A carbon dot-based clay nanocomposite for efficient heavy metal removal
(
Royal Society of Chemistry
, 2023 , Article)
Carbon dots and their derivatives with fascinating photoluminescence properties have recently attracted tremendous scientific attention. This work describes the preparation of novel fluorescent bentonite clay (B), modified ...
Complex treatment of oily polluted waters by modified melamine foams: from colloidal emulsions to a free oil removal
(
Springer Science and Business Media Deutschland GmbH
, 2023 , Article)
This study deals with the efficient, low-cost, and scalable treatment of oily polluted waters including colloidal emulsions, oil-in-water mixtures, and free oil removal using melamine foams (MFs) modified by ferric chloride ...
Impact of the Processing-Induced Orientation of Hexagonal Boron Nitride and Graphite on the Thermal Conductivity of Polyethylene Composites
(
MDPI
, 2023 , Article)
Emergent heat transfer and thermal management applications require polymer composites with enhanced thermal conductivity (κ). Composites filled with non-spherical fillers, such as hexagonal boron nitride (hBN) and Graphite ...
Effect of waste wax and chain structure on the mechanical and physical properties of polyethylene
(
Elsevier B.V.
, 2015 , Article)
The influence of adding waste wax, produced as a by-product of the low density polyethylene manufacturing process, on the thermal and mechanical properties of three types of polyethylene (PE), high-density polyethylene ...
Thermally conductive polyethylene/expanded graphite composites as heat transfer surface: Mechanical, thermo-physical and surface behavior
(
MDPI AG
, 2020 , Article)
Composites of high-density polyethylene (HDPE) and expanded graphite (EG) are prepared for heat exchangers in multi-effect distillation (MED) desalination. At 50 wt.% EG loading, the thermal conductivity of HDPE was increased ...
Modification of polyethylene by RF plasma in different/mixture gases
(
MDPI AG
, 2019 , Article)
Herein, low-density polyethylene (LDPE) films were treated using radio-frequency plasma discharge in the presence of air, nitrogen, oxygen, argon, and their mixtures to introduce new chemical functionalities. The surface ...
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 ...
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 ...
