Corrosion of a SiC-C/SiC Composite in Environments with Na2SO4 Vapor and Oxygen
A Numerical Model of Yield Stress Fluid Dynamics in a Mixing Vessel
A numerical study is conducted on the behaviour of yield stress fluids in a mixing vessel equipped with anchor agitator in laminar regime. It is shown that extending a standard Carreau model of shear thinning fluid is a suitable practice. Validations versus Couette flow analytical solution are satisfactory. Main featu…

Synthesis and aqueous phase behavior of thermoresponsive biodegradable poly(D,L-3-methylglycolide)-block-poly(ethylene glycol)-block-poly(D,L-3-methylglycolide) triblock copolymers
Novel biodegradable thermosensitive triblock copolymers of poly(D,L-3-methylglycolide)-block-poly(ethylene glycol)-block-poly(D,L-3-methylglycolide) (PMG-PEG-PMG) have been synthesized. Ring-opening polymerization of D,L-3-methyl-glycolide (MG) initiated with poly(ethylene glycol) (PEG) and Ca[N(SiMe3)2]2(THF)2 provid…
Computerised Glow Curve Deconvolution using General and Mixed Order Kinetics
Some accurate glow curve fitting functions for general and mixed order kinetics glow peaks are proposed and discussed. These mathematical expressions are used together with peak search and non-linear minimisation algorithms in order to provide a fast glow curve deconvolution for those materials which cannot be well fi…
On geological interpretations of crystal size distributions: Constant vs. proportionate growth
Geological interpretations of crystal size distributions (CSDs) depend on understanding the crystal growth laws that generated the distributions. Most descriptions of crystal growth, including a population-balance modeling equation that is widely used in petrology, assume that crystal growth rates at any particular ti…
The influence of oxygen deficiency on the magnetic and electric properties of La0.70Ba0.30MnO3 −γ (0≤γ≤0.30) manganite with a perovskite structure
The crystal structure and the magnetic and electric properties of La0.70Ba0.30MnO3 − γ manganite (0≤γ≤0.30) with a perovskite structure were studied experimentally depending on the concentration of oxygen vacancies. The stoichiometric La0.70Ba0.30MnO3 compound (γ = 0) had cubic unit cell symmetry, which did not change…
Tissue Reaction to Polypyrrole-Coated Polyester Fabrics: An in Vivo Study in Rats
Electrically conductive polypyrrole is very attractive for tissue engineering because of its potential to modulate cellular activities through electrical stimulation. However, its in vivo behaviors have not been fully studied. This paper investigates the in vivo biocompatibility and biostability of PPy-coated polyeste…
Freshwater Red Algae of the World
The Journal of Phycology was founded in 1965 by the Phycological Society of America. All aspects of basic and applied research on algae are included to provide a common medium for the ecologist, physiologist, cell biologist, molecular biologist, morphologist, oceanographer, taxonomist, geneticist, and biochemist. The…
Conductive polymers as a new type of thermoelectric material
Thermoelectric properties were investigated for the films of electrically conductive doped polyanilines. The thermoelectric performance, evaluated by thermoelectric figure-of-merit (ZT = T (S2 σ) / κ), of various protonic acid-doped polyaniline bulk films was found to depend on the electrical conductivity σ of the fil…
Suppression of Quantum Phase Interference in Molecular Magnets Fe₈ with Dipolar-Dipolar Interaction
Renormalized tunnel splitting with a finite distribution in the biaxial spin model for molecular magnets is obtained by taking into account the dipolar interaction of enviromental spins. Oscillation of the resonant tunnel splitting with a transverse magnetic field along the hard axis is smeared by the finite distribut…
Extensional rupture of model non-Newtonian fluid filaments
We present molecular dynamics computer simulations of filaments of model non-Newtonian liquid stretched in a uniaxial deformation to the point of breaking. The liquid consists of Lennard-Jones monomers bound into chains of 100 monomers by nonlinear springs, and several different constant velocity and constant strain r…
Magnetic shape-memory effects in La2-xSrxCuO4 crystals
The magnetic field affects the motion of electrons and the orientation of spins in solids, but it is believed to have little impact on the crystal structure. This common perception has been challenged recently by ferromagnetic shape-memory alloys, where the spin-lattice coupling is so strong that crystallographic axes…
