Whether the global position on CO2 emissions has reached a "tipping point" or we are embarking on new climate milestones, the overwhelming body of evidence concludes that advances in science and technology need to be embraced to bring about control of climate change. There can be no more pressing technological challenge than to reduce the global emissions from transportation. This studentship will directly address this through the understanding of the action of new Organic Friction Modifiers (OFMs), whilst also assisting in the transition from technologies relying on burning of fossil fuels (IC Engines) to the development of wind and tidal energy. To make the step change needed in the understanding (and optimisation) of OFMs, advanced techniques are required to probe the physical and chemical properties of ultra-thin films. The class of materials to be studied here is the Poly(2-oxazoline)s (POx) which have been used extensively in materials science, biochemistry, and biomedicine due to their biocompatibility and the ease of tuning parameters such as solubility, crystallinity, thermal transitions, etc. The POx of interest here have been molecularly designed to be oil soluble, while retaining strong friction-reducing properties. The objectives of the project are - To bring new techniques (in-situ atomic force microscopy) to the study of OFMs- To optimise OFM use in fully formulated oils to facilitate a reduction of 1% in the fuel consumption in the IC engine- To translate the friction and wear controlling functions of the OF molecules to the wind turbine sector through the study of micropitting in high stressed components like gears.To build tribochemistry into the modelling of friction and wear in complex contacts

无论全球二氧化碳排放状况是否达到了“临界点”，还是我们正在着手实现新的气候里程碑，压倒性的证据表明，需要利用科学和技术的进步来控制气候变化。没有比减少全球交通排放更紧迫的技术挑战了。该奖学金将通过了解新的有机摩擦改进剂（OFM）的作用直接解决这一问题，同时也有助于从依赖化石燃料燃烧（IC发动机）的技术过渡到风能和潮汐能的发展。为了在理解（和优化）OFM方面做出必要的转变，需要先进的技术来探测超薄薄膜的物理和化学性质。在这里要研究的材料类是聚（2-恶唑啉）（POx）已被广泛用于材料科学，生物化学和生物医学，由于其生物相容性和易于调整的参数，如溶解度，结晶度，热转变等POx的兴趣，在这里已被分子设计为油溶性，同时保留强大的减摩性能。该项目的目标是-将新技术（原位原子力显微镜）用于研究OFM-优化OFM在全配方油中的使用，以促进内燃机燃料消耗减少1%-通过研究齿轮等高应力部件中的微点蚀，将OF分子的摩擦和磨损控制功能转化为风力涡轮机部门。摩擦化学在复杂接触摩擦磨损建模中的应用
