Periodic Reporting for period 2 - MOXY (GREEN ATMOSPHERIC PLASMA-GENERATED MONOATOMIC OXYGEN TECHNOLOGY FOR CONTACTLESS ATOMIC SCALE CLEANING OF WORKS OF ART/ MOXY)
Période du rapport: 2024-01-01 au 2024-12-31
The groundbreaking MOXY mission is a response to the urgent need to safeguard cultural heritage CH from the climate crisis, unsustainable living, and social unrest. Numerous CH materials cannot tolerate mechanical “wet” or “dry” cleaning methods and professionals in all areas of specialization increasingly encounter surfaces where soiling cannot be removed at all. MOXY spearheads the green transformation in CH conservation and empowers practitioners with a groundbreaking atomic oxygen (AO) technology to remove carbon-based contaminants in a contact-free and liquid-free action. Groundbreaking non-contact AO cleaning technology offers a new opportunity cleaning a broad range of CH materials, such as paper, textiles, painted surfaces, plaster, metals, plastics, from carbon-based contaminants.
The overall objectives can be summarized as following:
O1 Green AO technology elicitation study, based on interviews with the end-users
O2 Research and development of an atmospheric AO device prototype – proof of concept
O3 Investigating AO generation pathway and transport to the substrate
O4 Investigating AO interactions with carbon-based contaminants and art materials
O5 Testing and characterizing the AO effluent for conservation applications
O6 Developing an affordable high accuracy AO sensor technology to quantify AO flux parameters
O7 Technology road-mapping and investigating the environmental impact via LCA.
O8 Demonstration, Dissemination, and Public Outreach
Scientific and technological innovation by MOXY project contribute to the development an innovative and green non-contact cleaning methods, offering a groundbreaking technology, which does not raise health or environmental concerns, and can be upscaled. To ensure that AO technology is indeed green and sustainable, the MOXY project approach is based on full Life Cycle thinking to the conservation of CH and Safe & Sustainable by Design (SSBD) framework.

MOXY researchers beyond the management and coordination (WP8) have been working on the following work packages WP1-7:
WP1 Proof-of-concept AO system for contact-free cleaning of the works of art
WP2 AO green technology elicitation for CH conservation and road-mapping
WP3 Selection of art materials and samples for AO cleaning
WP4 Development, testing and evaluation of contact-free AO cleaning technology
WP5 Investigations & assessment of AO interactions with CH materials in cleaning treatments
WP6 Eco-design and sustainability assessment
WP7 Demonstration, dissemination, knowledge transfer and public outreach
The consortium continues the work in all WPs. Overall progress in WP1-8 in GP2 was well in according with the project proposal and time plan. The AO system has been investigated in terms of possible optimization of AO flux to the surface of the treated objects. Two methods of AO enhancement were tested: (i) pulsing the RF voltage (ii) variation of the RF voltage waveform by adding RF harmonics which are both related to activities of WP1. The proposed method of AO control is new and innovative as it provides a precise way to control the effect of treatment. The AO generation was successfully tailored. The generated effluent rich of atomic oxygen has been characterized by ps-/ns- TALIF spectroscopy with first results available now for all members of the consortium. The new movable platform has been constructed for UPiza and will be installed in their facilities in next GP. To evaluate the limitations of the AO technology and boundaries in the use for CH the involvement of end-users from the early stages of design (WP2) via the technology elicitation study and interviews is performed. An inventory survey of prospective CH materials and contaminants has been updated in GP2, new protocols for ageing and preparing mock-ups are now completed (WP3). The testing approach including the methods of analysis were developed and compared with other protocols available, AO testing for treatment of different objects is in progress (WP4), investigating physical and chemical changes from the cleaning process is in progress (WP5). The consortium continues the work on eco-design and study the life-cycle of AO technology based hot-spot analysis (WP6). All indicated results were disseminated and communicated to various users (WP7) with number of events organized under MOXY project coordination (WP7,8)

A multitude of CH materials cannot tolerate the available “wet” or “dry” cleaning methods, which often use materials with unsustainable health and environmental impacts. AO cleaning process is non-liquid, volatile, nonthermal, and does not require or produce materials that raise environmental concerns. The ambitious MOXY results present a breakthrough in green cleaning methods:
- Green non-contact cleaning material: new opportunities to treat materials, that cannot sustain “wet” and “dry” cleaning methods
- Safe for health and the environment: reduces the carbon footprint, waste, and reliance on chemicals.
- Non-contact and non-liquid solution for friable, unstable materials.
- Volatile, non-thermal: can access contaminants in porous substrates.
- Culturally accepted: oxygen as a natural element would be culturally acceptable for indigenous and world culture communities that do not consent to the use of man-made materials treating rock art and sacred objects.
- New material for first responder actions treating CH objects that suffered from fire-born soot
- New ways to remove completely biological contaminants
