Research ArticleOpen accessIn the abstractEnhancing of Copper (II) Adsorption Efficiency by Mixing Plantain and Orange Peelings as Bio-Sorbent SupportSamomssa Inna, Ebelle Epoi Charlotte Alvine, Adjia Zangue Henriette, Sieliechi JosephThe present study focuses on the valorization of plantain and orange peels in the field of water treatment contaminated by heavy metals, especially copper (II). To carry out this study, simplex centroid mixture design was used to determine best mixture from plantain and orange peelings through iodine number, specific surface area and point of zero charge. The influence of contact … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 19 Oct 2020 · 6,920 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption and Descaling of Cellucotton and Chitosan-Modified Bentonite for Produced WaterTao Yu, Ying Wang, Chengtun Qu et al.The compatibility of non-identical layers within the water present in the produced oil is poor and ion reactions in the oil mixed with water result in scale formation, thereby having a significant impact on oilfield safety production. In this study, methods for the descaling of produced water from different blocks were studied according to the quality characteristics of the produced … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 18 May 2020 · 6,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Purification Technology and Antioxidant Activity of Total Flavonoids from Sea Buckthorn LeavesJiale Shan, Yang Liu, Pu Zhao et al.China is rich in sea buckthorn (Hippophae rhamnoides L.)resources and a large amount of sea buckthorn fruit is used to extract oil andjuice every year. However, Sea Buckthorn Leaves (SBL), which are full offlavonoids, are discarded as waste. To make full use of resources and turn waste into valuables, theoptimal purification process of flavonoids from SBL was studied and theantioxidant … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 27 Aug 2022 · 6,073 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption Behavior of Bone Morphogenetic Protein-2 on a Graphite Substrate for Biomedical ApplicationsIzabele Marquetti, Salil DesaiThe interaction of proteins with biomaterials plays an important role for several biomedical applications including implants and tissue engineering. Although different experimental approaches have been explored, the investigation of the molecular models for protein-substrate interaction is warranted to control of cellular functions. In this study, Molecular Dynamics (MD) simulations were used to study the adsorption behavior of Bone Morphogenetic Protein-2 … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 19 Jun 2018 · 8,705 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption and Distribution of Selected High Molecular Weight Polycyclic Aromatic Hydrocarbons in a Typical Coastal Sand DepositUzoije Atulegwu Patrick, Ezenobi Chukwunoye ChristainContaminant migration study through soil medium is a veritable tool for a match towards sustainable groundwater protection. It is also essential to predict the fate and Transport of pollutants and to evaluate pollution risks. In this study, migration and distribution of High Molecular Weight (HMW) Polycyclic Aromatic Hydrocarbons (PAHs) through a coastal sand deposit of a wetland was investigated. Flow … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 27 Mar 2018 · 7,360 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Investigation of Silica Gel-Water Solar Adsorption Cooling System with SimulinkGhilen Najeh, Messai Souad, Gabsi Slimane et al.This paper aims to study a numerical model of an adsorption chiller driven with solar energy that is confronted to experimental measurements.
