As these objects degrade, volatile organic compounds, including acetic acid, are produced and emitted. High concentrations of acetic acid can increase the degradation rate of both organic and inorganic objects stored nearby. In this study, micro-invasive sampling and ion chromatography were used to quantify acetic acid emission rates from objects made of cellulose acetate, including 3D objects and photographic negatives. It was observed that some degrading objects emit acetic acid at high rates, even under standard environmental conditions (20 °C and 30% RH) that are prescribed for storage of objects made of cellulose acetate. The emission rate was found to be governed by the internal diffusion for thicker cellulose acetate objects and by the surface evaporation for thinner objects. In the diffusion-controlled mode of emission, the airflow did not accelerate acetic acid emissions. To compare the storage options for cellulose acetate objects, the emission rates of acetic acid were used as the inputs for models predicting the equilibrium acetic acid concentrations in various enclosures (archival box, surface-coated archival box, metal can, and display case). It was observed that surface-coated boxes contained higher concentrations of acetic acid than other enclosures, mainly due to their low air exchange rates and deposition velocities.","PeriodicalId":520430,"journal":{"name":"NPJ heritage science","volume":"13 1","pages":"22"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11867026/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genomic and proteomic studies have particularly contributed to prior visual and microscopic methods to broaden complex themes such as society, identity, technology, economy and trade. We have termed this new interdisciplinary field \"clothomics\", as it applies diverse omics methodologies, such as genomics and proteomics, to expand the horizons of cloth research. This paper aims at providing users with a set of practical step-by-step guides for the most widely applied omics analyses of cloth, proteomics and genomics, in animal-based materials. The paper reviews current applications, provides recommendations for selecting the right analytical strategy, focusing on practical considerations like how to sample, how to choose between proteomic and genomic methodological approaches, and where we see the current limitations. We are optimistic with the field of clothomics as we see it receives more attention scientifically and from the funding bodies. Although it faces several technical challenges, we also experience attempts to overcome these by recovering and detecting more biomolecules and becoming a more inclusive field through data sharing and participatory science. With a close collaboration between scholars of different disciplines, clothomics will provide a better understanding of human-animal interactions and the use of animal products beyond subsistence.","PeriodicalId":520430,"journal":{"name":"NPJ heritage science","volume":"13 1","pages":"80"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11913735/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
