Characterising terpenic plant resins, wood tars and pitches in heritage science: analytical methods and applications Jeannette Jacqueline Łucejko, Irene Bertelli, Renata Costa, Bettina Ebert, Andreu Falcó, et al. Npj Heritage Science, 2026 This review examines natural plant resins, wood tars and pitches in heritage science, focusing on their historical uses, chemical composition and analytical characterisation. Particular attention is given to diterpenoid and triterpenoid resins and to chemical transformations induced by ageing, degradation and thermal processing. The identification of diagnostic molecular markers supports the determination of botanical origins and technological practices, while an overview of complementary analytical methods highlights current challenges and perspectives.
Adornments in Funeral Contexts: Analysis of a Necklace from the Bronze Age Cemetery at Cândești, Romania Monica Mărgărit, Anca-Diana Popescu, Mădălina Stănescu, Rodica-Mariana Ion, Sofia Slămnoiu-Teodorescu, et al. Heritage, 2026 The Cândești necropolis is currently the largest excavated Bronze Age necropolis in Romania, with approximately 800 graves. Notably, one grave from an earlier phase of the Monteoru culture (c. 2200–1850 BC) contained a remarkable necklace composed of 22 perforated gastropod shells and a metal pendant. Our investigation adopted an integrated approach, including taxonomic identification, taphonomic, technological and functional analyses, experimental studies, and physico-chemical investigations (Fourier Transform Infrared Spectroscopy and Raman spectroscopy) of the pigment traces present on the shells’s surface. For the metal pendant, X-Ray Fluorescence analysis was conducted to ascertain its elemental composition. The combined analysis yielded unexpected insights: the shells, belonging to the genus Conus, originated from the Mediterranean region. The perforations were not the result of anthropic intervention; rather, they were the result of natural processes, indicating that the shells were collected from thanatocoenoses. The shells were assembled into the necklace using a thread colored with a red pigment. The perforations show signs of prolonged use, suggesting that the necklace was not only a funerary offering. In conclusion, our study indicated that these exotic shells were collected post-mortem already perforated through a rubbing process in the seashore sediments, transported to the site from a distance, and prior to the death of the owner, had been previously worn as personal adornment before being deposited as grave goods.
Prediction of Thermal Degradation Parameters for Flame-Retardant Polypropylene-Reogard 2000 Composites Elena‐Janina Vîlcea, Maria‐Cristina Toader, Ovidiu‐Dorin Alupei‐Cojocariu, Rodica‐Mariana Ion, Manuela‐Roxana Dijmărescu Macromolecular Symposia, 2026 This paper examines the nature of the relationship between experimental thermal degradation data and numerical modeling data for flame‐retardant polypropylene composites containing Reogard 2000. Degradation temperature onset, maximum degradation temperature, residual mass, and enthalpy variation for different additive concentrations (5%–25%) were analysed by means of thermogravimetric (TG) and differential scanning calorimetry (DSC), with the resulting data sets being used to develop regression functions (linear and quadratic) and neural network models to predict the thermal behavior of the composites. Results show that the quadratic regression indicated excellent correlation levels ( R 2 > 0.95), while feed‐forward neural network resulted in R 2 > 0.9 for most of the parameters. The results show a high degree of fidelity and reliability of the proposed methodology of integrating experimental data with numerical modeling for the purposes of predicting thermal stability and supporting the viability of data driven optimizations for flame‐retardant polypropylene formulations.
Comprehensive Analysis of Gypsum Mortar with Glass Waste Aggregates as a Substitute for Sand Mohamed Amine Ouared, Abdelkader Bougara, Ismail Yurtdas, Rodica-Mariana Ion, Said Beldjilali, et al. Processes, 2026 Gypsum has been used as a building material for a long time due to its environmental friendliness, exceptional fire performance, and ease of use. However, it is also known to have poor moisture resistance and lower mechanical performance. Construction and demolition wastes, which can cause many environmental issues if not properly managed, are increasingly recycled as reinforcement materials in gypsum mortar. This study aims to assess the effect of incorporating fine glass waste aggregates into gypsum mortars on their physical, mechanical, and adhesive properties. The effect of replacing sand from 0% to 100% by glass waste in gypsum mortar was investigated using various tests and analyses including scanning electron microscopy (SEM), X-ray diffraction (XRD), thermal analysis (DTA and TGA), setting time, flexural and compressive strengths, adhesive, surface hardness, water absorption, thermal conductivity, and ultrasonic pulse velocity. The results obtained emphasize that glass waste can substitute sand in gypsum mortar, even when used at high replacement levels. Replacing all the sand in mortar with glass waste results in a 11% increase in porosity, a 9% decrease in density, and a 53% decrease in thermal conductivity, while still maintaining acceptable mechanical performances. The adhesive strength shows a great dependence on the nature of the substrate.
