The impact of carbon-based deposits on climate change and human health is the driver for legislation, fuel technology change and engineering improvements. The carbon species produced by the internal combustion engine have various impacts on emissions and despite many years of research are still not fully understood. Recent work at Nottingham1-3 has shown a paradigm shift in the understanding of these deposits and has had subsequent impact in their reduction.The work has informed industry produce to develop mitigation chemistries to be produced and thus reduce emissions. The project is a unique opportunity to use very sophisticated surface science techniques such as Orbitrap 3D secondary ion mass spectrometry (SIMS) and X-ray photoelectron spectroscopy (XPS). The study will involve carbon material from across the powertrain vista, road, rail, off road, marine, and standing. The material will be associated with injector deposits, filter deposits to enable emission reduction and soot, especially those associated with respiratory inflammation cardiovascular health problems and premature mortality. The information regarding the structure of these species will be used to invent mitigation strategies for the benefit of all. Though the work is focussed on carbon this is a unique opportunity to learn to use and interpret data from "state of the art" instrumentation yielding important portability skill sets.References1.

碳基沉积物对气候变化和人类健康的影响是立法、燃料技术变革和工程改进的驱动力。内燃机产生的碳物质对排放有各种影响，尽管多年的研究仍然没有完全了解。最近在诺丁汉1 -3的工作表明，对这些沉积物的理解发生了范式转变，并对减少沉积物产生了后续影响。这项工作为工业生产提供了信息，以开发将要生产的缓解化学品，从而减少排放。该项目是一个使用非常复杂的表面科学技术的独特机会，如Orbitrap 3D二次离子质谱（西姆斯）和X射线光电子能谱（XPS）。这项研究将涉及碳材料从整个动力系统远景，公路，铁路，越野，海洋和站立。该材料将与喷射器沉积物、过滤器沉积物相关联，以实现减排和烟尘，特别是与呼吸道炎症心血管健康问题和过早死亡相关的那些。关于这些物种结构的信息将用于发明造福所有人的缓解战略。虽然这项工作的重点是碳，这是一个独特的机会，学习使用和解释数据的“国家的最先进的”仪器产生重要的便携性技能集。“Spatially Resolved Molecular Compositions of Insoluble Multilayer Deposits Responsible for Increased Pollution from Internal Combustion Engines”Max K Edney，Joseph S Lamb，Matteo Spanu，艾米丽F Smith，Elisabeth Steer，Edward威尔莫特，Jacqueline Reid，Jim Barker，Morgan R亚历山大，Colin E Snape，大卫J Scur.，ACS应用材料与界面12（45），51026-51035，2020.2。“使用3D OrbiSIMS和XPS深度剖析的内部柴油喷射器存款化学形态和定量”，Joseph S Lamb、Jim Barker、Edward威尔莫特、大卫J Scurr、Colin E Snape、艾米丽F Smith、Morgan R亚历山大、Jacqueline Reid。SAE International Journal of Advances and Current Practices in Mobility，2020，349 3643。“Molecular formula prediction for chemical filtering of 3D OrbiSIMS Datasets”Max K Edney，安娜M Kotowska，Matteo Spanu，Gustavo F特林达德，Edward威尔莫特，Jacqueline Reid，Jim Barker，Jonathan W Aylott，亚历山大G Shard，Morgan R亚历山大，Colin E Snape，大卫J Scurr.分析化学，94，11，4703-4711
