Effect of different surface preparations prior to painting on the corrosion behaviour and surface activity of mild steel [PDF]

open access: yes, 2010
Previous work in our laboratory showed that the type of surface preparation of the steel prior to coating had a dramatic effect on the subsequent corrosion protection afforded in immersion tests and in salt spray testing.

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...

Enhancing electrochemical performances of supercapacitors

open access: yes, 2019
The thesis is focused on the development and enhancement of the electrochemical properties of the carbon based supercapacitors and pseudocapacitors. To overcome the capacitance loss at the condition of fast charging in the carbon-based supercapacitors, a metal-oxide embedded porous carbon nanofiber with a 3-D electrode architecture is designed.

Backbone‐Controlled Ion‐Side Chain Accessibility in Conjugated Polymers for Organic Electrochemical Synaptic Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Backbone modulation in glycolated conjugated polymers governs ion accessibility to side chains, strengthes anion adsorption, and suppresses back‐diffusion. As the number of thiophene units increases, structural reorganization, retention, and synaptic plasticity are enhanced, leading to improved neuromorphic performance in electrolyte‐gated organic ...

LiF as an Alloy Component or Slurry Additive in Si-Alloy Anodes

open access: yes, 2020
Electrolyte additives are commonly used to improve electrochemical performance in Li-ion cells. The use of solids as electrolyte additives is far less common.

Spectroscopic Investigation of Polysulfide Redox Evolution in Catholyte Solutions for Potassium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Potassium–sulfur batteries are investigated using UV–vis spectroscopy to track the evolution of potassium polysulfide species at elevated temperature. The study reveals sulfur radical anions as key intermediates and shows how solvent composition and cell design influence polysulfide stability, redox behavior, and cycling performance, providing insights

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

open access: yesAdvanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.
