Bound Rubber and Carbon Black Reinforcement

Abstract: The first description of the bound rubber phenomenon was by Twiss in 1925, who made the observation that the resistance of carbon black-natural rubber mixes to solvents was related to improved mechanical properties. Boiry studied many of the factors influencing the insolubilization of NR by fillers including type and amount of fillers, and mixing and testing variables. In 1937 J. H. Fielding of Goodyear developed a so-called “bound rubber” test because of his interest in the possibility of chemical bond formation between fillers and rubber. During the start of the U.S. synthetic rubber program, Baker and Walker reported in 1945 an insolubilization of SBR when mixed with carbon black significantly greater than the amount of normal gel in the unfilled elastomer. They were also the first to report that the amount of gel increased with increasing molecular weight and that a selective adsorption of high molecular weight material occurred. Since that time, many investigations have confirmed these findi...

Oxygen reduced niobium oxides

Abstract: Methods to at least partially reduce a niobium oxide are described wherein the process includes heat treating the niobium oxide in the presence of a getter material and in an atmosphere which permits the transfer of oxygen atoms from the niobium oxide to the getter material, and for a sufficient time and at a sufficient temperature to form an oxygen reduced niobium oxide. Niobium oxides and/or suboxides are also described as well as capacitors containing anodes made from the niobium oxides and suboxides. Anodes formed from niobium oxide powders using binders and/or lubricants are described as well as methods to form the anodes.

Aggregation and growth of submicron oxide particles in flames

Abstract: Growth of aerosol particles in concentrated silica synthesis flames was measured by laser light scattering. Nitrogen adsorption was employed to characterize surface area. Throughout their detectible existence, the particles consist of flocs or aggregates which contain multitudes of smaller primary or protoparticles. Growth of these primary particles, controlled by fusion rate, is consistent with a classical coalescence model. The rate of aggregate growth is precisely described by a model based on Brownian collision frequencies. Experimental data corresponding to mean Knudsen numbers ranging from 0.3 to 6.0 reveal a shift from free-molecule to continuum behavior that is surprisingly sharp. Excellent agreement between theory and observations is, in fact, observed when the transition occurs at a point.
