Measurement of Fracture Surface Energy of SiC
The fracture surface energies of 5 polycrystalline silicon carbides were measured at room temperature using the double‐cantilever‐beam, notched‐beam, and work‐of‐fracture methods. All methods yielded comparable fracture surface energies,
Effect of Oxide Defect Structure on the Electrical Properties of ZrO 2
The defect structure of monoclinic ZrO 2 was studied by measuring the transfer numbers and electrical conductivity as functions of O 2 pressure and temperature. The data suggest a defect structure of doubly ionized oxygen vacancies at low pressures, i.e. <10 −19 atm, and singly ionized oxygen interstitials at press…
Laboratory Flow Characteristics Of Gun Perforations
Flow rates through gun perforations calculated for radial-flow conditions and confirmed in laboratory tests indicated perforation efficiencies substantially lower than those observed in API RP 43 tests with linear-flow test targets. Observed perforation efficiencies were also strongly influenced by differential pressu…
Ultrastructural Similarities Between Setae of Brachiopods and Polychaetes
Larvae of the brachiopod Terebratalia transversa Sowerby have 2 bundles of setae on each side of their mantle lobe. Each seta grows out of a follicle of epidermal cells. The cisternae and associated vesicles of the Golgi bodies in lateral follicular cells are filled with electron dense material. The basal follicular c…
The plasma polymerization of vinyl monomers. I. The design, construction, and operation of an inductively coupled plasma generator and preliminary studies with nine monomers
Abstract An apparatus was constructed which would allow vinyl‐type monomers (and others) to polymerize at ambient temperatures in the presence of an inductively coupled RF field. The details of the construction of the system are reported along with preliminary results obtained from nine monomers: styrene, methylvinyld…
Underwater Light-Beam Propagation in the Small-Angle-Scattering Approximation
The radiance N, resulting from an initially narrow collimated beam, propagating in the ocean, is investigated with the aid of the small-angle-scattering theory of electron scattering. The resulting expression for N is calculated approximately and compared both with experiments and numerical calculations. Various prope…
Easy directions of magnetization in ternary R<inf>2</inf>(Co, Fe)<inf>17</inf>phases
The magnetocrystalline symmetry and the Curie temperature of six families of quasi-binary rare earth-cobalt-iron intermetallic phases were studied. Investigated were the phases R2(Co1-xFex)17of the light rare-earth elements R = Ce, Pr, Nd, Sm, and Y and also of Ce-rich mischmetal (MM). In the Sm system, the terminal c…
Like-sign asymmetric dislocations in zinc-blende structure
Symmetry considerations reveal that an asymmetry exists relative to orthogonal 60° dislocations of the same sign in zinc-blende structure. The effect of this asymmetry has been observed in compositionally graded crystals of In1−xGaxP and GaAs1−xPx grown from vapor phase. It is observed that the spatial arrangement of…
Rheological properties of poly(2,6‐dimethylphenylene oxide)—polystyrene blends
Abstract The viscoelastic (VE) response of freeze‐dried blends of polystyrene (PS) and poly‐(2,6‐dimethyl phenylene oxide) (PPO) has been studied as a function of composition, frequency, and temperature to examine the degree of rheological compatibility. When blended together, the relaxation processes of both molecula…
Méthode directe de correction des profils de raies de diffraction des rayons X. III. Sur la recherche de la solution optimale lors de la déconvolution
Solutions of the convolution equation are given. A rigorous mathematical treatment shows that only one solution is consistent with the physical conditions. Application of these results to discrete examples has been carried out by means of an original deconvolution method, allowing isolation of the unique solution, and…

Kinetics of Domain Wall Motion in Ferroelectric Switching. I. General Formulation
Detailed theoretical study has been made of the nucleation model for wall motion in ferroelectrics. Kinetics of the wall motion has been worked out both analytically and by simulation. The wall velocity v is expressed in terms of nucleation rate I and sideways growth velocity u s of nuclei on the wall by the formula v…
Surface crosslinking of polyethylene using a hydrogen glow discharge
Abstract Linear high‐density polyethylene is crosslinked by exposing it to a hydrogen glow discharge and alternatively by exposing it to a low‐pressure Hg–A ultraviolet lamp in a dry nitrogen atmosphere. For the UV lamp case, the crosslinked gel is measured as a function of the radiation dose. For the plasma case, the…
Regular point processes and their detection
A class of point processes that possess intensity functions are studied. The processes of this class, which seem to include most point processes of practical interest, are called regular point processes (RPP's). Expressions for the evolution of these processes and especially for their joint occurrence statistics are d…
Effective Degree of Immobilization of Rubber Occluded within Carbon Black Aggregates
Abstract The conclusions of the present work may be summarized as follows. 1. The effective volume of carbon black in rubber, as measured by the low-strain equilibrium modulus, is equal to the true volume of carbon plus about half of the occluded volume of rubber calculated from the DBP absorption of the carbon black.…
The dynamics of disordered lattices
This article reviews the theory of atomic vibrations in disordered solids, ranging from almost perfect crystal lattices to glassy materials where geometrical regularity is entirely absent. As a preliminary, the basic notations and equations of conventional lattice dynamics are briefly outlined; the essential equivalen…
Secondary electron emission due to primary and backscattered electrons
Based on a simple atomic model giving the potential between electrons and atoms as V ( r )= Ze 2 a s −1 / sr s , the range of electrons penetrating solid targets is derived. Starting from the generalized power law involving the energy loss, the Lenard-type absorption law, and the assumption that the distribution of th…
