An ion imprinted polymer (IIP) based on aniline-formaldehyde was synthesized and then modified with extra aniline as cross-linker in the presence and absence of Sr (II) as the template to produce ion imprinted poly(aniline-formaldehyde) (IIPAF) and non imprinted poly(aniline-formaldehyde) (NIPAF). The sorbent was characterized by Fourier Transform Infrared Spectroscopy and was used for solid ph...

In this research, adsorption experiments were carried out for removal of Basic Blue 41(BB41) dye from an aqueous solution, using coconut fiber particles (CFP) as a low-cost biosorbent. The characteristics of coconut fiber particles weredeterminedwith a scanning electron microscope (FE-SEM) and Fourier Transform Infrared (FTIR) techniques. The effects of initial pH, biosorbentdose, contact time,...

We present a computational study of the dynamic behavior of a Ziff-Gulari-Barshad model of CO oxidation with CO desorption on a catalytic surface. Our results provide further evidence that below a critical desorption rate the model exhibits a nonequilibrium, first-order phase transition between low and high CO coverage phases. Our kinetic Monte Carlo simulations indicate that the transition pro...

The present paper shows the results of a nucleation and crystallisation study of a Nafluorrichterite glass carried out by dynamic scanning calorimetry (DSC). The kinetic study was performed using different procedures (Kissinger, Matusita-Sakka and Kissinger-AkahiraSunose (KAS) methods), and the Avrami parameter was determined from the Ozawa and Malek approximations and the Malek equation. The r...

Switching dynamics of nanoscale ferroelectric capacitors with a radius of 35 nm were investigated using piezoresponse force microscopy. Polarization switching starts with only one nucleation event occurring only at the predetermined places. The switching dynamics of nanoscale capacitors did not follow the classical Kolmogorov-Avrami-Ishibashi model. On the basis of the consideration of two sepa...

Classical overall transformation kinetics theory for grain boundary nucleated transformations relies on the assumption that the parent phase grain size is uniform. In the present work the theory is adapted to deal with the case where there is a distribution in the size of the parent grains, as is often found in practice. It is demonstrated that the overall transformation rate is fastest when th...

Non-isothermal crystallization kinetics of polydioxanone (PDO), a polymer with well-established applications as bioabsorbable monofilar suture, was investigated by Avrami, Mo, and isoconversional methodologies. Results showed Avrami exponents appearing in a relatively narrow range (i.e., between 3.76 and 2.77), which suggested a three-dimensional spherulitic growth and instantaneous nucleation ...

We introduce intentional idiosyncratic play in a standard stochastic evolutionary model of equilibrium selection in bargaining games. We define intentional mutations as rare play of mixed strategies that are supported only on the set of strategies that would give the idiosyncratic player a higher payoff were sufficiently many others to do the same. In contract games intentional idiosyncratic pl...

We consider a class of quadratic potential games and prove that (simple symmetric) coarse correlated equilibria (as introduced by Moulin and Vial 1978) can strictly improve upon the Nash equilibrium payoffs (that can not be improved upon by correlated equilibrium a la Aumann). We fully characterise the structure of the coarse correlated equilibrium that achieves the maximum improvement possible...
