The electrochemical, spectroscopic, and structural properties of passive layers on Ni(100) grown either electrochemically in aqueous 10 m M HClO 4 or by dosing with gaseous oxygen in ultrahigh vacuum (UHV) were compared using a UHV‐electrochemical transfer system equipped for x‐ray photoemission spectroscopy (XPS), lo…

The initiation and propagation of stress corrosion cracking (SCC) of high alloys in sour gas environments were investigated mainly from the viewpoint of cathodic reactions. The most probable cathodic reaction to support the metal dissolution in the pitting and/or cracking process was identified by means of electrochem…
Ethylenediamine, triethylenetetramine, 1,4‐bis(3‐aminopropyl)piperazine, and poly(ethylenimine) were individually chemisorbed onto an iron substrate. Chemisorption proceeded without new bands appearing in either the iron or oxygen photoelectron spectra, without the surface iron atoms being oxidized, and without either…

Abstract This paper discusses polymers for optoelectronics, especially plastic optical fibers (POFs) for near‐infrared (near‐IR) use and polymeric nonlinear optical materials expected for use as switching devices. Near‐IR transmissible plastic optical fibers are investigated using fluorination and deuteration for conv…

The carbon additions in the pressureless sintering of SiC are commonly used for the removal of SiO 2 layers on the starting powders. In practice, it is common to add more C than is necessary for stoichiometric removal to ensure a complete deoxidation. As a result, inclusions of excess free C are a general feature of t…
Smectic isotactic polypropylene films were annealed at different temperatures for different times. Density, wide-angle x-ray scattering (WAXS), differential scanning calorimetry, and the transport properties of methylene chloride vapor were used to follow the transformation of the smectic phase into the monoclinic pha…

Fine SiC powders were synthesized by burning the mixed reactionts Si and C in a nitrogen atmosphere of 3 to 10 MPa. The exothermic synthesis reaction propagated spontaneously after igniting the reactants at room temperature. The SiC powders obtained had a uniform size distribution of about 0.2 μm. The combustion veloc…

Although it is well established that small polarons are formed in transition metal oxide (TMO) glasses, no satisfactory quantitative analysis of d.c. and a.c. transport exists. The temperature dependences of the d.c. and a.c. conductivities for TMO glasses are re-examined. The charge transport cannot be explained quan…
Abstract Polypropylene, polystyrene, and polyethylene have been grafted with glycidyl acrylate and glycidyl methacrylate. After 5 min of grafting with UV irradiation, polystyrene was extensively grafted to 91% coverage of glycidyl acrylate according to ESCA, while polypropylene was grafted to only 50% coverage. With g…
Solar control characteristics of chemically deposited PbS and Cu x S thin films in the glass-PbS-Cu x S structure are reported. This combination offers pleasing colours: bluish, greenish, greenish-yellow etc in reflected daylight and low NIR transmittance-not possible with PbS-only coatings, while providing a high-eno…
Abstract The electronic band structure of CaS, SrS, and BaS is calculated by linear augmented plane waves (LAPW). The calculation is applied for the explanation of the optical properties of the alkalineearth‐metal sulphides.
