Identification of Excavated Archaeological Textile Fibers and Analysis of Their Degraded States by Synchrotron Radiation FT-IR Microspectroscopy

A novel green chemistry gelation method for polyvinyl pyrrolidone (PVP) and dimethylpolysiloxane (silicone): microwave-induced in-liquid-plasma

“…), which is attributed to the amide II (N–H bending, and C–N stretching). 25 The peak at 1520 cm −1 derived from this new amido is attributed to the N , N ′-methylenebisamine cross-linker. However, as this peak is not seen in the PVP gel by the MILP method suggests that PVP undergoes decomposition by the MILP and the structure R–CO–NH–R is not generated.…”

The Study on Excavated Bast Fibers Using Synchrotron Polarized FT-IR Micro-Spectroscopy

“…The molecules of bast fibers consist of cellulose and hemicellulose, along with additional components such as lignin, waxes and residual proteins [2]. The authors have been investigated the identification of excavated textile fibers mainly using the synchrotron infrared spectroscopy (SR-FTIR), comparing with the data of modern reference fibers [3,4]. To further investigate the characteristic of bast fibers (hemp and ramie), their fiber morphology was observed using Scanning electron microscope (SEM), because their IR spectra were similar each other, and hence it requires the aid of SEM to identify the kind of excavated bast fibers [5].…”
