A pilot-scale corona reactor was adapted to process cotton sliver. Corona treatment improved cotton spinnability and increased yarn and fabric strength and abrasion resistance. Treatment effectiveness was greatest at 93-96°C with the injection of dilute chlorine gas into the corona cell. Dyeability was unaltered, cott…
Water dissolves in fused silica to give hydroxyl groups (OH) which give rise to a fundamental absorption band at 3700 cm−1. The reaction of water with silica may be represented formally as ≡Si-O-Si≡ +H2O→2≡Si-OH. Stevenson and Jack found the extinction coefficient of the above band was 77.5±5.1 mole−1 cm−1. Other less…
Six types of polycrystalline MgO, one nominally fully dense and the others having porosities of ∼1 to 2%, were tested in compression up to 1400°C. At 1200°C and above, all materials deformed plastically; two of the materials, both porous, also exhibited plastic flow at temperatures down to 800°C, and a third at 1000°C…
The lattice parameters of the cubic solid solutions from the system (U 1‐∞ Pu ∞ )N were measured at 25°C. The lattice constant, a 0 , of UN was 4.88918±0.00017 Å and that of PuN was 4.90476±0.00008 Å. The parameter of the solid solution does not depend linearly on the composition parameter, x. The X‐ray specimens cont…
Abstract Oxygen partial pressure in equilibrium with nonstoichiometric ceric oxide of a definite composition were determined by equilibration with pure oxygen, air, CO2, and CO2-H2 mixtures at 900, 1000, 1100, 1227, and 1300°C, using a thermobalance. The values for the activities and the relative partial enthalpies an…

The results of electrocaloric studies of the electrical equation of state of K${\mathrm{H}}_{2}$P${\mathrm{O}}_{4}$ in the temperature region within 1 K of the ferroelectric transition are reported. Chief emphasis is given to determination of the spontaneous polarization. A discontinuous polarization jump of 1.87 \ifm…
Abstract The specific surface area, the water content, and the water adsorption isotherm have been measured in order to investigate the interaction between the surfaces of SiO2, Al2O3, and SiO2·Al2O3 and water molecules. Al2O3 gives II-type adsorption isotherms and the amount of adsorbed water on it increases with a r…
We discuss some difficulties inherent to the light scattering measurement of the viscosity coefficients in paraazoxyanisol. In contrast with a previous report, we present a unique set for these quantities, in reasonable agreement with the conventional determination by Miesowicz.
Cross sections differential in angle and ejection energy for electron production by proton impact on nitrogen, oxygen, neon, and argon have been measured using electrostatic analysis and counting of individual electrons. The range of proton energies was 50-300 keV, the angles ranged from 10\ifmmode^\circ\else\textdegr…
Abstract Mixing effects for the homogeneous, liquid‐phase, second‐order, competitive‐consecutive reaction of iodine ( B ) with L‐tyrosine ( A ) to form 3‐iodo‐L‐tyrosine ( R ) and 3,5‐diiodo‐L‐tyrosine ( S ) were determined for the following conditions: vessel volume, 5 and 36 liters (baffled and unbaffled); turbine d…
The origin of the memory effect in Cu–14.2Al–4.3Ni (W/O) alloy has been investigated using the techniques of optical microscopy and electron microscopy. As a result the following have been established. The plastic deformation is caused by the growth or creation, and the contraction or disappearance of twins inside mar…
An electron optical system is described which is suitable for energy loss analysis in an electron microscope. A focusing spectrometer of the Wien type has been added underneath the column of a Hitachi HU11A electron microscope. After passing through the microscope, the electrons are slowed down before entering the spe…
Dielectric measurements are reported on capacitance thermometers based on SrTiO3 crystallized from glass at 1100 and 1200°C. Multilayer experimental units, approximately 5×2×1 mm, were fabricated using pilot plant facilities and measured from 1.7 to 300 K. If both the capacitance and loss tangent are measured, the ran…
A theory of melting with application to liquid crystals in which both translational and orientational order parameters are taken into account is developed in a manner similar to that of Kirkwood and Monroe.
