Anomalous dissolution behaviour of tablets prepared from sugar glass-based solid dispersions
Journal of Controlled Release, 2004In this study, anomalous dissolution behaviour of tablets consisting of sugar glass dispersions was investigated. The poorly aqueous soluble diazepam was used as a lipophilic model drug. The release of diazepam and sugar carrier was determined to study the mechanisms governing dissolution behaviour.

Anomalous kinetic roughening during anodic dissolution of polycrystalline Fe
Physical Review E, 2008Dynamics of surface roughness during polycrystalline pure iron electrodissolution is investigated at constant current density by means of ex situ atomic force microscopy. The scaling of the local surface width reveals that surface kinetic roughening is anomalous with both the exponents of local roughness, alpha(loc) , and growth, beta , close to 1 ...

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

Complex Dynamics during Metal Dissolution: From Intrinsic to Faceted Anomalous Scaling
Physical Review Letters, 2009The kinetic roughening of dissolving polycrystalline pure iron has been studied. A depth analysis of surface images has shown two consecutive growth regimes characterized by different scaling anomalous properties: an initial intrinsic anomalous scaling evolving in the thick film limit towards the theoretically conjectured faceted anomalous scaling ...

Transition from anomalous kinetics toward Fickian diffusion for Si dissolution into amorphous Ge [PDF]
Applied Physics Letters, 2008 Over the last years, several experimental and theoretical studies of diffusion kinetics on the nanoscale have shown that the time evolution (x∝tkc) differs from the classical Fickian law (kc=0.5). However, all work was based on crystalline samples or models, so far.

On the role of the anions on the anomalous anodic dissolution of aluminium
Journal of Applied Electrochemistry, 1977The influence of the anions on current efficiency during the anodic dissolution of aluminium, and on the surface state of the electrode, has been studied both from a theoretical and an experimental point of view. The results obtained have some implications both in the field of electropolishing and in the field of electrochemical machining.

Anomalous Electrochemical Dissolution and Passivation of Iron Growth Catalysts in Carbon Nanotubes
Langmuir, 2007Catalytically synthesized carbon nanotubes (CNTs) such as those prepared via chemical vapor deposition (CVD) contain metallic impurities including Fe, Ni, Co, and Mo. Transition metal contaminants such as Fe can participate in redox cycling reactions that catalyze the generation of reactive oxygen species and other products.
