Using X-ray derived charge densities to detect electron delocalization effects and non-covalent interactions

open access: yes, 2012
Being based on a quantum observable and measurable quantity, the Electron Density (ED) based descriptors retain the advantage of enabling a direct comparison of theoretical predictions with experimental results.

Ab initio computations of the fourth-order charge density moments of 48Ca and 208Pb

open access: yesPhysics Letters B
Neutron skins of neutron-rich nuclei connect nuclei with the matter in neutron stars. High-precision measurements of nuclear charge densities to extract higher-order moments are proposed to be sensitive to neutron radii and skin thicknesses.

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Electrostatic Field Formed by Charge Separation in Magnetic Reconnection with a Guide Field

open access: yesThe Astrophysical Journal
The formation of charge separation in antiparallel magnetic reconnection has previously been investigated in S. Hu et al., and the results show that the charge separation arises from the combined effects of the parallel electron flux and the changes in ...

Predicting the electron density of charged systems using machine learning

open access: yesThe Journal of Physical Chemistry A
The prediction of the electron density in molecules and crystals is a key pillar in the first principles computation of their properties. Using machine learning to predict the electron density by using the atomic structure alone can save the computational cost of performing first principles computations.

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.
