Modelling creep responses of plantain fibre reinforced HDPE (PFRHDPE) for elevated temperature applications

open access: yesAdvanced Industrial and Engineering Polymer Research, 2023
The growth in applications of Plantain Fibre Reinforced HDPE (PFRHDPE) has increased the importance of understanding the time-dependent viscoelastic properties such as creep resistance.

Chain-stretch relaxation from low-frequency Fourier transform rheology

open access: yesPhysical Review Research, 2020
Medium- or large-amplitude oscillatory shear (MAOS and LAOS, respectively) is sensitive to polymer chain structure, yet poses unsolved challenges for a priori structural characterization.

Dynamic Master Curves of Polymer Modified Asphalt from Three Different Geometries

open access: yesApplied Rheology, 2003
Polymer modified asphalt is an highly temperature sensitive material. To obtain the master curves of dynamic material functions, for this material, it is necessary to perform the testing over the temperature interval from -30˚C to at least 90˚C. Since in

Rheological Properties of Southern Pine Oleoresins

open access: yesApplied Rheology, 2015
Despite the economic and ecologic importance of pine oleoresins, their rheology remains little explored. In this report we describe rheological properties of oleoresins produced by mature trees of four southern pines native to North America (loblolly ...

Principle of Superposition in Protein-Folding [PDF]

open access: yesarXiv, 2009
We propose a principle of superposition to describe protein-folding nuclei and explain an evolutional conservation of a field pattern specifying native-state structure.

Evidence of intra-chain phase separation in molten short-chain branched polyethylene

open access: yeseXPRESS Polymer Letters, 2011
Intramolecular phase separation is usually associated with block-copolymers, but the same phenomenon is also obtainable by random-copolymers. In this article, evidence of intramolecular phase separation is reported for a linear octadecene-ethene ...

Quantum resource studied from the perspective of quantum state superposition [PDF]

open access: yesarXiv, 2014
Quantum resources,such as discord and entanglement, are crucial in quantum information processing. In this paper, quantum resources are studied from the aspect of quantum state superposition. We define the local superposition (LS) as the superposition between basis of single part, and nonlocal superposition (NLS) as the superposition between product ...

Time–temperature superposition in the grain and grain boundary response regime of A2HoRuO6 (A = Ba, Sr, Ca) double perovskite ceramics: a conductivity spectroscopic analysis

open access: yes, 2017
The pursuit for a universal scaling factor to satisfy the time–temperature superposition principle for grain and grain boundary responses has been explored in the ac conductivity domain for polycrystalline double perovskite oxides A2HoRuO6 (AHR; A = Ba ...

Rheological properties of suspensions with spherical particles in shear and elongational flows

open access: yesApplied Rheology, 2001
The rheological behaviour of model suspensions with spherical particles was experimentally investigated in shear an elongational flows. Particular attention was focussed on the main parameters affecting the flow behaviour of suspensions such as particle ...
