AI Article Synopsis
- * Utilizes solid-state nuclear magnetic resonance (NMR) spectroscopy to analyze different tannin families in historical leather items, while also exploring leather deterioration, specifically collagen gelatinization.
- * Compares NMR findings with Fourier transform infrared (FTIR) spectroscopy and micro-differential scanning calorimetry (micro-DSC) to highlight the strengths and weaknesses of these methods in analyzing historical leathers, along with building a database of commercial tannin spectra.
Article Abstract
Ancient vegetable tanned leathers and parchments are very complex materials in which both different manufacturing and deterioration processes make their study and chemical characterisation difficult. In this research, solid-state nuclear magnetic resonance (NMR) spectroscopy was applied to identify different tannin families (condensed and hydrolysable) in historical leather objects such as bookbindings, wall upholsters, footwear and accessories, and military apparel. Furthermore, leather deterioration with special focus on collagen gelatinisation was investigated. A comparison with Fourier transform infrared (FTIR) spectroscopy and micro-differential scanning calorimetry (micro-DSC) was also performed to support the C CP-MAS NMR findings and to point out the advantages and limitations of solid-state NMR in analysing historical and archaeological leathers. A wide database of NMR and FTIR spectra of commercial tannins compounds was also collected in order to characterise historical and archaeological leathers.

Constructing highly conjugated three-dimensional covalent organic frameworks (3D COFs), particularly those with luminescent features, remains a significant challenge. In this work, we successfully synthesized a 3D COF, named 3D-Py-SP-COF, using a rigid and orthogonal spirobifluorene building block for the spatial 3D structure construction and planar pyrene as luminescent units. The incorporation of the pyrene and the unique rigid 3D network structure endow 3D-Py-SP-COF with fluorescent properties.

NMR spectroscopy presents boundless opportunities for understanding the structure, dynamics, and function for a broad range of scientific applications. Solid-state NMR (SSNMR), in particular, provides novel insights into biological and material systems that are not amenable to other approaches. However, a major bottleneck is the extent of user training and the difficulty of obtaining reproducible, high-quality experimental results, especially for the sophisticated multidimensional pulse sequences that are essential to provide site-resolved measurements in large biomolecules.

This study explores the formulation and characterization of poly(vinyl alcohol) (PVA)-based composite hydrogels synthesized through solid-state crosslinking. Comprehensive assessments were conducted on their physicochemical properties, leachables, and immunogenicity. Swelling experiments demonstrated that the incorporation of poly(vinylpyrrolidone) (PVP) enhanced water retention, while chitosan had a minimal effect on swelling behavior.

High Resolution-Magic Angle Spinning (HR-MAS) solid-state NMR spectroscopy is finding increasing application in the analysis of solid foods, bypassing the need for complicated solvent extraction procedures. In the present protocol, we report a simple analytical approach based on HR-MAS NMR spectroscopy for the phenolic profiling of olive fruits, flesh, or skin. This approach allows the facile characterization of phenolic compounds in olive fruits cultivated for extra-virgin olive oil production as a function of maturation and variety, in addition to processing technology for table olives.

The energy density of layered oxides of Li-ion batteries can be enhanced by inducing oxygen redox through replacing transition metal (TM) ions with Li ions in the TM layer. Undesirably, the cathodes always suffer from unfavorable structural degradation, which is closely associated with irreversible TM migration and slab gliding, resulting in continuous capacity and voltage decay. Herein, attention is paid to the Li ions in the TM layer (Li) and find their extra effects beyond inducing oxygen redox, which has been rarely mentioned.
