Novel Surfactants and Cleaning Technologies

几个世纪以来，清洁是家庭和工业过程的一项基本任务，这需要大量的资源，如水和能源。为了给我们的社会提供一个可持续的未来，迫切需要在减少清洁所需的资源方面进行创新。这个项目的目的是开发用于去除复杂食品污垢的创新表面活性剂。在2009年开发的清洁地图(Fryer和Asteriadou，Trends Food Science.Technol)的基础上，UOB团队近年来建立了关于食品污染和清洁的新见解(O.Herrera-Márquez等人)。J.更干净的刺激物。第261,2020年，121254；阿维拉-西耶拉等人。ACS应用程序马特。接口。我们将量化食品清洗过程中涉及的物理变化，如复杂食品的表面能、固体底物的物理化学特性、作为所用表面活性剂的函数的液-液界面能、食品污染剂的杨氏模数、小分子在基质中的扩散动力学、作为pH和离子强度函数的表面粘附性、食品污染剂的粘附性。将使用的技术包括定制的微操作、纳米压痕、接触角测角仪、界面张力计、UV-Vis、太赫兹成像、SWIR高光谱成像、共聚焦显微镜和微流控设备。预计该项目将识别和/或优化一系列用于可持续清洁的新型表面活性剂，从而将所需资源保持在最低水平。

For centuries, cleaning is an essential task for both household and industrial processes, whichrequires considerable amount of resources such as water and energy. To deliver a sustainablefuture for our society, innovation is urgently required in reducing the resource required forcleaning.The aim of this project is to develop innovative surfactants for removal of complex food soils.Building upon the Cleaning Map developed in 2009 (Fryer and Asteriadou, Trends Food Sci.Technol.), new insights concerning food fouling and cleaning have been established by the UoBteam in recent years (O. Herrera-Márquez et al. J. Cleaner Prod. 261, 2020, 121254; Avila-Sierraet al. ACS Appl. Mater. Interfaces. 13, 2021, 35506), using advanced analytical methods acrossmultiple length scales.We will quantify the physical transformations involved in a food cleaning process such assurface energy of complex food, physico-chemical characteristics of the solid substrate, liquid-liquid interfacial energy as a function of surfactants used, Young's modulus of food foulant,diffusion kinetics of small molecules in matrix, surface adhesion as a function of pH and ionicstrength, cohesiveness of food foulant. Techniques to be used include a custom-buildmicromanipulation, Nanoindentation, contact angle goniometer, interfacial tensiometer, UV-vis,terahertz imaging, SWIR hyperspectral imaging, confocal microscopy, and microfluidic devices.It is envisaged that the project will identify and/or optimise a series of novel surfactants forsustainable cleaning whereby resources required could be kept at minimal level.
