Application of Solution Calorimetry to Determining the Fusion Enthalpy of an Arylaliphatic Compound at 298.15 K: n-Octadecanophenone

Liquids, 2022
Evaluating the temperature dependence of the fusion enthalpy is no trivial task, as any compound melts at a unique temperature. At the same time, knowledge of the fusion enthalpies under some common conditions, particularly at the reference temperature ...

The Influence of the Processing Conditions on Changes in Physical and Structural Properties of Injection Moulded Parts Made of Polypropylene [PDF]

Archives of Metallurgy and Materials, 2023
The injection moulding conditions may change the degree of crystallinity of the plastic to some extent, which affects the mechanical properties such as tensile strength and hardness. Moreover, the cooling conditions of the moulded parts may contribute to
