Understanding the dissolution of boehmite in highly alkaline solutions is important to processing complex nuclear waste stored at Hanford (WA) and Savannah River (SC) sites United States. Here, we report adsorption model carboxylates on nanoplates their effects 3 M NaOH 80 °C. Although expectedly lower than circumneutral pH, oxalate occurred pH 13, with decreasing linearly NaOH. Classical molecular dynamics simulations suggest that dianions onto surface under high can occur through either...
The synthesis of a series antioxidant polymers with varied capability to scavenge radicals and alter the wettability surfaces is reported.
We explore synthetic polymeric antioxidants as powerful inhibitors of corrosion metals. Antioxidant copolymers were designed to have polyphenol, gallol, or catechol moieties along with hydrophobic groups brought by hexyl methacrylamide units. The polymers deposited on aluminum alloy 2024-T3 submicrometer thick films individual 10 wt % additives epoxy-based ∼100 μm coatings. Thin antioxidant polymer provided significant protection AA2024. Unlike poly(hexyl methacrylamide), which lacked...
Gibbsite, bayerite, and boehmite are important aluminum (oxy)hydroxide minerals in nature have been widely deployed various industrial applications. They also major components caustic nuclear wastes stored at U.S. locations. Knowledge of their crystallization phase transformation processes contributes to understanding occurrence could help optimize waste treatment processes. While it has reported that partial conversion bayerite gibbsite occurs basic solutions elevated temperatures,...
We report on mechanically strong, water-insoluble hydrogen-bonded nanofiber mats composed of a hydrophilic polymer and natural polyphenol that exhibit prolonged antioxidant activity. The high performance fibrous resulted from the formation network hydrogen bonds between low-molecular-weight (tannic acid, TA) water-soluble (polyvinylpyrrolidone, PVP) could be precisely controlled by TA-to-PVP ratio. Dramatic enhancement (5- to 10-fold) in tensile strength, toughness, Young's moduli PVP/TA...
Here, we examine how radiation impacts the dissolution behavior of boehmite by subjecting dry nanoparticles different sizes to
The generation and stabilization of gamma radiation-induced hydrogen atoms in gibbsite (Al(OH) 3 ) nanoplates is directly related to the nature residual ions from synthetic precursors used, whether nitrates or chlorides.
Ceramic materials display several desirable characteristics for nuclear energy applications, and thus, understanding how they behave in a radiation field, particularly accident scenarios, is necessary their successful implementation. This work investigates the role of interfacial water on radiolytic processes occurring at surface silicon zirconium carbides nitrides. Modification surfaces effect those H2 production are investigated. All studied were found to have layer oxidation surface, this...
