Crystallization kinetics of poly(lactic acid)-talc composites [PDF]
, 2011 The crystallization kinetics of Poly(lactic acid) / talc composites were determined over a range of 0 wt.% to 15 wt.% of talc. Talc was found to change the crystallization kinetics.

Temperatures in ambient mantle and plumes: Constraints from basalts, picrites, and komatiites [PDF]
, 2006 Several methods have been developed to assess the thermal state of the mantle below oceanic ridges, islands, and plateaus, on the basis of the petrology and geochemistry of erupted lavas. One leads to the conclusion that mantle potential temperature (i.e.

Multiple Melting Temperatures in Glass-Forming Melts
, 2022 All materials are vitrified by fast quenching even monoatomic substances. Second melting temperatures accompanied by weak exothermic or endothermic heat are often observed at Tn+ after remelting them above the equilibrium thermodynamic melting transition

Equilibrium melting temperature and crystallization kinetics of α- and β′-PBN crystal forms [PDF]
Polymer Journal, 2011 The melting behavior and the crystallization kinetics of poly(butylene/diethylene naphthalate) and poly(butylene/thiodiethylene naphthalate) random copolymers were investigated by means of DSC. By the Hoffman–Weeks’ method, the Tm° of α and β′-PBN phases were derived: the Tm° value of β′-form was higher, as expected, taking into account that it is ...

Reduction of melting temperature and enthalpy of drug crystals: Theoretical aspects
European Journal of Pharmaceutical Sciences, 2013 This review deals with the mathematical models describing the reduction of melting temperature and enthalpy of solids in the nano-size range. In particular, the attention focuses on the thermodynamic based models that are theoretically solid and can be suitably used in the case of organic drugs.

Highly crystallized poly (lactic acid) under high pressure
AIP Advances, 2012 Biodegradable poly (lactic acid) (PLA) usually has a crystallinity less than 10% due to its poor crystallization ability. In this work, we found high pressure could significantly facilitate formation of crystallites of PLA, resulting in a crystallinity ...
