MOXY researchers at Technart 2025
At TECHNART 2025 in Perugia, Italy, researchers from the MOXY project showcased a series of studies centered on the sustainable, non-invasive cleaning and conservation of fire-damaged and sensitive cultural heritage materials.
Tomas Markevicius introduced a transformative technique using atmospheric atomic oxygen (AO) generated in non-equilibrium helium plasma for cleaning soot-blackened gypsum plaster surfaces. His method eliminates soot through chemical conversion into CO and COâ‚‚ at mild temperatures without physical contact, water, abrasives, or solvents—preserving the fragile artwork while ensuring effective soot removal. This innovation represents a significant leap forward in the safe restoration of fire-damaged heritage.
Cecilia Campi, examined the degradation mechanisms of silk, a common material in heritage artifacts, with the aim of tailoring conservation methods to the specific aging behaviors of silk. Her work contributes to MOXY’s overarching mission by advancing material-specific conservation approaches.
Sofie Wikkelsø Jensen, revealed another critical discovery—AO plasma induces a reversible hydration state transition in gypsum plaster, a previously unknown phenomenon with implications for both conservation science and chemistry. This finding expands our understanding of plasma-material interactions and supports the development of safe, reversible conservation technologies.
Kirill Shumikhin compared AO plasma and laser treatment on oil paint binders, analyzing their chemical and physical impacts to determine the relative safety and effectiveness of each method. His study helps define best practices for using these non-contact technologies on classic painted surfaces.
Catarina Rocha Pires (University of Amsterdam) evaluated novel dry and non-contact techniques for cleaning surface dirt from solvent-sensitive and mechanically fragile paintings. Her research also involved developing standardized mock-ups using replicated fire-born soot, enabling reproducible testing environments. This methodological innovation plays a vital role in ensuring cleaning methods can be reliably compared across studies.
Nan Yang focused specifically on the reproducibility of fire-born soot creation for such mock-ups, contributing essential groundwork that supports all comparative cleaning studies within MOXY.
​Marta Cremonesi presented an innovative digital image analysis framework to evaluate surface cleaning results using ImageJ, enabling quantifiable, reproducible assessment of AO’s impact.​
​
Together, these contributions affirmed MOXY’s central mission: to bring advanced, evidence-based plasma science into real-world conservation practice. In doing so, MOXY is helping to safeguard the material legacies of the past against the increasingly complex risks of the future.

MOXY project and Vilnius Symposium in the IIC News in Conservation
We are super exited to share the News in Conservation February/March Issue!
The MOXY project experimental feather landed on the cover of the magazine, where you can find an extented Vilnius Symposium 2024 review by Tomas Markevicius, Nina Olsson and Klaas Jan van den Berg. The review condenses the key moments and thoughs shared at the Symposium, and emphasizes: the shift to greener conservation practices is not just necessary, it is the future of the field, ensuring that our cultural treasures will be preserved for generations to come.

MOXY project featured in Artnews.com
Artnews, one of the most trusted and influential source of art news and marked, has mentioned MOXY project in their article ‘One of the Most Impactful Art Losses Ever’: Insurers Start to Assess LA Wildfire Damage written by Francesca Aton and Karen K. Ho.
As the assesment of loses in devastating Los Angeles wildfire, earlier this year, is still in progress, art collectors and conservators are starting to dig for possible treatments for the precious art collections kept in Los Angeles homes. Article pays attention to 'the appropriate and reputable resources, as well as professional organizations' which could help in saving damaged artworks. In this case, MOXY project is mentioned as an example of specific fire damage treatment.
