Anomalous Water Penetration in Al3+ Dissolution
The Journal of Physical Chemistry LettersThe physicochemical characterization of trivalent ions is limited due to a lack of accurate force fields. By leveraging the latest machine learning force field to model aqueous AlCl3, we discover that upon dissolution of Al3+, water molecules beyond the second hydration shell are involved in the hydration process.

Advanced Powder Technology, 2010
Abstract Spray-dried particles were prepared with α-glucosyl hesperidin (Hsp-G), a hesperidin derivative with enhanced water solubility, to improve the solubility profile of naringenin (NRG). Naringenin was used as a model hydrophobic polyphenol. The spray-dried sample of NRG in the presence of Hsp-G formed 3–4 μm spherical particles. Those particles

Anomalous dissolution of nickel during the anodic oxidation of NiZn and NiZn3 intermetallic phases
Protection of Metals, 2000A physicochemical model is proposed for the conjugation of partial processes of hydrogen evolution and nickel ionization through a common intermediate stage of the surface dissociation of water. The model describes anodic and anomalous dissolution of nickel from the individual and intermetallic NiZn and NiZn3 phases. The acceleration of these processes

Electrochimica Acta, 1997
In addition to single nickel crystals also nickel samples produced by dc and pr (pulse-reversal) plating were examined. As previously reported the true rate of dissolution of nickel in solutions containing oxygen was found to be as much as three times the electrochemical rate at the corrosion potential. When passivation was approached (spontaneously or

Chemical Geology, 1990
Abstract A new selective chemical dissolution procedure for geological samples has been developed: six components were separated, i.e. carbonate, metal, sulfide, oxide, silicate and HF-insoluble residue. A series of experimental parameters, e.g. reagent types, temperature, time and pH-value, in dissolving the various phases has been investigated. The

Two kinds of InAs/GaAs quantum dot (QD) structures are grown by molecular beam epitaxy in formation–dissolution–regrowth method with different in-situ annealing and regrowth processes. The densities and sizes of quantum dots are different for the two samples.

Low Temperature Physics, 1998
The kinetics of growth and dissolution of a new phase during phase separation and homogenization of solid He3–4He mixtures is studied experimentally. It is found that both these processes have different kinetics, while homogenization is ensured by an anomalously rapid transport of matter in the crystal.

Corrosion, 2004
Chromium corroding in deaerated aqueous solution of sulfuric acid (H2SO4; pH 1 to 3) produces Cr(II) and Cr(III) ions simultaneously in the ratio 7:1, as well as H2. The corrosion potentials of electrochemically activated chromium are determined by the electrochemical processes as expected according to the Wagner-Traud model. However, the real rates of

Anodic Dissolution of Metals—Anomalous Valence
1974When metals are dissolved anodically in aqueous and nonaqueous media, the weight of metal dissolved is sometimes greater than that calculated from Faraday’s law assuming normal oxidation states. Among several metals of industrial importance, Al, Be, Cd, Fe, Pb, Mg, Ti, and Zn exhibit this phenomenon.

Protection of Metals, 2001
Based on an idea about common intermediate particles, a physicochemical model of iron dissolution and hydrogen evolution is proposed. According to the model, the independence of the dissolution rate of a cathodically polarized metal of the potential is a particular case of chemically conjugate anodic–cathodic reactions.
