Varying the Electronics on Isothiourea Catalysts: Basicity, Rate, and Selectivity

open access: yesEuropean Journal of Organic Chemistry, Volume 27, Issue 44, November 25, 2024.
Substituted benzoisothiourea catalysts were studied to understand how changing catalyst electronics affects rate and selectivity in a model reaction. This information ultimately indicates how intermolecular interactions are affected between catalyst and substrates.

Application of Inverse Liquid Chromatography for Surface Characterization of Biomaterials [PDF]

open access: yes, 2016
In the present study, a novel approach for surface characterization of ceramic biomaterials is proposed. Two ceramic biomaterials—hydroxyapatite and β-tricalcium phosphate—were examined by means of inverse liquid chromatography.

Best of both worlds: An expansion of the state of the art pKa model with data from three industrial partners

open access: yesMolecular Informatics, Volume 43, Issue 10, October 2024.
This work is a follow‐up to our previous “Best of Both Worlds” 2015 publication in Journal of Chemical Information and Modeling. It was met with a great interest from the Journal readers enjoying 4771 views and 79 citations to date. Back then, we have described S+pKa ‐ a novel predictive model of ionization constants built from a combined large data ...

Tweezer Dyads for H‐Bond Assisted Cooperativity in Tandem Uncaging Systems

open access: yesChemistry – A European Journal, Volume 30, Issue 53, September 19, 2024.
Tweezer dyads synthesized by click chemistry harness large two‐photon absorption in the NIR region from quadrupolar antenna and enhancement of the uncaging efficiency via electron transfer sensitization leading to very high two‐photon sensitivity. Abstract “Tandem” uncaging systems, in which a photolabile protecting group (PPG) is sensitized by an ...

Cosmic Strings Stabilized by Fermion Fluctuations

open access: yes, 2011
We provide a thorough exposition of recent results on the quantum stabilization of cosmic strings. Stabilization occurs through the coupling to a heavy fermion doublet in a reduced version of the standard model. The study combines the vacuum polarization

Positioning dynamic polymeric materials within the modern polymer economy: From application to recycling and circularity

open access: yesJournal of Polymer Science, Volume 62, Issue 15, Page 3562-3583, 1 August 2024.
Abstract Innovations in dynamic polymeric materials offer prospects to improve the circularity and lower the environmental impact of the modern polymer economy. These materials are also beginning to blur the distinction between re‐use and recycling methods since the bulk material properties of the material may be rationally changed after applying a ...

The Poisson-Boltzmann model for implicit solvation of electrolyte solutions: Quantum chemical implementation and assessment via Sechenov coefficients. [PDF]

open access: yes, 2019
We present the theory and implementation of a Poisson-Boltzmann implicit solvation model for electrolyte solutions. This model can be combined with arbitrary electronic structure methods that provide an accurate charge density of the solute.
