Shrinkage, defect and membrane distillation performance of composite PVDF membranes
(Elsevier, 2015-11)This study addresses the importance of non-woven support (NWS) during the preparation of polyvinylidene fluoride (PVDF) membranes for membrane distillation (MD). Five different NWSs were investigated as substrate materials ... -
A simple method for the quantification of free isocyanates on the surface of cellulose nanocrystals upon carbamation using toluene diisocyanate
(Multidisciplinary Digital Publishing Institute, 2019-06)In many reports, cellulose and nanocellulose have been carbamated using 2,4-toluene diisocyanate (2,4-TDI) to allow the grafting of molecules or polymers onto their surfaces. Such a process usually involves the reaction ... -
Soil Aquifer Treatment System Design Equation for Organic Micropollutant Removal
(Springer, 2017)Rapid population growth and mass migration from rural to urban centers have contributed to a new era of water sacristy, and a significant drop in per capita freshwater availability, resulting in the reuse of wastewater ... -
SOLS: A scheme for outsourced location based service
(Academic Press, 2015-10)Due to the high demand on computation and storage, location based service (LBS) providers prefer to outsource their data and services to powerful cloud service providers (CSPs). However, this mechanism brings three challenging ... -
A structural fibrillation parameter from small angle X-ray scattering to quantify pulp refining
(Springer Netherlands, 2019-06)Pulp fibrillation results from refining and is of prime importance for papermaking. Yet a structural parameter reflecting the extent of fibrillation remains elusive. In this work, we demonstrate that in refined pulps, the ... -
A Study on the Application of Artificial Neural Networks on Green Self Consolidating Concrete (SCC) under Hot Weather
(Trans Tech Pub, 2016)Self-consolidating concrete (SCC) has recently drawn attention to the construction industry in hot weather countries, due to its high fresh and mechanical properties. The slump flow is routinely used for quality control ... -
Super-Hydrophobic Polymer/Nanoparticle Composites For The Protection Of Marble Monuments
(2008-04)Water contributes substantially to the degradation of monuments through freezing and thawing cycles and also because it is a carrier of pollutants and salt solutions. Water repellency can be promoted by the application of ... -
Sustainable business through carbon financing with a special reference to UAE banks.
(2019)Green House Gases (GHG) emission creates the global warming. To reduce the consequence of CO2 emissions, many countries contribute to carbon financing through capture and storage process. Through carbon financing, hazardous ... -
Sustainable Development through Carbon Trading Mechanism in the UAE context
(EM International, 2018-07)Sustainable development is considered as a progressive growth of a nation without disturbing the natural resources and carbon trading is defined as a trading process were two different nations exchange or borrow the carbon ... -
Sustainable environmental geotechnics practices for a green economy
(2022-04)The revitalisation of the global economy after the Covid-19 era presents environmental geotechnics with the opportunity to reinforce the need for a change in paradigm towards a green, circular economy and to promote ... -
Swelling and hydrolysis kinetics of Kraft pulp fibers in aqueous 1-butyl-3-methylimidazolium hydrogen sulfate solutions
(Elsevier, 2016-11)1Butyl-3-methylimidazolium hydrogen sulfate ([Bmim]HSO4) is efficient at extracting cellulose nanocrystals from pulp fibers. To shed some light on the respective contributions of swelling and hydrolysis of pulp fibers by ... -
Swelling, viscoelastic, and anatomical studies on ionic liquid-swollen Norway spruce as a screening tool toward ionosolv pulping
(De Gruyter, 2015-11)To screen ionic liquid (IL) candidates for wood ionosolv pulping, swelling and viscoelastic studies on Norway spruce wood treated with ionic liquids have been conducted. In particular, the temperature dependency and kinetics ... -
Synergistic effect of humic acid on alkali pretreatment of sugarcane bagasse for the recovery of lignin with phenomenal properties
(Pergamon, 2020-03)Lignin forms a recalcitrant structure in lignocellulosic biomass and hence huge amount of enzymes are required for disintegrating it into their subsequent components, like glucose and other by-products. Thus, the pretreatment ... -
Synthesis of polydopamine coated tungsten oxide@ poly (vinylidene fluoride-co-hexafluoropropylene) electrospun nanofibers as multifunctional membranes for water applications
(Elsevier, 2022-01)In this work, electrospun poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) nanofiber membranes were loaded with tungsten oxide (WO3) nanoparticles, surface coated with polydopamine (PDA) hierarchical structures, ... -
Tackling membrane fouling in microalgae filtration using nylon 6, 6 nanofiber membrane
(Academic Press, 2018)Microalgae technology, if managed properly, has promising roles in solving food-water-energy nexus. The Achilles' heel is, however, to lower the costs associated with cultivation and harvesting. As a favorable technique, ... -
