Chapter 4</br>Will our children have the chance to do research on today’s digital books?

2016

In this chapter, I will first position my considerations about the sustainability of ebooks for future research in the context of book history; moreover, I will introduce basic concepts of (migration and emulation) as well as challenges to the long-term preservation of digital data in greater generality. After that and taking current research on past (printed) books as an analogy, I shall try to outline which kinds of (digital) material will be indispensable in the future to do research on today's digital book production: published digital materials and unique (digital) artefacts. Finally, I shall present the results of my exemplary studies to find out which precautions for the future avail…

Halloysite Nanotubes Loaded with Calcium Hydroxide: Alkaline Fillers for the Deacidification of Waterlogged Archeological Woods

2018

A novel green protocol for the deacidifying consolidation of waterlogged archaeological woods through aqueous dispersions of polyethylene glycol (PEG) 1500 and halloysite nanotubes containing calcium hydroxide has been designed. First, we prepared functionalized halloysite nanotubes filled with Ca(OH)2 in their lumen. The controlled and sustained release of Ca(OH)2 from the halloysite lumen extended its neutralization action over time, allowing the development of a long-term deacidification of the wood samples. A preliminary thermomechanical characterization of clay/polymer nanocomposites allows us to determine the experimental conditions to maximize the consolidation efficiency of the wood…
