Polar benzotriazoles are corrosion inhibitors with widespread use; they are environmentally characterized as emerging pollutants in the water system, where they are present in low concentrations. Various extraction methods have been used for their separation from various matrices, ranging from class ...

Determination of cellulose degree of polymerization (DP) is one of the most commonly used methods in paper degradation studies, performed either by a standardized method using viscometry (as average degree of polymerization (DP$_v$)) or size-exclusion chromatography (SEC) (as weight average molecula ...

Hlapne organske spojine (HOS) so lahko naravnega ali antropogenega izvora in lahko vplivajo na zdravje ljudi, kakovost zraka in na materiale ter na predmete, ki se nahajajo v prostorih s povišano koncentracijo HOS. V svoji diplomski nalogi sem v izbranih prostorih fakultete meril celokupne koncentra ...

Wood is a natural polymeric material that is an important constituent of many heritage collections. Because of its susceptibility to biodegradation, it is often chemically treated with substances that can be harmful to human health. One of the most widely used wood preservatives was pentachloropheno ...

The acidity of historic paper, a property crucial for its preservation, is thought to mainly depend on the type of sizing. However, this research shows that during its degradation, paper acidity increases mainly due to the formation of non-volatile carboxylic acids, which accelerate acid-catalysed h ...

Benzotriazole and its derivatives (BTAs) are commonly present in wastewater due to their extensive use in industrial processes, yet their removal is still unexplored. Here, we test the removal of these pollutants using two functionalised biochars, synthesised from wild plum (WpOH) and apricot (AsPhA ...

Archival boxes are used as a preventive measure to control the microenvironment in museums and archives storages. However, their efficiency in protecting valuable artefacts from fluctuations in relative humidity (RH) is not yet fully understood. In this study, the environmental performance of differ ...

Historic objects made of cellulose acetate are potential sources of indoor pollution in heritage collections. 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 an ...

Ancient Egyptian mummification was a mortuary practice aimed at preserving the body and soul for the afterlife, achieved through a detailed ritual of embalming using oils, waxes, and balms. While most research on Egyptian mummified bodies has so far been conducted in European collections, our study ...
