The influence of direct current electric fields on the possible electrokinetic delivery of nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be introduced to soil hydraulically in slurry form, but in tight clay soil, delivery of a uniform distribution of the slurry may be difficult to achieve for effective remediation....

Fabrication of bioactive and mechanical matched bone substitutes is crucial for clinical application in bone defects repair. In this study, nano-hydroxyapatite/polyamide (nHA/PA) composite was coated on injection-moulded PA by a chemical corrosion and phase-inversion technique. The shear strength, gradient composition and pore structure of the bioactive coating were characterized. Osteoblast-li...

Abstract Excess bisphenol A (BPA) is a pollutant of concern in different water sources. In this work, magnetic illite clay-composite material (Fe3O4@illite) was synthesized via the coprecipitation method by loading Fe3O4 nanoparticles (nano-Fe3O4) onto surfaces clay. Results from characterizations showed that nano-Fe3O4 embedded into clay nanosheets and existed on clay, thereby reducing degree ...

In this experiment the effect of edible coating (apricot gum) was used to extend the shelf life of apple slices. The edible coating was applied at different concentrations i.e. 0.5, 1, 2 and 3%. Physicochemical characteristics of edible coated apple slices were analyzed at different time intervals. The analysis was carried out for 12 days with an interval of 4 days. Results showed that the trea...

Composite edible coatings were formulated with candelilla wax alone, and candelilla wax blended with beeswax, white mineral oil and oleic acid (2:1 ratios) as the lipid phase, and mesquite gum as the structural material and their corrected water vapor permeability (WVPc) were determined. The coatings were applied to Persian limes and their effect upon physiological weight loss, color and chemic...

The effects of coatings based on sodium alginate (S.A) and carboxyl methyl cellulose (CMC) on the color and moisture characteristics of potato round slices were investigated. It is the first time that this combination of polysaccharides is used as edible coating which alone had the best performance as inhibitor of potato color discoloration during the storage of 15 days at 4C. When ascorbic aci...

Abstract PAN-based carbon fiber was surface-modified with silane coating, and a composite material prepared using PI resin as matrix. The structure surface properties of fibers were studied by means X-ray photoelectron spectroscopy (XPS) SEM. tensile strength the measured tester, friction micro-nano mechanics comprehensive test system. results show that treatment coating can improve roughness c...

Nano-materials have been widely accepted for many purposes as improvement materials several engineering projects. In this research, an attempt was made to study the effect of using two types Nano-materials, namely: Nano-SiO2 and Nano-clay, investigate mechanical properties soil improved with aid permeation grouting technique. Three different ratios Nano-materials/ water (1/30, 1/50, 1/100) were...

Maneb is a broad spectrum fungicide, often reported as a carcinogenic, teratogenic and neurodegenerative agent. Thus, the occurrence of maneb at non-targeted sites is a cause of concern. The present study investigates adsorption– desorption behaviour of maneb in the agricultural soils to know its fate, mobility and availability in the soil. The sorption study was carried out by batch equilibrat...

Modified fillers consisting of kaolin particles encapsulated by starch have recently been demonstrated in mill trials to achieve significant filler loading levels without accompanying strength losses. In this work, laboratory experiments were conducted to explore the potential advantages of using starch-treated pigment for strength increases by application of surface coating. It is found that a...
