，并允许创造现有制造技术无法实现的结构。该项目的发现和创新将催化一种新的界面引导生物晶体薄膜制造技术，为生态友好和生物兼容的电子和能源设备提供一种新的材料范例。该项目的目标是获得基础知识，使从静态界面引导的氨基酸结晶过渡到生产就绪系统中的动态连续沉淀过程。为了实现这一目标，该团队将开发一种新的设备，用于连续生产聚合物-水双相薄膜。实验和计算方法相结合，了解和预测水-聚合物体系在连续冷却过程中的动态条件。这些条件将用于研究氨基酸晶体的连续结晶动力学，并解释水-聚合物界面作为关键控制因素的作用。此外，氨基酸晶体薄膜的压电特性（允许机械能转化为电能）将被量化为薄膜质量评价的基准。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。
