Advanced Science, EarlyView.Impurity tolerance in LiFePO4 cathodes varies strongly with impurity type and content. Low Ni levels are accommodated within the lattice with minimal structural disruption, whereas higher Ni contents introduce antisite disorder. In contrast, Cr impurities segregate from the LiFePO4 framework, blocking lithium‐ion pathways and leading to inferior ...

DETERMINATION OF THE MASSES OF MINOR PLANETS J.-F. Bange, A. Bec-Borsenberger [PDF]
The observations of minor planets are of particular interest for determining a possible rotation between the Hipparcos and the dynamical reference frames. In order to evaluate it, Hipparcos data are compared to the values calculated from the equations of

Dictionary of minor planet names [PDF]
, 1997 Until recently, minor planet name citations were scattered in the astronomical literature, and the origin of many names remained obscure In 1988 the IAU Commission 20 established a study group to elucidate the meanings of asteroid names Later on the ...

Integrated photogrammetry and photoclinometry for enhanced 3D surface reconstruction of asteroids
Astronomy & AstrophysicsStereo photogrammetry (SPG) and stereo photoclinometry (SPC) are the main techniques used in the 3D surface reconstruction of asteroids. The SPG approach retrieves accurate 3D geometry with limited spatial resolution, while SPC extracts fine-scale ...

Lattice Distortion‐Driven Metal Exsolution in Perovskite Oxides
Advanced Science, EarlyView.This study elucidates the mechanism of lattice distortion‐driven exsolution through a combination of computational simulations and experimental approaches. Lattice distortion facilitates the formation of oxygen vacancies and subsequent metal segregation, thereby enhancing the exsolution behavior.

Extra Climate Benefits From Afforestation Due to Reduced Forest Fragmentation in China
Advanced Science, EarlyView.Afforestation in China reduced forest fragmentation in 2015, transforming 51.8 M ha of edge forests into interior forests. This enhanced carbon sequestration (1.4±0.2 Pg CO2e, a cooling biogeochemical effect), while reduced albedo (−0.9 Pg CO2e, a warming biophysical effect) partially offset the gain, yielding a net extra climate benefit of ...

Advanced Science, EarlyView.A phosphide‐modified multimetallic HER electrode achieves industrial‐level performance with minimal noble‐metal content. It delivers 1.7 A cm−2 at 2.0 V in 6 M KOH at 70°C and operates stably for over 200 h at 500 mA cm−2. Phosphorus tuning of the electronic structure optimizes hydrogen adsorption, offering a durable, high‐rate pathway for alkaline ...
