Non-equilibrium heat capacity of polytetrafluoroethylene at room temperature [PDF]
, 2007 Polytetrafluoroethylene can be considered as a model for calorimetric studies of complex systems with thermodynamics transitions at ambient temperature. This polymer exhibits two phase transitions of different nature at 292 K and 303 K.

Polyethylene and Polypropylene Nanocomposites Based on Polymerically - Modified Clay Containing Alkylstyrene Units [PDF]
, 2006 Sodium montmorillonite was modified with a new polymeric surfactant. The high molecular weight of the surfactant appears to have led to incomplete cation exchange of the clays, but did promote nanocomposite formation with polyethylene and polypropylene ...

Software Sensors for Biomass Concentration Estimation in Filamentous Microorganism Cultivation Process [PDF]
Chemical and Biochemical Engineering Quarterly, 2019 In this study, the potential of two software sensors for on-line estimation of biomass concentration during cultivation of filamentous microorganisms is examined. The first sensor is based on common bioreactor off-gas analyses, and uses the assumption of

Thermochemistry of yavapaiite KFe(SO4)2: Formation and decomposition [PDF]
, 2005 Yavapaiite, KFe(SO4)2, is a rare mineral in nature, but its structure is considered as a reference for many synthetic compounds in the alum supergroup. Several authors mention the formation of yavapaiite by heating potassium jarosite above ca. 400°C. To
