“…In fact, different chemicals and techniques are reported for cleaning up water from oil spills. Examples of the techniques are: adsorption [2], ultra and microfiltration [3], reverse osmosis [4], gravity separation, coagulation, coalescence, skimmers and barriers [5,6]. Materials like foam, highly porous synthetic organophillic sorbents [7], silica aerogels [8], zeolites [9], clays [10], exfoliated graphite [11], graphene frameworks [12], carbon nano tubes [13], cellulose fibre [14], collagen fibres', cellulose lignin polymers etc.…”

Water pollution by oil is a serious environmental problem. Developing new generation of benign adsorbents satisfying several criteria required for real practical application is of great need. This work introduces an effort in this direction, by utilizing a facile synthesis of wood sawdust coated magnetite nanoparticles functionalized stearic acid (WSD@Fe 3 O 4 NPs/SA) as a novel nano composite along with its precursor WSD@Fe 3 O 4 NPs. SA was covalently bonded to the precursor by amide bond formation via the interaction with the silylating agent 3-aminopropyltrimethoxysilane (3-APTS). This mode of binding is more stronger than the conventional ester bond. Fourier transform infrared (FT-IR), X-ray powder diffraction (XRD), Scanning electron microscope (SEM) and Transmittance electron microscope (TEM) were employed for characterization and follow up the synthesis process. Application of the newly synthesized magnetic nano composite adsorbent under optimized parameters of contact time (min) and composite dosage (g) reveal high removal capacity values (g/g) evaluated to be 28.32 g/g, 5 min and 0.1 g for used motor oil removal and 41.22 g/g, 10 min and 0.1 g for crude oil. The high removal efficiency exhibited by WSD@Fe 3 O 4 NPs/SA was mainly argued to the long hydrocarbon chain of SA moiety and additional (CH 2 ) 3 groups incorporated 3-ATPS. Moreover, Analysis of the oil adsorption experimental equilibrium data were well fitted with Freundlish model with correlation coefficients r 2 = 0.9788 and 0.9896 for used motor oil and crude oil, respectively. The kinetic data were correlated using two kinetic models and the results were in harmony with pseudo-second order.

“…In addition to the medical applications, DEP has also been widely used in other industrial applications, such as separating minerals (Ballantyne and Holtham, 2010;Ballantyne and Holtham, 2014;Olariu et al, 2017), self-recovering current limiting fuse (Ohtsuka et al, 2006), depositing a patterned coating of a nanostructure material onto a substrate (Pethig, 2010;Froude and Zhu, 2009), collecting of micron-scale particles (granular, threadlike, sheets, or microelectronic parts) (Pethig, 2010;Allahrabbi et al, 2015), polishing local areas of 3D surfaces using abrasive powders (Pethig, 2010;Kim et al, 2004), biodegradation of organic pollutants in soil (Pethig, 2010;Luo et al, 2005), and in water treatments systems (Pethig, 2010;Abbasi Monfared et al, 2018). During the separating of minerals, DEP is applied at different frequencies and based on the frequency, the polarizability of the mineral particles' changes.…”

Low-cost, highly-sensitivity, and minimally invasive tests for the detection and monitoring of life-threatening diseases and disorders can reduce the worldwide disease burden. Despite a number of interdisciplinary research efforts, there are still challenges remaining to be addressed, so clinically significant amounts of relevant biomarkers in body fluids can be detected with low assay cost, high sensitivity, and speed at point-of-care settings. Although the conventional proteomic technologies have shown promise, their ability to detect all levels of disease progression from early to advanced stages is limited to a limited number of diseases. One potential avenue for early diagnosis is microRNA (miRNA). Due to their upstream positions in regulatory cascades, blood-based miRNAs are sensitive biomarkers that are detectable earlier than those targeted by other methods. Therefore, miRNA is a promising diagnostic biomarker for many diseases, including those lacking optimal diagnostic tools. Electric fields have been utilized to develop various biomedical assays including cell separation, molecules detection and analysis. Recently, there has been a great interest in the utility of electric fields with optical detection methods, including fluorescence and surface plasmons toward biomarker detection. This mini review first summarizes the recent development of miRNA as a biomarker. Second, the utility of electric fields and their integration with fluorescence detection methods will be discussed. Next, recent studies that utilized electric fields and optical detection methods will be discussed. Finally, in conclusion, technology gaps and improvements needed to enable low-cost and sensitive biomarker detection in point-of-care settings will be discussed.

“…A few studies applied electrofiltration to complex water matrices to suggest its effectiveness over foulant mixtures [39,41]. However, it is worth noting that for certain water matrices, the fouling mitigation effect of electrophoresis is relatively marginal, for example, oily wastewater because of its strong fouling capacity [45].…”

Electrofiltration, an electric field-assisted membrane process, has been a research topic of growing popularity due to its ability to improve membrane performance by providing in situ antifouling conditions in a membrane system. The number of reports on electrofiltration have increased exponentially over the past two decades. These reports explored many innovations, such as novel configurations of an electric field, engineered membrane materials, and interesting designs of foulant compositions and membrane modules. Recent electrofiltration literature focused mainly on compiling results without a comprehensive comparative analysis across different works. The main objective of this critical review is to, first, organize, compare and contrast the results across various electrofiltration studies; second, discuss various types of mechanisms that could be incorporated into electrofiltration and their effect on membrane system performance; third, characterize electrofiltration phenomenon; fourth, interpret the effects of various operational conditions on the performance of electrofiltration; fifth, evaluate the state-of-the-art knowledge associated with modeling efforts in electrofiltration; sixth, discuss the energy costs related to the implementation of electrofiltration; and finally, identify the current knowledge gaps that hinder the transition of the lab-scale observations to industry-scale electrofiltration as well as the future prospects of electrofiltration.
