From a single crystal of manganese ferrite, specimen cores have been cut which are capable of supporting single domain walls. These cores have been proportioned in two ways, one favoring a movable (110) wall, the other favoring a wall system perpendicular to the (110) plane. The basic experiment consists in applying r…
The room-temperature optical transmission spectra of pure and doped SrTi${\mathrm{O}}_{3}$ crystals have been studied after heating them in oxygen and vacuum; spectral measurements were made in the quantum energy range from 0.1 to 3.4 ev.A blue color, with strong attendant absorption in the infrared, can be induced in…
To furnish a greater choice of film materials for application in optical multilayer coatings, the optical properties of evaporated rare earth compounds such as Y2O3, La2O3, Pr6O11, Nd2O3, Sm2O3, Gd2O3, LaF3, NdF3, and CF3 were studied in the wavelength region from 0.22 micron to 2 microns. The materials were evaporate…

Article Notizen: Über die Reaktion aluminiumorganischer Verbindungen mit Organo(poly)siloxanen. Alkylaluminiumsilanolate was published on February 1, 1959 in the journal Zeitschrift für Naturforschung B (volume 14, issue 2).
Abstract Previous work has demonstrated that the degree of crystal perfection in kaolinite can be correlated with many physical properties. In this paper some further relationships are shown, including surface area, base exchange capacity, total percentage of iron and titanium, and high-temperature mullitization. Surf…
The prediction, from dynamical considerations, that floating fibres may take up velocities intermediate between those of the back and front rollers is confirmed by high-speed photographic studies. The failure of Ichino and Kurosaki8 to observe such velocities is explained in terms of the experimental conditions select…
Further studies were made on the effect of the nature of the atmosphere on the wetting of gold and platinum by sodium disilicate at 1000°C. The gases were oxygen, nitrogen, carbon dioxide, helium, argon, water vapor, carbon monoxide, hydrogen, and several mixtures of some of these gases. Data reported were obtained in…

Abstract This paper reports on quantitative measurements of the small angle scattering of various rayons and ramie fibers as functions of moisture content using a three slit vacuum camera and monochromatic radiation. The scattered intensity was normalized on sample thickness and primary intensity through determination…

Structural studies on (Ba-Pb)(Ti-Zr)O 3 system were performed, and the phase diagram of the whole system was determined. In the vicinity of BaTiO 3 , low temperature phases are brought to room temperature by adding Pb and Zr. Substituting some amount of Pb by Ba in Pb(Ti-Zr)O 3 , Curie point becomes lower, but the mor…
Single crystals of isotactic poly-4-methyl pentene-1 were prepared from solution. The crystals were mostly flat squares with more or leas regular shapes. They consisted of thin square layers forming spiral terraces centred on screw dislocations. The molecules were found to be perpendicular to these layers. The same po…
In commercial practice, where temperatures are low, a number of commercially available materials are satisfactory as a container for molten aluminum. None of these, however, resists attack by aluminum in the temperature range 1800° to 2000°C. An investigation was conducted to find a material completely inert to alumin…

Fourteen selected metal ions were added to magnesium basic carbonate, and the MgO obtained after calcining was fired at various temperatures to determine the effect of the additives on the sintering behavior. The magnesia without additives showed rapid increase in density with firing temperature near 1200° C. The majo…
The carbon atom positions in uranium carbides have been determined from neutron diffraction data. UC is face-centered cubic with sodium chloride structure. U/sub 2C/sub 3/ is body-centered cubic with space group 14 bar 3d, and carbon atoms have one parameter of 0.295 with carboncarbon bond distance of 1.295 A. UC/sub…

The conditions influencing the onset of acoustically-induced cavitation in tap water have been investigated, with special attention to the effect of air-filled cavitation nuclei. Cavitation was induced by exciting an acoustic radial mode in the water in a spherical resonator at a frequency near 25 kc/sec. Air-filled n…
