In the process of polyethylene extrusion polymer material similar to powder or granule is under compression, melting and transmission operation and on base of special form, extrudate has been produced. Twin-screw extruders are applicable in industries because of their high capacity. The powder mixing with chemical additives and melting with thermal and mechanical energy in three zones (feed, co...

Osteolysis remains the most important problem in orthopedic implant failure. Wear debris from the implant contains polyethylene (PE) particulate which has been shown to activate monocyte-derived macrophages (MDM). Although the response of MDM has been shown to be influenced by the size, shape, and chemical type of PE, the effect of chemically altered PE on MDM has not been studied. In this stud...

Plastics are not easily biodegradable; and because of these characteristics they can remain under landfill and water for a very long period of time. All over the world only 6% of waste plastics are recycled and the rest of all waste plastics are dumped into landfills. An experiment was conducted in a laboratory scale batch process under Labconco’s fume hood utilizing low density polyethylene (L...

Herein, we report the mechanical and piezoresistive sensing performance of 3D printed auxetic nanocomposite structures composed a high-density polyethylene (HDPE) matrix multi-walled carbon nanotubes (MWCNTs). The multifunctional MWCNT/HDPE were measured under tensile loading. results indicate that by varying MWCNT content, as well relative density cell topology (S-shaped, Chiral Re-entrant) st...

The data reported in this paper are complementary to the characterization of 4-(phenylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (AzO-TEMPO) and of the 4-(2-thienylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (ThiO-TEMPO) before and after their grafting to two polyethylene matrices (a copolymer ethylene/α-olefin (co-EO) and a high density polyethylene (HDPE)). Partic...


 The quest to discover more and enhance the qualities of agro-residue for use as natural reinforcement polymers continues attract attention researchers because environmental friendliness. Hyphaene thebaica also known doum palm is a fruit tree native Nile in Egypt found abundance many parts Africa. Doum contains probably hardest toughest nut. nuts (DPN) are most under-used hard-nut despite...

Abstract Plastisphere is a term for any microbial community that grow and develop on the surface of plastic. There was still lot plastics readily disposed in landfills, which would makes it feasible to discover bacteria could decompose plastic be used bioremediation. The present study aims determine number density (colonies) obtainining (bacteria, fungi) isolates from four different types namel...
