“…Оксиды переходных металлов слоистого строения (гексагональные оксиды молибдена и вольфрама, ксерогель оксида ванадия) представляют собой перспективные антифрикционные материалы, способные обеспечить существенное повышение износостойкости поверхности металлов в условиях сухого трения [1][2][3]. Отличительной особенностью смазывающих агентов такого рода является высокая химическая стабильность, позволяющая им функционировать в экстремальных условиях (в том числе в окислительных средах) при высоких механических нагрузках.…”

The effect of dispersed particles of lamellar molybdenum, tungsten and vanadium oxides on the lubrication properties of mineral oil was investigated. It is shown that in the presence of particles of hexagonal molybdenum oxide the coefficient of friction falls two-fold (from 0.08 to 0.04) exhibiting further decrease under high mechanical load, i. e. molybdenum oxide behaves as an adaptive lubricant. The intercalation of benzotriazole into molybdenum oxide ensures additional reduction of mechanical wearing due to suppressing the tribocorrosion.

“…Monolayer interfaces have found widespread use because of their potential utility in areas ranging from tribology, adhesives, and passivation of interfaces in device fabrication to the creation of biomimetic films. − The characterization of monolayer films is not simple, owing to the small number of molecules present and the propensity of many monolayer systems to produce nonuniform structures, especially in cases where multiple constituents are present. While there are a number of ways to characterize monolayer organization and overall uniformity, either spectroscopically − or electrochemically, − there remains to be established a way to understand compositional nonuniformities in these systems.…”

We report on the use of molecular diffusional motion over a range of length scales to characterize compositional heterogeneity in monolayer structures. This work focuses on the diffusional motion of perylene in two types of films supported on functionalized silica surfaces: single-component (stearic acid) and two-component (hydrocarbon/fluorocarbon) films. Langmuir-Blodgett (LB) monolayers were deposited directly on silica or were bound to surface-modified silica by means of metal ion complexation. The LB films were characterized by their π-A isotherms and by Brewster angle microscopy (BAM) during formation and deposition. Chromophore mobility and monolayer structural heterogeneity were evaluated by comparing rotational diffusion data (fluorescence anisotropy decay imaging) and translational diffusion data (fluorescence recovery after photobleaching) on the same LB films. Our results indicate that the mobility of the chromophore depends sensitively on both metal ion identity and film composition.
