Sulfonated para‐Polybenzimidazole Membranes for Use in Vanadium Redox Flow Batteries

Advanced Energy Materials, EarlyView.
Dense sulfonated para‐PBI membranes (MS‐PBI) are tested in the VRFB. The conductivity is 10 times lower than reported for MS‐PBI gel membranes, but 10 times higher than that of meta‐PBI. The influence of membrane preparation process, thickness, and operating temperature on the VRFB performance is investigated.

Novel weak alignment techniques for nuclear magnetic resonance spectroscopy and applications to biomolecular structure determination

, 2004
Nuclear magnetic resonance spectroscopy has continuously been developing ever since its introduction as a structural method in bioscience. Recently established residual dipolar coupling techniques yield information on long-range order in weakly aligned samples as they define the orientation of vectors between nuclei in a common global reference ...

Alternative Solid‐State Synthesis Route for Highly Fluorinated Disordered Rock‐Salt Cathode Materials for High‐Energy Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

Resonance Offset Tailored Pulses for NMR Quantum Computation [PDF]

arXiv, 2000
We describe novel composite pulse sequences which act as general rotors and thus are suitable for nuclear magnetic resonance (NMR) quantum computation. The Resonance Offset Tailoring To Enhance Nutations (ROTTEN) approach permits perfect compensation of off-resonance errors at two selected frequencies placed symmetrically around the frequency of the RF

Lewis acid‐driven interlayer shifting in sub‐nm 2D covalent organic framework membranes for hydrogen purification

AIChE Journal, EarlyView.
Abstract Covalent organic framework (COF) membranes are promising for eco‐friendly separations, but precise control of pore size at the angstrom level has been challenging, limiting their application in gas separation. This study introduces a pore redistribution method to reduce pore size to the sub‐nanometer range in single‐phase COF membranes.

Predicting molecular properties of α‐synuclein using force fields for intrinsically disordered proteins

Proteins: Structure, Function, and Bioinformatics, Volume 91, Issue 1, Page 47-61, January 2023., 2023
Abstract Independent force field validation is an essential practice to keep track of developments and for performing meaningful Molecular Dynamics simulations. In this work, atomistic force fields for intrinsically disordered proteins (IDP) are tested by simulating the archetypical IDP α‐synuclein in solution for 2.5 μs.
