    Notes: We consider chemical reactions which at equilibrium have multiple stationary states due to nonidealities of chemical species. When such reactions are included in a simple reaction mechanism open to mass flow, without autocatalysis or feedback steps, there may occur complex dynamics such as relaxation oscillations, as reported earlier for regular solutions. Here we consider both regular solution and ionic species (Debye–Hückel nonideality), show that chemical oscillations may occur arbitrarily close to chemical equilibrium, and trace the topological structure of the complex dynamics of relaxation oscillations, sustained oscillations, stable focus, and stable nodes to the multiplicity of equilibrium states, for stated constraints. Relaxation oscillations occur around an unstable stationary state which, on approach to equilibrium, connects to an unstable equilibrium state. Thus, there is no bifurcation to oscillations on removing the systems from equilibrium. Neither is there a region where linear irreversible thermodynamics is valid close to equilibrium. Earlier work on ionic systems is found to be in error.

    Notes: In Marangoni–Bénard convection with mass transfer from the air to the liquid, an experimental exploration of reflections of solitary waves at walls has been carried out. Mach stems are observed for small enough incident angles. Upon increasing the incident angle the stem disappears thus leading to regular reflections with, however, the angle of reflection being generally larger than the incident angle.

    Notes: Film stability and structure formation inside a liquid film containing colloidal particles are investigated by Monte Carlo (MC) numerical simulations and by analytical methods. The effective pair interaction between particles is calculated from the Ornstein–Zernike theory with Percus–Yevick closure. Consistent with the recent experimental observations and theoretical studies, these MC simulations reveal the phenomena of internal particle layering as well as inlayer structure formation. In particular, an ordered two-dimensional hexagonal structure is observed at a particle concentration of 37 vol% (instead of 43 vol% for the hard-sphere potential) when the effective pair interaction between particles is taken into account. Furthermore, the particles inside a layer "condense'' due to the attractive depletion force which leads to the formation of voids. The formation of such void structures results in the formation of "dark spots'' which have been observed in film thinning experiments. The calculated film structural disjoining pressure, created by the particles inside the film, is found to be in agreement with the experimentally measured force-distance curves using the surface force apparatus. © 1995 American Institute of Physics.

    Description / Table of Contents: Riassunto I confini tendono generalmente a stabilizzare uno strato liquido altrimenti instabile soggetto a vincoli termici. Si forniscono qui risultati riguardo il ruolo della dimensione orizzontale finita e della profondità di strato finita per uno strato di liquido soggetto a gradienti di concentrazione dell'agente attivo di superficie quando l'instabilità (sovrastabilità) tende a crescere nelle forme di onde longitudinali o trasverse indotte dall'effetto di Marangoni.
    Abstract: Резюме Границы обычно стабилизируют неустойчивые слои жидкости, на которые наложены термические воздействия. В этой работе анализируется роль конечных горизонтальнхы размеров и конечных размеров по глубине для слоя жидкости при наличии градиентов концентрации поверхностно-активного вещества, когда неустойчивость возникает в форме поперечных или продольных волн, обусловленных эффектом Марангони.
    Notes: Summary Boundaries generally tend to stabilize an otherwise unstable liquid layer subjected to thermal constraints. Here, results are provided about the role of the finite horizontal size and of the finite layer for a liquid layer subjected to gradients of surfactant concentration when instability (overstability) tries to set up in the form of transverse or longitudinal waves induced by the Marangoni effect.
