Copper Mg K α XPS Spectra from the Physical Electronics Model 5400 Spectrometer
Copper spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer (XPS) using unmonochromatized Mg Kα x rays and four pass energy settings corresponding to analyzer energy resolutions of 1.34, 0.54, 0.27, and 0.13 eV. The specimen was a high purity copper foil that was sputter-clea…
Nickel Monochromated Al K α XPS Spectra from the Physical Electronics Model 5400 Spectrometer
Nickel spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer (XPS) using monochromatic Al Kα at five pass energy settings corresponding to analyzer resolutions of 1.34, 0.54, 0.27, 0.13, and 0.067 eV. The specimen is a high purity 4 μm thick nickel foil (99.95%) obtained from…
First-principles study of Zn- and Se-stabilized ZnSe(100) surface reconstructions
We have carried out first-principles pseudopotential calculations to study the formation energies of various ZnSe(100) surface reconstructions. Both Zn- and Se-terminated models are treated, using as a guide the satisfaction of the electron counting rule (i.e., charge compensation at the surface by the filling of all…
Characterization of LiNiO2 by XPS
We report x-ray photoemission spectra (XPS) of lithium nickel oxide (LiNiO2). XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromatized Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV. We present…
Characterization of Electrochemically Prepared γ-NiOOH by XPS
We report x-ray photoemission spectra (XPS) of electrochemically prepared γ-NiOOH. XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromatized Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV. We pr…
A Thermomechanical Model for a One Variant Shape Memory Material
A model is examined for thermoelastic materials, such as those that display the shape memory and pseudoelastic effect. As is common with models for these materials, an internal variable is utilized which gives the phase fraction of austenite at the microstructural level within the continua. Evolution equations are dev…
Characterization of β-Ni(OH)2 by XPS
We report x-ray photoemission spectra (XPS) of beta-nickel hydroxide (β-Ni(OH)2). XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromated Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV. We prese…
Cold adaptation of proteins. Purification, characterization, and sequence of the heat-labile subtilisin from the antarctic psychrophile Bacillus TA41
The gene of subtilisin S41, an alkaline protease secreted by the psychrophile Bacillus TA41, encodes for a preproenzyme of 419 amino acids residues. The nucleotide sequence and NH2- and COOH-terminal amino acid sequencing of the purified enzyme indicate that the mature subtilisin S41 is composed of 309 residues with a…
Plasma modification of polymer surfaces for adhesion improvement
Polymers have wide-ranging applications in food packaging and decorative products, and as insulation for electronic devices. For these applications, the adhesion of materials deposited onto polymer substrates is of primary importance. Not all polymer surfaces possess the required physical and/or chemical properties fo…
The soil ionization gradient associated with discharge of high currents into concentrated electrodes
It has been known for many years that the grounding resistance of a concentrated electrode drops when it is subjected to a high current charge. This helps reduce the ground potential rise. The degree of the resistance depends on the magnitude of the ionization gradient of the soil E/sub o/. Based on both a theoretical…
