A Stochastic Multi-scale Approach for Numerical Modeling of Complex Materials - Application to Uniaxial Cyclic Response of Concrete

open access: yes, 2016
In complex materials, numerous intertwined phenomena underlie the overall response at macroscale. These phenomena can pertain to different engineering fields (mechanical , chemical, electrical), occur at different scales, can appear as uncertain, and are

Relaxation Phenomena in a Bistable Chemical System

open access: yes, 1984
A theoretical investigation is presented of the relaxation dynamics of a simple model which gives a near-quantitative description of the iodate-excess arsenous acid systems (1). Near the hysteresis limits (K≳ K1, K≲ K2, K= input flow rate) and near the critical point K an exact expression is obtained for the nonlinear response to a sudden change of the

Langmuir Monolayer Studies of Phosphatidylcholine Membranes with Naproxen on the Polysaccharide Subphase

open access: yesMolecules
Natural polysaccharides are biocompatible and biodegradable; therefore, they can be widely used in drug delivery, tissue engineering and wound healing. In this context, the interactions between polysaccharides, drugs and biological membranes are of great

Effect of β-PVDF Piezoelectric Transducers’ Positioning on the Acoustic Streaming Flows

open access: yesMicromachines, 2014
This paper reports the numerical and experimental analysis of the acoustic streaming effect in a fluidic domain. The actuation of a piezoelectric transducer generates acoustic waves that propagate to the fluids, generating pressure gradients that induce ...

Resonant and crossover phenomena in a multiband superconductor tuning the chemical potential near a band edge

open access: yes, 2010
Resonances in the superconducting properties, in a regime of crossover from BCS to mixed Bose-Fermi superconductivity, are investigated in a two-band superconductor where the chemical potential is tuned near the band edge of the second mini-band ...

Normal state Nernst effect, semiconducting-like resistivity and diamagnetism of underdoped cuprates [PDF]

open access: yes, 2005
Semiconducting-like low-temperature in-plane resistivity indicates that there are no remnants of superconductivity above the resistive phase transition at T > Tc in underdoped cuprates.

Maze solvers demystified and some other thoughts

open access: yes, 2017
There is a growing interest towards implementation of maze solving in spatially-extended physical, chemical and living systems. Several reports of prototypes attracted great publicity, e.g.

Modification of Canola Oil Properties Using Ethyl Oleate and n-Hexane

open access: yesEnergies
Canola oil (rapeseed oil, RO), despite being a potential source of biofuel, needs some modifications of its properties to be effectively used as a fuel. The reason RO needs to be altered lies above all in its viscosity, fatty acid composition, and other ...

Publications of the exobiology program for 1984: A special bibliography [PDF]

open access: yes
A bibliography of NASA exobiology programs is given. Planetary environments; chemical evolution; organic geochemistry; extraterrestrial intelligence; and the effect of planetary solar and astrophysical phenomena on the evolution of complex life in the ...
