Materials sliding on a larger substrate age faster than the substrate itself, but no available model of friction takes into account this aspect. We developed a model based on the memory effect of both the mobile and the plane samples, separately, and characterized by macroscopic geometric measurements (e.g., sliding distances and samples sizes). We studied the contact between fresh paper samples and samples that have already underwent several slidings. Experimental and theoretical results are in good agreement. Finally, we used our model to demonstrate how the existing test methods can lead to differences in the measured forces of friction. The results allow both a better understanding and quantitative characterization of the dependence of friction with the history of the contact. [ABSTRACT FROM AUTHOR]

The article focuses on the use of design of experiment (DoE) approach for photographs and paper works which may get damaged by the environmental changes. It discusses the need for controlling the environmental factors like relative humidity (RH) and temperature, how the research information gathered have made it possible to recommend materials for framing of photographs and paper in museum collection. It also talks about the use of Mavelseal, which can help to reduce the humidity fluctuations with marginal costs.
