Single Domain Magnetic Nanoparticles as Magneto-Mechanical Actuators for Remote Drug Release from Polyelectrolyte Microcapsules

open access: yesMedical Sciences Forum, 2022
The modification of capsule shells with synthesized magnetic iron oxide nanoparticles aims not only to control the localization of capsules, but also to tune their permeability. The application of a super low frequency non-heating magnetic field (100 Hz)

Regio-selective substitution at the 1,3- and 6,8-positions of pyrene for the construction of small dipolar molecules [PDF]

open access: yes, 2015
© 2015 American Chemical Society. This article presents a novel asymmetrical functionalization strategy for the construction of dipolar molecules via efficient regioselective functionalization along the Z-axis of pyrene at both the 1,3- and 6,8-positions.

Analyzing Discrepancies in Chemical-Shift Predictions of Solid Pyridinium Fumarates

open access: yesMolecules, 2021
Highly accurate chemical-shift predictions in molecular solids are behind the success and rapid development of NMR crystallography. However, unusually large errors of predicted hydrogen and carbon chemical shifts are sometimes reported.

Generalized crystallography [PDF]

open access: yes, 2002
X-ray crystal structure analysis can now be seen as a special kind of microscopy which is being extended to the recognition and examination of many kinds of ordered structure more general than crystals and which leads to their synthesis or construction ...

Formation of a highly dense tetra-rhenium cluster in a protein crystal and its implications in medical imaging

open access: yesIUCrJ, 2019
The fact that a protein crystal can serve as a chemical reaction vessel is intrinsically fascinating. That it can produce an electron-dense tetranuclear rhenium cluster compound from a rhenium tricarbonyl tribromo starting compound adds to the ...

Predicting Accurate Lead Structures for Screening Molecular Libraries: A Quantum Crystallographic Approach

open access: yesMolecules, 2021
Optimization of lead structures is crucial for drug discovery. However, the accuracy of such a prediction using the traditional molecular docking approach remains a major concern.
