Structures in Sulfur-crosslinked EPDM Analyzed by Hahn Echo Method

Interrelationships of morphology, thermal and mechanical properties in uncrosslinked and dynamically crosslinked PP/EOC and PP/EPDM blends

Thermoplastic vulcanizates (TPVs) based on polypropylene (PP) with ethylene octene copolymer (EOC) and ethylene propylene diene rubber (EPDM) have been developed by coagent assisted dicumyl peroxide crosslinking system. The study was pursued to explore the influence of two dissimilar polyolefin polymers (EOC and EPDM) having different molecular architectures on the state and mode of dispersion ...

An analysis-by-synthesis echo watermarking method

In the conventional echo watermarking methods, the robustness of watermarks could be improved by increasing the amplitudes of the echo signals, or as known as the decay rates, but at the expense of sacrificing audio quality. The objective of this work is to achieve a better audio quality and preserve the robustness of watermarks. Along with the proposed analysis-by-synthesis approach, there are...

EPDM/modified halloysite nanocomposites

Carmine Adsorption from Aqueous Solution by Crosslinked Peanut Husk

To observe the feasibility of the removal of carmine, peanut husk, an agriculture by-product, was crosslinked with epichlorohydrin in alkaline medium and used for adsorption of carmine from aqueous solution. Batch experiments were carried out to study the effects of various parameters such as initial pH, contact time, adsorbent dosage and initial carmine concentration, as ...

Enhanced electrochemical performance of a crosslinked polyaniline-coated graphene oxide-sulfur composite for rechargeable lithium-sulfur batteries

Due to the extraordinarily high theoretical capacity of sulfur (1675 mAh g 1), the lithiumesulfur (LieS) battery has been considered a promising candidate for future high-energy battery applications. LieS batteries, however, have suffered from limited cycle lives, mainly due to the formation of soluble polysulfides, which prevent the practical application of this attractive technology. The enca...
