Organic electrode materials are considered the next generation of battery electrode materials due to their environmental friendliness, low toxicity and competitive specific capacities. Herein, we report on a systematic study of processing of the redox polymer poly(3‐vinyl‐N‐methylphenoxazine) (PVMPO) using water processable binders, achieving ...

Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers
ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.

The Vertical Metallicity Gradient of the Galactic Disk for Mono-age Stellar Populations in LAMOST
The vertical metallicity gradient of the Galactic disk offers valuable insights into the disk’s formation and chemical evolution over time. We utilized the Large Sky Area Multi-Object Fibre Spectroscopic Telescope low-resolution spectral young stellar ...

A review of multiscale numerical modeling of rock mechanics and rock engineering
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Graphical overview of derivation and testing of multiparametric trajectories of cardiac function. This study identified six trajectories of LV systolic and diastolic function from mid‐ to late‐life. Predicted trajectory from single echocardiogram identified four trajectories at differential risk for HFpEF and HFrEF.

The Theory of Spiral Structure of Galaxies [PDF]
A Landau-type instability mechanism for generating spiral waves is suggested.Two populations of stars, Populations I and II, are considered, the second one with mean rotational velocity zero. Then a dispersion relation is derived which is reduced to the Lin-Shu dispersion relation in the case of vanishing Population II. The amplification of the wave is
