“…Recently, porous nanostructures assembled from α‐MnO 2 nanorods were formed by a glucose–permanganate redox reaction in the presence of poly(ethylene glycol) (PEG) 15. Moreover, we have found that such a morphological structure was formed in our systems only at low concentrations of glucose solution, that is, 0.025 mol‐%, which indicates that the template behaviour of glucose in water is not likely to be effective in our systems although glucose may act as a template in water when at a concentration above 5 mol‐% due to the formation of different local structures 38. In addition the pore size and specific surface area of MN‐α‐MnO 2 could be modified by adjusting the reaction conditions (details are under investigation).…”

Mesoporous nanostructured α-manganese dioxide (MN-α-MnO 2 ) powders in a sponge-like three-dimensional network have been successfully synthesized in high yields in a simple, template-free manner at room temperature. Its unique structure has been found to be related to the glucose solution rather than to the KMnO 4 solution. A possible mechanism for the formation of MN-α-MnO 2 by the oxidation of MnO 2 precursors cross-linked by glucose networks is proposed that [a]

Key words metastable zone width, interfacial free energy, nucleation, growth from solution.This study presents an evaluation of a new method, called zero growth activation free energy, used to determine the metastable zone width for the secondary nucleation case. It predicts the metastable zone width with a maximum error of 5-10%. Estimation of the metastable zone width for different isothermal crystallization conditions can be modeled according to a chosen reference set of growth experiments carried out in the volume diffusion regime at different initial supersaturations, using seed crystals of a certain characteristic size. Moreover, the activation free energy of the secondary nucleation was estimated. The role of the enthalpy of immersion in the formation of secondary nucleation events inside the metastable zone was pointed out, as well as its effect in causing extra-fast growth rate. Furthermore, sucrose crystal surface free energy was estimated.
