In this work, rubber nanocomposites based on natural rubber/ethylene propylene diene monomer (NR/EPDM) blends and reinforced with nanosilica (NS) in combination carbon black (CB) barium sulfate (BS) were prepared by melt blending method a Brabender internal mixer. The appropriate contents of NS CB for reinforcing the NR/EPDM are 10 30 phr (parts per hundred rubber), respectively. material has b...

This study aimed to fabricate biodegradable substrate with colorimetric humidity indicator for detective moisture in food packaging. The poor properties of poly(lactic acid) (PLA) were enhanced by melt blending PLA non-toxic poly(ethylene oxide) PEO at 180 °C. Specifically, three-dimensional (3D) substrates PLA/PEO blends fabricated solvent-cast 3D printing. Furthermore, cobalt chloride (CoCl2)...

Abstract The aim of this present work was to study the applicability waste marble dust (MD) in poly(lactic acid) (PLA)-based composites. Samples containing up 20 wt% MD were prepared via melt blending. attention focused on investigation mechanical, morphological, thermal properties and wear resistance PLA/MD Regarding mechanical properties, both tensile flexural modulus improved remarkably, how...

Abstract This study reports on the use of whole seaweed biomass to obtain bio-based films for food packaging applications. Specifically, four different species agarophytes ( Gelidium corneum, Gracilaria chilensis, tenuistipitata and Gracilariopsis longissima ) were minimally processed by melt blending compression molding, effect their composition cell wall structure final performance was invest...

At low temperatures (<750 °C at moderate to high crustal pressures), the production of suffi cient melt to reach the melt connectivity transition (~7 vol%), enabling melt drainage, requires an infl ux of aqueous fl uid along structurally controlled pathways or recycling of fl uid via migration of melt and exsolution during crystallization. At higher temperatures, melting occurs by fl uid-absent...

Two high melt episodes occurred on the Greenland ice sheet in July 2012, during which nearly the entire ice sheet surface experienced melting. Observations from an automatic weather station (AWS) in the lower ablation area in South Greenland reveal the largest daily melt rates (up to 28 cm d−1 ice equivalent) ever recorded on the ice sheet. The two melt episodes lasted 6 days, equivalent to 6% ...
