3D printing of high density polyethylene by fused filament fabrication
TL;DR: In this article, the authors improved Young's modulus, tensile strength and surface quality of 3D printed high density polyethylene (HDPE) by varying 3D printing parameters like temperature and diameter of the nozzle, extrusion rate, build plate temperature, and build plate material.

Nanocellulose Aerogels for Supporting Iron Catalysts and In Situ Formation of Polyethylene Nanocomposites
TL;DR: Aerogels of nanocellulose (NC) prepared by freeze-drying of cellulose nanofibrils hydrogels and followed by impregnation with methylaluminoxane serve as nanoporous organic supports for immobilizing single site iron catalysts such as bisiminopyridine iron(II) complexes as mentioned in this paper.
