Professor Andrew B. Bocarsly of Princeton University is supported by the Inorganic, Bioinorganic and Organometallic Chemistry program to explore the rational synthesis of cyanogels - a class of coordination polymers based on the reactivity of cyanometalate transtion metal complexes that form as hydrogels from aqueous solution. Cyanogel processing provides a new synthetic avenue to the development of metal alloy systems and thus, these novel materials will be investigated in terms of their interesting magnetic properties and potential to act as cellular building blocks. In a separate thrust, the direct microwave processing of the cyanogel systems will be developed and the mechanism of metal formation will studied. Synthetic advantage will be taken of the faster processing times and unique absorption of 12 cm microwaves to form zerogel and aerogel states. New morphologies are expected to lead to new materials properties such as superparamagnetic and nanometric particles. This project will provide undergraduate and graduate students with an excellent introduction to interdisciplinary research. This project will also impact K-12 education in the greater Princeton, NJ area as Professor Bocarsly is actvely involved in a variety of K-12 outreach programs including the directorship of the NY/NJ Partners in Science Program, a six university consortium, that bring high school science teachers into research labs as active researchers for two consecutive summers. Professor Bocarsly also utilizes the results of his cyanogel research in his role as a science advisor to the West Windsor-Painsboro Regional School disctrict through such programs as the NSF sponsored E=mc2 inquiry-based science program, and Princeton University's Quest program. It is estimated that approximately 500 K-12 student per year are impacted by Professor Bocarsly's actvities in these programs.

普林斯顿大学的 Andrew B. Bocarsly 教授在无机、生物无机和有机金属化学项目的支持下，探索氰基凝胶的合理合成。氰基凝胶是一类基于氰基金属盐过渡金属络合物反应性的配位聚合物，可从水溶液中形成水凝胶。 氰凝胶加工为金属合金系统的开发提供了新的合成途径，因此，将研究这些新型材料的有趣的磁性和作为细胞构建块的潜力。 在单独的研究中，将开发氰凝胶系统的直接微波处理，并研究金属形成的机制。将利用更快的处理时间和对 12 cm 微波的独特吸收来形成零凝胶和气凝胶状态的综合优势。 新的形态有望带来新的材料特性，例如超顺磁性和纳米粒子。该项目将为本科生和研究生提供跨学科研究的精彩介绍。 该项目还将影响新泽西州大普林斯顿地区的 K-12 教育，因为 Bocarsly 教授积极参与各种 K-12 外展计划，包括担任纽约/新泽西科学合作伙伴计划的董事，该计划是一个由六所大学组成的联盟，连续两个暑假将高中科学教师作为活跃研究人员带入研究实验室。 Bocarsly 教授还通过 NSF 赞助的 E=mc2 基于探究的科学项目和普林斯顿大学的 Quest 项目等项目，利用他的氰凝胶研究成果，担任西温莎-潘斯伯勒地区学区的科学顾问。 据估计，每年约有 500 名 K-12 学生受到博卡斯利教授在这些项目中的活动的影响。
