Kinetics and Electrochemical Studies of Fe-substituted LiMnPO4

International Journal of Electrochemical Science, 2012
A simple sol-gel method was applied to synthesize LiMn(1-x)FexPO4 (x=0-0.5). The kinetics of LiMn(1-x)FexPO4 was studied by chemical delithiation experiment and EIS measurements. The results showed that the LiMn0.6Fe0.4PO4 has the fastest conversion rate

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.

Microstructure Changes of Amorphous Mg-Ni-Nd Alloys During Charge/Discharge Cycling and its Thermodynamic Verification

International Journal of Electrochemical Science, 2011
Amorphous Mg-based hydrogen-storage alloy (Mg70.6Ni29.4)90Nd10 is prepared by melt-spinning. The phase structures of the ribbons before and after charge/discharge cycling are characterized by high-resolution transmission electron microscopy (HRTEM), X ...

Developing the Discharge Capacity of Al Husa'chi River

Engineering and Technology Journal, 2009
Al Husa'chi River is one of the three main branches of Al Ka’hla River in Maissangovernorate. Its length is 25 km. the river directly feeds Al Huwayza Marsh by overpasspipes at its end. It is also used for irrigating the nearby agricultural areas. A study forevaluating the hydraulic performance of the river has been carried out in order to developits ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Study of Discharge Capacity of Curved Weir

AbstractThe curved weir, as an innovative weir design, offers an extended upstream edge compared to orthogonal weirs, enhancing discharge capacity across its width and ensuring river flow safety. However, for rivers of fixed width, the effects of the curved configurations, partically the central angles, on hydraulic performance, warrant further ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

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

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries
