![]() With these techniques we can not only communicate, but we can also map the world around us. Assistant professor Hamdi Joudeh of the department of Electrical Engineering wants to lay the foundation for a completely new feature of our future mobile networks such as 6G. We owe these possibilities to fast mobile networks such as today's 5G. Watching a movie or making a video call on the go doesn't feel that special. "Previous research I did was about the chemical and physical degradation of completely different materials, for instance, concrete, but the fact that I can now apply this to cultural heritage is fantastic."īosco will use the ERC Starting Grant to hire two doctoral students and a postdoc. She is pleased with the new direction she has taken. The techniques Bosco uses are now being applied to paintings for the first time. Moreover, there is a general lack of information, because directly testing historical works is not possible. Much less is known about the mechanical behaviour and physical degradation of paintings. This happened, for example, in works by Vincent van Gogh. Previous research focused mainly on the chemistry of substances, for example, how pigments can change colour. She says the model can ultimately help determine the best conservation strategy.īosco investigates different types of canvas and pigments, such as the so-called lead white, which was used as a substrate in almost all classical paintings, and various organic dyes derived from soil. We use that to support predictions," Bosco said. "With well-known works like the Night Watch, there has been a lot of research on degradation and deformation. The results are then compared with real paintings. The data on the behaviour of the samples go into a computer model that predicts the behaviour on a larger scale. She also looks at how moisture and temperature affect a painting. "This gives you a lot of information about how the paint behaves and how cracks start in it," she says. To do this, she takes barely visible samples (micrometers in size) from original artworks and subjects them to mechanical tests. Chemical and physical interactions between these layers cause complex degradation mechanisms, something conservators are trying to prevent.īosco is developing a method to make predictions about the damage a painting may suffer in the future, departing from the behavior of canvas and paint at the microscale. These are painted on yet another material, the canvas. ![]() For example, there are often multiple layers of oil paint made up of different pigments. It may seem simple, but in terms of materials, a painting is complex, Bosco says. She aims to use microscopic samples to predict how a painting behaves as a whole. Associate Professor Emanuela Bosco (department of Built Environment) investigates the complex physics behind damage, cracks and distortions in historical paintings.
