“…Figure 6a shows the spectra of the palm leaf manuscripts obtained by ATR-FTIR b tween 4000 cm −1 and 500 cm −1 . Similar to wood, palm leaves consist mainly of cellulo hemicellulose, and lignin, along with other substances such as fats and proteins [26,2 The bands at 2927 cm −1 and 2855 cm −1 correspond to asymmetric and symmetric stretchi vibrations of CH2 groups, respectively, and are attributable to the methylene groups fats and waxes [28,29]. The peak absorption intensity of BP-1 and BP-3 was lower th that of BP-R due to the effect of degradation.…”

Palm leaf manuscripts were a prevalent literary medium from South Asia and Southeast Asia prior to the widespread use of paper. This study focuses on the analysis of historical palm leaf manuscripts from South and Southeast Asia. Sample palm leaf manuscripts from Burma were used as a case study; simulated palm leaf manuscripts were also created as a reference for comparison. The anatomy, chemical composition, and mechanical properties of the manuscripts were analyzed to find various forms of deterioration, including damage, fractures, pollution, acidification, and microbial deterioration. Specifically, the S1–S3 layers of the cell walls exhibited complete cracking, and the S2 layer showed numerous circular or nearly circular cavities caused by microbial erosion, while the middle lamella remained intact. The severe degradation of polysaccharides and pectin, accompanied by an increase in the relative content of lignin, caused the historical manuscripts to become more brittle. Additionally, the tensile strengths of historical palm leaf manuscripts were markedly reduced; their longitudinal tensile strength was significantly greater than their transverse tensile strength. This study can contribute to a better understanding of the deterioration process of historical palm leaf manuscripts and provide valuable insights for their restoration and preservation.

“…The C = O group has an absorption band of approximately 1735 cm -1 , which stands for the ester-containing substances found in hemicellulose, pectin, and the cholesterol esters found in cell walls [19]. The amide I band is closely tied to the backbone conformation and is mostly involved with the C = O stretching vibration (70%-80%) [16]. In this work, a peak was observed in the Amide I region, which appeared between the range of 1616-1644 cm -1 as shown in Fig.…”

The current study used the Fourier Transform Infrared (FTIR) spectroscopy to determine the corresponding changes caused by salt-induced biochemical changes at different NaCl concentrations (2.5 as control level, 5, 10, and 20 ds.m− 1). FTIR also determines the potential role of selenium nanoparticles (Se NPs) at two concentrations (80 and 160 ppm) in alleviating salinity stress on date palm (Phoenix dactylifera L.) trees. Notably, the study found the appearance of a new peak at 2850 cm− 1 in the lipid region (2800–3000 cm− 1) when date palm trees were exposed to salinity and tested at all levels. This peak was not seen in the control treatment or when salinity was combined with foliar spraying of Se NPs at the two tested concentrations (80 and 160 ppm). Furthermore, a clear and distinct peak at 1735 cm− 1 was only seen in plants exposed to salinity at 10 or 20 ds.m− 1. This peak was attributed to membrane lipid compounds that contain carbonyl-ester groups. In addition, the findings demonstrate that the treatments from various studies affected the secondary structure of proteins (1500–1800 cm− 1) and carbohydrates (1200–1500 cm− 1), and this was evident by the appearance and disappearance of some characteristic peaks in these regions.

“…Depending on the conditions (e.g., saturation state, temperature, pressure and water activity), this group of evaporite minerals can precipitate to form anhydrite (CaSO 4 ), bassanite (CaSO 4 ·1/2H 2 O) or gypsum (CaSO 4 ·2H 2 O) (Van Driessche et al, 2017). Gypsum biomineralisation is the most commonly reported and is usually associated with plants growing on gypsum soils (Kayabaş & Yi̇ldi̇ri̇m, 2021; Moore et al, 2014; Muller et al, 2017; Palacio et al, 2014). However, gypsum biomineralisation has also been observed in Acacia spp.…”

Calcium biomineralisation is widely documented in plants. However, crystallisation of Ca‐sulphate‐containing minerals is closely related to water content, and sample processing, such as drying, alters the water balance of plant tissues. We hypothesised that common sample processing practices may favour the formation of crystals, leading to spurious crystallisation not observed in unaltered plant tissues. We selected three species (Ononis tridentata, Helianthemum squamatum and Gypsophila struthium) with reported gypsum biomineralisation. We used x‐ray diffractometry on fresh intact or sliced leaves, and on the same leaves processed by subsequent drying, to address whether sample processing alters crystal formation. Ca‐sulphate crystals were detected in dry samples of all species but not in fresh intact samples. Ca‐sulphate crystallisation occurred in some cut fresh samples, although the accumulation greatly increased after drying. In addition, G. struthium exhibited Ca‐oxalate crystals in both fresh and dry treatments, with a tendency for greater accumulation in dry treatments. Our results demonstrate that the Ca‐sulphate crystals observed by x‐ray diffractometry in these species are artefacts caused by common sample processing practices, such as excessive drying and slicing samples. We encourage future studies on the biomineral potential of plants to avoid the use of procedures that alter the water balance of tissues.
