Systematic studies of thermally induced structural transformations in the Na(,2)O.2SiO(,2) (,1-x)(.) Fe(,2)O(,3) (,x) glass system with x (LESSTHEQ) 0.3 have been carried out by means of a variety of techniques including ...

The mechanical property development associated with the healing of polymer-polymer interfaces was studied using theoretical and experimental approaches. The healing of crazes in atactic polystyrene (PS) and microvoids in ...

Thin film single crystal growth of metastable semiconducting (GaSb)(,1-x)(Ge(,2))(,x), Ge(,1-x)Sn(,x), and (GaSb)(,(1-x))(Ge(,2(1-y))Sn(,2y))(,x) alloys is studied as a function of growth parameters. The effects of low-energy ...

The deformation of thin films of polybutene (PB) and poly(vinylidene fluoride) (PVF$\sb2$) occurs by micronecking. Finite blocks are drawn off the edge of the microneck depending upon the orientation of the original ...

The dynamics of entangled polymer melts have been examined using polarized Fourier-Transform infrared (FT-IR) spectroscopy. Based on the reptation model, the motion of a chain in the presence of topological entanglements ...

Cu-Cr metastable alloys are interesting both from a basic science viewpoint (i.e., alloy theory for elements with very limited mutual liquid and solid solubilities) and from a technological viewpoint (i.e., "stainless" ...

Two separate experiments were performed in order to understand the roles of bulk diffusion and surface processes in hydrogen transport in and through niobium. Bulk hydrogen and deuterium diffusivities and permeabilities ...

A novel technique has been introduced to determine the film stress of metal silicon interfaced materials in-situ. This technique requires the use of a spatially wide yet highly collimated white beam of synchrotron radiation, ...
