Binding of cadmium to soil humic acid as a function of carboxyl group content

Macedonian Journal of Chemistry and Chemical Engineering, 2010
The binding of Cd(II) to soil humic acid (HA) at pH 6.5 and in 0.1 mol/L KNO3 ionic medium, was studied by potentiometric titration with a cadmium ion selective electrode.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Rate constants for the reaction of NO and HO2 with peroxy radicals formed from the reaction of OH, Cl or NO3 with alkenes, dienes and α,β-unsaturated carbonyls [PDF]

, 2003
Rate constants for the gas-phase reaction of NO and HO2 radicals with 33 peroxy radicals are presented. The peroxy radicals are derived from the addition of either OH, Cl, or NO3 radicals, followed by addition of O2, to a series of alkenes ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Visible Opacities of S-type Stars: The d 3Φ–a 3Δ Band System of ZrO

The Astrophysical Journal
ZrO is a well-studied metal monoxide because of its astrophysical importance in characterizing S stars. The bands of the d ^3 Φ–a ^3 Δ system ( γ system) with ${v}^{{\prime} }\leqslant 4$ and v ″ ≤ 5 are rotationally analyzed using the PGOPHER program to
