Epoxy resins are widely used polymeric materials owing to their excellent mechanical strength, chemical resistance, and adhesion properties. However, their relatively high flammability restricts their use in areas where improved fire safety is required. Therefore, modifying epoxy systems with effective flame-retardant additives is an important area of research. Among the various...

In spectrophotometric analysis, univariate calibration is often based on the intuitive assumption that the maximum of an absorption band provides the best analytical signal. This practice is closely connected to the Beer–Lambert relation, which suggests a linear dependence of absorbance on concentration and makes the most intense spectral position appear especially attractive because of its...
