Photopolymer composites filled with cellulose nanocrystal (CNC) and/or inorganic nanofillers were fabricated by using digital light processing (DLP) 3D printing. To investigate the effects of different CNC lyophilization concentrations and behaviors particles in photopolymer composites, morphological mechanical properties analyzed. loading levels affected composites. Better dispersion was seen ...

A novel fabrication of polymer composite fibers using polycaprolactone (PCL), montmorillonite nanoclay (MMT-Clay), and nano-hydroxyapatite-clay (HAP MMT-Clay) is reported for bone tissue engineering applications. Using a pressurized gyration (PG) setup, (PCL) incorporated with in situ mineralized HAP MMT-Clay were investigated. the method, we able to successfully manufacture HAP-nanoclay-PCL fi...

the present article reports on the application of modified organo nanoclay as a green, easily prepared and stable solid sorbent for the preconcentration of trace cobalt ion in aqueous solution. the organo nanoclay was modified by adsorption of 5-(4-dimethyl amino-benzylidene) rhodanin reagent onto it. the sorption of co2+ ions was quantitative in the ph range of 7.0 to 8.5, whereas quantitative...

Foam composite panels made from hybrid fillers are materials developed to have low density with high mechanical properties. This work focuses on improving the properties of epoxy-based foam hybridized by combining hollow glass microspheres (HGM) and nanoclay. The HGM content was varied 1 wt.% 3 in composites panel, while nanoclay 5 each HGM-filled series these were fabricated using a convention...

in the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. the effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. the results show that the effect of nanoparticles on composite ...

research in nanotechnology in the petroleum industry is advancing rapidly and an enormous progress in the application of nanotechnology in this area is to be expected. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening ...

the aim of this work is to probe the influence of nanoclay and turmeric spends content on microcrystalline of vinyl ester hybrid nanocomposites. a series of vinyl ester hybrid nanocomposites have been fabricated with varying amounts of ts viz., 0, 2.5, 5, 7.5 and 10 % w/w along with 2% nanoclay. the microcrystalline parameters such as crystallite size and lattice strain of vinyl ester hybrid na...

Melatonin is a hormone used for treating several disorders. However, its oral administration problematic due to the variable absorption and extensive first-pass metabolism. The topical application of this drug does not present these disadvantages can be therapeutic skin protection purposes. adsorption release melatonin in montmorillonite clay were investigated experimentally theoretically. drug...
