MOFs for cannabis breathalyzers?
D. Ongari, Y. M. Liu, and B. Smit, Can metal–organic frameworks be used for cannabis breathalyzers? ACS Appl. Mater. Interfaces (2019) doi: 10.1021/acsami.9b13357 Abstract Δ9-tetrahydrocannabinol (THC) is the principal psychoactive component of cannabis, and there is an urgent need to build low-cost and portable devices that can detect its presence from breath. Similarly to alcohol (…)
Tail-corrections in the molecular simulations of porous materials
K. M. Jablonka, D. Ongari, and B. Smit, Applicability of J Chem Theory Comput (2019) doi: 10.1021/acs.jctc.9b00586 Abstract Molecular simulations with periodic boundary conditions require to define a certain cutoff radius rc beyond which pairwise dispersion interactions are neglected. For the simulation of homogeneous phases it is well-established to use tail-corrections, that can remedy this truncation of (…)
