Mesoporous vanadium nitride as anion storage electrode for reverse dual-ion hybrid supercapacitor

open access: yesiScience, 2022
Summary: In traditional dual-ion systems, the cathode usually is employed as anion-storage materials. Herein, we propose a new dual-ion hybrid supercapacitor with reverse anion/cation-storage mechanism, consisting of a mesoporous (MPs) VN anode as a ...

Nonlinear magneto-viscoelasticity of transversally isotropic magneto-active polymers [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014
Iron-filled magnetorheological polymers, when cured in the presence of a magnetic field, result in having a transversely isotropic structure with iron particles forming chains along the direction of applied magnetic induction. In this work, we model the magneto-viscoelastic deformation (and magnetization) process of such polymers.

Effects of Spray Drying Conditions on Morphology and Performance of Nano/Micro Structure LiFePO4/C

open access: yesCailiao gongcheng, 2018
The nano/micro LiFePO4/C composite was prepared by a wet milling-spray drying-carbothermal reduction process. The structure and morphology were characterized by X-ray diffraction (XRD) and electron scanning microscope(SEM), electrochemical properties ...

Magneto-Rossby waves in the solar tachocline and the annual variations in solar activity

open access: yes, 2019
Annual oscillations have been detected in many indices of solar activity during many cycles. Recent multi spacecraft observations of coronal bright points revealed slow retrograde toroidal phase drift (with the speed of 3 m/s of 1 yr oscillations, which ...
