项目摘要

1510826/1512113 Luo / Shah Project Overview: Water scarcity is among the most serious challenges faced by the world today. Desalination has emerged as a potential solution. This collaborative project will examine a novel water desalination technology which does not use membranes. Current water desalination technologies are either evaporation-based or membrane-based, and they are costly and energy intensive, and also contribute to global-warming CO2 emissions. The proposed research will be driven by the hypothesis that the water solubility in directional solvents can be tuned by varying their molecular structures. Monte Carlo and molecular dynamics simulations will be performed to calculate the phase-equilibria of directional solvents with salt and water as a function of temperature. The knowledge of interactions, obtained from the simulations, between the functional groups and water will form the basis of a correlation between the chemical structure and directionality of water and salt solubilities in the solvent, enabling rational design of high-performance directional solvents. According to the extracted trend, high throughput experimental screening of promising directional solvents will be performed to identify highly efficient directional solvents. Based on the directional solvents, a lab-scale continuous desalination system will be designed and demonstrated.

1510826/1512113 LUO / SHAH项目概述：缺水是当今世界面临的最严重的挑战之一。淡化已成为潜在的解决方案。这个协作项目将研究一种新的水脱盐技术，该技术不使用膜。当前的水脱盐技术是基于蒸发的或基于膜的，它们是昂贵且能源密集型的，也有助于全球温暖的二氧化碳排放。拟议的研究将由以下假设驱动，即可以通过改变其分子结构来调整方向溶剂中的水溶性。将进行蒙特卡洛和分子动力学模拟，以用盐和水作为温度的函数计算定向溶剂的相位平衡。从模拟，功能组和水之间获得的相互作用的知识将构成水结构与溶剂中水与盐溶解度之间相关性的基础，从而使高性能方向溶剂的合理设计能够理性设计。根据提取的趋势，将对有希望的方向溶剂进行高吞吐量实验筛选，以识别高效的方向溶剂。基于定向溶剂，将设计和演示实验室规模的连续脱盐系统。