Three-Dimensional Digital Reconstruction and Archaeometric Approaches for Hydroxyapatite-Based Restoration of Sacidava Roman Fortress Rodica-Mariana Ion, Emanuel-Valentin Buică, Andrei Militaru, Sorin Marcel Colesniuc Coatings, 2025 This study presents an integrated digital and archaeometric investigation of the Roman fortress of Sacidava, located in Dobrogea, Romania. Combining 3D digital reconstruction and advanced material analysis, the research explores both the original architecture and the preserved state of the site. Using Autodesk Fusion 360, a complete 3D model was developed, digitally restoring the fortress as it likely appeared in the 4th century AD and enabling the generation of precise plans, sections, and photogrammetric elevations. Mortar samples from the eight towers of the Sacidava fortress were examined through scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), atomic force microscopy (AFM), and confocal laser scanning microscopy (CLSM), revealing phyllosilicate-rich matrices, carbonated lime residues, and heterogeneous microstructures. The most severe degradation was found in the towers facing the Danube (E2, F, G), which was strongly influenced by humidity and salt crystallization, while the southern towers (A–C) retained more stable textures. Hydroxyapatite (HAp) treatments visibly improved the surface condition by reducing roughness and sealing active pores. For the first time, chromatic parameters were correlated with environmental factors, such as pH, moisture, and salt content. ImageJ-based pseudo-computed tomography (pseudo-CT), principal component analysis (PCA), and dendrogram analyses confirmed a clear pattern of deterioration near the ancient port area, where increased acidity and moisture coincided with darker surface coloration and deeper microstructural alteration.
Waste Brick as Partial Replacement of Gypsum in Mortars: Mechanical Performance and Environmental Benefits for Sustainable Construction Said Beldjilali, Antonella Sarcinella, Mohamed Amine Ouared, Abdelkader Bougara, Khalil Naciri, et al. Sustainability Switzerland, 2025 Replacing virgin raw materials with recycled waste in construction products is a key strategy for advancing sustainable development. This study explores the partial substitution of commercial gypsum with powdered waste brick (WB) in gypsum mortars, assessing its impact on mechanical performance, water absorption, and environmental footprint. Mortars were prepared with 0%, 5%, 10%, 20%, and 30% WB by weight. Results indicate that a 20% replacement level enhances flexural strength by 56% and compressive strength by 33% at 28 days, compared to the reference mix. SEM and XRD analyses revealed no formation of new crystalline phases, suggesting that the performance improvement is primarily due to physical interactions and microstructural effects. However, at 30% WB, a significant reduction in adhesion strength was observed, falling below the typical threshold for gypsum-based coatings, which may constrain practical application at higher replacement levels. Environmental assessment showed that both CO2 emissions and energy consumption decreased by up to 20% with a 30% substitution. A 20% WB content is therefore proposed as the optimal compromise between mechanical performance and environmental benefit. This approach supports circular economy principles by promoting the reuse of ceramic construction waste in the development of new sustainable materials.
Sustainable and Functional Polymeric Coating for Wood Preservation Ramona Marina Grigorescu, Rodica-Mariana Ion, Lorena Iancu, Sofia Slamnoiu-Teodorescu, Anca Irina Gheboianu, et al. Coatings, 2025 The development of sustainable and functional nanocomposites has attracted considerable attention in recent years due to their broad spectrum of potential applications, including wood preservation. Also, a global goal is to reuse the large volumes of waste for environmental issues. In this context, the aim of the study was to obtain soda lignin particles, to graft ZnO nanoparticles onto their surface and to apply these hybrids, embedded into a biodegradable polymer matrix, as protection/preservation coating for oak wood. The organic–inorganic hybrids were characterized in terms of compositional, structural, thermal, and morphological properties that confirm the efficacy of soda lignin extraction and ZnO grafting by physical adsorption onto the decorating support and by weak interactions and coordination bonding between the components. The developed solution based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and lignin-ZnO was applied to oak wood specimens by brushing, and the improvement in hydrophobicity (evaluated by water absorption that decreased by 48.8% more than wood, humidity tests where the treated sample had a humidity of 4.734% in comparison with 34.911% for control, and contact angle of 97.8° vs. 80.5° for untreated wood) and UV and fungal attack protection, while maintaining the color and aspect of specimens, was sustained. L.ZnO are well dispersed into the polymer matrix, ensuring a smooth and less porous wood surface. According to the results, the obtained wood coating using both a biodegradable polymeric matrix and a waste-based preservative can be applied for protection against weathering degradation factors, with limited water uptake and swelling of the wood, UV shielding, reduced wood discoloration and photo-degradation, effective protection against fungi, and esthetic quality.
