As a society, we are increasingly aware of the environmental impact of human activity and the dire need to develop cleaner technologies and to use our resources more efficiently. Baines is a world-renowned researcher in main group chemistry with a research focus on the synthesis and chemistry of the unsaturated derivatives of heavy Group 14 elements. The long term vision for her research program is to use her extensive knowledge and understanding of the chemistry of unsaturated Group 14 compounds to provide innovative solutions which address these important societal challenges. The proposed research can be divided into three themes. Theme 1: She proposes to synthesize ligand-stabilized silicon dications and ligand-stabilized binary germanium and tin chalcogenides and to examine the conversion of these simple complexes to nanomaterials. Theme 2: Two methods for the elaboration of ammonia to amines, reagents used in many areas of chemistry, will be examined. She will explore the insertion of alkenes into the NH bond of ammonia utilizing amido-substituted germanium or tin(II) compounds as catalysts. She will also investigate the reaction of doubly-bonded compounds of the heavier Group 14 elements with ammonia as a second method for the synthesis of functionalized amines. Theme 3: She will develop alternative methods for the synthesis of technologically important germanium and tin compounds which avoid the use of highly corrosive and toxic chlorine-based reagents. The vision is to develop industrially-relevant protocols for the processing and recycling of germanium and tin which are efficient and environmentally-friendly to ensure that these two important elements will be available for future generations. Hexacoordinate complexes of germanium and tin will be utilized as key intermediates and the synthesis and reactivity of several complexes of this type will be explored. The Baines research program will provide excellent training opportunities for students and the results will contribute new knowledge which can be used to address two important chemical challenges: how to derivatize ammonia and how to cleanly produce technologically important materials. Baines was awarded the Humboldt Research Award from the Alexander von Humboldt Foundation in Germany and the Montreal Medal from the Chemical Institute of Canada, both in 2016. She was a DAAD Scholar (Research Stay for University Academics and Scientists from the German Academic Exchange Service) at the University of Oldenburg in 2015. In the last 6 years, she has published 33 journal articles, 2 data reports and given 36 invited presentations including 4 plenaries. She has supervised 30 HQP, including several national scholarship winners. Her HQP have given 31 conference presentations across the globe. Over 90% of the students she has supervised are contributing directly to the Canadian economy as academics and professional chemists.

作为一个社会，我们越来越意识到人类活动的环境影响以及迫切需要开发清洁技术并更有效地利用我们的资源。贝恩斯（Baines）是一名世界知名的主要群体化学研究人员，研究重点是重组14个元素的不饱和衍生物的合成和化学。她的研究计划的长期愿景是利用她对不饱和集团14组化学化学的广泛知识和理解，提供创新的解决方案，以应对这些重要的社会挑战。拟议的研究可以分为三个主题。主题1：她提议合成配体稳定的硅分解，配体稳定的二元也和锡粉核化剂，并检查这些简单的复合物向纳米材料的转化。主题2：将研究在许多化学领域使用的氨氨的两种方法。她将探索利用氨基化的锗或锡（II）化合物作为催化剂的氨基烷的插入到氨的NH键中。她还将研究重14组元素与氨的双重键合成的反应，作为合成功能化胺的第二种方法。主题3：她将开发出替代技术重要葡萄牙和锡化合物的替代方法，这些方法避免使用高度腐蚀性和有毒的基于氯的试剂。愿景是开发与工业相关的协议，用于处理和回收锗和锡的加工和回收，这些方案有效且环境友好，以确保将这两个重要要素用于子孙后代。将探索也将探索锗和锡的六角形复合物作为关键中间体，并将探索这种类型的几种复合物的合成和反应性。 贝恩斯研究计划将为学生提供极好的培训机会，结果将为新知识提供新的知识，这些知识可用于应对两个重要的化学挑战：如何衍生氨以及如何清洁生产具有技术重要的材料。 贝恩斯（Baines）于2016年获得了德国亚历山大·冯·洪堡基金会（Alexander von Humboldt Foundation）的洪堡研究奖，并获得了加拿大化学研究所的蒙特利尔奖章。她曾是一名DAAD学者（在2015年的Oldenburg大学学术界的研究住宿和德国学术交流服务的研究住宿），2015年在过去6年中。在过去的6年中，她的PLER LELSIISE撰写了33份杂志，并撰写了33个杂志。她已经监督了30个HQP，其中包括几位国家奖学金获奖者。她的HQP在全球举行了31次会议演讲。她监督的学生中有90％直接作为学者和专业化学家直接为加拿大经济做出了贡献。
