Concurrent Operando Neutron Imaging and Diffraction Analysis Revealing Spatial Lithiation Phase Evolution in an Ultra‐Thick Graphite Electrode

open access: yesAdvanced Energy Materials, EarlyView.
The lithiation phases in an ultra‐thick graphite electrode are mapped operando as a function of electrode depth through a new method concurrently combining neutron imaging and diffraction. The results reveal the coexistence of lithiation phases during cycling as well as the solid electrolyte interface (SEI) formation and capacity loss through non ...

Detecting axion stars with radio telescopes

open access: yesPhysics Letters B, 2018
When axion stars fly through an astrophysical magnetic background, the axion-to-photon conversion may generate a large electromagnetic radiation power.

The interplay of astrophysics and nuclear physics in determining the properties of neutron stars [PDF]

open access: yesarXiv
Neutron star properties depend on both nuclear physics and astrophysical processes, and thus observations of neutron stars offer constraints on both large-scale astrophysics and the behavior of cold, dense matter. In this study, we use astronomical data to jointly infer the universal equation of state of dense matter along with two distinct ...

Low‐Cost, High‐Efficiency Organic Solar Cells Based on Ecofriendly Processing Solvent

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A low‐complexity, cost‐effective donor material, PTQ10, combined with the high‐efficiency acceptor materials, BTP‐eC9 and Y6, demonstrates excellent performance with the ecofriendly solvent o‐xylene (XY) instead of the traditional chloroform (CF) for the spin‐coating method.

Mass Transfer in Eccentric Black Hole–Neutron Star Mergers

open access: yesThe Astrophysical Journal
Black hole–neutron star binaries are of interest in many ways: they are intrinsically transient, radiate gravitational waves detectable by LIGO, and may produce γ -ray bursts.