Architectural Heritage Conservation and Green Restoration with Hydroxyapatite Sustainable Eco-Materials Alina Moșiu, Rodica-Mariana Ion, Iasmina Onescu, Meda Laura Moșiu, Ovidiu-Constantin Bunget, et al. Sustainability Switzerland, 2025 Sustainable architectural heritage conservation focuses on preserving historical buildings while promoting environmental sustainability. It involves using eco-friendly materials and methods to ensure that the cultural value of these structures is maintained while minimizing their ecological impact. In this paper, the use of the hydroxyapatite (HAp) in various combinations on masonry samples is presented, with the aim of identifying the ideal solution to be applied to an entire historical building in Banloc monument. The new solution has various advantages: compatibility with historical lime mortars (chemical and physical), increased durability under aggressive environmental conditions, non-invasive and reversible, aligning with conservation ethics, bioinspired material that avoids harmful synthetic additives, preservation of esthetics—minimal visual change to treated surfaces, and nanostructural (determined via SEM and AFM) reinforcement to improve cohesion without altering the porosity. An innovative approach involving hydroxiapatite addition to commercial mortars is developed and presented within this paper. Physico-chemical, mechanical studies, and architectural and economic trends will be addressed in this paper. Some specific tests (reduced water absorption, increased adhesion, high mechanical strength, unchanged chromatic aspect, high contact angle, not dangerous freeze–thaw test, reduced carbonation test), will be presented to evidence the capability of hydroxyapatite to be incorporated into green renovation efforts, strengthen the consolidation layer, and focus on its potential uses as an eco-material in building construction and renovation. The methodology employed in evaluating the comparative performance of hydroxyapatite (HAp)-modified mortar versus standard Baumit MPI25 mortar includes a standard error (SE) analysis computed column-wise across performance indicators. To further substantiate the claim of “optimal performance” at 20% HAp addition, independent samples t-tests were performed. The results of the independent samples t-tests were applied to three performance and cost indicators: Application Cost, Annualized Cost, and Efficiency-Cost-Performance (ECP) Index. This validates the claim that HAp-modified mortar offers superior overall performance when considering efficiency, cost, and durability combined.
The Effect of Bio-Based Polyamide 10.10 and Treated Fly Ash on Glass-Fiber-Reinforced Polyamide 6 Properties George-Mihail Teodorescu, Zina Vuluga, Toma Fistoș, Sofia Slămnoiu-Teodorescu, Jenica Paceagiu, et al. Polymers, 2025 Increased concern for human health and the environment has pushed various industries to adopt new approaches towards satisfying modern regulations. Strategies to achieve these approaches include utilizing lightweight materials, repurposing waste materials, and substituting synthetic polymers with bio-based counterparts. This study investigates the effects of treated fly ash (C) and bio-based polyamide 10.10 (PA10) on the thermal, morphological, and mechanical properties of glass fiber (GF)-reinforced polyamide 6 (PA6). Our main objective was to develop a composite that would allow for the partial replacement of glass fiber in reinforced polyamide 6 composites (PA6-30G) while maintaining a favorable balance of mechanical properties. Composites processed via melt processing demonstrated enhanced mechanical properties compared to PA6-30G. Notably, significant improvements were observed in impact strength and tensile strain at break. The addition of PA10 resulted in increases of 18% in impact strength and 35% in tensile strain relative to PA6-30G. Complementary, structural and morphological analyses confirmed strong interfacial interactions within the composite matrix. These findings indicate that a PA6/PA10 hybrid composite may represent a viable alternative material for potential automotive applications.
