The Manifestation of the Electrochemical Potential Gradient in the Kinetic Landscapes of Interfacial Electrochemistry

open access: yesAngewandte Chemie International Edition, EarlyView.
The overpotential constitutes an electrochemical potential difference at the solid–liquid interface, which can manifest itself in different ways. In general, it can not only drive the reaction along the reaction coordinate, but also modulate chemical potentials in the extended environment that shape activation barriers, without necessarily being a ...

Impact of Galactolipids and Phosphatidylcholine on the Stability of Microalgal Oil‐In‐Water Emulsions

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Microalgal oil is a sustainable source of omega‐3 polyunsaturated fatty acids. However, it is very sensitive to lipid oxidation, especially in emulsions. While the presence of phospholipids and galactolipids in microalgal oil can influence its oxidation, their impact in oil‐in‐water emulsion is not yet fully understood. This study investigates

A new method of accurate broken rotor bar diagnosis based on modulation signal bispectrum analysis of motor current signals [PDF]

open access: yes, 2014
Motor current signature analysis (MCSA) has been an effective way of monitoring electrical machines for many years. However, inadequate accuracy in diagnosing incipient broken rotor bars (BRB) has motivated many studies into improving this method.

Zn/Al‐NO3 Layered Double Hydroxide as Alternative Activator for Nitrile Rubber Vulcanization: Effect of the Accelerator‐to‐Sulfur Ratio on Curing Kinetics and Network Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Zn/Al‐NO3 layered double hydroxide offers a low‐zinc alternative for sulfur vulcanization of nitrile rubber, reducing nominal zinc loading by an estimated 71%. Its potential as a vulcanization activator depends on the curing system: conventional curing preserves tensile strength despite slower kinetics, whereas efficient curing maintains comparable ...

Crystallization‐Induced Emission Enhancements of Hybrid Butenolide‐Diphenylethenes

open access: yesChemistry – A European Journal, EarlyView.
Hybrid butenolide‐diphenylethene fluorophores show crystallization‐induced emission enhancement (CIEE), with substituents tuning solid‐state quantum yields up to 50%. One derivative, BuCM, displays dual‐state emissions (DSE), making this compact scaffold a promising platform for CIEE/DSE‐active fluorophores.
