The Isborn group presents their research at the ACS meeting in SF. Makenzie picks up her Wiley post-doc award, Xochitl and Joel both give posters, and Jessica wins a prize for undergraduate poster! Baby Joe makes an appearance to cheer everyone on.
Joel's paper in J. Chem. Theory Comp. examines the size of QM region necessary for computing converged aqueous absorption spectra for solutes of varying polarity. We used large QM solvation regions (up to 400 QM water molecules) to study if nonpolar solutes required less QM solvent to converge excitation energies and oscillator strengths. Surprisingly, we found that the convergence of the excitation energies computed with the CIS method correlated with solute polarity, but those for the TDDFT method did not.
Computer graphics, 3D modeling, virtual reality, and augmented reality techniques are transforming the ways heritage is protected, communicated, and understood. Students, professionals, and scholars in heritage-related fields need to develop new skills to become producers and curators of digital heritage materials.
