I was honored to receive last week in the ACS Spring Meeting in San Diego the James J. Morgan Early Career Award. Thank you @EnvSciTech for the nice recognition.

Ben-Gurion University in the south of Israel is mourning more than 60 students, staff and faculty who were either murdered, kidnapped or missing in the Israel-Hamas war. @kellycobiella is in Be’er Sheva, Israel and speaks with the school’s president and a student.

Please check our new publication in @DesalinationJ discussing how enthalpy-entropy compensation (EEC) restricts ion-ion selectivity in salt-rejecting membranes. EEC has been documented in other fields and arguments exist weather it is real or a phantom. authors.elsevier.com/a/1fbLv…

למעבדה החדשה שלי בטכניון דרוש/ה מנהל/ת מעבדה. עדיף בעלי/ות תואר דוקטור אבל לא חובה. אשמח בעזרה בהפצה.

Happy to share our new article on ion dehydration @J_Membrane_Sci - a key phenomenon governing ion-ion selectivity in membranes. We found some strong indications of dehydration, which becomes more feasible when higher temperatures or pressures are applied. sciencedirect.com/science/ar…

Check out our new publication exploring the mechanisms that govern water-salt and ion-ion selectivity in polyamide nanofiltration membranes. Phenomena beyond simple size and charge exclusion, as well as some surprising selectivity trends are discussed. pubs.acs.org/doi/abs/10.1021…

Excited to share our new article in @ScienceAdvances: “Intrapore energy barriers govern ion transport and selectivity in desalination membranes.” Work done with Xuechen Zhou & @wang_zhangxin in @TheElimelechLab, @JaehongKim_Yale, @johnfortner & Tuan Anh Pham @Livermore_Lab

Supported by density functional theory simulation, we demonstrate that electrostatic interactions of the permeating counterion with the fixed charges on the membrane backbone significantly hinder its intrapore diffusion.

Using QCM, we break down the contributions of partitioning and intrapore diffusion to the overall energy barrier for salt transport. Overall, our results indicate that intrapore diffusion governs salt transport through subnanometer pores due to ion-pore wall interactions,
