Natural aging of shape stabilized phase change materials based on paraffin wax
(
Elsevier Ltd
, 2017 , Article)
Natural aging of shape-stabilized phase change materials containing linear low density polyethylene (LLDPE), paraffin wax and expanded graphite (EG) in Qatari climate has been studied. It was found that expanded graphite ...
Recycling of Tetra Pak for Space and Water Heating by Blending with Phase Change Materials
(
Qatar University Press
, 2023 , Conference Paper)
A rapid rise in demands for thermal comfort in the building sector necessitates higher energy consumption for air conditioning, ventilation, space, and water heating systems. Recently, phase change materials (PCMs) have ...
Electrically conductive, transparent polymeric nanocomposites modified by 2D Ti3C2Tx (MXene)
(
MDPI AG
, 2019 , Article)
The electrically conductive, transparent, and flexible self-standing thin nanocomposite films based on copolyamide matrix (coPA:Vestamelt X1010) modified with 2D Ti3C2Tx (MXene) nanosheets were prepared by casting and their ...
Purification of colloidal oil in water emulsions by cationic adsorbent prepared from recycled polyethylene waste
(
Elsevier
, 2024 , Article)
This study deals with removing crude oil droplets from colloidal oil in water emulsions. The target was the development of efficient adsorbents for the tertiary treatment of industrial-produced water (PW). The novel adsorbent ...
Rational synthesis, characterization, and application of environmentally friendly (polymer–carbon dot) hybrid composite film for fast and efficient UV-assisted Cd2+ removal from water
(
Springer
, 2020 , Article)
Background: Carbon dots (CDs) are of particular interest in numerous applications. However, their efficiency for heavy metal removal from wastewater was not yet reported. Herein, we rationally synthesized CDs from petroleum ...
Reverse osmosis silica fouling control with reactive micromixing
(
Elsevier
, 2024 , Article)
Silica fouling is a major challenge in groundwater reverse osmosis (RO) desalination. Dissolved silica, upon concentration during RO, forms a difficult-to-clean glassy foulant layer on membranes, limiting recoveries from ...
Anti-corrosive and oil sensitive coatings based on epoxy/polyaniline/magnetite-clay composites through diazonium interfacial chemistry
(
Nature Publishing Group
, 2018 , Article)
Epoxy polymer nanocomposites filled with magnetite (Fe3O4) clay (B), named (B-DPA-PANI@Fe3O4) have been prepared at different filler loading (0.1, 0.5, 1, 3, 5 wt. %). The surface modification of clay by polyaniline (PANI) ...
