Exchange counterion in polycationic hydrogels: Tunability of hydrophobicity, water state, and floating capability for a floating ph device
(
MDPI AG
, 2021 , Article)
Smart gel materials are capable of controlling and switching swelling, water state, and wettability properties triggered by external stimuli. In this study, we fabricated a series of polyelectrolyte hydrogels bearing a ...
Separation of water/oil emulsions by an electrospun copolyamide mat covered with a 2D Ti3C2Tx MXene
(
MDPI AG
, 2020 , Article)
Purpose: Copolyamide 6,10 (coPA) electrospun mats were covered with multilayered (ML) and single-layered (SL) MXene (Ti3C2Tx) as a membrane for the separation of water/vegetable oil emulsions. Methods: Prepared membranes ...
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 ...
An Enhancement of Compositional Stability of Phase Change Materials by Lamination with Aluminum Sheet
(
MDPI
, 2023 , Article)
The wax leakage from shape-stabilized phase change materials (SSPCMs) is a limitation because it reduces their functionality. In this work, an enhancement of the compositional stability of SSPCMs formed by high-density ...
Alginate-halloysite nanocomposite aerogel: Preparation, structure, and oil/water separation applications
(
MDPI AG
, 2020 , Article)
Environmental remediation using green approaches for addressing various pollution-related issues, especially water pollution, is in high demand. Here, we designed an environmentally friendly, low-cost, and stable sodium ...
Modified os sepiae of Sepiella inermis as a low cost, sustainable, bio-based adsorbent for the effective remediation of boron from aqueous solution
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
The occurrence of boron in low concentration is essential; however, a higher concentration of boron source in water has a toxic effect on humans as well as have retard effect on agricultural plant growth. Thus, the affordable ...
Evaluation of photothermal conversion performance of shape-stabilized phase change materials using a heat flux evolution curve
(
Elsevier
, 2023 , Article)
Phase change materials are promising alternatives for solar energy harvesting by photothermal conversion and thermal energy storage. In this work, a shape-stabilized phase change material (PCM) was prepared by hot-melt ...
Sustainability assessment and techno-economic analysis of thermally enhanced polymer tube for multi-effect distillation (Med) technology
(
MDPI AG
, 2021 , Article)
Metal-alloys tubes are used in the falling-film evaporator of the multi-effect distillation (MED) that is the dominant and efficient thermal seawater desalination process. However, the harsh seawater environment (high ...
Purification of emulsified oily polluted waters with modified melamine foams
(
Elsevier
, 2023 , Article)
Oil and gas industry operations produce tremendous amounts of wastewater (produced water; PW). Tertiary treatment of the PW in the final treatment stage is challenging due to the presence of colloids with sizes < 500 nm ...
Foamed phase change materials based on recycled polyethylene/paraffin wax blends
(
MDPI
, 2021 , Article)
Foamed phase-change materials (FPCMs) were prepared using recycled linear low-density polyethylene (LLDPE) blended with 30 wt.% of paraffin wax (PW) and foamed by 1,1′-azobiscarbamide. The protection of pores’ collapse ...
