Fracture toughness of aged oil paints

Arkadiusz Janas, Nefeli Avgerou, M.N. Charalambides, Laura Fuster‐López et autres

Abstract The fracture toughness in opening mode G Ic for selected oil paints from Mecklenburg's Paint Reference Collection after approximately 30 years of natural ageing was determined using the procedure adopted from the ASTM D5528–13 standard in which double cantilever beam specimens …

Fracture toughness of dried oil paints

Arkadiusz Janas, Nefeli Avgerou, M.N. Charalambides, Laura Fuster‐López et autres

Abstract The fracture toughness in opening mode for selected dried oil paints was determined filling in this way a critical gap in the knowledge required for the analysis of fracturing processes in paintings. The experimental work was made possible by the adaptation …

Charge‐State‐Enhanced Ion Sputtering of Metallic Gold Nanoislands

Gabriel L. Szabo, Benedykt R. Jany, Helmut Muckenhuber, Anna Niggas et autres

Experimental results on the charge-state-dependent sputtering of metallic gold nanoislands are presented. Irradiations with slow highly charged ions of metallic targets were previously considered to show no charge state dependent effects on ion-induced material modification, since these materials possess enough free electrons …

Shrinkage and mechanical properties of drying oil paints

Arkadiusz Janas, Marion F. Mecklenburg, Laura Fuster‐López, Roman Kozłowski et autres

Abstract Understanding how the evolving molecular composition of an oil paint layer on its transition to an aged solid film affects its dimensional change and mechanical properties is fundamental to the assessment of material durability and more broadly risk of degradation of …

Mechanical properties and moisture-related dimensional change of canvas paintings–canvas and glue sizing

Arkadiusz Janas, Laura Fuster‐López, Cecil Krarup Andersen, Ángel Vicente Escuder et autres

Abstract Understanding canvas paintings as physical systems is fundamental to develop evidence-based environmental specifications for museums. A number of tests were carried out to determine mechanical properties of canvas, canvas sized with animal glue and animal glue-based ground layer (gesso) as a …

Into the origin of electrical conductivity for the metal–semiconductor junction at the atomic level

Arkadiusz Janas, Witold Piskorz, Aleksandr Kryshtal, Grzegorz Cempura et autres

The metal–semiconductor (M-S) junction based devices are commonly used in all sorts of electronic devices. Their electrical properties are defined by the metallic phase properties with a respect to the semiconductor used. Here we make an in-depth survey on the origin of …

Automatic microscopic image analysis by moving window local Fourier Transform and Machine Learning

Benedykt R. Jany, Arkadiusz Janas, F. Krok

Analysis of microscope images is a tedious work which requires patience and time, usually done manually by the microscopist after data collection. The results obtained in such a way might be biased by the human who performed the analysis. Here we introduce …

Chemically driven growth of Au-rich nanostructures on AIII-BV semiconductor surfaces

Benedykt R. Jany, Arkadiusz Janas, Witold Piskorz, Konrad Szajna et autres

AIII-BV semiconductors have been considered for decades to be a promising material in overcoming the limitations of silicone semiconductor devices. One of the important aspects within AIII-BV semiconductor technology are gold-semiconductor interactions on the nanoscale, since Au is widely used to catalyze …
