Year 1: General skills training and lab rotationsYears 2-4: Cellulose nanocrystals are rod-like nanoparticles displaying self-assembly properties that can be harnessed for high end applications. Current production methodologies rely on hydrolysis of natural cellulosic material in concentrated sulfuric acid. However, this process lacks reproducibility between batches and prediction of products property, hindering the development of commercial applications. Better comprehension of hydrolysis parameters would allow production of higher quality products. This project will investigate the potential use of a flow set-up to study the impact of reaction parameters in a consistent way, e.g. to what extent is product quality affected by the reduction of cellulose mass fraction, the effect of pre-mixing of all reagents, and process temperature. While this research highlights the challenges in developing a flow system to study cellulose nanocrystal isolation, it also opens new possibilities to both accelerate the research in batch and improve the classical protocol.

第一年：一般技能培训和实验室轮换第二年至第四年：纤维素纳米晶体是棒状纳米粒子，具有自组装特性，可用于高端应用。目前的生产方法依赖于天然纤维素材料在浓硫酸中的水解。然而，该过程缺乏批次间的再现性和产品性能的预测，阻碍了商业应用的发展。更好地理解水解参数将有助于生产更高质量的产品。该项目将研究流程设置的潜在用途，以一致的方式研究反应参数的影响，例如纤维素质量分数的降低、所有试剂预混合的效果以及工艺温度对产品质量的影响有多大。虽然这项研究强调了开发用于研究纤维素纳米晶体分离的流动系统的挑战，但它也为加速批量研究和改进经典方案提供了新的可能性。
