“…This questionable assumption raises difficulties in establishing correct reaction models and determining related kinetic parameters. On the other hand, non-isothermal reaction kinetic analysis has also been developed to investigate the reaction processes [28,29]. In non-isothermal analysis, the reaction conditions and actual temperatures are recorded, and the obtained conversion data can be analyzed using different methods.…”

“…Cure Monitoring. The monitoring of cure process is important to control and design optimal properties for advanced materials.Various methods such as differential scanning calorimetry (DSC), 24b, FT-IR spectroscopy, UV-reflectance spectroscopy, ,10a solid-state NMR spectroscopy, and ESR spectroscopy 31 have been utilized to study cross-linking or cure system. Among them, recently, fluorescence spectroscopic techniques have gained an considerable interest as a significant tool for the cross-linking or cure monitoring. 24b,− Neckers and Strehmel et al used a strong medium-dependent fluorescence probe to monitor photoinduced radical and cationic cross-linking.…”

Bismaleimides and bisitaconimides bearing diphenylmethylamine, triphenylamine, or 2,5-diphenyl-1,3,4-oxadiazole chromophore (symbolized as A(=)−D (*) −A(=)), as well as their saturated model compounds were synthesized, and their steady-state and time-resolved fluorescence spectra were investigated. These A(=)−D(*)−A(=) monomers display strong intramolecular fluorescence quenching. Their fluorescence quantum yields and lifetimes are generally lower than those of their model compounds. It was found that the electron-poor CC bond of maleimide and itaconimide units (A(=)) plays a key role in the intramolecular quenching, which is correlated to the electron-accepting ability of A(=) and the geometry arrangement between A(=) and electron-donating chromophore (D(*)). The intramolecular quenching was attributed to an intramolecular charge transfer interaction, which was confirmed by intermolecular fluorescence quenching and time-resolved fluorescence studies. On the basis of the intramolecular quenching, a new fluorescence approach can be developed to monitor the process of the polymerization and curing of bismaleimides, which can directly reflect the CC bond consumption during polymerization and curing. The new fluorescence approach can be utilized not only by an intrinsic fluorescence technique but also by an extrinsic fluorescence technique.

Changes in melting points, enthalpy, and specific heat capacity of catfish visceral oil at each step of the purification process were studied. Melting points of -46.2 to 21.2°C for crude oil, -45.9 to 11.5°C for degummed oil, -44.3 to 11.4°C for neutralized oil, -47.1 to 9.9°C for bleached oil and -52.3 to 8.0°C for deodorized oil were observed. Enthalpy (kJ/kg) was 74.1 for crude oil, 74.7 for degummed oil, 75.1 for neutralized oil, 79.3 for bleached oil, and 84.3 for deodorized oil. The specific heat capacities at 20°C for crude, degummed, neutralized, bleached, and deodorized oils were 1.69, 1.96, 1.97, 1.91, and 1.83 kJ/kg°C, respectively.
