Abstract 1. The systematic relations of the oxidation of SKB under the action of heat, light, and ionizing radiation are considered and it is shown that the formation of a series of oxygen-containing products takes place (hydroperoxides, alcohols, aldehydes, ketones, acids, ethers, and esters). The general tendency fo…

The far ultraviolet absorption spectra of Ce and Eu is reported and discussed. The relatively broad and weak electron transfer bands were found to have the lowest wave-number in the most oxidizing central ion, Eu(III). A solution of 0.03 M Eu(III) perchlorate in 0.1 M HClO4 shows a maximum at 188 m mu , with the molar…
Structures and unit-cell dimensions for a number of alloys of TiFe2–ZrFe2 and of ZrCo2–ZrFe2 have been determined at room temperature, and the magnetic properties of alloys of the two systems have been investigated over a range of temperature extending from 4° to 650°K. Results for the TiFe2–ZrFe2 system show two term…
Stress‐strain data for single crystals of MgO tested in compression with 〈110〉 and 〈111〉 loading axes are presented for temperatures ranging from 26〉 to 1250°C. Stress‐strain data for polycrystalline MgO are also presented over the same temperature range. Single crystals with a 〈111〉 loading axis were found to deform…
The liquidus, solidus, and subsolidus of the system CaO–MgO have been redetermined. X‐ray diffraction and optical techniques show that the maximum solid solution of MgO in the CaO lattice is approximately 17 wt% at 2370°C and the maximum solid solution of CaO in the MgO lattice is approximately 7.8 wt% at 2370°C. The…
A powder neutron diffraction study has been made on the intermetallic compound, FeSi. From magnetic measurements this substance has been believed to be antiferromagnetic below 170°C. Neutron diffraction measurements at room temperature and at liquid nitrogen temperature, however, show no coherent antiferromagnetic int…

Abstract Considerable interest has been focused in recent years on the effects of carbon black surface chemistry on its properties in rubber and other polymer systems. Methods have been developed in our laboratory for the quantitative characterization and description of the surface chemistry of carbon blacks. The tota…
Abstract Sulfenamide—sulfur curing systems containing zinc oxide and stearic acid respond to both ionic and radical reaction conditions. Scorch delay and rate of the vulcanization are determined by the basicity and steric structure of the amine forming the amide, and by the accelerator-sulfur ratio. Sulfenamides deriv…

It has been shown that in zone-refined aluminium, under specific quenching conditions, regions of stacking fault bounded by dislocation loops with a 1/3 [111] Burgers vector can be formed. The same type of defect can be produced by multiply quenching 99•995% aluminium. Repeated quenching therefore produces effects sim…
Abstract The mechanics of extension of plant fibers is considered in terms of a spiral arrangement of crystalline fibrils embedded in a noncrystalline matrix. Deformation may take place either by stretching of the fibrils or by extension such as that of a spiral spring. In the latter, the major resistance comes from t…
Rapid diffusion along dislocation cores generally enhances the average bulk diffusion in a dislocated crystal. If each diffusing atom has at least several opportunities to make rapid excursions along various dislocation cores, Hart has shown that DT/DT0 = 1+fDP/DT0. DT is the average bulk diffusivity, DT0 is the diffu…

Since aluminum and germanium are two of the most easily incorporated impurities in crystalline quartz, the relationship of the color centers produced by x irradiation to these elements has been studied extensively. Previous work based on irradiation at 300°K has indicated that one type of electron-deficient center is…
The results are reported of calculations on H, H2, He, Be, N, and NH in bases of Gaussian elementary atomic orbital functions. Such functions, though physically less satisfactory than the customary Slater exponential functions, have the advantage that all integrals can be evaluated exactly by closed analytical formula…
