In this work, the thermal reaction of aluminum (Al) and nickel oxide (NiO) was investigated by molecular dynamics simulations. Some effective features of reaction such as reaction temperature, the reaction mechanism, and diffusion rate of oxygen into aluminum structure were studied. ReaxFF force field was performed to study the Al/NiO thermite reaction behavior at five different temperatures (5...

With the aim of developing a process for surface enlargement on an electrode for measuring brain activity attempts have been made to fabricate a porous anodic alumina membrane directly on the electrode. The porous membrane was intended to be used as scaffold for deposition of an electrically conducting polymer on the electrode surface. A silicon wafer with gold electrodes was the base onto whic...

-. Secondary electron yield measurements before and after Ar ion sputter cleaning were made on Nb and Nb compounds of interest for rf superconducting cavities. Total secondary electron yields (a) for primary energies 20-1500 eV were measured for solid Nb (a max = 1.3 at 300 eV), anodized NbzOs (a max = 1.2 at 300 eV) and powders of: Nb(a max = 1.0 at 400 eV), NbO (a max = 0.9 at 400 eV), NbOz (...

The tunneling magnetoresistance sTMRd of thin dielectric tunnel barriers that are sandwiched between pairs of ferromagnetic metal thin films is highly sensitive to the barrier layer atomic scale thickness, the uniformity in thickness, and the composition. Widely used AlOx barriers are formed by the oxidation of 1–2 nm thick aluminum layers vapor deposited onto one of the ferromagnetic metal ele...

The lap shear strength of chromic acid anodized, primed, Ti-6Al-4V alloy bonded with a high performance FM-5 polyimide adhesive has been investigated as a function of thermal treatment for selected times at various temperatures in air. The research findings indicate that the lap shear strength decreases with the increase in duration of the thermal treatment at constant temperature and with the ...
