Kurupath, Vishnu Prasad (author), Kannam, Sridhar Kumar (author), Hartkamp, R.M. (author), Sathian, Sarith P. (author)Biological nanopores such as aquaporins combine the opposing functions of high water permeation and total ion exclusion in part by the virtue of their hourglass shape. Here, we perform molecular dynamics simulations to examine water and ion conduction through hourglass shaped nanopores created from carbon nanotubes (CNTs) of chirality (6,6), ...journal article 2021

Blankert, Bastiaan (author), Vrouwenvelder, J.S. (author), Witkamp, Geert Jan (author), Ghaffour, Noreddine (author)In this study, we analyzed the heat requirement of membrane distillation (MD) to investigate the trade-off between the evaporation efficiency and driving force efficiency in a single effect MD system. We found that there exists a non-zero net driving temperature difference that maximizes efficiency. This is the minimum net driving temperature...journal article 2020

Abushaban, Almotasembellah (author)Seawater desalination is increasingly used as a means to augment freshwater supplies in regions of the world with high water stress, and reverse osmosis is increasingly the technology of choice because of the lower energy consumption compared to thermal systems. However, seawater reverse osmosis (SWRO) systems suffer from various types of...doctoral thesis 2019

Schakel, Jasper (author)Water is the most dominant substance on the planet and has always been a synonym for life. On this planet, water has always been plentiful. Therefore, the conclusion of the United Nations in 2015 was even more shocking. The United Nations estimated that in 2030 a water gap would exist of 40%. The withdrawal of fresh water would be 40% larger...master thesis 2019

Thayn Malar Motchan, Thayn (author)With the growing population and industrial development, there is more stress on natural water resources. Additionally, environmental laws make the disposal of waste streams from industries difficult. In this scenario, it is crucial to treat waste streams to recover water and possibly minerals, for reuse in the industry, reducing the dependency...master thesis 2019
