The fatigue life of microcellular polycarbonate specimens of five different relative densities ranging from 0.52 to 0.97 was measured in tension-tension tests on dumbbell specimens. Fatigue life varied with relative density and maximum nominal cyclic stress. The fatigue life of microcellular polycarbonate with relativ…
Abstract Carbothermal reduction kinetics to synthesize SiC is studied under conditions of high carbon/silica precursor heating rates (10 5 K/s) and minimized reaction times (s) over a wide temperature range (1,848⩽T⩽2,273 K). The reaction mechanism includes rapid formation of a gaseous SiO intermediate. Further carbon…
Crystallization of BaTiO 3 from an X‐ray amorphous, metal organic precursor was investigated by comparing samples heated in O 2 , air, argon, and CO 2 . It is evident that an intermediate barium titanium oxycarbonate phase forms between 500° and 620°C and that BaTiO 3 forms directly by the endothermic decomposition of…
Shape transformations of two-compoent vesicles in which the spontaneous curvature depends on the local compositions in the two monolayers are investigated theoretically. Even if the two components do not exhibit lateral phase separation in spherical vesicles, temperature-induced shape transformations cause lateral pha…

In order to study the structural properties of water at interfaces, we performed neutron scattering experiments of water confined inside interconnected pores of Vycor glass. The structure factors and the corresponding radial distribution functions of the confined water have been determined as a function of temperature…

A statistical model is proposed to address the problem of two-phase coexistence near the morphotropic phase boundary (MPB) in Pb(${\mathrm{Zr}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Ti}}_{\mathit{x}}$)${\mathrm{O}}_{3}$ solid-solution series. Functional forms for the molar fractions of tetragonal and rhombohe…
Just before the turn of this century, physicists were impressed with their abilities to explain many of the basic laws of the universe mathematically.However, the energy output spectrum of a heated black body resisted rigorous explanation, particularly at the shorter wavelengths.This failure of classical physics was r…

Plasma etching in conjunction with scanning and analytical transmission electron microscopy was used to characterize the microstructure and microchemistry of silicon carbide sintered with yttrium‐aluminum garnet (YAG). The SiC grains comprise a core/rim structure with small amounts of excess yttrium, aluminum, and oxy…
In the present paper a review is made about the works and researches related to the use of superficial protectants for the stones conservation in Spain. It deals with the parameters and durability tests most frequently used in laboratories, in order to foretell the suitability of the different treatments. It is also p…
This paper presents the state-of-the-art on hydraulic behaviour of the blast furnace slags. It analyzes different aspects such as characteristics and influence of its vitreous phase structure, its chemical composition, mechanisms that rule its hydration process, activators and activating process mechanisms, etc. At th…
