Background and Objective: In countries such as Iran that are facing with water scarcity and water crisis, paying attention to the quantity, quality and sustainable use of water resources is very significant. Petrochemical processes discharge pollutants into the environment, contaminating surface water resources. Therefore, treatment of the wastewater of these industries is necessary. Due to the...

High emissions from soil fumigants increase the risk of detrimental impact on workers, bystanders, and the environment, and jeopardize future availability of fumigants. Efficient and cost-effective approaches to minimize emissions are needed. This study evaluated the potential of surface water application (or water seal) to reduce 1,3-dichloropropene (1,3-D) emissions from soil (Hanford sandy l...

Aiming to develop more robust, mechanically advanced, Fused Filament Fabrication (FFF) materials, High-Density Polyethylene (HDPE) nanocomposites were developed in the current research work. Titanium Dioxide (TiO2) was selected as filler be incorporated into HDPE matrix concentration steps of 0.5, 2.5, 5, and 10 wt.%. 3D printing nanocomposite filaments extruded ~1.75 mm diameter used print tes...

The effect of blending a small amount high-density polyethylene (HDPE) on molecular entanglements during melt-drawing ultrahigh-molecular-weight (UHMW-PE) was investigated in this study. UHMW-PE powders with HDPE added and bimodal MW distribution were synthesized by reactor blending. In situ wide-angle X-ray diffraction small-angle scattering measurements UHMW-PE/HDPE films performed to evaluat...

Journal: :Cellulose 2023

Abstract This paper aimed to produce a bio-based filament, suitable for 3D printing (fused deposition modeling), made of surface modified cellulose fiber and high density polyethylene. The fibers (CF) were first transformed into CF-based macroinitiator through an esterification reaction with the 2-bromoisobutyric acid. We finally studied ability this initiate single electron transfer-living rad...

Journal: :Fibers 2022

This work aims to produce a 3D-printable bio-based filament composed of high-density polyethylene (HDPE) and chemically modified cellulose nanofibrils. Printing using HDPE as raw material is challenging due its massive shrinkage warping problems. paper presents new method overcome those difficulties by enhancing the mechanical properties achieving better print quality. was achieved nanofibrils ...

Fiber-reinforced polymer (FRP) is the most promising technique in present era to bring sustainability, reliability, and pseudo ductility concrete structures due its superior properties. Thermoplastic thermoset polymers are thrown-out synthetic waste that contributes environmental pollution for a long time. Knowing this issue an attempt was made use High-Density Polyethylene Fiber (HDPE) fillers...
