Chitosan Derivatives as Bio-based Materials for Paper Heritage Conservation

Nanoparticles Based on Chitosan Derivatives

Bio-Based Coatings for Paper Applications

The barrier resistance and wettability of papers are commonly controlled by the application of petroleum-based derivatives such as polyethylene, waxes and/or fluorderivatives as coating. While surface hydrophobicity is improved by employing these polymers, they have become disfavored due to limitations in fossil-oil resources, poor recyclability, and environmental concerns on generated waste wi...

Current advancements in applications of chitosan based nano-metal oxides as food preservative materials

Objective(s): A remarkable growing effort has been conducted by several researchers to fabricate food packaging materials which are able to protect foodstuffs and enhance their shelf-life from food-borne pathogens and fungal attack which causes great damage to the food industries. Recent studies has focused on the potential applications of nano-metal oxides in food packaging area. Method...

A Cultural Heritage Repository as Source for Learning Materials

We discuss a system for the digital capture of museum artefacts which are accumulated into a multimedia repository comprising 3D models, images, video and sound clips as well as textual descriptions. A comprehensive set of metadata is recorded and stored alongside these various media with the aim of reusing and re-purposing them for multiple applications. We investigate issues relating to both ...

A Comparison between β-Cyclodextrin and Chitosan as Soft Organic Materials for Surface Modification of MWCNTs

In this paper, synthesized (raw) multi-walled carbon nanotube (rMWCNTs) surfaces were modified with chitosan and β-cyclodextrin using Chen’s soft cutting technique. Raw and surface modified multi-walled carbon nanotubes were observed by transmission electron microscope (TEM). The results showed that chitosan and β-cyclodextrin could attach to the outer surface of nanotubes, wrapping the nanotub...
