Solubility temperature and crystallization
WebLAM solubility as a function of temperature and solvent composition was obtained from literature, along with thermal property data for melting temperature and enthalpy of fusion. 16 This compound's enthalpy of fusion is on the higher end compared to common organic crystallization solutes, 10 presumably because LAM is decomposing near the ... Web2 days ago · The crystallization of drugs confined in the pores of AAO and their T g s show evident pore-size dependence. The temperature dependence of α-relaxation exhibits the significant change upon cooling, which is mainly attributed to the vitrification of molecules at the interface and the local density heterogeneity under the isochoric confinement.
