Examination of biodegradability of poly(ethylene carbonate) and poly(propylene carbonate) in the peritoneal cavity in rats.
The biodegradability of poly (ethylene carbonate) and poly (propylene carbonate), synthesized from carbon dioxide and alkylene epoxides, was investigated. The biodegradation of poly (ethylene carbonate) pellets in the peritoneal cavity in rats was observable 2 d after implantation and was nearly completed within 2 wee…
A spectroscopic investigation of cerium molybdenum oxides
A detailed X-ray photoelectron, i.r., and Raman spectral study has been made of Ce2(MoO4)3 and five novel cerium molybdenum oxides (α- and β-Ce2Mo4O15, β- and γ-Ce2Mo3O13, and Ce8Mo12O49), which are of particular interest as they are closely related to the cerium molybdenum oxide species which are expected to play an…
Creep of Zirconium Alloys in Nuclear Reactors
Description This book is aimed at the practicing engineer who is involved with the design, fabrication of operation of zirconium core components. The Metals Properties Council, as part of its continuing role of collecting, analyzing, and updating materials properties data, has arranged for the preparation of this book…
Radiation-induced swelling and amorphization in Ca2Nd8(SiO4)6O2
Specimens of Ca2Nd8(SiO4)6O2 were doped with 1.2 wt% 244Cm and the effects of self-radiation damage from alpha decay were determined as a function of cumulative dose. The macroscopic volume of the specimens increased exponentially with dose to a limiting (saturation) value of ∼8.0%. The initially crystalline material…

Grain-boundary diffusion in metals
The available models for grain-boundary diffusion are reviewed together with the relevant mathematical techniques for extracting the grain-boundary diffusivity from the various types of experimental data. The more useful experimental techniques are described, fo11owed by a presentation of results that shed light on th…
Radiation enhanced diffusion in UO2and (U, Pu)O2
The radiation enhanced diffusion (coefficient D*) of U-233 and Pu-238 in UO2 and (U, Pu)O2 with 2.5 and 15% Pu was measured during fission in a nuclear reactor. Normal diffusion sandwiches with a thin tracer layer were used. A radio-frequency furnace allowed the temperatures to be varied between 130 and 1400°. Neutron…
Mechanism of impact pressure generation from spark-generated bubble collapse near a wall
This paper deals with a detailed experimental investigation on the collapse of a single spark-generated bubble near a solid wall and the mechanism of its induced impact pressure generation. By changing L//?max from 0.14 to 17.1, where L is the distance between the electrodes and the solid wall and /?max a maximum bubb…

The synthesis of a new 22 π-electron macrocycle: pentaphyrin
The first synthesis of pentapyrrole macrocycle analogous to the porphyrins is described.
Toxicity of some charged lipids used in liposome preparations.
The inhibition of 3H-thymidine incorporation into DNA of L1210 cells in culture by liposomes was used as an index of liposome toxicity. Inhibition of 3H-thymidine incorporation appeared to be dose dependent for some lipid compositions tested. The commonly used neutral lipids, phosphatidylcholine and cholesterol did no…
Studies of the thermal decomposition of βNiO(OH) and nickel peroxide by X-ray photoelectron spectroscopy
The thermal decomposition of both βNiO(OH) and ‘nickel peroxide’ have been studied by combining X-ray photoelectron spectroscopic (X.p.s.) studies of the solid with mass-spectrometric analysis of the gas phase. Through monitoring the O(1s) and Ni(2p) spectra of the as-prepared solids during decomposition, with simulta…
On estimators for the reduced second moment measure of point processes
For the reduced second moment measure of stationary point processes several estimators are presented. In order to show the most general conditions under which the estimators are applicable, some properties of non-stationary point processes are introduced making it possible to reduce the second moment measure as in the…
Electrochemistry of ruthenates. Part 1.—Oxygen reduction on pyrochlore ruthenates
The reduction of dioxygen to water has been investigated on ternary ruthenium(IV) oxides having the pyrochlore structure; in particular, compounds of the general form Bi2–2xPb2xRu2O7-y have been studied. Oxygen reduction on these materials appears to proceed by a rate-determining outer-sphere electron transfer, follow…
Modification of radiation damage microstructure by helium
Current experimental findings on the effects of helium on the evolution of radiation damage microstructure in metals at temperatures where vacancies are mobile are reviewed. It is shown that helium concentrations as low as a few parts per million promote the formation of cavities and dislocations, may increase or decr…
Heat Capacity and Other Thermodynamic Properties of Linear Macromolecules. VIII. Polyesters and Polyamides
Heat capacity of polyglycolide, poly(ε-caprolactone), poly(ethylene terephthalate), poly(ethylene sebacate), polyglycine, poly(L-alanine), poly(L-valine),nylon 6, nylon 6.6 and nylon 6.12 is reviewed on the basis of measurements on 35 samples reported in the literature. All heat capacity data are compiled and a set of…
A review of the stainless steel surface
The characteristics of the surface of various stainless steels are reviewed. The property of these alloys that makes them stainless is the formation of Cr2O3 on the surface. It has been found that this protective layer can be modified relatively easily by heating, abrading, chemical treatment, or ion bombardment. Modi…
Scaling theory of polymer adsorption : proximal exponent
We interpret some recent calculations of Eisenriegler, Kremer, and Binder [1], and related multi-critical results of Diehl and Dietrich [2]. They show that the monomer concentration profile Φ(x) for isolated polymer chains in a good solvent and in close proximity to an adsorbing wall exhibits a singular behaviour ; i.…
Polyetherimide: A new high‐performance thermoplastic resin
Abstract A new high‐performance amorphous thermoplastic, named polyetherimide, has been developed by the General Electric Company. This resin is characterized by high deflection temperature (200°C at 264 psi), high tensile strength and flexural modulus (480,000 psi), and very good retention of mechanical properties at…
