Electrodeposited PbO2 Thin Films with Different Surface Structure as Positive Plate in Lead Acid Batteries

International Journal of Electrochemical Science, 2018
PbO2 thin film is essential for applications in lead acid batteries system. In this work, PbO2 thin films with different surface microstructure were fabricated through electrodeposition technique by controlling the deposition current density. Though PbO2

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Molten Salt Synthesis of Disordered Spinel LiNi0.5Mn1.5O4 with Improved Electrochemical Performance for Li-ion Batteries

International Journal of Electrochemical Science, 2018
Disordered spinel LiNi0.5Mn1.5O4 (LNMO) was successfully synthesised via a molten-salt method using a mixture of LiOH⋅H2O and LiNO3 salts. The precursor was annealed at 750, 850 or 950 °C for 12 h, and the effects of calcination temperature on the ...

Electrified Damage in Motion Systems

Advanced Engineering Materials, EarlyView.
The electrified damage in motion systems is a fundamental framework presenting the degradation pathway arising from the coupling of electrical energy transport with mechanical contact and interfacial chemistry. The framework positions electrified damage as a distinct degradation regime with unique characteristic surface morphologies and failures of ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

External and Internal Cracking Caused by Heat Treatment in Laser Powder Bed Fusion‐Fabricated Inconel 738LC Components

Advanced Engineering Materials, EarlyView.
Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.

Standing as Dischargeable Referential Capacity

This paper analyzes standing as a dischargeable referential capacity rather than as an accumulated, persistent, or gradable property of agents, theories, or descriptions. It shows that standing is licensed only for specific claims under specific admissible conditions, and that it is expended—discharged—when those conditions are no longer met. Within a

High‐Temperature Phase Transformation in a V‐9Si‐6.5B Alloy: The Kinetic and Crystallographic Pathway From V5SiB2 to V8SiB4

Advanced Engineering Materials, EarlyView.
In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.
