Amorphous computing considers the problem of controlling millions of spatially distributed unreliable devices which communicate only with nearby neighbors. To program such a system, we need a highlevel description language for desired global behaviors, and a system to compile such descriptions into locally executing code which robustly creates and maintains the desired global behavior. I survey...

By analyzing first-principles molecular-dynamics simulations of different telluride amorphous networks, we develop a method for the enumeration of radial and angular topological constraints, and show that the phase diagram of the most popular system Ge-Sb-Te can be split into two compositional elastic phases: a tellurium rich flexible phase and a stressed rigid phase that contains most of the m...

A mullite-supported Rh catalyst with an unusual crystalline structure in favour of high-temperature reactions was applied for the first time to the catalytic decomposition of N(2)O propellants, and has shown a promising initial activity and thermal stability.

The aim of this in vitro study was to evaluate the effect of silica and aluminosilicate nanocomposite coating of zirconia-based dental ceramic by a sol-gel dip-coating technique on the bond strength of veneering porcelain to the yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) in vitro. Thirty Y-TZP blocks (10 mm ×10 mm ×3 mm) were prepared and were assigned to four experimental groups...

Vapor-deposited Zr-Fe multilayered thin films with various wavelengths and of overall composition either 50% Fe or Fe-rich up to 57 % Fe were either irradiated with 300 keV Kr ions at temperatures from 25K to 623 K to fluences up to 2 x 10l6 cm-2, or simply annealed at 773K in-situ in the Intermediate Voltage Electron Microscope at Argonne National Laboratory. Under irradiation, the final react...

Hollow spheres of MCM-41 mesoporous aluminosilicates, with two small holes on the shell, have been synthesized from a surfactant-aluminosilicate gel composite.
