Mechanism of morphology transformation during annealing of nanostructured gold films on glass.

Physical Chemistry, Chemical Physics - PCCP, 2013
Nanostructured, just-percolated gold films were prepared by evaporation on bare glass. Annealing of the films at temperatures close to or higher than the softening temperature of the glass substrate induces morphological transformation to discrete Au ...

Annealing in spin glasses

Journal of Magnetism and Magnetic Materials, 1980
Abstract It is suggested that the magnetic atoms of a spin glass are not randomly distributed in the lattice and may even migrate below the freezing temperature. This can explain why scaling is incorrect and also explains magnetic remanence.

Nonlinear Annealing of Glass

Journal of the American Ceramic Society, 1981
Transient as well as residual stresses were measured in laboratory experiments on annealing by nonlinear cooling schedules. The data on transient stresses, in particular, were incompatible with a classical view of annealing but they could be explained by a more recent model of annealing, in which account is taken of structural as well as stress ...

The identification of toughened glass by annealing

Forensic Science International, 1982
Abstract An annealing routine was devised that produced RI changes in various glasses. When applied to 40 window, 20 non-window and 25 toughened windscreen glasses the toughened material could be distinguished from the other types. This procedure could improve the evidential value of glass for ‘hit and run’ accidents.

Annealing and tempering of glass

Journal of Non-Crystalline Solids, 1990
Abstract The main contributions to the theories and modeling of annealing and thermal tempering of glass are described in chronological order. The bases of several interesting annealing processes are mentioned. Finally, an assessment is made of the state of progress in the use of numerical methods for modeling tempering and annealing processes.

RELATION BETWEEN INELASTIC DEFORMABILITY AND THERMAL EXPANSION OF GLASS IN ITS ANNEALING RANGE

, 1946
In accordance with experience concerning the behavior of glass at temperatures within its annealing range, an equation is proposed which relates the various extraordinary heat effects to the inelastic deformability and to the degree of superheating or ...

Laser annealing of phosphosilicate glass

Journal of Vacuum Science and Technology, 1981
Laser annealing of CVD layers of phosphosilicate glass (PSG) using a CO2 laser (10.6 μm wavelength) has been investigated. Evidence of plastic flow of the PSG caused by laser heating was obtained. Reduction of surface and bulk defects in the PSG layers was ascertained by measurement of scattering losses, before and after annealing, of He–Ne radiation ...

Fine Annealing of Optical Glass

Journal of the American Ceramic Society, 1954
Since the most important characteristic of optical glass is the uniformity of its refractive index, which is itself a function of fictive temperature, any fine annealing treatment must be such as to bring about substantial uniformity in fictive temperature. Methods of accomplishing this are reviewed.

Measurement of the refractive index dispersion of As2Se3 bulk glass and thin films prior to and after laser irradiation and annealing using prism coupling in the near- and mid-infrared spectral range.

Review of Scientific Instruments, 2011
The prism coupling technique has been utilized to measure the refractive index in the near- and mid-IR spectral region of chalcogenide glasses in bulk and thin film form.

ELECTRIC ANNEALING OF GLASS*

Journal of the American Ceramic Society, 1932
ABSTRACTThe total and distribution heat requirements are discussed in general as well as the manner in which electric leers economically meet these requirements based on actual determinations and calculations.
