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.

High Temperature Corrosion of Nickel in NaVO3-V2O5 Melts

open access: yesAdvances in Materials Science and Engineering, 2017
Many alloys used at high temperature in industrial processes are Ni-based and many others contain it in appreciable quantities, so it is of interest to evaluate the performance of pure nickel in order to determine the behavior of its alloys once the ...

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Alloying effect on the ideal tensile strength of ferromagnetic and paramagnetic bcc iron [PDF]

open access: yes, 2016
Using \emph{ab initio} alloy theory formulated within the exact muffin-tin orbitals theory in combination with the coherent potential approximation, we investigate the ideal tensile strength (ITS) in the $[001]$ direction of bcc ferro-/ferrimagnetic (FFM)

Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.
