Rheological and mechanical properties of ultrahigh molecular weight polyethylene/high density polyethylene/polyethylene glycol blends

open access: yesAdvanced Industrial and Engineering Polymer Research, 2019
Ultra-high molecular weight polyethylene (UHMWPE) possesses many excellent properties, but poor processability. There are many ways to improve the processability of UHMWPE, but most of which will compromise its other outstanding properties. The effect of

Plant Design for the Conversion of Plastic Waste into Valuable Chemicals (Alkyl Aromatics)

open access: yesApplied Sciences, 2023
The exponential increase in production and consumption of plastic has led to accumulation of plastic waste in the environment, resulting in detrimental impacts on human health and the natural environment.

Space charge dynamics in low density polyethylene under dc electric fields

open access: yes, 2007
In this paper space charge dynamics in low-density polyethylene (LDPE) under different dc electric fields, ranging from 25 kV/mm to 125 kV/mm, have been investigated using the pulsed electroacoustic (PEA) technique. Bipolar space charges have been formed

Modification of Space Charge Pattern and Charge Mobility of Low Density Polyethylene (LDPE) in the presence of Crosslinking Byproducts [PDF]

open access: yes, 2009
The formation of space charge in Crosslinked Polyethylene (XLPE) cable has always been related to the byproducts such as acetophenone, ?-methylstyrene and cumyl alcohol. In this paper, the argument is to be justified.

Microbial degradation of virgin polyethylene by bacteria isolated from a landfill site

open access: yesSN Applied Sciences, 2022
In this study we evaluate the extent of degradation of high-density polyethylene by bacterial isolates obtained from landfill. The microorganisms are isolated from plastic wastes deposited in the landfill for 2–3 years and 17 years.

MECHANICAL AND PHYSICAL PROPERTIES OF HIGH DENSITY POLYETHYLENE FILLED WITH CARBON BLACK AND TITANIUM DIOXIDE

open access: yesDiyala Journal of Engineering Sciences, 2012
In this work composite material composed of high density polyethylene and inorganic pigment (carbon black and titanium dioxide) was prepared. Different amounts of carbon black and titanium dioxide (2– 15) wt% were added as filler.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Space charge behaviours in polyethylene under combined AC and DC electric fields

open access: yes, 2014
Polyethylene has been one of the widely studied polymeric insulation materials. One of the major issues related to polymeric materials is the easy formation of space charge which may cause electric field enhancement. In this paper, a numerical simulation

Structural Features of High Density Polyethylene Steel-Plastic Tenon Geogrid

open access: yesChemical Engineering Transactions, 2018
By attaching the tenon design to the high-density polyethylene (HDPE) steel-plastic composite geogrid, one new type of geogrid structure named steel-plastic tenon geogrid is designed, which can improve the anti- extraction stability of the grid, further ...
