Fabrication of Pyridinic Nitrogen‐Functionalized Carbon Cloth for High‐Performance Iron‐Chromium Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.

Vector Magnetic Fields and Current Helicities in Coronal Holes and Quiet Regions

open access: yes, 2010
In the solar photosphere, many properties of coronal holes (CHs) are not known, especially vector magnetic fields. Using observations from \emph{Hinode}, we investigate vector magnetic fields, current densities and current helicities in two CHs and ...

Separation and Enrichment of Catechol and Sugars from Bio-oil Aqueous Phase

open access: yesBioResources, 2016
Aiming at obtaining greater value from the complicated composition of the bio-oil aqueous phase, solvents of increasing polarity were employed to sequentially separate the bio-oil aqueous phase using column chromatography.

The existential crisis of bipolar II disorder

open access: yesInternational Journal of Bipolar Disorders, 2020
The issue of categorical vs. dimensional classification of bipolar disorder continues to generate controversy as it has for generations. Despite the evidence that no psychiatric disorder has discrete boundaries separating pathological and nonpathological

A Printed Zinc‐Ion Microbattery with Extended Shelf Life and Durability for Energy Autonomous Sensors

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully printed aqueous zinc‐ion microbattery (ZnIB) enabled by graphene‐decorated zinc anode and printed MnO@NC cathode using sustainable aqueous‐based ink formulations. The printed 3D electrodes ensure uniform zinc deposition, low overpotential, and long‐term stability.

Solar Sector Structure

open access: yes, 2015
The interplanetary magnetic field near has a characteristic "sector" structure that reflects its polarity relative to the solar direction. Typically we observe large-scale coherence in these directions, with two or four "away" or "towards" sectors per ...

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models

open access: yesAdvanced Functional Materials, EarlyView.
This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...

Drift and observations in cosmic-ray modulation, 2 [PDF]

open access: yes
The significant effect of drift on the radial and latitudinal dependence of cosmic rays for consecutive solar minimum periods is illustrated. Compared with the integral radial gradient observed in 1976, the calculated value seems too small.
