A range of synthetic carbonated apatites were characterized using infrared and Raman spectroscopy, X-ray diffraction, and chemical analysis and compared to stoichiometric hydroxyapatite and dental enamel. Synthetic apatites were prepared by aqueous precipitation and by solid-state reaction at high temperatures. A meth…
The phase diagram of the C12H25(OCH2CH2)5OH/water/tetradecane system was studied around the critical solution temperatures of surfactant-water and surfactant-oil phases. Although the phase behavior is very complicated due to the formation of liquid crystalline phase, basic phase-changes around the three-phase region,…
Studies of radiation damage in crystalline insulators usually originate from problems connected with heavy ion impact during ion bombardment, from neutron irradiation with and without fission in nuclear reactors, or from α-decay with the resulting damage due to recoil daughter atoms of the decaying nuclei of actinide…

Description This publication is divided into five major subject areas: Creep and Swelling; Microstructural Development; Pressure Vessel Steels; Mechanical Properties; Charged Particle Irradiation; Theory of Radiation Effects.
Molybdenum alloyed austenitic stainless steels were exposed in 0.1 M HCl + 0.4M NaCl and polarized in the active and passive regions of the alloys. The treated surfaces were analyzed by utilization of the electron spectroscopy for chemical analysis (ESCA) method. The reaction products formed on the surface after passi…
The stability of weakly incommensurate two-dimensional solid phases described by periodic arrays of discommensurations has been investigated. It is shown that incommensurate phases consisting of a small number of possible commensurate domains of either the striped or honeycomb type are unstable with respect to the spo…
It is shown that the crystal lattice expansion of microcrystalline silicon leads, in the limit of small crystallite size of about 30 Å, to an instability of the diamond structure with respect to the amorphous phase. Simple thermodynamic considerations are presented which support the idea of the crystalline-to-amorphou…

A burst criterion model has been developed to calculate the burst data of Zircaloy claddings of a pressurized water reactor in a loss-of-coolant accident. It is assumed by this model that the time of burst is reached when the local stress equals the limiting burst stress. The burst stress is assumed to depend on the t…
The first examples of electrochemical doping of poly-(p-phenylene) to form n- and p-type complexes with counter ions such as Li+ and AsF6– are reported; polyphenylene can be used as the electroactive material in rechargeable battery electrodes.
The immobilized dimers of glyceraldehyde 3-phosphate dehydrogenase have been obtained after dissociation of the tetrameric enzyme molecule linked by one of the subunits with Sepharose 4B. The catalytic parameters (V, Km and pH-dependence of activity) of the immobilized dimers and tetramers of the enzyme are identical.…
Constitution, microstructure, cooling–transformation (CT) diagrams, and corresponding diagrams for mechanical properties are summarized for the Cu–Al–X alloy types (X = Fe, Ni, Mn, Be, Co, Si, and Sn) with β-transformation. On the basis of the cooling time, it is possible to simulate the micro-structure and the proper…
Rapid perturbation of the 1A ⇌5T equilibrium in several Fe11 complexes occurs upon irradiation in the metal-to-ligand charge-transfer absorption region of the low-spin state, providing primary evidence for the formation of a 5T ligand field state from the initially populated charge-transfer state and permitting study…
The partitioning of aluminium between silicate melt (olivine tholeiite) and chromian spinel was studied experimentally. Runs were carried out at temperatures of 1 180˗1 300 °C and oxygen fugacities of 10⁻⁷˗10⁻⁹ atmosphere, at one atmosphere total pressure. The Al₂O₃ content of spinel is related to the Al₂O₃ content of…

Detailed measurements of the resistivity and the Hall coefficient have been made on high-quality single crystals of 2 H metallic transition-metal dichalcogenides between 4.2 K and 300 K, in order to investigate the carrier scattering mechanisms in a CDW system. The resistivity of 2 H -NbS 2 , which has no CDW transiti…
