Due to the presence of organic functional groups, these materials inevitably exhibit characteristic vibrational or rotational absorption peaks in the infrared spectrum, which is contrary to the ...

Using Fourier-transform infrared spectroscopy (FTIR), the study synthesised a modified complex called MAC and investigated crosslinking interactions between polymers, monomers, and crosslinking agents ...

Researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared spectra. NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to ...

The chemical structure of these new lignin esters was determined using Solid-state 13 C CP-MAS NMR and FT-IR analysis. 31 P NMR analysis ... The KL was purified as follows to remove residues of free ...

These acids are abietic acid, dehydroabietic ... For conversion of rosin into rosin maleic anhydride adduct, conditions for synthesis, a scheme for chemical reactions, confirmation of chemical ...

Maleic acid (MA) has emerged as a promising candidate for acid treatment of cellulose, primarily due to its eco-friendly nature and mild reaction conditions. In our previous work, it proved that ...

The terahertz and Raman spectra of the lattice vibrations of crystalline maleic acid and fumaric acid have been measured and then successfully modeled using solid-state density functional theory to ...
