WebThe process did not change the physicochemical properties and crystallinity of APZ. The fluorophore illuminated APZ crystals but was quenched upon dissolution of APZ-HCs in aqueous media, enabling monitoring intact APZ-HCs in real-time. ... The residual percentage of fluorescence intensity in rats treated by APZ-HCs was recorded with time ... WebCrystallinity index is the ratio of the crystalline peaks to the crystalline+amorphous peaks. Amorphous peaks are the noise in XRD data, while, from crystalline+amorphous, we mean the whole XRD...
How do I calculate crystallinity using a DSC curve?
WebAug 1, 2024 · The percent crystallinity, χ c, was determined using Equation (1): (1) χ c = Δ H m − Δ H c c Δ H 100 (ϕ P L A 100) × 100 where Δ H m is the enthalpy of melting, Δ H c c is the enthalpy of cold crystallization, Δ H 100 is the theoretical enthalpy of melting for a 100% crystalline polymer, which is 93 J g −1 for PLA [41], and ϕ PLA ...
