Dissolution of silver nanotubes in glass through an intense de electric field

Article Abstract:

Silver nanoparticles within a glass matrix could be destroyed and dissolved in the glass in the form of silver ions by applying a combination of an intense direct current (dc) electric field and moderately elevated temperature. The nanoscopic processes leading to this effect are discussed and it is demonstrated that the technique allows one to produce optical structures down to the submicron scale, making it suitable for design of several optical and optoelectronic elements.

Calorimetric features of high-enthalpy amorphous solids and glass-softening temperature of water

Article Abstract:

The glass softening endotherm is interrupted by the crystallization exotherm, in the differential scanning calorimetry (DSC) scans of the annealed states of vapor-deposited, hyperquenched, and crystal-amorphized solids. The studies of hyperquenched kinetically frozen states of high fictive temperature of proteins would be valuable in investigating various stages of protein transitions.

Morphological changes of silver nanoparticle distributions in glass induced by ultrashort laser pulses

Article Abstract:

The permanent optical changes induced by femtosecond laser pulses in glass containing silver nanoparticles could be unambiguously correlated with significant changes of the nanoscopic distribution of silver within the glass matrix. At low intensities, the changes of the extinction band exhibit no polarization dependence.
