Unilateral NMR: a Noninvasive Tool for Monitoring In Situ the Effectiveness of Intervention to Reduce the Capillary Raise of Water in an Ancient Deteriorated Wall Painting

International Journal of Spectroscopy, Volume 2012, Issue 1, 2012., 2012
Portable unilateral NMR was used to quantitatively map in a fully noninvasive way the moisture distribution in an ancient deteriorated wall painting before and after an intervention to reduce the capillary raise of water through the wall. Maps obtained at a depth of 0.5 cm clearly showed the path of the capillary raise and indicated that, after the ...

Effects of Different Artificial Agings on Structure and Properties of Whatman Paper Samples

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
With the aim at controlling cellulose degradation phenomena, the natural aging of Whatman paper samples was simulated through different artificial aging processes: thermal oxidation in air at constant temperature, photo‐oxidation under Xenon arc lamp, accelerating ageing in climatic chamber, and chemical oxidation with sodium methaperiodate.

Can Coastal Rowing Be Made Safer Through Auxetics‐Inspired Personal Protective Equipment?

physica status solidi (b), Volume 263, Issue 5, May 2026.
A survey of beach sprint coastal rowers examined perceived injury risk, attitudes towards personal protective equipment (PPE) and barriers to its use. The findings were used to guide the design of auxetic‐based PPE for this sport that is highly conforming, breathable and visually appealing. We report the results of a survey aimed at assessing how beach

Investigations into the characterization, degradation, and applications of biodegradable polymers by mass spectrometry

Mass Spectrometry Reviews, Volume 44, Issue 6, Page 947-988, November/December 2025.
Abstract Biodegradable polymers have been getting more and more attention because of their contribution to the plastic pollution environmental issues and to move towards a circular economy. Nevertheless, biodegradable materials still exhibit various disadvantages restraining a widespread use in the market.

A critical study of sustainable biocomposites developed from rheologically distinct poly(butylene adipate‐co‐terephthalate) (PBAT) reinforced with biocarbon from coconut (Cocos nucifera) for rigid applications

The Canadian Journal of Chemical Engineering, Volume 103, Issue 9, Page 4301-4313, September 2025.
This work highlights the development of a sustainable composite with improved dimensional and thermal stability as well as mechanical performance, for rigid application. To promote sustainability and a circular economy, we have reduced PBAT percentage content by half and incorporated waste coconut shell up to 50 wt.%.

Polyamide recycling by selective dissolution approach: Life Cycle Assessment study and environmental impacts comparison with different recycling technologies

Polymer Engineering &Science, Volume 65, Issue 2, Page 765-782, February 2025.
The study evaluates the industrial feasibility of the selective dissolution recycling of polyamide 6 (PA6) waste, comparing it with the current industrial recycling methods (mechanical and chemical), in terms of environmental impacts and applicability. Solvent‐based recycling appears promising, with a Global Warming Potential (GWP) between chemical and

Wood flour and hazelnut shells polylactide‐based biocomposites for packaging applications: Characterization, photo‐oxidation, and compost burial degradation

Polymer Composites, Volume 45, Issue 11, Page 9802-9818, 10 August 2024.
A biocomposites studying from the cradle to the grave. Abstract In this work, polylactide (PLA) was loaded with wood flour (WF) or hazelnut shells (HSs) (10% and 20% of fillers). The matrix and biocomposites were fully characterized from a mechanical and rheological point of view to test their processability and mechanical performance.
