Thickness Dependent CO2 Adsorption of Poly(ethyleneimine) Thin Films for Direct Air Capture

January 2, 2024

Author(s)

John Hoffman, Avery Baumann, Christopher Stafford

Mesoporous silica impregnated with polyethyleneimine (PEI) has been shown to be a suitable material for the direct air capture (DAC) of CO2. Factors such as CO2 concentration, temperature, and amine loading impact overall capture capacity and amine

Trace Water Effects on Crystalline 1-Ethyl-3-methylimidazolium Acetate

May 16, 2023

Author(s)

Ashlee Aiello, John Hoffman, Anthony Kotula, Lucas Flagg, Ruipeng Li, Jeremiah Woodcock

Spontaneous room temperature crystallization of 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]) was observed upon removal of trace water. To ensure that this observation was not produced by trace water or other contaminants, sample purity was confirmed
