Jingyi Chen Successfully Defends Doctoral Dissertation

January 14, 2021

Jingyi Chen has successfully defended her doctoral dissertation entitled “Molecular Simulation Studies of Aqueous Interfacial Fluids." Jingyi joined the chemistry graduate program in 2015 after receiving her undergraduate degree from Nanjing University. She will stay at UMN for a short while, then start a postdoctoral position at Pacific Northwest National Laboratory. We wish Jingyi all the best in her future endeavors!

Professor Siepmann Named Editor-in-Chief of Journal of Chemical & Engineering Data

September 15, 2020

The Publications Division of the American Chemical Society (ACS) has named Prof. Siepmann editor-in-chief of the Journal of Chemical & Engineering Data.

The Journal of Chemical & Engineering Data was first introduced in 1959 and focuses on data on the phase behavior and the physical, thermodynamic and transport properties of well-defined materials, including complex mixtures of known compositions.

TraPPE website is back!

April 9, 2020

The widely used TraPPE website has been moved to a new address, and new features have been added. Our sincere apologies for the prolonged absence, but a malicious attack led to the shutdown of the previous TraPPE server. The new TraPPE website now also includes the TraPPE-UA2 models and, for selected molecules, parameter files in Foyer XML format and molecular structures and energies.

Groundbreaking process for creating ultra-selective separation membranes published in Nature

March 15, 2017

A team of researchers, led by the University of Minnesota, has developed a groundbreaking one-step, crystal growth process for making ultra-thin zeolite nanosheets and demonstrated their use as ultra-selective membranes for chemical separations. Peng Bai, Evgenii Fetisov,  Raghu Thyagarajan, and Rob DeJaco performed electronic structure calculations and molecular dynamics and Monte Carlo simulations to aid the structure determination and probe the transport and adsorption selectivities.
