Investigation of the Degree of Functionalization and Colloidal Stability of Shell‐by‐Shell Functionalized TiO2 Nanoparticles as a Function of Different Phosphonic Acid Chain Lengths

open access: yesChemistry – A European Journal, EarlyView.
The Shell‐by‐Shell structures of TiO2 nanoparticles, phosphonic acids (PAs) and sodium dodecylbenzenesulfonate (SDBS) in their solid and colloidal state were studied by thermogravimetric analysis and analytical ultracentrifugation. This combination showed that agglomerates were formed whose size depended on the PA chain length. This allowed conclusions

Fine‐Tuning the Motion of Tetrafluoro‐1,4‐Benzoquinone Within Charge‐Transfer Cocrystals Through Variation of the Donor: An Entropic and Enthalpic Point of View

open access: yesChemistry – A European Journal, EarlyView.
Five CT cocrystals using TFBQ and fused, polycyclic donors derived from fluorene are synthesized. The π‐stacking in all cocrystals provides a platform for the displaying of in‐plane molecular motions of TFBQ, which is by supramolecular interactions.

Quantum Chemistry Based Simulation of Enantioseparation on Cyclodextrin‐ and Polysaccharide‐Based Chiral Stationary Phases

open access: yesChemistry – A European Journal, EarlyView.
We employed a systematic quantum chemistry‐based computational approach for simulating chiral HPLC, incorporating high‐level DFT methods. For the popular polysaccharide‐based CSPs, 90%$\%$ of determined elution orders were computed correctly. Abstract We assess the capability of modern quantum chemical methods to simulate enantioseparation on chiral ...

The NLS3 Motif in TPX2 Regulates Spindle Architecture in Xenopus Egg Extracts

open access: yesCytoskeleton, EarlyView.
ABSTRACT A bipolar spindle composed of microtubules and many associated proteins functions to segregate chromosomes during cell division in all eukaryotes, yet both spindle size and architecture vary dramatically across different species and cell types.
