Characterization and Modeling of Industrial Phosphoric Acids' Rheological Behavior: Impact of Magnesium Monoxide on Viscosity

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the rheological behavior of industrial phosphoric acids (H3PO4) produced at the JORF–LASFAR phosphoric plant in Morocco, with P2O5 concentrations of 18%, 29%, 42%, and 54%. Rheological measurements were performed using a rotary cylinder rheometer over a shear rate range of 1–1000 s−1.

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...

Operando Monitoring Interfacial pH Gradients and Ion Kinetics in Proton‐Coupled Electron Transfer Reactions through Dual‐Loop Electrochemical Methodology

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We present a dual‐loop methodology for real‐time mapping of interfacial pH that distinguishes electric field effects from changes in proton activity. This universal tool reveals significant pH gradients and identifies ion mobility and buffer capacity as key regulators, providing crucial insights for optimizing electrocatalyst performance in energy ...

Improving Melting Efficiency through the Application of New Refractory Materials [PDF]

open access: yes, 2006
Ladle design and ladle practices have a significant effect on a foundry operation and product quality. Large steel temperature losses or instabilities in the pouring temperature are frequently compensated by tapping at higher temperatures dramatically ...

Purification of Fish Oils and Production of Protein Powders with EPA and DHA Enriched Fish Oils [PDF]

open access: yes, 2011
Eicosapentaenoic (EPA) and docosahexaenoic (DHA) in marine oils are known to provide health benefits. However, marine oils are accompanied by saturated fatty acids.

Crystal Plane Engineering of Zn Nanosheet Arrays Toward Robust Hybrid Capacitive Energy Storage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work demonstrates a dual‐phase ZnCl2 concentration strategy dynamically switching Zn2+ solvation from [Zn(H2O)6]2+ to [ZnCl(H2O)5]+. The solvation shift steers the epitaxial growth of Zn nanosheet arrays, favoring the (002) crystal plane over (101).

Interface Engineering in Solid‐State Sodium Batteries: Advances in Materials Design, Interfacial Strategies, and Multiscale Characterization

open access: yesInterdisciplinary Materials, EarlyView.
Since solid‐state sodium batteries (SSSBs) are a promising solution for advancing sodium‐based energy storage, it is necessary to systematically summarize the development process of SSSBs. It focuses on the role of interface engineering in addressing challenges such as materials design, interfacial strategies, and multiscale characterization.
