(
Elsevier Ltd
, 2019 , Article)
This work presents a number of integrated strategies aimed at enhancing the performance of the diesel engine and the subsequent reduction of its associated emissions. Three novel spiral-helical shaped intake manifolds with ...
Polymeric adsorbents for oil removal from water
(
Elsevier Ltd
, 2019 , Article)
In this study, the application of four synthetic resins for the removal of emulsified oil from produced water was investigated. Key experimental parameters such as adsorbent dosage, contact time, initial oil concentration ...
Influence of draw solution type and properties on the performance of forward osmosis process: Energy consumption and sustainable water reuse
(
Elsevier Ltd
, 2019 , Article)
Single and multi-component fertilizers were used as a draw solution (DS) in forward osmosis (FO) to produce high-quality water from synthetic and seawater solution, eliminating the need for DS regeneration and reducing the ...
Photocatalytic conversion of CO 2 and H 2 O to useful fuels by nanostructured composite catalysis
(
Elsevier B.V.
, 2019 , Article)
Cu-TiO2 nano-catalysis were successfully prepared using sol-gel method and used for solar photo-reduction of CO2 in gas and liquid phase. Adding Cu to TiO2 matrix modify its crystalline structure, improved its optical ...
Molecular Dynamic Simulations of Fibrous Distillation Membranes
(
Elsevier Ltd
, 2018 , Article)
The rate of heat and mass transfer through distillation membranes is typically estimated using an over-simplified, straight-cylindrical-pore approach coupled with several empirical correction factors that are included to ...
